Barcelona Speed Test: BCN Airport, Sagrada Família, Gothic Quarter

This barcelona mobile speed test focuses on real traveller use: how fast your phone actually works at the airport, outside Sagrada Família, and in the Gothic Quarter during busy evening hours. We ran multiple passes between 18:00 and 21:00, when crowds spike and networks strain. The aim is to quantify crowd density sensitivity and offer practical steps to get dependable data for maps, ride‑hailing, streaming, and uploads.

We tested across the main Spanish networks with 5G/4G on modern iOS and Android devices using local eSIM and multi‑region plans. Results are presented in plain English with an open CSV so you can slice the data your way. If you’re heading to Catalonia, start with Destinations to plan coverage, then consider Esim Spain for simple set‑up on arrival. Multi‑country travellers can compare Esim Western Europe options too.

What we tested and why

  • Evening peaks: 18:00–21:00, when commuters, visitors, and events collide.
  • Crowd density: we tagged each pass as low/medium/heavy based on footfall and queue lengths.
  • Three high‑traffic spots:
  • BCN Airport (arrivals, baggage, landside cafés).
  • Sagrada Família (exterior plaza and queue areas).
  • Gothic Quarter (Plaça Reial/La Rambla side streets).
  • Metrics: download, upload, latency, jitter, signal (RSRP/RSRQ), radio tech (5G/4G), and SIM plan type.

Travellers care less about lab peaks and more about real, worst‑case behaviour—can you get a ride, upload a boarding pass, or stream HD directions in a crowd? This barcelona mobile speed test is designed for exactly that.

Methodology

Devices and SIMs

  • Handsets: recent iOS and Android flagships with 5G NSA/SA support.
  • Plans: local Spanish eSIM and multi‑region eSIMs.
  • Network mode: 5G preferred, fallback to 4G where necessary.
  • Settings: Fresh APN configuration, background updates paused, identical test sequences per pass.

If you need a local plan, consider Esim Spain. For onward trips, see Esim France and Esim Italy. North American travellers can preload plans via Esim North America or Esim United States.

Locations

  • BCN Airport: Terminal 1 Arrivals (near exits), baggage hall belts, and landside café seating.
  • Sagrada Família: main façade plaza, ticket queue area, side streets near metro exits.
  • Gothic Quarter: Plaça Reial, Carrer Ferran junctions, and La Rambla side alleys.

Time windows

  • Each site tested in three waves: approx. 18:15, 19:30, and 20:45.
  • Each wave included at least three full runs per device and plan.

Tools

  • Ookla Speedtest and nPerf for cross‑validation.
  • Ping, traceroute, and passive radio metrics (RSRP/RSRQ, SINR).
  • Manual crowd density tags.

Replicate this test: quick checklist

  • Update iOS/Android and carrier settings before flying.
  • Install your eSIM in advance; confirm APN after activation.
  • Lock to 5G Auto (not 5G On) to avoid unstable SA in fringe areas.
  • Run three back‑to‑back tests, discard obvious outliers, and note crowd levels.
  • For uploads, test at least a 100–200 MB file to see sustained behaviour.

Results at a glance

  • BCN Airport (Arrivals, evening): Reliable 5G/4G mix. Median downloads 85–160 Mbps; uploads 18–35 Mbps. Latency stable at 22–35 ms. Heavy baggage‑hall crowds shaved ~25% off throughput.
  • Sagrada Família (exterior plaza): Congested at golden hour. Median downloads 45–95 Mbps; uploads 8–22 Mbps. Latency 28–45 ms. Dense queues pushed a further 20–30% dip during group arrivals.
  • Gothic Quarter (Plaça Reial area): Narrow streets and heavy footfall. Median downloads 35–80 Mbps; uploads 10–20 Mbps. Latency 35–55 ms. Peak pub hours showed the sharpest drops, especially for uploads.

Headline: even in crowds, the airport stayed fastest; Sagrada and the Gothic Quarter were more sensitive to density and radio reflections.

Location deep dives

BCN Airport (T1 Arrivals and landside)

  • Coverage: Strong 5G NR near exits and landside cafés; occasional 4G fallback inside baggage halls.
  • Performance: Consistent. Evening crowds reduced speeds but rarely broke critical tasks (e.g., ride‑hailing, streaming maps).
  • Latency: Low and stable—great for VoIP and live translation.

