5G Tower Coverage Maps Worldwide: Where to Find Them

Traveler checking a mobile coverage map

No single map shows every 5G tower in the world. The practical approach is to combine three kinds of maps: operator coverage maps, crowdsourced signal maps and tower databases. GSMA, nPerf, CoverageMap, CellMapper, LastBar and Sogudo each cover a different part of the picture. This guide explains what each one shows, how current it is, and how to turn a map into a decision about the eSIM to buy for a trip.

Once you’ve checked 5G coverage for your destination, explore prepaid data eSIMs for 170+ countries from eSIMGlobe.

TL;DR

  • Operator-based maps show promised coverage. Crowdsourced maps show where phones actually found a signal. Tower maps show infrastructure, not signal quality.
  • nPerf, CoverageMap, LastBar and Sogudo are the quickest ways to check a destination country by country.
  • A map showing 5G does not guarantee 5G on a phone. The phone, the plan and the network must all support it, and some mapped areas are only operator test zones.
  • Check the city and the neighborhoods where the trip happens, not the national average.
  • eSIMGlobe sells prepaid data eSIMs for 170+ countries, so the network check can be followed by a plan in minutes.

The three kinds of 5G maps

Maps sold under the label “5G coverage” answer three different questions. Mixing them up is the most common reason a traveler is surprised on arrival.

Map type Question it answers Typical data source Main weakness
Operator coverage map Where does the carrier say it has service? Data supplied by the carrier Shows promised coverage, not measured experience
Crowdsourced signal map Where did real phones connect? Speed tests and signal readings from app users Thin in places few users visit
Tower map Where are the masts? Public and community tower databases Shows a site, not signal strength or 5G activation

The sections below place each well-known map in one of these groups.

Operator-sourced global maps

GSMA coverage data

The GSMA publishes a global mobile network coverage dataset that comes directly from operators worldwide and is updated by GSMA members. It is offered as a global raster (GeoTIFF) plus historical vector datasets. This is built for analysts and planners, not for a quick street-level check on a phone. It is useful when you want to know whether a whole region has any network coverage at all.

Collins Bartholomew

Collins Bartholomew has produced an annual mobile network coverage data product every year since 2010. Its technical notes say the 2024 Mobile Coverage Explorer release contains operator data received up to the end of 2023. That is a reminder that any operator-based dataset is a snapshot, and 5G rollouts move faster than annual releases.

The same technical notes list the limits of this kind of map. Data may not account for terrain, and measurements can be concentrated along routes and built-up areas. Where operator maps are incomplete, the product supplements them with OpenCelliD tower data, which is an approximation that does not account for terrain obstacles.

Crowdsourced maps: where phones actually connected

Crowdsourced maps are the closest to a traveler’s reality, because they record what handsets experienced.

nPerf

The nPerf 5G map is built from tests run by app users in real-world conditions. According to its own description, coverage maps are updated hourly and speed maps every 15 minutes. It filters data for publication: coverage tests keep a maximum geolocation precision of 50 meters, and download bitrate tests keep 200 meters. It also warns that some mapped zones show 5G detected during operator technical testing, which are not necessarily open to customers.

CoverageMap

CoverageMap processes crowdsourced speed test and signal strength measurements from its app users. It gives a view of cellular networks across more than 30 countries. It is a good fit for a trip to a mainstream destination, and less so for remote regions.

LastBar

LastBar maps signals contributed by users in about 50 countries. It states the idea plainly: show the coverage phones found, not the coverage carriers promise. In areas where no user has traveled yet, it estimates where towers are and labels that as an estimate. For trips that leave the main roads, that distinction matters.

Sogudo

Sogudo maps 4G and 5G in more than 100 countries and regenerates its maps monthly from public antenna data and crowdsourced measurements. That makes it the widest country list among the consumer-friendly tools in this guide.

Tower maps

CellMapper is a cellular tower and signal map. Users can filter by 5G ENDC-capable towers, bands, frequencies and verified status. Those filters are what make it useful: a tower listed on a map is not the same as a tower broadcasting 5G on the band your phone supports.

