Question: does 2g work in usa?
Answer: The way US carriers have implemented things, 4G can get better range than 2G because it's on lower frequencies. Each carrier only has limited spectrum, and AT&T and T-Mobile haven't sold 2G-only devices for a few years now. ... AT&T turned off its 2G GSM network in 2017, leaving T-Mobile as the only 2G provider.
