Samsung Galaxy A20 stuck in roaming despite having worked fine for weeks.
My Galaxy A20 was working perfectly fine, able to receive a 4G signal in my apartment, but as of earlier today it has been stuck in roaming while in and around my apartment. In fact, it did not start receiving a signal until I left town several miles away, and even then it was mostly 3G and spotty.
I don't know what could have caused this, but I've already tried restarting my phone, turning it off and on, resetting the network setting, turning airplane mode on and off, as well as dialing ##72786#. I need my phone to receive and make important calls, and it's also very useful for connecting to the internet. I would really like this to be fixed soon.