Apps built on large tower databases exist as well. One of them states that its database covers 45 million towers worldwide across 2G, 3G, 4G and 5G, aggregated from public and community-sourced data. A tower count is helpful for locating infrastructure, but it says little about speed in a crowded station at 6 p.m.

How to check a destination step by step

The sequence below takes about ten minutes and works for any country on the maps above.

  1. Pick the destination city and the areas where you will spend time. Hotel district, airport, business district, the route between them.
  2. Open a country page on a map with carrier filters. On Sogudo, a traveler can open a country page, select a mapped carrier, switch between 4G and 5G, and search an address to see expected street-level signal strength.
  3. Cross-check against a crowdsourced map. Compare the carrier map with nPerf or CoverageMap for the same neighborhood. If the operator map shows solid 5G and measured data is empty, treat the 5G as unconfirmed.
  4. Look at the tower layer for remote stops. For hiking, coastal roads or rural stays, a tower map shows whether any mast exists nearby.
  5. Confirm the phone. Check that the handset supports 5G and eSIM, and that it is unlocked.
  6. Choose the plan after the check, not before. Match the plan to the country or region where you confirmed a usable signal.

Why a phone shows 4G where the map shows 5G

There are four common causes.

The mapped area is a test zone. nPerf notes that its map can show places where 5G was detected during technical operator testing, not necessarily commercially open.

The phone or SIM does not support 5G. The same page points out that both the phone and the SIM must be 5G-compatible. A phone sold for a single market can lack bands used elsewhere, and a plan can cap the network type.

The map is older than the network. Annual datasets lag. Hourly and monthly sources are better for places where operators are still building.

The signal is 5G in name only. Low-band 5G can reach far but deliver speeds closer to LTE, and a tower with 5G on a map does not say which band it uses. For the practical difference between 5G types, see our guide to what 5G eSIM coverage actually delivers for travelers.

Reading the limits of any worldwide map

Some limits apply to every map in this guide.

  • Data density varies. Measurements cluster along routes and in built-up areas, and in countries where the measuring app is popular. A blank spot may mean no one has tested there, not that no signal exists.
  • Terrain is hard to model. Interpolated tower coverage ignores hills, valleys and buildings.
  • Precision is limited. App tests depend on GPS accuracy, and nPerf filters tests accordingly.
  • Maps compare carriers, not countries. A country can have strong 5G on one network and none on another. Compare the network your eSIM uses, not the national headline.
  • Indoor signal is not mapped well. Basements, trains and airports often perform differently from street-level readings.

A fair reading is to treat any single map as a hint and two agreeing maps as a decent forecast.

Local carriers and what they tell you

When a country has several networks, it helps to know the names. In the United States, Verizon, T-Mobile and AT&T publish their own coverage maps. In the United Kingdom, EE, Vodafone, Three and O2 do the same. In Japan, NTT Docomo, au (KDDI), SoftBank and Rakuten Mobile are the main names, and in Canada they are Rogers, Bell and Telus.

These carrier maps are written to sell local subscriptions. They are a good starting point for knowing which networks exist, but they usually assume a resident with a local plan. A visitor on a foreign SIM can face a different situation: a roaming plan from a home carrier may carry a travel add-on cost, and speeds depend on the partner network. A prepaid travel eSIM sidesteps that by being sold for the destination from the start. For a worked comparison of one such case, read how eSIMGlobe compares with Vodafone’s travel eSIM.

Local carriers and what they tell you

What to do when the maps show no 5G

Not every trip lands in a 5G area. If the maps show only 4G, the plan is still workable.

  • Choose a plan with 4G/LTE support so the phone falls back cleanly.
  • Download offline maps and key documents before leaving the city.
  • Keep Wi-Fi for large downloads and use mobile data for navigation, rides and messaging. The trade-off is covered in hotel Wi-Fi versus eSIM.
  • For rural regions, check the tower layer on CellMapper or LastBar before the trip and note where signal gaps are likely.

For road trips in the US, three checks to verify a USA eSIM coverage map lay out a similar routine in more detail.

Perspective

Coverage maps answer where a signal can exist. A traveler needs to know whether a plan will work at the arrival gate, in the hotel and on the way to the first meeting.

