T-Mobile network

Learn about coverage and technologies of the T-Mobile network, needed for your device to connect.


Keep in mind, you may try the service in your area with the Lifetime Coverage Guarantee!




Coverage map

T-Mobile is changing the game by displaying coverage maps with real customer data. The map can show you the median download LTE speed test results (where enough tests have been run in a 90-day period). Data is aggregated and not personally identifiable.


  1. Check out our coverage map from your computer or mobile device.
  2. On the coverage map, enter an address or just the name of a city. You can see the technology footprint in a given area without having to enter a specific location/address.
  3. Click CHECK COVERAGE. The map shows a popup with location information.
    • The pop-up shows the address, if coverage is verified by customer data, 4G LTE availability, and expected signal (indoor and outdoor reception).

    • Hexagon icons appear where there is Verified Coverage, which means the majority of customers successfully connected within a 90-day period.

    • If the map does not show Verified Coverage, this just means that there isn't enough customer-submitted data. The area still has the coverage shown.

  4. Click and drag to move the map.

  5. Click other areas of the map to see pop-ups with details.


If your phone has signal problems where we have coverage, see  Signal issues / no service troubleshooting.



Device compatibility


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). If you want more radio frequencies/technologies, you must upgrade to a newer device.


To connect to the local network, your device must support both our network frequency (band) and the technology (4G LTE, 4G, 3G, 2G).



T-Mobile network frequencies & technology

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.


FrequencyBandNetwork technology that works on this frequency
39 GHzN2605G milimeter wave (in pockets of select cities)
28 GHzN2615G milimeter wave (in pockets of select cities)
1900 MHz2





1700/2100 MHz








850 MHz5


700 MHz124G LTE
600 MHz71



*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.



Keep an eye on our 5G developments at the T-Mobile Newsroom.



  • Frequencies that can provide LTE: Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 5 (850 MHz), Band 12 (700 MHz), Band 66 (Extension of band 4 on 1700/2100 MHz), Band 71 (600 MHz)
  • 4G LTE offers incredibly 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.
  • Wideband LTE

    • Increasing to wideband provides both greater speeds and the ability to handle more customers.
    • Our Wideband LTE delivers up to 50% faster LTE speeds, on a network that's already delivering blazing fast speeds.


4G (HSPA+)

  • Frequencies that can provide 4G: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
  • 4G offers incredibly fast download speeds, nearly as fast as 4G LTE. See Data speeds.
  • Voice and data services can work at the same time. You can use data while on a call.



  • Frequencies that can provide 3G: Band 4 (1700/2100 MHz)
  • Voice and data services can work at the same time. You can use data while on a call.



  • 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.



International coverage

Our maps show coverage provided by T-Mobile in the U.S. T-Mobile partners with other providers who have coverage in other countries. Check out where you are covered when Traveling Abroad.



Data speeds vary depending on its operating system, processor, battery life, running applications, peak theoretical speeds, and distance from the cell site. USB laptop sticks almost always offer higher speeds than smartphones, because they use the power of a laptop with larger batteries, processors, and other technologies. Also, downloading information is faster than uploading. There is no way to predict an exact speed with so many factors affecting your experience.


Not all LTE frequencies are available in all T-Mobile coverage areas.

For the best experience, we recommend using streaming services over 4G and 4G LTE.
