I encorauge u all to go to Apple store, and say the problem u have, in my case the replace with a new phone cause the cannot fix the problem.

After showin apple personally the issue, they opt to replace my iphone to a new one, i hope with this new one it doesn´t happen the same shit. I´ll keep u all up to date.

at 21 of January i am in the same situation, i cant understand how they can allow this serious problem. I am literally without signal in the middle of the city, in fact it is easier to contact me with a morse code light than with my iphone 11. WTF rlly apple

same just installed 14.4 beta 2 same fckin shit, quite done with this. The fact that i cannot understand is why in my house it keeps stable ( but it fails sometimes) and around the town it goes so wrong
