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.

@Leah_ Have you talked with AT&T to see if they can add your phone info to a list of 5G capable phones?

No, I didn't. I didn't know if you can since Korean 5G phones probably runs differently from USA. I will contact AT&T and see if it is possible.