Pro tips - If you need a hotspot for your group, start it landside, not inside baggage claim. - Download offline maps while waiting for bags; you’ll get the best throughput near exits. - If you’re on a multi‑region plan, toggle airplane mode once on the ground to refresh the roaming profile.

Sagrada Família (plaza and queues)

  • Coverage: 5G present but cell load high at sunset. Edges near metro exits sometimes flip to 4G with better uploads.
  • Performance: Download remains usable for HD navigation; uploads can stall during tour‑group surges.
  • Latency: Spikes coincide with event crowding; expect jitter during light shows or weekend evenings.

Pro tips - Move 30–50 metres away from the main façade queues for a cleaner signal and faster uploads. - If a big group arrives, wait 2–3 minutes and re‑run your upload—throughput often rebounds quickly. - Locking to 4G temporarily can smooth uploads if 5G is oversubscribed.

Gothic Quarter (Plaça Reial/La Rambla side streets)

  • Coverage: Plenty of small cells but tricky radio environment—narrow streets cause reflections and indoor penetration issues.
  • Performance: Good enough for messaging and browsing; large photo/video uploads slow down in the 20:00–22:00 window.
  • Latency: Higher variability. VoIP is fine; live streaming may need bitrate caps.

Pro tips - Step into an open square (Plaça Reial or near the cathedral) to escape canyon effects before uploading. - Keep a secondary plan active as backup if you must post live—multi‑profile eSIMs can fail over faster. - Avoid peak pub hours for big cloud backups; schedule them after 23:00 or the following morning.

Crowd density sensitivity

Evening crowding mattered more than raw signal strength. In multiple passes:

  • Heavy vs. low crowding reduced median downloads by 20–35% at Sagrada and the Gothic Quarter.
  • Uploads were more fragile—drops of 30–50% occurred during tour‑bus arrivals or live events.
  • Latency rose by 8–15 ms on average under heavy density, with jitter doubling briefly.

What this means for you - Time‑shift large uploads (photos, videos, backups) to off‑peak times. - For ride‑hailing at Sagrada, place your pin, then wait 10–20 seconds for data to settle before confirming. - Enable “Upload on Wi‑Fi only” for cloud galleries while in the Gothic Quarter’s busiest lanes.

The dataset (open CSV)

Below is a condensed, open CSV excerpt you can copy into your tool of choice. Columns: timestamp (local), location, crowd, radio, download_mbps, upload_mbps, latency_ms, network_note.

How to reuse - Filter by location to compare evening waves. - Graph crowd vs. upload_mbps to see sensitivity. - Compare 5G vs. 4G rows per site to decide when to force 4G for stability.

Practical recommendations

Before you fly

  • Install your eSIM and test data locally. For Spain, start with Esim Spain.
  • Planning a multi‑city loop? A regional pass such as Esim Western Europe can reduce roaming quirks between borders.
  • Coming from North America? Preload via Esim North America or Esim United States to avoid airport Wi‑Fi set‑up hassles.
  • Save offline maps for Barcelona and Catalonia.

On the day

  • At BCN Airport, finish big downloads landside. Toggle airplane mode once to refresh roaming.
  • Near Sagrada, step away from the main façade for steadier uploads; retry after tour‑bus surges.
  • In the Gothic Quarter, move to an open plaza for better 5G; cap live‑stream bitrates if needed.
  • If 5G feels choppy, switch to 4G for a few minutes—uploads often improve under load.

For teams and frequent travellers

  • Business cohorts should consider pooled data and centralised controls via For Business.
  • Travel providers and resellers can streamline activations through the Partner Hub.

FAQs

1) What speeds can I realistically expect in the evening? - At the airport, 85–160 Mbps down and 18–35 Mbps up are typical. Sagrada and the Gothic Quarter trend lower—35–95 Mbps down and 8–22 Mbps up—depending on crowd density.

2) Is 5G always better than 4G in Barcelona? - Not always during heavy load. 5G can deliver higher peaks, but when cells are saturated, 4G may provide steadier uploads. If uploads stall on 5G, try a temporary 4G lock.

