EU Roam Like at Home (2025): Fair‑Use Data Limits & Surcharges Explained

29 Oct 2025

Roam Like at Home (RLAH) lets you use your domestic mobile plan across the EU/EEA at your home rates. But there’s a catch many travellers miss: fair‑use policy (FUP) limits for data, and small surcharges once you go over. In 2025, the EU’s cost caps change again, which nudges your minimum roaming data allowance up if your provider applies a FUP cap. This guide gives you a plain‑English calculator you can actually use, realistic examples for light/standard/heavy users, and a checklist to avoid bill shock. We also link straight to the official EU rules, and we update this page (with a banner) whenever the numbers change.

If your trip includes non‑EU stopovers like Switzerland, the UK, Andorra or Monaco, your RLAH rights don’t apply there. See where your plan or an eSIM makes more sense on our live country pages: Destinations. If you need simple, borderless cover across multiple EU countries, a regional eSIM such as Esim Western Europe keeps costs predictable.

Where RLAH applies in 2025

RLAH covers EU member states plus Iceland, Liechtenstein and Norway. It also includes EU outermost regions such as the Canary Islands, Madeira/Azores, and French overseas departments (e.g., Guadeloupe, Réunion, Martinique, French Guiana, Mayotte, Saint‑Martin FR).

It does not automatically cover: - Switzerland, the UK, Andorra, Monaco, San Marino or the Channel Islands/Isle of Man - Microstates not part of the EU/EEA

Some networks voluntarily include nearby non‑EU places in “Europe” bundles—check your operator. If your route is mixed‑region, consider an eSIM covering the gaps. For example: - Crossing the Schengen belt? Esim Western Europe - US trip before/after the EU? Esim United States or Esim North America - Planning France, Italy, Spain city‑hops? See Esim France, Esim Italy and Esim Spain

The 2025 fair‑use rule changes in one minute

Wholesale data cap falls to €1.30/GB (ex VAT) from 1 January 2025.
That number matters because operators use it to calculate the minimum roaming data allowance on unlimited/very‑cheap bundles.
If you exceed your fair‑use allowance (or are flagged for long‑term roaming), providers can add small surcharges, capped at EU‑regulated rates.

The 2025 surcharge caps (maximums)

These are the most your operator can add on top of your normal domestic rate if a fair‑use cap kicks in. All are ex VAT; local VAT is added on your bill. - Data: up to €1.30 per GB - Voice calls: up to €0.022 per minute (outgoing while roaming) - SMS: up to €0.004 per message (outgoing while roaming)

Incoming calls while roaming in the EU should follow your domestic reception conditions (typically free).

Plain‑English calculator: your minimum EU roaming data under FUP

Use this if: - Your domestic plan is unlimited, or - Your plan is very cheap per GB and your operator applies a fair‑use cap while roaming

Step‑by‑step: 1) Find your monthly bundle price without VAT
- If your bill shows €24 with 20% VAT, the ex‑VAT price is €24 / 1.20 = €20.

2) Apply the 2025 formula
- Minimum roaming data (GB) = 2 × (Monthly ex‑VAT price) ÷ 1.30

3) Round down to a sensible whole number (operators often do).

Quick examples (2025): - €10 ex VAT plan: 2 × 10 ÷ 1.30 ≈ 15.3 GB - €15 ex VAT plan: 2 × 15 ÷ 1.30 ≈ 23.0 GB - €20 ex VAT plan: 2 × 20 ÷ 1.30 ≈ 30.7 GB - €30 ex VAT plan: 2 × 30 ÷ 1.30 ≈ 46.1 GB

Important: - This calculator estimates the minimum data your operator must allow if they apply an “open‑bundle” fair‑use cap (typical for unlimited plans). Your operator can be more generous, but not stingier than the formula. - If your plan has a fixed domestic data cap (e.g., 5 GB, 30 GB), you can usually use that full allowance while roaming at domestic rates. Some very cheap large bundles may still be treated as “open” and be capped using the above formula—check your plan’s roaming terms.

