Throttling & Fair‑Use Policies: What “Unlimited” Really Means

Travellers love the promise of “unlimited data”, but networks define “unlimited” differently from how most of us use the word. In practice, unlimited plans almost always come with a Fair‑Use Policy (FUP) and speed management rules. Understanding these is the difference between smooth streaming in a hotel lobby and a surprise crawl when you really need maps, ride‑hailing, or boarding passes.

This guide explains unlimited data throttling fair use in plain English. You’ll learn how throttling differs from deprioritisation, the typical caps you’ll see at home and while roaming, how to spot what’s happening on your line, and practical ways to avoid slowdowns on the road. We’ll also flag common gotchas—like hotspot limits and video shaping—that often hide in the small print. Planning a trip? We’ll show you how to pick a plan or travel eSIM with the right fair‑use terms for your usage, whether you’re heading to the US, Spain, Italy or across Western Europe.

What “Unlimited” Really Means Today

“Unlimited” almost never equals “full speed, all the time, for everything.” Most unlimited plans give you:

  • A bucket of high‑priority or full‑speed data (often called premium data)
  • A separate, often smaller allowance for hotspot/tethering
  • A Fair‑Use Policy that applies especially when roaming

Once you hit a threshold—monthly, weekly, or even daily—your speeds may be managed in two distinct ways:

  • Throttling: your line is capped to a fixed, low speed (for example 128 kbps, 512 kbps, or 1–3 Mbps)
  • Deprioritisation: your line stays “unlimited”, but drops in priority behind others when cells are busy

Carriers use both to keep networks stable. For travellers, the impact varies enormously by location and time of day. Understanding unlimited data throttling fair use before you buy prevents surprises once you land.

Fair‑Use Policies (FUP) in practice

FUPs are there to stop unusual consumption that affects other users. Typical patterns we see:

  • Domestic unlimited: 30–100 GB of “premium” data before deprioritisation may kick in
  • Roaming FUP: 5–30 GB at full speed in a foreign country, then slower speeds or deprioritisation
  • Daily high‑speed passes: 1–5 GB per day, then 1–3 Mbps until midnight
  • Hotspot allowances: 5–50 GB at full speed; after that, tethering may be banned or throttled

These are ranges, not promises—always check the plan page. For region‑specific options, browse Destinations or see Esim United States, Esim Spain, Esim France, Esim Italy, Esim Western Europe and Esim North America.

Hotspot and video shaping

Two limits people often miss:

  • Hotspot/tethering: Many “unlimited” plans only include a fixed hotspot allowance. After that, tethering may be slowed or blocked.
  • Video streaming: Some plans cap video at SD (480p) or HD (720p) using traffic shaping, regardless of your available bandwidth.

If you rely on hotspot for work or need HD/4K video, choose a plan that explicitly includes it.

Throttling vs Deprioritisation: Know the Difference

These terms are not interchangeable. Here’s how to recognise each and why it matters.

  • Throttling (speed cap)
  • What it is: A hard limit on your maximum speed once you hit a threshold.
  • When it triggers: After using your premium allowance, or after hotspot/video caps, or during traffic shaping rules.
  • How it feels: Consistently slow across locations and times—e.g., streams drop to SD, large downloads crawl, video calls struggle.
  • Typical numbers: 128–512 kbps for heavy throttles; 1–3 Mbps for lighter management.
  • Deprioritisation (queue position)
  • What it is: Your traffic moves lower in the queue only when the network is congested.
  • When it triggers: After a premium data threshold, or at busy cells (stadiums, stations, city centres at peak).
  • How it feels: Variable. Slow at busy times/places; normal or fast at quieter cells or off‑peak hours.
  • Typical signs: Speed tests vary widely by time and location; uploads may feel especially sluggish in crowds.

Why it matters: If you’re throttled, changing time or place won’t help much. If you’re deprioritised, moving one block, switching to a less loaded band/technology (e.g., 4G to 5G or vice versa), or waiting until off‑peak can restore high speeds.

Typical caps for travellers, by region

These are indicative ranges to help set expectations. Always review plan specifics on the product page.

  • United States / North America
  • Premium data on “unlimited”: commonly 30–100 GB before deprioritisation
  • Hotspot: 5–50 GB at full speed; then slower or disabled
  • Post‑FUP throttle: 128–512 kbps on some budget plans; others keep full speed but deprioritise
  • See Esim United States and Esim North America for travel‑friendly options.
  • Western Europe (EU/UK)
  • Domestic unlimited often very generous; EU‑roam FUPs of 5–35 GB are common
  • Daily unlimited passes: 1–5 GB/day at full speed then 1–3 Mbps
  • Hotspot limits vary; check if tethering is included in the FUP
  • See Esim Western Europe, plus country pages like Esim France, Esim Italy and Esim Spain.
  • Multi‑country trips
  • Regional eSIMs bundle fair‑use per country or per plan. Expect FUPs in the 5–30 GB range for short trips.
  • If you’re a power user, consider stacking plans or selecting tiers with higher premium data.

