Which carriers are on GSM?

AT&T and T-Mobile are the two main US networks that operate on GSM, that includes all MVNOs powered by AT&T and T-Mobile including Boost Mobile, Mint Mobile, Red Pocket, Tello and many more.

Is Verizon GSM or CDMA?

Recap

MVNOs provide a large selection of plans operating on the main US networks to offer something for everyone.

If you're happy with your handset, MVNOs make it easy to bring your own phone, as long as it's compatible. If you've currently got a Sprint or Verizon phone it may still work if it was made in the last few years. You can use our IMEI checker to be sure.