How operators apply fair‑use (and why you might see a cap)

Open data bundles: Unlimited or very cheap data plans can be capped for EU roaming using the calculator above. Once you hit the cap, surcharges may apply for more data in the same billing period.
Fixed data bundles: Most users can use up to their domestic data limit while roaming. If the domestic limit is higher than the calculator result and your plan is priced unusually low, your operator may still set a roaming cap around the calculator result.
Long‑term roaming: If you spend more time abroad than at home and use more data abroad over a 4‑month window, your provider can warn you. If your usage pattern continues, they may apply the regulated surcharges. This is to stop permanent roaming on a cheaper foreign SIM.

Pro tips: - Always check the roaming annex of your plan: it will state your EU roaming data allowance and any fair‑use limits. - Watch how your provider counts a “month”—billing cycle vs calendar month can affect when your cap resets. - If crossing non‑EU borders mid‑trip, keep your phone in flight mode until you confirm you’re in an RLAH country, or switch to a regional eSIM.

Real‑world examples: light, standard and heavy users

These scenarios assume 2025 caps and common operator practices. Your own plan may differ—always confirm your exact allowance in your account or app.

1) Light user: 5 GB domestic cap, €12/month (incl. VAT 20%)
- Domestic allowance: 5 GB
- Ex‑VAT price: €12 / 1.20 = €10
- Calculator result: ≈ 15 GB (but you don’t have unlimited)
- Likely EU roaming allowance: 5 GB at domestic rates (because your domestic cap is 5 GB).
- Beyond 5 GB: your operator may block or charge overage/surcharges—check your plan.

2) Standard user: 50 GB domestic cap, €24/month (incl. VAT 20%)
- Domestic allowance: 50 GB
- Ex‑VAT price: €24 / 1.20 = €20
- Calculator result: ≈ 31 GB
- Likely EU roaming allowance: Either the full 50 GB or around 31 GB if your operator treats it as an open/very‑cheap bundle. Many mainstream plans allow the full 50 GB; budget plans may cap closer to the calculator.

3) Heavy user: Unlimited domestic data, €36/month (incl. VAT 20%)
- Ex‑VAT price: €36 / 1.20 = €30
- Calculator result: ≈ 46 GB
- Likely EU roaming allowance: About 46 GB at domestic rates. After that, your provider may add up to €1.30/GB (ex VAT) or throttle per policy.

4) Frequent traveller flagged for long‑term roaming
- If your usage is predominantly abroad for 4+ months, expect a warning SMS. Keep roaming heavily abroad and the operator can add the capped surcharges even before you hit your data allowance.

If you need more guaranteed data across multiple borders, a travel eSIM with simple tiers can be cheaper and clearer than chasing FUP fine print. Compare regional options via Destinations or go straight to Esim Western Europe.

What happens when you exceed the fair‑use allowance?

Data: Your operator can add up to €1.30 per GB (ex VAT) on top of your domestic rate, until your billing period ends or a higher cap/add‑on applies. With 20% VAT, that’s up to €1.56/GB on your bill.
Voice: Up to €0.022/min (ex VAT) for outgoing calls while roaming, if a FUP on calls applies.
SMS: Up to €0.004 per message (ex VAT) for outgoing texts while roaming, if a FUP on SMS applies.
Notifications: Operators must inform you when you approach and reach your data fair‑use limit, and when surcharges begin.
Add‑ons: Many providers sell EU roaming bolt‑ons that reset or increase your allowance. Compare the per‑GB price of an add‑on vs the regulated surcharge; sometimes the surcharge is already the cheapest route, sometimes not.

Pro tips: - Turn off automatic cloud backups, app auto‑updates and high‑bitrate streaming while roaming. - Download maps/playlists on Wi‑Fi before crossing borders. - If you’re heading beyond the EU/EEA (e.g., US), set up a separate eSIM like Esim United States to avoid out‑of‑bundle roaming.