How to spot slowdowns (and prove what’s happening)

Use this quick, repeatable process:

  1. Check your usage in the app/portal - Look for “premium data used”, “hotspot used”, or “FUP reached” messages.
  2. Run two speed tests - One at a busy time (e.g., 6–8 pm), one off‑peak (early morning). Note ping, download, and upload. - Deprioritisation usually shows big time‑of‑day swings; throttling stays consistently capped.
  3. Toggle network modes - Switch 5G to 4G (LTE), or vice versa. Sometimes a less crowded 4G band beats congested 5G.
  4. Move 100–300 metres - Try a different street corner or side of the building. Cell boundaries and load change quickly.
  5. Test with and without VPN - A VPN won’t fix volume‑based throttles, but it can neutralise app‑specific shaping. Compare results.
  6. Try another device or SIM/eSIM if available - If the second line flies, your original line is likely managed; if both are slow, it’s probably coverage or congestion.

Pro tips: - Record screenshots of usage counters and speed tests. It’s useful if you escalate with support. - If tethering is slow but on‑device usage is fine, you’ve likely hit a hotspot cap.

How to avoid or minimise slowdowns

Follow these steps before and during your trip:

  1. Choose the right plan tier - Prefer plans that advertise “premium data” amounts and explicit hotspot allowances. - For multi‑country trips with heavy usage, consider regional plans like Esim Western Europe or Esim North America with generous FUPs.
  2. Match the plan to your destination - In the US, capacity varies by city and carrier. Travel‑specific options on Esim United States are tuned for visitors. - In Europe, check country pages—Esim France, Esim Italy, Esim Spain—for local FUP details.
  3. Keep hotspot usage intentional - Download large files over hotel Wi‑Fi. - If you must tether, reduce video quality and pause cloud backups.
  4. Optimise your apps - Turn off auto‑updates and background sync while on mobile data. - Pre‑download offline maps and playlists before you fly. - Set streaming apps to 480p/720p on mobile; switch back to higher quality on Wi‑Fi.
  5. Manage your radios - If 5G is patchy, force 4G/LTE to avoid sticky, congested NSA 5G cells. - If upload is critical (video calls), test at different times or locations to dodge deprioritised uplink.
  6. Carry a fallback - Add a second eSIM from a different network in your dual‑SIM phone. When one is congested, switch. - For teams, pooled or centrally managed data on For Business helps ensure reliable capacity.
  7. Read the small print - Look for words like “after X GB, speeds reduced to 1 Mbps,” “video streams at SD,” or “hotspot 10 GB”.

Pro tips: - City centres at lunchtime and early evenings are peak hours. Plan uploads and large downloads for mornings. - Rural areas may have excellent peak speeds but fewer carriers. Keep a secondary eSIM for redundancy.

Heavy‑use and business travellers

If you’re syncing large files, running live demos, or supporting a team:

  • Pick plans with stated premium data allowances and business‑grade hotspot limits.
  • Use dual connectivity: one line for primary data, another as a hot backup.
  • Consider centrally managed solutions via For Business for pooled data and support. Channel or travel partners can explore the Partner Hub.

Checklist: Before you buy an “unlimited” plan

  • Is there a premium data allowance before deprioritisation? How many GB?
  • What is the throttle speed after the FUP is reached?
  • How much hotspot/tethering is included at full speed? What happens after?
  • Is video streamed at a fixed resolution on mobile data?
  • Are the FUP and hotspot limits different when roaming?
  • Can I view real‑time usage counters in an app or portal?
  • What networks and bands are supported at my destination?
  • Does the plan suit my itinerary? Check regional options on Destinations.

FAQ

Q: What’s the difference between throttling and deprioritisation? A: Throttling is a fixed speed cap imposed after you hit a limit (e.g., 512 kbps). Deprioritisation only lowers your queue position during congestion; speeds can still be fast at quieter times or places.

Q: How many gigabytes can I use before I’m slowed on “unlimited” plans? A: It varies by plan and region. Common thresholds are 30–100 GB of premium data domestically, and 5–30 GB when roaming on travel eSIMs. Some plans throttle after that; others simply deprioritise.

Q: Does a VPN bypass throttling or deprioritisation? A: No for volume‑based throttling and deprioritisation—they apply regardless of encryption. A VPN may help only if the network is shaping specific apps (e.g., video), not if you’ve hit a usage cap.

Q: Why is my data slow even before I hit a cap? A: Likely congestion, weak signal, or sub‑optimal bands. Try another location, switch between 5G and 4G, and test at off‑peak times. Compare results to distinguish network load from policy limits.

Q: Is hotspot included in unlimited plans? A: Often in limited amounts (e.g., 5–50 GB). After the hotspot allowance, tethering may be throttled or blocked. Always check the hotspot line item separately from general data.

Q: Will 5G keep me safe from slowdowns? A: 5G can deliver higher peak speeds, but policy still applies. You can still be deprioritised on a busy 5G cell or throttled after hitting a FUP threshold.

