The U.S. version of Nokia 3310 works on T-Mobile's network only
Introduced as a 2G feature phone that supports GSM networks only, HMD promised to work with carriers in the United States in order to find a solution to the issue. Unfortunately for Nokia fans, EDGE coverage on GSM networks is a bit of a problem in the U.S.
As such, the Nokia 3310 might only work on T-Mobile. The Federal Communications Commission (FCC) has recently approved a Nokia-branded mobile phone that goes by the model number TA-1037.
The TA-1037 is undoubtedly the U.S. version of the Nokia 3310 and, according to the FCC, it will only support GSM bands 850MHz and 1900MHz. The latter is used by T-Mobile, so the Nokia 3310 could be exclusively available through the Uncarrier.