Traveller checklist: do this before you go

Confirm your plan type: Fixed data cap or unlimited? Note the monthly price ex VAT.
Find your EU roaming data allowance: In your carrier app or T&Cs. If “unlimited at home”, check the EU FUP value explicitly.
Calculate your minimum: Use 2 × (ex‑VAT price) ÷ 1.30 to estimate the floor for 2025 if your plan is unlimited/very cheap.
Set data alerts: Enable data‑use notifications at 80% and 100% in your phone and carrier app.
Save key contacts offline: Booking codes, accommodation, travel insurance PDFs.
Cover non‑EU gaps: Add a regional eSIM if your route includes Switzerland/UK/Andorra/Monaco—browse Destinations.

For teams and frequent flyers

If you manage staff on the road, align policies with EU fair‑use to control costs. Options: - Standardise plans with transparent EU FUP terms - Add travel eSIMs for non‑EU legs or heavy‑data roles - Centralise provisioning and spend alerts

FAQ: EU Roaming Fair Use 2025

1) How do I know what VAT rate to use in the calculator?
Use the VAT of the country where your mobile contract is billed (shown on your invoice). To get the ex‑VAT price, divide your total by 1 + VAT rate (e.g., 1.20 for 20% VAT).

2) Does RLAH cover Switzerland, the UK, Andorra or Monaco?
No. RLAH rights only apply in the EU/EEA. Some carriers include these places voluntarily, but it’s not guaranteed. If they’re on your itinerary, consider a regional eSIM or local plan—see Destinations.

3) Are tethering and 5G included when roaming?
Generally, your roaming experience should match your domestic plan (including tethering and 5G) where technically feasible on the visited network. Some operators restrict hotspot use or cap speeds—check your plan’s roaming section.

4) Will I be charged for incoming calls in the EU?
Incoming calls while roaming in the EU/EEA should mirror your domestic reception conditions (typically free). Outgoing calls and SMS can incur small surcharges only if a FUP is triggered.

5) What changes on 1 January 2025?
The wholesale data cap falls to €1.30/GB (from €1.55 in 2024). That increases the minimum roaming data allowance on unlimited/very‑cheap plans when a fair‑use cap is applied, and lowers any per‑GB surcharges. We update this guide—and display an update banner—whenever the EU changes the caps.

6) I travel every week across borders. How do I avoid long‑term roaming surcharges?
Ensure your usage remains predominantly at home over any 4‑month window, or consider a travel eSIM for the roaming leg so your home SIM isn’t flagged. Business travellers with constant cross‑border use can benefit from dedicated roaming bundles—see For Business.

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.

Indonesia SIM Registration for Foreigners (2025): Passport, Tax ID & Where to Register

