T-Mobile coverage map guide

T-Mobile is taking Un-Carrier to our coverage maps. We are the only provider to enhance our coverage maps with verified customer data in order to build trust in our information.


The combination of engineering data and actual customer data shows a more trustworthy and accurate footprint of our network.



How the coverage map works

T-Mobile is changing the game by displaying maps that truly represent the expected network experience based on real customer data. The current industry standard uses estimates to approximate network experience, which only shows carrier's coverage maps as a rosy picture and leaves users skeptical.


Because of this, you rely on firsthand information like word of mouth, social media, or your own speed tests to try to figure it out yourself. You want to know if, where, and how your phone is going to work. The new T-Mobile coverage map is designed to show you exactly that.


T-Mobile is layering real customer-submitted data on its existing coverage map. We'll be able to show you the median download LTE speed tests results where enough data points have been collected in the last 90 days. You can see the technology footprint in a given area without having to enter a specific location/address.



Check coverage

  1. From a computer or mobile device, go to our 4G LTE Coverage Map.
  2. On the coverage map, enter an address or just the name of a city, and then select the CHECK COVERAGE button.
  3. If prompted for your mobile device's Manufacturer and Device, select them and then SEE MY COVERAGE.
    You can also SKIP this, but the map may be less personalized to your device.
  4. The map shows a popup with the information you're looking for: Signal strength, network coverage, and whether or not the information has been verified by T-Mobile customers.
    • When an area shows as Verified Coverage, a hexagonal icon appears, which means the vast number of connections are successful at the posted speed in that area. Information on connections in a given area is not always available and not all customers will get this posted speed for the area.
    • If the map does not show Verified Coverage, this just means that there is no customer-submitted data. The area still has the level of the coverage shown in the map (4GLTE, 4G, 3G etc.). Currently, we are only collecting data from Android devices and only from customers who agree to share.
    • The map displays 4GLTE/4G/3G/2G map indicators These indicate the network technology, with 4GLTE being the fastest.
    • The 4GLTE Device Compatibility icon means your device may not be compatible with our LTE Network. Click this icon to see device options. If you don't see this,your device will work fine.)
    • Click any area on the map to see pop-ups with details of typical indoor connectivity, and it can suggest indoor coverage options to get you more bars.