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity

Andes Highlights (3 Weeks): Peru–Bolivia–Chile–Argentina Connectivity

Planning a south america itinerary 3 weeks through the high Andes? This route stitches together Peru’s Sacred Valley, Bolivia’s La Paz and Salar de Uyuni, Chile’s Atacama Desert, and northern Argentina’s quebradas or Mendoza wine country—often by long-distance bus and a couple of short flights. Connectivity is different at altitude: coverage is strong in cities but drops in high passes and salt flats; bus Wi‑Fi is patchy; border towns can be blackspots. The smart move is an eSIM with multi‑country coverage, backed by offline maps, offline translations, and a simple routine for crossing borders by bus without losing service. Below you’ll find a practical, connectivity-first itinerary; checklists to prep your phone, apps and documents; and on-the-ground tips for staying online where it matters: booking transport, hailing taxis, backing up photos, and navigating when the signal disappears.If you’re transiting via Europe or North America, you can also add a layover eSIM to stay connected door-to-door. Start with our country list on Destinations, then follow the steps, and you won’t waste time chasing SIM shops at 3,500 metres.The 3‑week Andes route at a glanceWeek 1: Peru (Cusco, Sacred Valley, Machu Picchu) - Fly into Cusco (or Lima then connect). - Base in Cusco; day trips to Pisac/Chinchero/Maras–Moray. - Train to Aguas Calientes; Machu Picchu visit; return to Cusco or continue to Puno/Lake Titicaca.Week 2: Bolivia and Chile (La Paz, Uyuni, San Pedro de Atacama) - Bus/collectivo via Copacabana to La Paz. - Fly or overnight bus to Uyuni. - 3‑day Uyuni–altiplano tour ending in San Pedro de Atacama (Chile).Week 3: Chile and Argentina (Atacama to Salta or Mendoza/Buenos Aires) - Choose: - North: San Pedro to Salta/Jujuy by bus; fly to Buenos Aires. - Or South: San Pedro–Calama flight to Santiago; bus or flight to Mendoza; onward to Buenos Aires.Connectivity notes (quick): - Cities: generally strong 4G/4G+; 5G in major hubs (Santiago, Buenos Aires). - Altitude/rural: expect long no‑signal stretches (Uyuni, altiplano passes, Paso Jama). - Bus Wi‑Fi: often advertised, rarely reliable. Plan to be offline onboard. - Border regions: networks switch; a multi‑country eSIM avoids sudden loss.eSIM vs local SIMs for a 4‑country tripFor a route with multiple borders and remote legs, eSIM wins on time and reliability.What a multi‑country eSIM gets you: - One plan across Peru, Bolivia, Chile, Argentina (check coverage per country on Destinations). - No passport/SIM registration queues at kiosks. - Keep your home number active on the physical SIM for calls/SMS codes. - Instant top‑ups if you burn data on photos or navigation.When a local SIM still helps: - Long stay in one country with heavy data use (e.g., a month in Buenos Aires). - Dead zones where a different local network performs better (rarely worth the hassle on a 3‑week pace).Practical approach: - Use an eSIM as your primary data line across all four countries. - If you find a specific local network far better in one region, add a cheap local SIM and keep the eSIM as backup.Device readiness checklist (before you fly)1) Check eSIM compatibility and SIM‑lock status on your phone.2) Buy and install your eSIM while on home Wi‑Fi. Keep a PDF/printed copy of the QR code.3) Label lines clearly (e.g., “eSIM Andes Data”, “Home SIM”).4) Turn on data roaming for the eSIM; leave roaming off for your home SIM to avoid charges.5) Set up dual‑SIM rules: data on eSIM; calls/SMS default to home SIM if needed.6) Download offline: Google Maps/Organic Maps for all target regions; language packs (Spanish at minimum); bus/air tickets; hotel confirmations.7) Cloud backups: set to upload on Wi‑Fi only; pre‑create shared albums for travel companions.8) Test tethering/hotspot with your laptop/tablet.If you’re transiting popular hubs, consider a short layover eSIM: - USA connections: add an Esim United States or a broader Esim North America.- Europe connections: Madrid/Barcelona? Use an Esim Spain. Paris or Rome? See Esim France and Esim Italy. Multi‑country layovers? Try Esim Western Europe.City‑by‑city connectivity notesCusco & the Sacred Valley (Peru)Coverage: Good in Cusco city; variable in high villages (Maras/Moray) and along Inca Trail approaches.Tips: Download Sacred Valley maps offline; pin viewpoints and ruins. most taxis use WhatsApp—save your accommodation’s number.Machu Picchu/Aguas Calientes: Patchy to none at the citadel. Upload your photos later; don’t rely on live ticket retrieval.Lake Titicaca: Puno and CopacabanaPuno: Reasonable 4G; bus terminals crowded—screenshot QR tickets.Crossing to Copacabana: Expect a signal drop around the border; have directions saved offline.La Paz (Bolivia)Good urban 4G; the cable car network has decent signal but tunnels do not.Yungas/“Death Road” tours: Mountain valleys cause dead zones—share your emergency contacts with the operator, carry a charged power bank, and don’t plan remote calls.Uyuni and the Altiplano (Bolivia to Chile)Uyuni town: OK 4G; ATMs finicky—use Wi‑Fi for banking apps.Salt flats/lagunas: Assume offline for most of the 3‑day tour. Guides often carry satellite phones; agree a pickup time/place in San Pedro and preload your map route.San Pedro de Atacama (Chile)Town: Solid 4G; accommodations often have Wi‑Fi but speeds vary.Geysers, Valle de la Luna: Offline navigation essential; sunrise trips start before mobile networks wake up in some areas.Salta/Jujuy or Mendoza/Buenos Aires (Argentina)Salta/Jujuy: Good city coverage; quebradas have long no‑signal sections.Mendoza: City 4G/5G; vineyards outside town can be patchy.Buenos Aires: Strong 4G/5G; ideal for cloud backups and large downloads before you fly home.Border crossings by bus: step‑by‑stepThe big ones on this route: Peru–Bolivia (Puno/Copacabana), Bolivia–Chile (Uyuni–San Pedro via Hito Cajón), Chile–Argentina (Paso Jama to Salta or Los Libertadores to Mendoza).How to keep service and sanity:1) The day before:- Top up your eSIM data.