T-Mobile network bands & technologies

T-Mobile supports various wireless network technologies, as described below.

 

 

 

Coverage & device support

Check out our coverage map to see what areas we service. To connect to the local network, a device must support both:

 

  • The frequency (band) our network uses in the area
  • The technology (4G LTE, 4G, 3G, 2G) that local network is using on that band

 

See what frequencies (bands) and network technologies a device supports in your device's Tech Specs document. To gain coverage for more radio frequencies/technologies, you must upgrade to newer devices that support them.

 

If your phone is having problems connecting to a network it supports, see Network connection issues.

Network technologies

4G LTE

  • Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz), Band 12 (700 MHz), Band 66 (Extension of band 4 on 1700/2100 MHz), Band 71 (600 MHz)
  • Voice and data services can work simultaneously only on VoLTE. (If VoLTE is turned off or the device does not support it, then LTE is only data.)
  • 4G LTE offers incredibly fast download speeds, up to 50% faster speeds than 3G.
  • VoLTE
    • VoLTE (Voice over LTE) allows you to place and receive calls on our LTE data network, and it's available nationwide.
    • Placing a call connects twice as fast.
    • Switching between 4G VoLTE and Wi-Fi Calling does not drop a call.
    • HD Voice on VoLTE
      • HD Voice is a feature that improves in-call voice quality nationwide for compatible phones.
      • 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.
  • Wideband LTE
    • Wideband LTE delivers up to 50% faster LTE speeds, on a network that's already delivering blazing fast speeds.
    • Increasing to wideband provides both greater speeds and the ability to handle more customers.
    • This is created by expanding our basic 5 + 5 or 10 + 10 LTE capacity and increasing it to 15 + 15 or 20 + 20.

 

4G (HSPA+)

  • Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
  • Voice and data services can work simultaneously.
  • 4G offers incredibly fast download speeds, nearly as fast as 4G LTE.

 

3G (UMTS/HSPA)

  • Frequencies: Band 4 (1700/2100 MHz)
  • Voice and data services can work simultaneously.

 

2G (GSM, GPRS, EDGE)

  • Frequencies: Band 2 (1900 MHz)
  • Voice and data services cannot work simultaneously when on GPRS or EDGE. Data does not work while on a call.

 

 

 

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.
