I have a Galaxy S20+ 5G in the Korean version and the model number is not under the list of AT&T phones that will work under the new 5G service. I was wondering if anyone knows what other Cellular company that can provide service for international or Korean phones in USA? I did not think this transition from 3G to 5G would affect my 5G device but sadly it does since AT&T puts restrictions regarding this matter and only certain USA phones with 4G and up can function under there network.