- Confirm your plan includes both countries you’re entering/leaving.- Download offline maps for both sides of the border and your town of arrival.- Save bus company WhatsApp and terminal address offline.2) On departure morning:- Keep a paper copy or offline PDF of tickets, insurance, and accommodation proof.- Charge phone and power bank; pack a short cable in your daypack.3) On the bus:- Don’t count on bus Wi‑Fi. Keep your eSIM as primary, but expect drops near mountain passes.- If your phone supports it, enable “Wi‑Fi calling” for later when you reach accommodation Wi‑Fi.4) At the border posts:- Data may be unavailable. Keep QR codes and booking numbers offline.- After exiting one country and entering the next, toggle Airplane Mode off/on to re‑register on the new network.- If the eSIM doesn’t attach, manually select a network in Mobile Settings.5) Arrival:- Send your accommodation a quick WhatsApp when you’re back online.- Recheck your eSIM’s data roaming is on; confirm you’re on an in‑country network, not a weak roaming partner.Pro tips: - Dual profiles: If your eSIM allows, keep a secondary profile for a different network in the same country—helpful in border towns.- Cash buffer: Some border terminals don’t accept cards; download a currency converter for offline use.Offline survival kit (5‑minute setup)Maps: Download regions for Cusco, Sacred Valley, Puno, La Paz, Uyuni, San Pedro, Salta/Jujuy or Mendoza, and Buenos Aires.Translations: Download Spanish for offline use; add phrasebook favourites (bus tickets, directions, dietary needs).Documents: Save PDFs of passports, tickets, hotel addresses; star them for quick access.Rides: Screenshots of pickup points; pin bus terminals and hotel doors.Entertainment: Podcasts and playlists for long bus legs, set to download on Wi‑Fi only.Altitude and your tech: what changesCoverage gaps lengthen: Fewer towers at high altitude; valleys can block signal. Assume offline on remote excursions.Batteries drain faster in cold: Keep your phone warm and carry a power bank (10,000–20,000 mAh).Hotel Wi‑Fi may be congested: Schedule big uploads (photo backups, app updates) for big-city stays like Santiago or Buenos Aires.GPS still works offline: Your blue dot shows on offline maps without data—preload everything.Data budgeting for 3 weeksTypical traveller usage across this route: - Messaging/Maps/Bookings: 0.2–0.5 GB/day- Social and photo sharing: 0.3–0.7 GB/day- Occasional video calls/streaming: 0.5–1.0 GB/dayFor a mixed-use trip, plan 15–25 GB for 3 weeks. Heavy creators should double it and upload over hotel Wi‑Fi when possible. If you work remotely, consider a higher‑capacity plan and a backup eSIM; see our guidance on For Business.Practical route with transport and connectivity cuesDays 1–4 Cusco base: Strong city signal; day trips may be spotty—go offline-ready.Days 5–6 Machu Picchu: Expect no service at the ruins; sync tickets ahead.Days 7–8 Puno to La Paz via Copacabana: Border signal drop; re‑register networks after crossing.Days 9–11 Uyuni tour to San Pedro: Treat as offline; charge nightly; carry spare cables.Days 12–14 San Pedro: Stable in town; tours offline; top up data before Paso Jama.Days 15–17 Salta/Jujuy or Mendoza: Good urban 4G; rural patches are offline.Days 18–21 Buenos Aires: Strongest connectivity of the trip; clear your uploads and map downloads for the flight home.Partnering and stopover extrasHospitality and tour operators in the Andes: help your guests stay connected—explore co‑branded solutions via our Partner Hub.Transatlantic flyers: test your eSIM setup on a layover with an Esim United States or Esim Western Europe before hitting high-altitude blackspots.FAQs1) Do I need a local SIM in each country?No. A multi‑country eSIM covering Peru, Bolivia, Chile and Argentina is simpler and works well for a 3‑week pace. Consider a local SIM only if you’ll spend longer in one country and want the absolute best regional coverage.2) Will my WhatsApp number change with an eSIM?No. WhatsApp is tied to your registered number, not your data line. Keep your home SIM active for voice/SMS (roaming off if you wish), and use the eSIM for data—WhatsApp continues as normal.3) Can I hotspot to my laptop or camera?Yes. Enable tethering on your eSIM. Mind your data: cloud backups and OS updates can burn gigabytes—set them to Wi‑Fi only or schedule in big cities.4) What if there’s no signal on the Uyuni/Atacama legs?That’s expected. GPS still works offline. Pre-download maps and translations, carry a power bank, and sync plans with your tour operator before departure.5) Will I get roaming charges at borders?If you’re using a multi‑country eSIM with coverage in both countries, you won’t incur extra roaming fees from your home carrier. Keep roaming off on your home SIM to avoid accidental use.6) I’m connecting via Europe or the US—worth getting a layover eSIM?Yes. It’s an easy way to test your setup and stay reachable. Try Esim North America or country options like Esim Spain, Esim France, or Esim Italy for common hubs.Next step: Browse South America coverage options and build your plan on Destinations.

