Hi everyone! So after a hard reset, or network setting reset my iPhone 6 will stay connected to AT&T for a while(un sure of the exact time it disconnects, over 2 hours though). Then it says no service. While saying no service it can still read the IMEI number. While it has service, it will say full LTE bars but be as slow as 2 bars on 4g or so. Any ideas?
Hmm. If it works for a few minutes then it is more likely to be a software issue rather than a hardware one. Have you tried a full factory reset, or going back to the last version of iOS? Does removing the SIM card and putting it back in help? If possible, could you try another SIM card for a few hours and see if there is any difference
