My phone was working great until yesterday. All of a sudden, no 5g. I gave it a cold and warm boot, I reset the settings. I was on the phone with t-mobile several times, They refreshed it. Then I went and got a new Sim card. It worked initially and then it disappeared again. So I can't get on the internet. My phone calls and text work. It keeps prompting me to register the network. I do and it still doesn't help. Sometimes I get 3g or E but no 5g. It wants to register the network frequently so it's apparently kicking me off,. BTW, my adroid version is up to date and mobile data is turned on.
Any suggestions would be appreciated.