Student Saver Plans: Semester-Long eSIM Options with Budget Tips

Student Saver Plans: Semester-Long eSIM Options with Budget Tips

Planning a semester abroad shouldn’t mean juggling short-term SIMs or guessing your data needs every few weeks. Simology’s new Student Saver Plans are built for study terms and placements, with long-validity eSIMs that last 90, 120, or 180 days. You get one activation, predictable data, and better value than stacking monthly bundles. Choose single-country coverage (like the US, France, Italy or Spain) or multi-country regional plans (Western Europe or North America) depending on your itinerary. We’ve also streamlined student verification so you can unlock student-only pricing without hassle. Below, you’ll find a quick plan overview, region-by-region guidance, a clear verification flow, installation steps, and practical data budgeting tactics to make your allowance last from orientation to finals. If you’re organising for a cohort or exchange group, there are group options too. Start by checking where you’re headed on our Destinations page, then pick the plan length that matches your term dates.Student Saver Plans at a glance (90 / 120 / 180 days)Think of these as “set-and-forget” eSIMs for the whole term. Each plan gives you a fixed data allowance with long validity and simple top-ups.90 days (Quarter)Best for: Short exchanges, internships, language courses, or mid-term travel.Typical data options: 20–50 GB total, depending on country/region.Good to know: Ideal if you’ll use campus Wi‑Fi heavily and only need mobile data for maps, messaging, and occasional hotspotting.120 days (Semester)Best for: Standard semester abroad or teaching placements that run over three to four months.Typical data options: 30–80 GB total, with optional top-ups if you stream or hotspot.Good to know: The sweet spot for most students—enough headroom for study weeks, weekend trips, and exam crunch time.180 days (Extended Semester)Best for: Extended placements, double-term programmes, or combining study with travel before/after term.Typical data options: 50–120 GB total, with the flexibility to add more if needed.Good to know: Maximum convenience—activate once and forget about expiry until the end of your programme.Pro tips: - If you’re travelling across multiple countries, pick a regional eSIM to avoid swapping. For example, Esim Western Europe for Schengen travel or Esim North America if you’ll be moving between Canada, the US, and Mexico. - Heavy video users (TikTok, YouTube, Reels) should lean towards mid-to-high data options or plan on a mid-term top-up.Choose coverage by destinationPick the footprint that matches your itinerary. You can browse all footprints on Destinations, or jump straight to common student picks:United States: Esim United StatesIdeal if you’ll mostly stay on one US campus with weekend trips.Consider a regional option (Esim North America) if you’ll cross into Canada or Mexico.Western Europe: Esim Western EuropeBest for Erasmus students or anyone city-hopping across Schengen countries.Avoids the need for multiple local SIMs and inconsistent roaming policies.France: Esim FranceGood for single-country study with frequent reliance on campus Wi‑Fi.If you’ll pop into neighbouring countries, consider Western Europe instead.Italy: Esim ItalySolid for city and regional travel within Italy; upgrade to Western Europe for weekend trips to nearby countries.Spain: Esim SpainGreat for students staying in Spain for the term; again, Western Europe suits multi-country travel.North America (regional): Esim North AmericaIdeal for US/Canada exchange pairs and cross-border research trips.When to choose single-country vs regional: - Single-country: You’ll stay mostly in one country and want the best-value per GB in that footprint. - Regional: You plan multi-country weekends or fieldwork. The convenience of one eSIM usually outweighs the slight premium.Student verification: quick and privacy-consciousUnlock student pricing in minutes. Here’s how the verification flow works:1) Create your Simology account - Sign up with the email you actively use. If you already have a university email, use it—it may auto-verify.2) Select your plan - Choose the 90/120/180-day option and your destination footprint.3) Verify your student status - Option