Is T-Mobile a CDMA or GSM network?

By Rob Webber - Last updated on

T-Mobile is a GSM network carrier and works with GSM cell phones.

GSM - which stands for Global System for Mobile Communications - is one of two types of wireless frequencies used for cell phone service. CDMA and GSM provide 3G service to fill in the gaps when your 4G signal drops.

Over the past couple of years cell phone technology has evolved to allow most smartphones to run on both GSM and CDMA networks.

If you're unsure whether your device is compatible with a network, check with the carrier before buying your cell phone plan.

T-Mobile GSM network carriers

Of course you don't have to go with the bigger (translation: expensive!) wireless carriers. MVNOs, or Mobile Virtual Network Operators, are smaller mobile providers that use the very same networks as the big guys. They just give you better rates.

You can choose from a variety of plans from T-Mobile MVNOs like Mint, Ting, and Ultra Mobile, without sacrificing any of the network quality you get from the name brand.

  • Great bang for the buck: There are typically only small changes each time a new smartphone model comes out. Buying used gives you all the features you need without breaking the bank.
  • Keep control: Owning your phone without device payments puts you in the driver's seat. Leave your carrier any time you find a cheaper cell phone plan.