3) What’s the best time for large uploads? - Outside peak windows. After 21:30, both Sagrada and the Gothic Quarter recover noticeably. Early morning also works well.

4) Do I need a local eSIM or will roaming suffice? - Either works. A local plan like Esim Spain usually yields the most predictable performance. If you’re touring multiple countries, Esim Western Europe can be more convenient.

5) I’m arriving from the US—should I set up before departure? - Yes. Install and activate your plan (e.g., Esim United States for your outbound leg or Esim North America if you’ll return via Canada/Mexico), then add your Spanish profile so it auto‑switches on landing.

6) I’m continuing to France and Italy—will my plan work there? - Many regional plans do. Check your inclusions; if not covered, add Esim France or Esim Italy before you go to avoid setup on busy streets.

Summary

  • Evening crowds in Barcelona meaningfully impact mobile performance—uploads suffer most around Sagrada and in the Gothic Quarter.
  • The airport remains dependable for essential tasks; use landside time to sync and download.
  • 5G is great when uncongested; under load, a brief switch to 4G can stabilise uploads.
  • Use the open CSV to plan your own workflows and time‑shift heavy uploads to off‑peak.

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.

Coverage Expansion: 5G in Key Tourist Cities (Q4 2025)

Coverage Expansion: 5G in Key Tourist Cities (Q4 2025)

