Can an ATT iPhone SE 2020 be used in S. Korea? The ATT website specifically notes that for S. Korean and Japan, a phone must use 2100 MHz, but does not specify GSM or UMTS/HSPA.  According to the data the iPhone SE 2020 only lists 2100 Mhz for UMTS but not GSM.

I am considering upgrading my phone to the upcoming iPhone 12, and from my understanding it will be a 5G phone. I currently have a phone that is only 4G. I do not want to pay more on my monthly plan to use the 5G, so can I just keep my current 4G plan or will I be forced to upgrade?
