ios 14.5.1 didnt change anything about network. Very2 annoying about this problem. Hard to get network , and impossible to get LTE since september 2020. This is last time i buy iphone, no ios anymore ! Apple should read this !

Still the same ios 14.4 on iphone 11 pro max. Already 6 month using hotspot from another phone. Very hard and waste time to search gsm network with airplane on/off. After getting the gsm netrowk, even more difficult to get the 3g or LTE network. Very disappointed to apple can't solve the problem after 6 month. Maybe i will change the cellphone soon, not use apple product anymore.

ios 14.2 still no network, no cellular data. so hard airplane mode on/off for searching network. after a long search, have network but no cellular data (LTE / 3G). hate this situation, must hotspot on another smartphone for using my iphone 11 pro max. i think if apple not repair this problem, apple user can move to competitors smartphones.