Simology’s Q4 update brings wider, faster 5G to the places travellers actually go. This simology 5g coverage expansion focuses on key tourist cities across North America and Western Europe, boosting peak and average speeds, improving indoor reach, and smoothing handoffs between busy cells. Whether you’re streaming maps, uploading reels, or tethering a laptop, you should feel the difference in airports, old towns, stadiums, and along major transit corridors. Expected real‑world speeds typically range from 100–600 Mbps on mid‑band (n77/n78) with bursts above 1 Gbps in favourable spots. As always, results depend on device support, local spectrum, and network congestion.Below you’ll find the city lists now covered on our 5G partner footprints, what speeds to expect, device band notes (so you can check compatibility before you buy), and quick steps to get set up. We’ve added practical checklists and pro tips, plus links to our eSIMs by region so you can pick the right plan. If you care about the numbers, we regularly publish real‑world results in our Speed Tests category and will keep updating as new cells light up.Where 5G just got faster: key tourist cities (Q4 2025)We’ve expanded 5G access on our partner networks across high‑traffic destinations. Coverage and speed are strongest in dense urban cores and around landmarks, with improving indoor penetration on mid‑band.United States highlightsGood news if you’re heading to the US—expect stronger mid‑band and more consistent 5G in:New York City (Manhattan, Brooklyn waterfronts, Midtown transit hubs)Boston, Washington DC, PhiladelphiaMiami, Orlando, TampaChicago, Detroit, MinneapolisLas Vegas, Phoenix, DenverLos Angeles, San Diego, San Francisco Bay AreaSeattle, PortlandHonolulu tourist corridorsTypical experience: - Mid‑band 5G (n41/n77): 200–600 Mbps; lower latency vs 4G. - mmWave (n260/n261) pockets in dense zones: 1–3 Gbps bursts at short range. - Sub‑6 indoor coverage improving in malls, convention centres and airports.Planning US travel? Compare regional options via Esim United States or bundle routes with Esim North America.France highlightsUrban 3.5 GHz coverage (n78) continues to mature across:Paris (central arrondissements, business districts, key RER/Metro interchanges)Nice, Cannes, MarseilleLyon, Toulouse, BordeauxLille, Strasbourg, NantesTypical experience: - n78 mid‑band: 150–500 Mbps, often higher outdoors. - n1/n3 anchors assist indoor coverage; expect 5G to hold in large stations and shopping areas.See plans for city breaks and TGV routes via Esim France.Italy highlightsTourist corridors and historic centres see broader 5G overlays in:Rome (Termini area, Trastevere edges, Vatican surrounds)Milan (Duomo, Navigli, business districts)Florence, Venice, Naples, BolognaTurin, Verona, PalermoTypical experience: - n78 mid‑band in city centres: 150–450 Mbps. - n1/n3/n7 support improves handoffs; dense stone architecture can still limit indoor reach—step near windows for best results.Plan your itinerary with Esim Italy.Spain highlightsStrong city coverage and coastal hotspots in:Barcelona (Eixample, Gothic Quarter edges, Sants)Madrid (Sol, Castellana, Atocha, Chamartín)Valencia, Seville, Málaga, BilbaoBalearic tourist zones see seasonal boostsTypical experience: - n78 mid‑band: 150–500 Mbps. - Stadiums and transport hubs may throttle at peak; off‑peak is significantly faster.Compare Spanish coverage with Esim Spain.Western Europe multi‑countryIf your trip spans multiple countries, our regional profile is the simplest way to roam on 5G with one eSIM:Common city pairs: Paris–London–Brussels, Milan–Zurich, Barcelona–Nice, Amsterdam–Berlin corridorsStrongest in major capitals and intercity rail hubsTypical experience: - n78 mid‑band where available: 150–500 Mbps - Fallback to LTE‑Advanced where 5G is thin; you’ll still see lower latency vs legacy roaming.Browse itineraries on Esim Western Europe and explore more city guides via Destinations.Expected speeds and what affects themOutdoors on mid‑band (n77/n78): 200–600 Mbps is common in North America and Western Europe urban cores.Indoors: 80–250 Mbps depending on building materials and proximity to windows.Busy events: 5G may still outperform 4G, but congestion and deprioritisation can mute speeds. Try side streets or step outside large venues.mmWave in the US: Great for short, line‑of‑sight bursts near stadiums, squares and certain transit hubs. Expect 1–3 Gbps, but coverage is highly localised and falls back quickly.Remember: your device’s supported bands and firmware matter as much as the local tower.Device band notes (check before you fly)Most recent flagship devices support the right mix of bands, but it’s worth verifying to maximise 5G.United StatesKey bands: n5 (850), n41 (2.5), n66 (AWS), n77 (C‑Band), n260/n261 (mmWave)iPhone 12 and newer: strong Sub‑6; US models also support mmWave.Pixel 6 and newer; Galaxy S21 and newer: good mid‑band; mmWave support varies by model/region.France/Italy/Spain/Western EuropeKey bands: n1 (2100), n3 (1800), n7 (2600), n28 (700), n78 (3.5 GHz)iPhone 12 and newer: excellent n78 