Best cell phone coverage at my address

The mobile and broadband checker lets you:

• check indoor/outdoor mobile availability for voice and data services from all major operators, as well as outdoor availability of 5G services
• view broadband availability and speeds for any UK address
• get tips on how to improve your internet connection or mobile coverage.

Enter a postcode to view mobile coverage by provider, or availability of broadband services (standard, superfast and ultrafast). You can also view the results as interactive maps.

If you can’t get a download speed of 10Mbit/s, you may be eligible for the broadband Universal Service Obligation (USO).

What the Map Shows

This map shows the 4G LTE mobile coverage areas of the nation’s four largest mobile wireless carriers: AT&T Mobility, T-Mobile, UScellular, and Verizon. Specifically, it shows where customers can expect to receive 4G LTE broadband service at a minimum user download speed of five megabits per second (5 Mbps) and a user upload speed of one megabit per second (1 Mbps) based on propagation modeling.

The map includes separate layers for each carrier’s broadband and voice coverage. Voice coverage areas represent where customers should expect to make and receive mobile voice calls and send and receive texts over the 4G LTE network, without regard to throughput speed. 4G LTE data service meeting a 5/1 Mbps minimum speed may not be available in areas where only voice coverage is shown on the map.

How to Use the Map

Consumers can enter in specific addresses or zoom in to locations to see where 4G LTE mobile data and voice service is available. Users can choose to view providers’ mobile data and/or voice service by clicking on a provider’s data or voice service layer.

How the Map was Prepared

The coverage map was created using data submitted voluntarily by the four mobile carriers using certain standardized propagation model assumptions or parameters that were established by the FCC as part of the Broadband Data Collection. These standard parameters are intended to create a more uniform and consistent comparison of coverage among service providers than has previously been available through the FCC’s Form 477 process. Because of this, this map is the first ever standardized look at 4G LTE mobile data and voice service availability.

Please note: The map depicts the coverage a customer can expect to receive when outdoors and stationary. It is not meant to reflect where service is available when a user is indoors or in a moving vehicle.

Because the coverage map is based on propagation modeling, a user’s actual, on-the-ground experience may vary due to factors such as the end-user device used to connect to the network, cell site capacity, and terrain.

The coverage maps on these service providers’ websites may be based on different parameters and assumptions, such as roaming, and may therefore differ from the information shown here.

Why the Map was Prepared

This map provides a sample of the type of granular, standardized information that will become available as part of the Commission’s Broadband Data Collection project and serve as a preview of that work. It is, however, only a subset of the full set of mobile broadband availability data that will be collected as part of the Broadband Data Collection, when mobile wireless service providers will also submit standardized coverage data for their 3G and 5G mobile broadband technologies and other details about their propagation models and technical assumptions underlying their coverage maps. For more information, see the Broadband Data Collection homepage.

5G is the fifth generation of wireless network technology, designed to meet today’s growing data demands while expanding the scope of mobile technology beyond the capabilities of LTE. With 5G, large amounts of data can be transmitted much more efficiently than with 4G LTE, and that means faster speeds, less lag, and the ability to handle many more connections without buffering. Over time, these improvements will unlock amazing innovations and transform the way we live, work, and play. 

Learn more about 5G

You’ll need a 5G-capable device to access T‑Mobile's 5G network. If you have a 5G-capable device, good news—5G access is included in all our plans, at no additional cost. Don’t have a 5G device just yet? No worries, our 4G LTE network has you covered just about everywhere. 

We’re rapidly building out our 5G network—over 90% of Americans have access to T‑Mobile 5G today. While 5G grows, you can rely on our 4G LTE network that covers 99% of Americans. 

5G Extended Range is our low-band 5G network. It makes up the foundation of our nationwide 5G and brings 5G service to big cities, rural towns, and unexpected places in between. Our 5G Extended Range can deliver average download speeds 2x as fast as our LTE.

We’re continually deploying Ultra Capacity 5G in more places and are on track to have it deployed nationwide to over 200 million Americans by end of 2021.

Under the new Broadband DATA (Deployment Accuracy and Technological Availability) Act, all providers of fixed broadband or mobile services, including T‑Mobile, provide the FCC with specific information about where our services are available. The information submitted to the FCC provides detail on our coverage, specifically where customers may experience certain tiers of speed; it will be refreshed every six months.

Yes—5G is faster than 4G LTE, but actual speeds may vary depending on your device and network conditions. On average, 5G can deliver speeds 3x as fast as 4G LTE.

Yes, Sprint customers with a capable device can access T‑Mobile’s 5G network, but due to technical limitations, some parts of T‑Mobile’s 5G network aren’t available to Sprint customers yet. To view Sprint’s 5G coverage, visit the Sprint coverage map.

Strong, dependable network connectivity is more critical than ever, and by joining forces, T‑Mobile and Sprint are building the largest and most reliable 5G network. The new T‑Mobile network will deliver:

• More capacity – 14 times more network capacity in the next six years than T‑Mobile could offer alone. That means more power for streaming, gaming, downloading, and more.
• Crazy-fast speed – customers will have access to average 5G speeds that are up to eight times faster than current LTE in just a few years, and 15 times faster over the next six years.
• 5G for nearly everyone – within six years, the new T‑Mobile will provide 5G to 99% of the U.S. population, including rural America.

In more remote areas of the country, coverage may be provided by local wireless network partners. Most T‑Mobile plans include a limited amount of data in these areas. Check your plan or see roaming details. Look for the designated partner areas on our map. Signal strength will vary by partner. Not available for prepaid Mobile Internet (tablet and wearable) plans.

5G Ultra Capacity includes our mid-band and/or mmWave 5G. It can give you a perfect balance of far-reaching coverage and super-fast speeds, and we have this available in more places than anyone else! 5G Ultra Capacity can deliver speeds as fast as wi-fi right to your phone.

Every 5G device we carry today can tap into our 5G Extended Range and 5G Ultra Capacity.

Service in California may be impacted by temporary Public Safety Power Shutoffs (PSPS) or by events such as storms, fires, and earthquakes. In affected areas, the ability to place or receive calls, send, or receive texts, or access data may be impacted. Check out our California service impact map to see possible affected areas.­
