Hi

(iPhone 13pro max)

I get a few times a day no internet

I called EE and restarted a few settings as they instructed but I don’t think is that.

It s showing full 5 g and nothing works.

I try the wifi and that one doesn’t work either.

please don’t send me links on how to use recommended settings because you will waist our time.

I have seen my phone doing every 2 seconds :

you Are online and then you are off line for about 15 times.

I didn’t have this problem on iPhone 8plus