support.Pixel 5 and newer; Galaxy S20 and newer: typically support n78 plus low/mid anchors.Tips: - Imported phones may lack local bands. Double‑check your exact model number. - Dual‑SIM: set your Simology line as “Primary” for data and enable 5G Auto/5G On. - Keep device software up to date to ensure the latest carrier settings.How to get 5G on Simology (step‑by‑step)Pick your plan - Single‑country or regional: try Esim United States, Esim France, Esim Italy, Esim Spain, or Esim Western Europe. Multi‑country travellers should consider Esim North America or Western Europe for seamless roaming.Install your eSIM - Scan the QR code or use activation codes in your order email. Keep Wi‑Fi on during install.Set Simology as your data line - On iOS: Settings > Mobile Data > Default Voice Line/Data > choose your Simology eSIM. Turn on 5G Auto/5G On. - On Android: Settings > Network & Internet > SIMs > turn on Mobile data for Simology. Select 5G preferred.Check APN if prompted - Most profiles auto‑configure. If needed, follow the APN values in your confirmation email.Restart and test - Give your phone 30–60 seconds on reboot to register on 5G. Run a quick speed test near a window or outdoors.Before‑you‑fly checklistConfirm your phone’s 5G band support for your destination.Update iOS/Android and carrier settings.Turn off Low Data Mode/Data Saver for best performance.Enable VoLTE/Wi‑Fi Calling for reliable voice (when available).Download offline maps just in case indoor coverage is patchy.Bring a small power bank; 5G can use more battery in weak‑signal zones.Pro tips to maximise speed and stabilityMove 5–10 metres: stepping outside or towards a window can double your throughput.Avoid crowd hotspots during events; a nearby side street may give better quality.Toggle Airplane Mode for 5–10 seconds if you lose 5G after leaving the metro or a tunnel.Prefer mid‑band: if your phone shows “5G” but feels slow, you may be on a low‑band 5G NR carrier layer. A quick cell reselection (Airplane Mode toggle) can lock you onto faster mid‑band.Tethering: use the 5 GHz hotspot band for cleaner spectrum, especially in apartment blocks and hotels.Numbers nerd? Check our Speed Tests category for live results and city‑by‑city notes.For teams and partnersBusiness travel managers: consolidate connectivity across regions with pooled data and central billing via For Business. We can pre‑stage eSIMs for conferences and seasonal deployments.Travel partners and resellers: integrate our regional plans and city‑level coverage updates through the Partner Hub.How we measure performanceWe combine crowd‑sourced session analytics (latency, throughput, packet loss) with in‑city walk tests near airports, major stations, popular attractions and conference venues. We prioritise real‑world traveller routes over lab peaks. You’ll see the methodology and raw screenshots in our Speed Tests posts. Expect ongoing updates as new spectrum is lit, additional small cells come online, and stadiums add capacity.FAQsWill I get 5G everywhere in these cities?No network offers 100% 5G. Expect strong mid‑band in central areas and along major transport, with occasional fallbacks to LTE indoors or in narrow streets. Our profiles roam across partner networks to keep you on the best available layer.Do I need a specific phone model for this update?Any 5G‑capable, eSIM‑compatible device with the right bands will benefit. iPhone 12+/Pixel 5+/modern Galaxy flagships are safe bets. Check your exact model’s band list against the notes above.Can I use mmWave in the US?In select dense spots, yes—if your device supports n260/n261 (US‑sold iPhones and certain Androids). mmWave coverage is hyper‑local; think stadium plazas and parts of downtown blocks. Most of your day‑to‑day will be fast Sub‑6 mid‑band.How do I check coverage for my itinerary?Start with our regional plan pages (Esim United States, Esim France, Esim Italy, Esim Spain, Esim Western Europe, Esim North America) and city notes on Destinations. We also post recent real‑world numbers in our Speed Tests articles.Is tethering allowed on Simology 5G plans?Yes on most plans, within fair‑use limits. Performance depends on your device radio and signal quality. Use the 5 GHz hotspot band for best results and keep the phone near a window for steadier mid‑band.What if speeds feel slow?Try: move a few metres, toggle Airplane Mode, ensure 5G Auto/Preferred is on, switch off Low Data Mode/Data Saver, and check for pending OS/carrier updates. If issues persist, contact support with your device model, location and a screenshot of your network status.What this means for your next tripIn short: you’ll see faster uploads and more consistent streaming in the places visitors actually spend time—downtowns, transport hubs, and major sights—across the US, France, Italy, Spain, and wider Western Europe. If you travel for work, pooled data and easy provisioning via For Business make multi‑city trips simpler. If you’re a partner, the Partner Hub has rollout notes and assets.Next step: browse city‑by‑city options and pick the right eSIM for your route on Destinations.

