IMEI & SIM ICCID Drops Off AT&T Network?
Does anyone else have this issue? I own my own Samsung phones and just pay for monthly SIM service. It seems that every 6 months the device which is registered to my AT&T account drops off from being authenticated from AT&T's networks. I can make outbound calls but no one can hear me. I can receive SMS but not send. No LTE or 5G services work, I get a great signal but no IP address to use the data services. On my account, when I sign in there is no device displayed under My Device there is a icon with a "?" in it. I usually see my phone photo, model#.
I have to call in, provide my IMEI, Model# & SIM ICCID (which is AT&Ts) all over again, reboot and I am back on the network. This happened with my S20 Ultra 5G and now my S22 Ultra. Only this time around I could not find anyone else which understands the issue to fix it. After 4 people - they told me there is a state wide outage or update going on and they would get my issue looked at. There is no state wide outage or update. My AT&T straight talk phone works just fine.