If you want a local data plan in Indonesia, you must register your SIM. For tourists in 2025, the essentials are straightforward: bring your passport, buy from an official outlet, and (if you plan to use a local SIM) register your phone’s IMEI with Customs on arrival. Registration is fast when you do it in the right place—airport counters or flagship stores for Telkomsel, XL Axiata and Indosat (IM3). Corner shops and unbranded kiosks can sell a SIM but often can’t complete foreigner registration, which is why many travellers end up with a non-working card until they visit a carrier store.You do not need an Indonesian tax ID to buy a SIM as a tourist. A local Tax ID (NPWP) is a resident requirement only. Expect instant activation once your passport and device details are captured, though some lines take up to a few hours. This guide explains exactly where to go, what to bring, how long it takes, and common snags to avoid. For a broader view of connectivity across the region, see our country pages under Destinations.Quick facts: 2025 rules at a glanceWho must register: Everyone using an Indonesian SIM, including tourists.IDs accepted for tourists: Passport (photo page). Some outlets also request your entry stamp/visa.Tax ID (NPWP): Not required for tourists. May be requested for residents with KITAS/KITAP.Where to register: Airport operator counters or official city stores (GraPARI for Telkomsel, XL Center, Indosat/IM3 Gallery).IMEI rule: If you’ll use a local Indonesian SIM, register your phone’s IMEI with Customs on entry.Time to activate: Usually minutes; allow up to 24 hours in edge cases.Number of SIMs per ID: Operators may cap how many numbers can be linked to one passport. Expect a small limit.Best coverage: Telkomsel generally leads for nationwide coverage, especially off the beaten path.Indonesia SIM registration for tourists: what you need in 2025To complete indonesia sim registration tourist requirements, you typically need:Passport: The physical passport you used to enter Indonesia. Staff will scan or photograph it.Entry details: Your entry stamp or visa (e.g., VOA/e-VOA) may be requested.Local contact info: A temporary address (hotel/Airbnb) and Indonesian phone contact are sometimes asked but not always enforced.Your phone: Keep it handy for SIM insertion, eSIM provisioning (where available), and test calls/data.IMEI registration: If using a local SIM, Indonesian Customs needs your device IMEI recorded when you arrive.Good to know: - Photocopies aren’t usually required; a physical passport is. - Staff complete the registration in their system. Tourists cannot complete the standard NIK/KK self-registration used by locals. - Some flagship stores issue eSIM profiles to eligible devices; availability and staff policy varies by location.Where to register: airport kiosks vs city storesBuying at the right place matters more than hunting the cheapest shelf price.Airport operator counters (best for immediate connectivity)Pros:Passport registration is done on the spot.Staff can help with IMEI questions and basic setup.English-speaking staff are common in major airports (CGK Jakarta, DPS Bali).You walk out connected.Cons:Packages can be pricier than in town.Stock may be limited during peak arrivals.Official city stores (often best value)Pros:Full service: SIM sale, passport registration, troubleshooting, eSIM availability in flagship branches.Broader plan selection, often better value than airports.Cons:Requires a trip across town and queue time.Opening hours vary; not 24/7.Look for: - Telkomsel GraPARI - XL Center - Indosat Ooredoo Hutchison (IM3) GallerySmall kiosks and convenience stores (proceed with caution)Pros: Cheapest sticker price, everywhere.Cons: Many cannot legally register a foreign passport. You may leave with a SIM that won’t activate until you visit an operator store. Not worth the risk for short stays.Step-by-step: from landing to connected1) Decide your approach- If you only need calls/data for a day or two and you already have roaming or a regional eSIM, you may skip a local SIM entirely.- If you want local rates for a week or more, a registered local SIM is usually best value.2) Register your device IMEI with Customs (if using a local SIM)- Before or on arrival, prepare your phone’s IMEI numbers (dial *#06#).- Use the Mobile BeaCukai app or the customs desk at the airport to submit your device details. You’ll be given a confirmation/QR code.- Present the QR/approval at the counter if asked. Tourists generally receive time-limited permission to use a local SIM on that device.- If you forget at the airport, visit a Customs office soon after arrival. Using international roaming does not require IMEI registration.3) Choose an operator- Telkomsel: Widest coverage, especially outside big cities and across islands.- XL Axiata: Good urban coverage and competitive pricing.- Indosat (IM3): Often attractive data bundles and promos.Tip: Ask specifically for a “tourist” or “foreigner” package and confirm voice/SMS inclusions if you need them.4) Buy and register at an official counter- Present your passport (and entry stamp if requested).- Staff will capture your details, insert the SIM or issue an eSIM, and complete registration in the operator’s system.- You may be asked for a local address (hotel is fine).- Keep the SIM starter pack and receipt; they include your number and useful USSD codes.5) Activate and test- Restart your phone after SIM/eSIM provisioning.- Check mobile data, calls, and SMS. APN settings usually configure automatically.- If data doesn’t work immediately, toggle airplane mode, then try a manual network selection.Costs, plans and activation timelinesPricing shifts regularly, but as a guide:Starter packs: IDR 50,000–150,000 for basic data with some local calls/SMS.Tourist bundles: IDR 100,000–300,000 for larger data (e.g., 15–35 GB) and bonus app data or local minutes.eSIM: Offered by some operator flagships; priced similarly to physical SIMs.Activation speed: - At an official counter, your line typically goes live within minutes once registration is submitted.- Network provisioning can take longer in busy periods; allow up to a few hours. Rarely, 24 hours.Top-ups and extensions: - Use the operator’s app (requires your Indonesian number for OTP), vouchers from minimarts (Indomaret, Alfamart), or pay at an operator store. - Tourist lines may have validity limits aligned to your stay. Ask how to extend if you’re in-country longer.Common snags (and how to fix them)SIM shows “emergency calls only” or no service:Check that IMEI registration was completed if you’re using a local SIM.Try manual network selection (Telkomsel/XL/Indosat) and restart the phone.Bought at a small kiosk and it won’t activate:Visit an official operator store with your passport to complete foreigner registration.No data despite signal bars:Toggle airplane mode, reset network settings, or update APN to default for your operator.Confirm your bundle includes data and is active.eSIM failed to install:Ensure you’re on stable Wi‑Fi, scan the QR again, or ask staff to reissue the profile. Some outlets can only issue physical SIMs to foreigners.Line deactivated mid-trip:It can happen if IMEI wasn’t registered or your package validity expired. Visit an operator store with your passport.WhatsApp number change:If you switch from a roaming number to a local number, use WhatsApp’s Change Number feature to keep chats and groups.Passport vs Tax ID (NPWP): what you actually needTourists: Passport only. You will not be asked for a local Tax ID (NPWP) to buy/register a SIM as a short-stay visitor.Residents and long-stay permit holders: Some outlets may request KITAS/KITAP and NPWP. Requirements vary by operator and tenure.If staff mention “NIK/KK”: Those are local IDs for Indonesians. As a foreigner, your passport is used instead.Business travellers and teamsNeed multiple lines, consistent packages, or centralised spend?