A: University email verification - We’ll send a code to your .edu/.ac or institution-issued address. Enter the code to verify. - Option B: Document verification - If you don’t have a university email, upload proof such as your student ID card or current enrolment letter. Ensure your name, institution, and validity dates are visible.4) Get approval - Most email verifications are instant. Document checks typically complete within a business day. We’ll notify you by email.5) Apply discount and checkout - Your student rate is automatically applied. Complete checkout to receive your eSIM activation details.Notes: - Not sure if you qualify? Exchange acceptance letters usually count. If you’re under 18, a guardian can still pay from their account while you verify your student status. - If you’re purchasing for a cohort, see the group options in For Business or partner with us via the Partner Hub.Install and set up your eSIM: 5-minute checklistBefore you leave: - Check that your phone is unlocked and eSIM‑compatible. - Update iOS/Android to the latest version over Wi‑Fi. - Download offline maps for your host city/region (Google Maps, Apple Maps). - Save your eSIM QR code/email and your Simology account login offline.On activation day: 1) Connect to reliable Wi‑Fi. 2) Open your phone’s Mobile/Cellular settings. 3) Add eSIM via QR code or activation code. 4) Label your lines (e.g., “Semester Data” for the eSIM; keep your home SIM as “Home” if you’ll retain it). 5) Set the eSIM as “Mobile Data” and enable “Data Roaming” for the eSIM profile. 6) Keep your home SIM for calls/SMS if needed; set “Default Voice Line” accordingly. 7) Confirm APN settings auto-fill (most devices do this; we’ll include details in your activation email if manual entry is required). 8) Test with a web page and a maps search.Pro tips: - If you plan to retain your home SIM for 2FA, turn off “Mobile Data” for the home SIM to avoid unexpected roaming charges. - Add a data usage widget or shortcut to your home screen so you can check your remaining balance quickly.Budget your data across a semesterStretch your allowance without feeling restricted. Adopt these habits in week one:Lock in your streaming qualitySet YouTube/Netflix/Spotify to “Data Saver” or a capped resolution (480p/720p) on mobile.Disable “Autoplay” on social apps.Control background dataiOS: Low Data Mode on the eSIM line; restrict background app refresh per app.Android: Data Saver + per‑app background data limits.Optimise maps and travel appsDownload offline areas and transit schedules.Cache language packs in translation apps.Messaging and mediaDisable auto‑download for photos/videos in WhatsApp/Telegram/Signal.Use “compress images” options where available.System updates and backupsRestrict cloud backups and OS/app updates to Wi‑Fi only.Pause auto‑upload of photos over mobile data.Hotspot wiselyCap hotspot usage to specific tasks (submitting coursework, cloud sync).Avoid streaming or large updates over tethering.Schedule Wi‑FiFavourites: campus, library, residence halls, cafés you trust.Use a password manager to store Wi‑Fi credentials securely.Track and alertEnable data usage alerts on your device (e.g., warn at 75%, 90%).Check your Simology dashboard weekly; top up proactively before exams or travel weeks.Rough planning guidance: - Light user (messaging/maps/email): 3–5 GB/month. - Moderate (social + some streaming/hotspot): 8–15 GB/month. - Heavy (daily video, frequent hotspotting): 20–30+ GB/month. Match your 90/120/180-day plan to your monthly pattern times the number of months, then add a 10–20% buffer for exam and travel peaks.Top-ups, pauses, and managing your planTop-upsAdd data instantly in your Simology account. Your validity remains; added data rolls into the current term window.Pause/suspendIf you have a mid-term break away from your destination, contact support to discuss options. Eligibility varies by footprint.Data rollover between semestersIf you’re continuing for another term, look for renewal offers. Some footprints support carryover when you renew before expiry.Device changeseSIMs are designed for a single device. If you must change phones mid-term, contact support—we’ll advise based on your device and plan.Fair useLong-validity plans include reasonable use policies to protect network quality.