Coverage Metrics Decoded: RSRP, RSRQ, SINR in Plain English

Coverage Metrics Decoded: RSRP, RSRQ, SINR in Plain English

A full set of signal bars doesn’t always mean fast data, and a single bar doesn’t always mean you’re stranded. The real story sits behind the scenes in three radio metrics used by 4G LTE and 5G: RSRP, RSRQ and SINR. If you’re a traveller juggling maps, ride‑hailing, translation, streaming, or hotspot sharing, these numbers can tell you whether moving closer to a window, switching to LTE, or trying a different network will help. This guide goes beyond jargon to give you rsrp rsrq sinr explained in plain English, including practical thresholds for “good/OK/poor”, how buildings and city streets skew each value, and quick steps to read them on iPhone and Android. We’ll also show how to act on what you see—useful if you’re bouncing between countries in Esim Western Europe, the Esim United States, or wider Esim North America.RSRP, RSRQ, SINR explained (really simply)RSRP (Reference Signal Received Power): Think “how loud is the tower’s voice at your phone”. It’s pure signal strength from the cell, measured in dBm (negative numbers; closer to zero is stronger).RSRQ (Reference Signal Received Quality): Think “how clearly you can hear that voice in a crowd”. It mixes strength with how busy the channel is, measured in dB (negative numbers; closer to zero is better).SINR (Signal to Interference plus Noise Ratio): Think “signal versus all the junk around it”. A higher positive number is cleaner. This drives your top speeds and stability.Used together: - RSRP tells you if you’re near/far or shielded by walls. - RSRQ and SINR tell you if interference, reflections, or congestion are ruining quality.Units and signs at a glanceRSRP: dBm, typically −65 (excellent) to −120 (very poor). Less negative is better.RSRQ: dB, typically −3 (excellent) to −20 (very poor). Closer to 0 is better.SINR: dB, typically −10 (unusable) to 30 (excellent). Higher positive is better.What counts as good, OK, or poor?These are practical, field‑tested thresholds for everyday travellers on 4G LTE and sub‑6 GHz 5G. mmWave behaves differently and is extremely sensitive to blockage.RSRP (signal strength)Excellent: −80 dBm or strongerGood: −80 to −90 dBmFair/OK: −90 to −100 dBmPoor: −100 to −110 dBmUnreliable: weaker than −110 dBmRSRQ (signal quality)Excellent: better than −10 dB (e.g., −3 to −9)Good: −10 to −12 dBFair/OK: −12 to −15 dBPoor: worse than −15 dBSINR (clean signal vs. junk)Excellent: > 20 dBGood: 13–20 dBFair/OK: 0–13 dBPoor: < 0 dBQuick mental model: - High RSRP + high SINR = best speeds and stability - High RSRP + low SINR/RSRQ = close to a cell but lots of interference/congestion - Low RSRP + decent SINR/RSRQ = further away; may be stable but slowerPro tip: When speeds are the goal (video calls, uploads), SINR is the star metric. RSRP is necessary, but SINR unlocks higher modulation and throughput.How buildings and streets change the numbersWhy your metrics change from street to lobby to lift:Walls and windows reduce RSRP (strength)Typical losses: modern glass 2–10 dB; brick 10–20 dB; reinforced concrete 20–40 dB; metal/low‑E coated glass up to 30+ dB.Sub‑6 GHz 5G and 4G at lower bands (700–900 MHz) penetrate better than higher bands (1800–3500 MHz).Urban “canyons” hurt SINR and RSRQ (quality)Reflections from glass and metal create multipath. Your phone hears the same signal arriving slightly out of sync, increasing interference.You may see decent RSRP but poor SINR/RSRQ on busy downtown corners.Elevation helps—sometimesHigher floors near a window often improve RSRP and SINR by clearing street‑level clutter.Deep inside high‑rise cores or basements, both RSRP and SINR usually drop.5G specificsSub‑6 GHz 5G (most of Europe and many US deployments) behaves like 4G but usually offers more capacity.mmWave 5G (pockets of the Esim United States) is extremely fast outdoors, but a single wall or even your hand can drop RSRP and SINR to unusable.How to see RSRP/RSRQ/SINR on your phoneNot every phone/carrier exposes every value. Try these:iPhone (Field Test Mode)Make sure mobile data is on and you have reception.Dial 3001#12345# and press call. This opens Field Test Mode.Look for menus labelled “LTE” or “NR-NSA/NR” (5G Non‑Standalone).Find entries called RSRP, RSRQ, and SINR (sometimes “RS-SINR”).If you can’t find them, back out and explore “All Metrics” or “Serving Cell Meas”. Availability varies by iOS version and network.Pro tip: If you’re on 5G NSA, measurements may appear under LTE (for control) and under NR for 5G data. Check both.Android (varies by brand)Pixel (and many stock Android phones): 1. Settings > About phone > SIM status. 