That is why we treat the map as step one and the plan as step two. A traveler who confirms a network in the destination city should be able to buy a prepaid data eSIM, receive it by email and install it with a QR code. Our claim is delivery in under 30 seconds, with support available 24/7 if something goes wrong at that moment.

We sell data-only plans for 170+ countries, with country plans, regional plans and unlimited options, priced one-off with no subscription. We also offer a money-back guarantee if the network fails. For a trip that crosses borders, a regional plan removes the need to repeat the map check and the purchase at each stop.

Our advice: use two maps, pick the city, then choose the plan that matches the route.

Matching the map result to an eSIM

The map check should end in one of three decisions.

One country, one trip. Buy a country plan. Published starting prices include Thailand from $2.50, the United States from $2.50, the United Kingdom from $2.90, Spain from $3.20, China from $3.50, Italy from $3.90 and Brazil from $4.00, all one-off, with the final price depending on the data amount and duration selected at checkout.

Several countries in one region. Buy a regional plan. Europe (30+ areas) starts from $2.60, and Asia (7 areas) from $3.60. For South America and the Caribbean, see the South America collection, with plans from $8.70 and $9.00 respectively.

Heavy use or remote work. Consider an unlimited plan. The unlimited plans collection lists Japan from $5.50, Thailand from $5.00, Europe (30+ areas) from $8.20, North America from $10.30 and India from $10.00. People who work from the road may also find the guide to the best eSIM for digital nomads useful.

For routes that touch many continents, a global plan covers more than 120 areas in one profile: see eSIM Global (130+ areas) or eSIM Global (120+ areas).

Get the plan after the map check

The map tells you whether a network is worth using. eSIMGlobe delivers the plan by email after online checkout, with no physical SIM and no roaming bill. Plans are data-only, prepaid and pay-per-use, with 5G/4G LTE support on partner networks, secure payment and telecom-grade encryption.

Choose the destination on the eSIMGlobe homepage, compare the country or regional plan, and install it before departure.

eSIM Global (130+ areas)

For Europe, the Europe (40+ areas) plan covers a wider country list than the 30+ area version, which suits multi-country rail trips.

Compatibility checklist before buying

A correct map reading still fails on an incompatible phone. Check these items.

  • eSIM support. The phone must support eSIM. Most recent flagship phones do, but check the settings menu or the manufacturer’s specification page.
  • 5G support. The phone must support 5G, and ideally the bands used at the destination.
  • Unlocked status. A carrier-locked phone can refuse a new eSIM profile.
  • Free eSIM slot. Phones store a limited number of eSIM profiles. Delete old ones if the list is full.
  • Data roaming setting. Turn on data roaming for the travel eSIM line only, and keep the home line’s data off to avoid unplanned charges.
  • Install timing. Install the profile while on Wi-Fi before departure, then switch it on at arrival.

FAQ

Is there one map that shows all 5G towers worldwide?

No. Operator datasets such as GSMA’s are built for analysis, crowdsourced maps such as nPerf, CoverageMap and LastBar cover a limited number of countries, and tower databases show masts without confirming 5G. Using two of them for the same city gives the most reliable picture.

How current are worldwide 5G maps?

It depends on the source. nPerf says coverage maps update hourly and speed maps every 15 minutes, while Sogudo regenerates its maps monthly. Operator-based products can be older: the Collins Bartholomew 2024 dataset includes operator data through the end of 2023.

Why does my phone show 4G when the map shows 5G?

The mapped zone may be an operator test area that is not open to customers. The phone or the SIM may also lack 5G support. A third cause is outdated map data, so check a second map for the same street.

Can I use a coverage map to pick between carriers in another country?

Yes, with limits. Sogudo lets you choose a carrier on a country page, switch between 4G and 5G and search an address. For a travel eSIM, the plan’s network partner matters more than the national leader, so check the plan details before paying.

Do I need 5G for a short trip?

Usually not. Maps, rides, messaging and video calls run well on 4G/LTE. A 5G-capable plan is a bonus where the network exists and a safe fallback to 4G where it does not.