Private DNS & Safer Browsing on the Road (Without Slowing Down)

Private DNS & Safer Browsing on the Road (Without Slowing Down)

Travelling often means bouncing between hotel Wi‑Fi, café hotspots and mobile data. Each network you join can see, intercept or manipulate your DNS — the phone book lookups your device makes to turn website names into IP addresses. That’s where Private DNS (encrypted DNS) comes in. It wraps those lookups in encryption (DNS over TLS or DNS over HTTPS) so intermediaries can’t snoop or tamper. The result: cleaner, more private browsing with little to no speed penalty.This guide explains how private DNS works, when to use it versus a VPN, and exactly how to enable it on Android, iOS/iPadOS, Windows and macOS. We’ll also cover captive portal “sign‑in” gotchas in hotels and airports, battery impact, and which DNS providers are worth trusting on the road. Combine private DNS with a local eSIM and you’ll avoid flaky public Wi‑Fi entirely in many destinations — see our regional options on Destinations including Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe and Esim North America.What is Private DNS and why travellers should careDNS translates website names into IP addresses. By default, these lookups are unencrypted and readable by anyone running the network you’re on (hotel, café, airport).Private DNS encrypts those lookups:DNS over TLS (DoT): DNS inside a TLS tunnel on port 853 (Android’s “Private DNS” uses DoT).DNS over HTTPS (DoH): DNS inside standard HTTPS on port 443 (supported in Windows 11 and via apps on iOS/macOS).Benefits:Stops local network operators from snooping your browsing destinations.Blocks simple DNS‑level ads/malware if you choose a provider that offers filtering.Reduces risk of DNS hijacking on hostile or misconfigured networks.Limits to understand: - Private DNS does not hide your IP address or encrypt the rest of your traffic — the websites you visit still see your IP, and the network can see the IPs you connect to. For that, use a VPN. - It may interfere with captive portals (those “agree & connect” pages) — easy to work around; see below.Private DNS vs VPN: which should you use on the road?Use Private DNS when:You want lightweight privacy without changing location or routing all data.You’re on mobile data (eSIM/local SIM) and mainly need DNS protection.You want minimal battery and speed impact.Use a VPN when:You’re on untrusted public Wi‑Fi and doing sensitive tasks (banking, work logins).You need to access corporate resources or a specific country’s services.You must protect all traffic metadata, not just DNS.Pro tip: On mobile networks, TLS in apps (HTTPS) already secures content. Pairing that with Private DNS covers the main leak (DNS) without the heavier overhead of a VPN.How to enable Private DNS on your devices (How‑To)Android 9 and newer (DoT)Most modern Android devices support system‑wide Private DNS (DNS over TLS).1) Open Settings > Network & Internet (or Connections on Samsung). 2) Tap “Private DNS”. 3) Choose “Private DNS provider hostname”. 4) Enter one provider hostname (examples): - Cloudflare: 1dot1dot1dot1.cloudflare-dns.com - Google: dns.google - Quad9 (malware blocking): dns.quad9.net - AdGuard (ad/malware filtering): dns.adguard.com 5) Save and reconnect to your network.Notes: - “Automatic” tries encrypted DNS only if your current DNS supports DoT; “Off” reverts to unencrypted DNS. - If a captive portal won’t load, temporarily set Private DNS to “Off”, sign in, then switch it back on.Pro tip: Quad9 is a strong travel choice for malware/phishing protection without logging personal data.iPhone and iPad (iOS 14+ via profile or app)iOS doesn’t have a one‑tap system setting for encrypted DNS. Use a trusted DNS app or configuration profile.Option A — Cloudflare or NextDNS app: 1) Install the “Cloudflare 1.1.1.1” app or the “NextDNS” app from the App Store. 2) Open the app, grant permission to add a VPN/DNS configuration (this is a local device profile, not a full VPN tunnel for Cloudflare’s “DNS only” mode). 3) Enable “DNS‑only” mode (Cloudflare “1.1.1.1” without Warp) or choose your NextDNS profile. 4) Leave the app enabled; it will enforce DoH across apps.Option B — Install an encrypted DNS profile: 1) Create a profile with a provider (e.g., NextDNS web dashboard). 2) Download and install the mobile configuration profile in Settings > General > VPN & Device Management. 3) Verify the profile is active.Captive portal tip: Toggle the DNS app off, complete the Wi‑Fi sign‑in, then re‑enable.Windows 11 (DoH)1) Settings > Network & Internet > Wi‑Fi (or Ethernet) > Hardware properties. 2) Edit DNS server assignment > Manual. 3) Enable IPv4 (and IPv6 if you use it). 4) Enter DNS addresses (e.g., 1.1.1.1 and 1.0.0.1 for Cloudflare; 9.9.9.9 and 149.112.112.112 for Quad9). 5) Set “Preferred DNS encryption” to “Encrypted only (DNS over HTTPS)”. 6) Save. Reconnect to the network.Quick verify: Visit your provider’s test page (e.g., Cloudflare’s “Help” page) to confirm DoH is active.macOS (Big Sur and newer)macOS supports encrypted DNS via configuration profiles or apps.Option A — Use an app (simplest): 1) Install Cloudflare 1.1.1.1 or NextDNS app for macOS. 2) Grant permissions to add a DNS profile. 3) Enable DNS‑only mode (Cloudflare) or your NextDNS configuration.Option B — Install a DNS profile: 1) Generate a DoH/DoT profile from your provider (e.g., NextDNS). 2) Install via System Settings > Privacy & Security > Profiles (or Profiles in System Preferences on older macOS). 