My iPhone 11 Pro Max had a way to force 4G in the Cellular setting and 4G signal was always strong and stable than LTE in my neighborhood. However, my new iPhone 12 Pro Max doesn't even have 4G in the setting. I can force LTE but 4G. Both LTE and 5G signals are spotty and weak and they are not usabl

Just got a OnePlus and it is defintiely LTE compatible based on the device specs (says it is bands 4/17 compatible).    Now, when I spoke w/ ATT on the phone they said the device may not work at LTE speeds.

Hi all. I'm sure the 3G/2G phase-out has been discussed a bunch here. My unlocked Samsung Galaxy S10e is an Asian model but fully supports 4G and VoLTE. I've been using it on AT&Ts network for 1.5 years but they did-not or would-not activate VoLTE. The 3G/2G phase out in Feb-2022 now appears t