NPWP is for residents and is not a requirement for short-stay visitors.2) Is IMEI registration mandatory for tourists?If you plan to use a local Indonesian SIM, you should register your device IMEI with Customs on arrival. Roaming on your home SIM does not require IMEI registration. Airport customs counters can handle this in minutes.3) Can I register my Indonesian SIM online?Not as a tourist. Foreigners must complete registration in person at an official operator outlet (airport counters or flagship stores) where staff scan your passport and submit the registration.4) How long does SIM activation take?Usually within minutes after staff complete registration; sometimes up to a few hours. Very occasionally, it may take until the next day.5) Can I get an eSIM as a tourist in Indonesia?Some flagship operator stores can issue eSIMs to eligible devices, but availability varies by city and store. Airport counters often favour physical SIMs. Ask the outlet in advance if you specifically want eSIM.6) How many SIMs can I register with one passport?Operators may limit the number of active numbers linked to a single passport. Policies vary; expect a small cap and ask the staff if you need more than one line.Next stepPlanning your trip and want the latest local guidance and plan options?

Pocket WiFi vs eSIM: Which Is Better (and Cheaper) for Travel?

Travellers weigh “pocket WiFi vs eSIM” for the same reason: reliable data at a fair price with minimal faff. Both connect you to local 4G/5G networks; the difference is how. A pocket WiFi is a rented hotspot you carry and charge, while an eSIM is a downloadable data plan that lives in your phone. This guide cuts through marketing to compare real‑world costs per GB, speed and latency, security risks, and multi‑device sharing. You’ll also find quick setup steps, a 60‑second chooser checklist, and regional notes for the United States, Western Europe and North America.Short answer: eSIMs are usually cheaper per GB, faster to set up, and easier to manage. Pocket WiFi can still suit groups who need to share to many devices or travellers with older/locked phones. If you’re eSIM‑compatible, a travel eSIM will cover most trips with less to carry, fewer fees, and better control over usage.Explore country and regional plans on Destinations.Quick verdict: who should pick what?Choose eSIM if:You have an eSIM‑compatible and unlocked phone.You value cost control (buy exactly the data you need).You want faster setup (scan and go) and no device returns.You’ll hotspot a handful of devices (check tethering is allowed).Choose pocket WiFi if:Your phone does not support eSIM or is carrier‑locked.You need to share to 8–10+ devices all day without draining your phone.Your employer mandates separate networking hardware.Tie-breakers:Battery: eSIM uses your phone’s battery; pocket WiFi is a second battery to manage.Loss risk: eSIM cannot be “lost”; pocket WiFi loss/damage fees can be steep.Coverage: both ride the same local networks. With eSIM you can pick plans that use top carriers in your destination (e.g. Esim United States, Esim France).Cost comparison: pocket WiFi vs eSIMThe biggest hidden difference is total cost per GB once you account for deposits, delivery/return, and “unlimited” fair‑use caps on pocket WiFi.Typical retail price/GB (indicative ranges)These are common market ranges for tourists buying short‑term plans. Always check current pricing for your destination on Destinations.Region / CountryeSIM price/GB (typical)Pocket WiFi effective price/GB (typical)NotesWestern Europe$1.5–3/GB$2.5–8/GB“Unlimited” WiFi often has 1–5GB/day high‑speed, then throttled. See Esim Western Europe.France / Italy / Spain$1.5–3/GB$2–6/GBStrong competition; local eSIMs are very cost‑effective. See Esim France, Esim Italy, Esim Spain.United States$3–6/GB$4–10/GBPocket WiFi often adds delivery and loss fees. See Esim United States.North America (US/CA/MX)$2.5–5/GB$5–12/GBRegional roaming on hotspots costs more. See Esim North America.How we think about “effective price/GB”: - Pocket WiFi day‑rates are divided by the daily high‑speed allowance (before throttling). Delivery/return and deposits increase the effective rate. - eSIMs are sold in fixed data buckets (e.g., 5–20GB). You pay only for what you buy; topping up keeps costs predictable.Hidden costs pocket WiFi renters often miss: - Delivery and return fees (airport counters can be pricier; postage both ways adds up). - Deposits and loss/damage charges (commonly $100–$250 if lost; cases and cables also chargeable). - Fair‑use policies that throttle after a small high‑speed cap (throttled data is often too slow for maps/video). - Late return penalties if