iPhone Se 2020 use in S. Korea
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.

Here's a bunch of useless information you never wanted to know and probably don't need to know, but here it is anyway 😂
Service providers like AT&T and T-Mobile are referred to as "GSM service providers", as is much of the rest of the world. However GSM is a 2G technology, which all US carriers are shutting off. (At&t did in 2017)
3g is UTMS, HSPA, W-CDMA
Every iPhone currently supported has HSPA 850 / 900 / 1700(AWS) / 1900 / 2100
Safe travels!
