r/ATT on Reddit: Does the iPhone 12 Get 5G and 5G+?
May 13, 2024 -
Hello everyone! I have a question. I have a family member of mine, on the same phone plan with AT&T, who uses an iPhone 12 pro, and they get 5G and 5G+. They had switched to an eSIM, so I thought if i switched to an eSIM also, it would give me access to 5G and 5G+, instead of 5GE. Do I have access to 5G, but it says 5GE, or is there something else I would need to do?

3.7 GHz and mmWave 5G, yes, as well as the typical lower bands (n2, n5, n12, n66). No 3.45 GHz support though (you need the iPhone 14 or later for that). Also no n30 support, which is a band AT&T will probably use for 5G down the road.
5g compatibility in iPhone 12 - Apple Community
I purchased iPhone 12 in 2021 December from Amazon. It is mentioning 5g compatibility in product specifications but there is no such option in phone settings. Why apple or Amazon misguiding in this. I just checked as 5g services have just started in my state. More on discussions.apple.com
Canadian iPhone 12 and 12 Pro don't have mmWave 5G (taken from Canadian Apple site)
Only US models support mmWave 5G.

Yes, the LTE works better with the 12-series line up. This is probably since it’s a Qualcomm modem and not a Intel-modem. More on reddit.com