flights change.Pro tip: If you’re a couple using ~6–8GB each over a week in Europe, two eSIMs commonly beat one pocket WiFi on cost—and remove delivery/return hassle.Speed, latency and reliabilityBoth pocket WiFi and eSIM ultimately use the same local 4G/5G networks. Differences are mostly practical, not theoretical.Raw speed: Similar. Your phone with an eSIM can connect directly to 5G; many rental hotspots are 4G‑only or support fewer bands, which can limit peaks.Latency: eSIM is often 5–20 ms lower because there’s no extra WiFi hop and router processing. It’s noticeable on calls/gaming, not much for maps.Throttling: Pocket WiFi “unlimited” plans frequently throttle after a daily cap. eSIM plans throttle only after you use your purchased allowance (or not at all, depending on plan).Reliability: One fewer device means one fewer point of failure. With eSIM you avoid WiFi drops between your phone and a hotspot. Pocket WiFi can overheat or crash under many clients.Pro tip: If performance matters (video calls, hotspotting a laptop), prefer an eSIM plan that includes 5G where available and test speed in the first hour; top up if needed.Security and privacy on the roadeSIM on your phone:Uses cellular encryption end‑to‑end; no shared SSID.Fewer attack surfaces than carrying a router with a web admin panel.Your phone’s hotspot can be password‑protected with WPA2/3.Pocket WiFi:Safe if configured well, but risks include default/weak passwords, outdated firmware, and rogue admin access if not reset.Physical loss exposes stored SSID/passwords; some models display the password on the screen.Shared hotspots in groups increase chances of shoulder‑surfing or unauthorised joins.Security best practices: - Change the hotspot/router password immediately. Use WPA2/3 and a unique SSID. - Disable WPS and remote admin on pocket WiFi. - Keep device firmware updated (if you control the device). - Prefer your own eSIM hotspot over random public Wi‑Fi in cafés/airports.Multi‑device sharing: eSIM hotspot vs pocket WiFiYou can share eSIM data via your phone’s hotspot, often to 5–10 devices, subject to plan limits.eSIM hotspot advantages:No extra rental hardware; share instantly with your laptop, tablet, or a partner.Many travel eSIMs allow tethering; check the plan details before purchase.One SIM per person keeps usage fair and avoids a single point of failure.eSIM hotspot caveats:Tethering can drain your phone faster. Carry a 10,000–20,000 mAh power bank.Some carriers block or cap tethering; verify in the plan FAQ.Pocket WiFi advantages:Designed to share (commonly 8–15 devices).Keeps your phone free and reduces its battery drain.Pocket WiFi caveats:One shared connection means if the owner walks away, everyone loses internet.Extra device to charge and carry; range is limited (hotel rooms fine, large villas less so).Pro tip: For families, mix approaches—primary travellers each run an eSIM; turn on a hotspot only when the group needs it. This keeps speeds high and batteries happy.Practicalities: setup, pick‑up and returnsHow to install and activate a travel eSIM (step‑by‑step)Check compatibility and unlocked status in your phone settings.Buy a plan for your destination (e.g., Esim Western Europe, Esim North America, or browse Destinations).Receive your eSIM (QR code or manual code) by email.On Wi‑Fi, scan the QR or enter details to add the eSIM plan.Set the eSIM as “Mobile Data” and keep your primary SIM for calls (if desired).Turn on Data Roaming for the eSIM line.Optional: Set the APN if provided. Restart the phone.Test: open a webpage and a maps app. If slow, toggle airplane mode or reboot.Pro tips: - Install the day before you fly; activate only when you land if the plan timer starts on first connection. - Set a data warning in Settings at 80% of your allowance.How to use a pocket WiFi (checklist)Before trip:Order for the correct countries and dates; confirm daily high‑speed cap.Arrange delivery/pick‑up (airport counter hours, hotel delivery).Note deposit, loss/damage fees, and return process.On trip:Fully charge the hotspot each morning.Change SSID/password; disable WPS.Share the password securely with your group.Monitor LEDs/app for cap/throttle status.After trip:Return on time, in full kit (device, cable, charger, pouch) to avoid fees.Keep proof of return/shipping.Business and team travel: what scales best?For teams, the tipping point is management overhead. eSIMs scale neatly: issue plans per traveller, tag costs to projects, and avoid device logistics. Pocket WiFi can work for event booths or shared tablets, but devices go missing and shipping gets messy.Centralised purchasing and usage controls are easier with eSIM dashboards.

