Learn about coverage and technologies of the T-Mobile network, needed for your device to connect.
T-Mobile is America’s largest 5G network and covers more people and places than anyone else.* While our 5G network continues to expand, you can count on our 4G LTE network that connects 99% of Americans.
- Access our 5G & 4G LTE coverage map from your computer or mobile device.
- Enter your address or a landmark, then press Enter or choose an item in the drop-down list.
- View the coverage in that area. You can also do the following:
- Click or tap and hold to drag to move the map around.
- Tap a location to get a pop-up with detailed coverage information.
- Use the + and - icons to zoom in or out. You can also pinch to zoom.
- Switch off 5G at the top to see where you're covered with 4G LTE.
5G Capable device required. Coverage not available in some areas. While 5G access won’t require a certain plan or feature, some uses/services might. See coverage details, Terms and Conditions, and Open Internet information for network management details (like video optimization).
If your phone has signal problems where we have coverage, see Signal issues / no service troubleshooting.
Quick tip! Easily check your phone's compatibility with our network using the IMEI Status Check. No need to compare network frequencies or device lists!
- Find the networks a T-Mobile device supports by checking your Device "Tech Specs" page (or, for non-T-Mobile devices, check with the manufacturer).
- To connect to the local network, your device must support both our network frequency (band) and the technology (5G, 4G LTE, 3G, 2G).
You can check if your phone supports the T-Mobile frequencies below in order to connect on our network. This can get technical, so it's a lot simpler to just use the IMEI Status Check if you have the device already.
Devices often support more frequencies than these, in order to roam on other domestic and international wireless networks. They are not needed on the T-Mobile network.
Extended Range (XR) 5G
- With Extended Range 5G, you’ll receive nationwide coverage, faster speeds than our 4G LTE and a reliable connection indoors and out from the big city to rural areas.
- Frequencies that can provide XR 5G:
- Band n71 (600 MHz)
- Check out What is 5G? to learn how it works!
Ultra Capacity (UC) 5G
- With Ultra Capacity 5G, you’ll experience a performance boost, a reliable connection in crowded locations, and speeds as fast as Wi-Fi.
- Look for the newly released icon on your iPhone screen to know when you’re in an area with our fastest speeds! (Coming end of year to Android)
- Frequencies that can provide UC 5G:
- Band n41 (2.5 GHz)
- Band n258 (24 GHz)
- Band n260 (39 GHz)
- Band n261 (28 GHz)
- Check out What is 5G? to learn how it works!
Speeds as fast as Wi-Fi based on analysis by T-Mobile of Speedtest Intelligence® data from Ookla® U.S. median 5G T-Mobile results compared to mobile Wi-Fi results from cities with 2.5GHz speeds for Q2 2021. 2.5GHz available only in select cities (see t-mobile.com/5GLayers).

Extended Range 4G LTE
- Frequencies that can provide Extended Range LTE
- Band 12 (700 MHz)
- Band 71 (600 MHz)
- Our Extended Range LTE signal reaches 2X as far and penetrates walls for 4X better coverage in-buildings than ever before.
- Frequencies that can provide LTE:
- Band 2 (1900 MHz)
- Band 5 (850 MHz)
- Band 4 (1700/2100 MHz)
- Band 66 (Extension of band 4 on 1700/2100 MHz).
- 4G LTE offers fast download speeds, up to 50% faster speeds than 3G. See Data speeds.
- Voice and data services only work at the same time when on you have VoLTE enabled on your device. Otherwise, LTE only provides data.
VoLTE ("Voice over LTE")
- VoLTE allows you to make and receive calls while connected to the LTE data network. It's available nationwide.
- Placing a call connects twice as fast.
- Switching between VoLTE and Wi-Fi Calling does not drop a call.
- What phones have VoLTE?
- All phones T-Mobile currently sells support VoLTE.
- To check if another phone supports it, use the IMEI Status Check. It will alert you if VoLTE or other LTE network features aren't supported.
- HD Voice
- HD Voice improves in-call voice quality for compatible phones on VoLTE.
- Voice call quality is more true-to-life, with less background noise.
- It automatically activates, if you and the person you're calling are both using supported phones on VoLTE.
- Enhanced Voice Services (EVS)
- EVS is another codec for HD Voice that further enhances call quality.
- It is available on specific device models, such as those made by Apple.
- Frequencies that can provide 3G: Band 4 (1700/2100 MHz) and Band 2 (1900 MHz)
- Voice and data services can work at the same time. You can use data while on a call.
2G (GSM, GPRS, EDGE)
- Frequencies that can provide 2G: Band 2 (1900 MHz)
- Voice and data services don't work at the same time when on 2G. You cannot use data while on a call.
*The T-Mobile network uses GSM network standards, and it's not a CDMA network.