3) Apply to active network services.Captive portal tip: Pause the app/profile temporarily to complete hotel/airport sign‑in pages.Captive portals: the gotcha and the fixEncrypted DNS can prevent captive portals from redirecting you to the sign‑in page because the network expects to intercept DNS. Here’s how to handle it smoothly:Join the Wi‑Fi network.If the login page doesn’t appear within 10 seconds:Android: Settings > Network & Internet > Private DNS > Off. Then re‑open your browser and go to http://neverssl.com to trigger the portal.iOS/macOS: Pause your DNS app/profile. Try http://neverssl.com or open the Wi‑Fi network’s info and tap “Join Network”/“Login”.Windows: Temporarily switch encryption to “Unencrypted only” or disable your DNS tool; reconnect and sign in.Once you’re online, re‑enable Private DNS.Pro tips: - Some networks re‑check the portal after idle time; keep the DNS tool handy to toggle. - If the portal still won’t load, “Forget” the network and try again with Private DNS off until authenticated.Will Private DNS slow me down or drain battery?Speed: - The overhead of DoT/DoH is tiny after the first handshake. With anycast networks (Cloudflare, Google, Quad9), latency is comparable to or better than many hotel DNS servers. - DoH may add a fractionally higher CPU cost than plain DNS, but it’s negligible on modern devices. - Pick a nearby, reputable provider to avoid detours.Battery: - Private DNS maintains lightweight encrypted sessions; the impact is minimal, far less than a full VPN. - VPNs keep an always‑on tunnel with regular keep‑alive traffic and packet processing — expect noticeably higher battery drain. - On mobile data, modern radios dominate battery use; private DNS won’t be the deciding factor.Testing tip: Use a DNS benchmark app or “dig” from a laptop tethered to your phone to compare latency before and after.Choosing a trusted DNS providerLook for a clear privacy policy, broad global footprint, and (if desired) security filtering:Cloudflare (1.1.1.1): Fast, strong privacy stance, no content filtering by default. DoT: 1dot1dot1dot1.cloudflare-dns.com. DoH supported widely.Google (8.8.8.8): Globally fast and reliable; transparent but different privacy model from Cloudflare.Quad9 (9.9.9.9): Security‑focused with threat blocking, non‑profit; strong choice for travellers wanting extra protection.AdGuard DNS: Optional ad/malware blocking; privacy‑friendly.NextDNS: Highly configurable filtering, logs you control; requires a personalised profile.Pro tip: For family devices, NextDNS/AdGuard can block trackers and malicious domains while travelling, reducing risky clicks on unfamiliar networks.A practical travel checklistBefore you fly: - Update your device OS and apps (security patches). - Set up Private DNS or install your DNS app/profile. - Save provider hostnames or app toggles for quick captive portal workarounds. - Add a lightweight VPN for when you must trust public Wi‑Fi. - Consider a local eSIM so you can skip public Wi‑Fi altogether; browse regional options on Destinations — including Esim Western Europe and Esim North America.On the day: - Prefer mobile data where possible. If you’re heading to the US or Europe, check Esim United States, Esim France, Esim Italy and Esim Spain. - On Wi‑Fi, enable Private DNS; toggle off only briefly for captive portals. - Use a VPN for banking or work portals on public Wi‑Fi. - Avoid installing random “Wi‑Fi booster” apps; stick to reputable DNS/VPN tools.For teams and partners: - Business travellers can standardise encrypted DNS and eSIMs through our For Business solutions. - Travel providers and IT resellers can collaborate via our Partner Hub.When you still need a VPN (even with Private DNS)Accessing corporate networks or region‑locked services where location matters.Using truly untrusted or tampered networks (e.g., conferences, shared coworking).Hiding destination IP metadata from local network operators.Enforcing security policies across all traffic for a business fleet.Private DNS protects DNS queries; a VPN protects the entire session. It’s fine to run both when needed — start with Private DNS by default, escalate to VPN for sensitive sessions.FAQDoes Private DNS change my location like a VPN?No. It only encrypts DNS lookups. Your IP address and approximate location remain the same.Will Private DNS break streaming or apps while travelling?Rarely. Some hotel or airline networks require their own DNS; if something fails, temporarily switch Private DNS off, then back on after login/stream start.Is DoT or DoH better for travel?Both are secure. Use what your device supports natively: Android prefers DoT; Windows 11 uses DoH. Performance differences are negligible.Can I use Private DNS on cellular data with an eSIM?Yes. It works on any network type. Pairing Private DNS with a local eSIM gives private, fast lookups without relying on risky public Wi‑Fi. See regional options on Destinations.Which DNS provider should I pick?For speed and privacy: Cloudflare or Google. For added threat protection: Quad9. For custom filtering/log control: NextDNS. Stick to one you trust.Does Private DNS save battery compared to a VPN?Yes. It has a much smaller battery impact because it encrypts only DNS, not all traffic.Next step: Set up Private DNS on your devices today, then choose a local eSIM for your next trip on Destinations so you can rely on mobile data instead of risky public Wi‑Fi.