2. Look for “Signal strength” (dBm). Some builds also show RSRP/RSRQ; others show RSSI/ASU only.Samsung: 1. Settings > About phone > Status information > SIM card status for signal strength. 2. Advanced readouts may be available via ServiceMode codes like *#0011# (not guaranteed; depends on carrier/region).If native menus don’t show RSRP/RSRQ/SINR, reputable network diagnostic apps can help. Install before you travel.Accuracy tips: - Readings refresh as you move; give them 10–20 seconds after relocating. - Hold the phone naturally—don’t cover the top edge or antenna bands.Make sense of the trio: common scenariosStrong RSRP, poor SINR/RSRQYou’re near a cell or indoors with strong reflections. Expect inconsistent speeds, buffering, or call drops in crowds.Try: move a few metres, face a window, or step outside. For stability, temporarily switch to LTE if 5G is flapping.Weak RSRP, decent SINRRural edge or deep indoors. You may get steady but moderate speeds—fine for maps and messaging.Try: higher floor, near a window, or a different room. Low‑band cells travel further; your phone may prefer LTE in these spots.Good metrics but slow speedsNetwork congestion. Quality is fine; capacity is saturated (stadium, rush hour).Try: force a different band/tech (LTE vs 5G), reselect the cell (Airplane Mode toggle), or switch network via a local eSIM.Traveller checklist: quick wins to improve your metricsMove three ways before anything else: 2–5 metres, nearer a window, or up/down one floor.Place your phone on a window ledge or table rather than in your pocket or bag.Toggle Airplane Mode for 10 seconds to reselect a potentially better cell.If 5G is unstable indoors, try LTE temporarily; if LTE is congested, try 5G where available.Turn on Wi‑Fi Calling for voice if data is OK but calls drop.Hotspot positioning: put the hotspot/phone by the best‑signal window; connect your laptop from inside.Consider a local or multi‑network eSIM so you can switch to whichever carrier gives better SINR/RSRQ in your area:Touring several countries? See Esim Western Europe.City‑hopping across the US and Canada? Check Esim North America and the country‑specific Esim United States.Planning Paris, Rome or Barcelona? Compare Esim France, Esim Italy and Esim Spain.Travelling as a team? Centralise connectivity choices with For Business.Pro tips for faster, steadier dataPrioritise SINR for throughput. A jump from 8 dB to 18 dB can boost real‑world speeds dramatically, even if RSRP hardly changes.Low bands (700/800/900 MHz) penetrate buildings best; mid bands (1800/2100/2600/3500 MHz) are faster but need clearer paths. Indoors, aim for the lowest‑band cell you can catch reliably.If your phone or hotspot supports it, enabling LTE/5G carrier aggregation and keeping battery above 20% can maintain higher‑order modulation under marginal SINR.Roaming doesn’t inherently worsen radio metrics; it’s about which network you’re on. Having multiple profiles lets you pick the cleanest signal locally via Destinations.Partners and travel providers: help your guests connect first time by sharing these thresholds and stocking multi‑region eSIMs via our Partner Hub.FAQWhat is a “good” RSRP for 5G?Aim for −80 to −90 dBm for consistently fast 5G. 5G can still work down to around −100 dBm, but speeds and stability depend heavily on SINR and band.Which metric matters most for speed: RSRP, RSRQ or SINR?SINR. It reflects how clean the signal is and determines the modulation your phone can use. RSRP provides the foundation; RSRQ hints at network loading and interference.Why do I have 4 bars but slow data?Bars often reflect signal strength (RSRP) but not quality (SINR/RSRQ) or cell congestion. Good strength plus poor quality or heavy load = slow.Is RSSI the same as RSRP?No. RSSI is a broader received power measurement including noise and interference. RSRP isolates the reference signal and is the standard metric for LTE/5G coverage assessments.Do buildings affect 4G and 5G differently?Yes. Both are attenuated by walls, but higher‑frequency 5G bands lose more signal indoors. mmWave 5G struggles through most materials; sub‑6 GHz 5G behaves more like 4G.Will switching to LTE help if 5G is flaky indoors?Often, yes. LTE on a lower band can deliver steadier SINR indoors, even if peak speeds are lower. Try LTE for calls and uploads; switch back to 5G outside for capacity.The bottom lineUse RSRP to judge if you have enough raw signal, RSRQ to sense network cleanliness, and SINR to predict real speeds. Small moves (window, floor, angle) can add 5–20 dB where it matters. When a network’s quality is poor where you are, the fastest fix is often switching to a different carrier via an eSIM with regional coverage.Next step: Compare country and regional options on Destinations.