If no, lean pocket WiFi.Travelling solo or as a couple? eSIM usually wins on cost and simplicity.Need to share to 8–10 devices all day? Consider pocket WiFi (or carry a power bank for eSIM hotspot).Worried about deposits/returns? eSIM—nothing to ship or return.Crossing multiple countries? Choose a regional eSIM (e.g., Esim Western Europe or Esim North America).Security‑conscious? eSIM hotspot > public Wi‑Fi; avoid default router passwords.Regional notes and examplesUnited States: Coverage and speed vary by city and band support. Picking an eSIM that rides strong nationwide networks is key. Start with Esim United States.Western Europe: Competitive pricing and dense 5G make eSIMs excellent value. Multi‑country plans reduce SIM juggling. See Esim Western Europe.France, Italy, Spain: City and resort areas enjoy strong 4G/5G; eSIMs are typically the cheapest per GB. Compare Esim France, Esim Italy, and Esim Spain.North America: If you’ll cross into Canada or Mexico, a regional eSIM beats pocket WiFi roaming on cost and simplicity. See Esim North America.FAQIs eSIM as fast as a local physical SIM? Yes. eSIM is just a digital form of a SIM profile. Speeds depend on network coverage and plan, not the SIM form.Can I tether with an eSIM? Usually yes, but it depends on the plan. Most travel eSIMs allow hotspotting; check plan details. Some carriers cap tethering speeds or data.What if my phone is carrier‑locked? You may not be able to use a third‑party eSIM. Options: ask your carrier to unlock, use a pocket WiFi, or carry an unlocked secondary device for the eSIM.What happens when I run out of eSIM data? You either top up in‑app/online or buy another plan. Many travellers buy slightly more than needed to avoid mid‑trip disruption.Are “unlimited” pocket WiFi plans really unlimited? Typically not. Most have a daily high‑speed cap (e.g., 1–5GB) and then throttle severely. Check fair‑use policy specifics.Will a pocket WiFi work on flights or remote areas? It depends on terrestrial mobile coverage—just like your phone. No in‑flight cellular. In remote areas, neither option works well without coverage.Next step: Compare region‑ready travel eSIMs for your trip on Destinations.
