I cannot connect to the network. Full service is shown with AT&T symbol next to it but LTE is not shown and I cannot receive/send SMS or calls.
Apple iPhone 7; AT&T 34.0; iOS version 12.1 (newest).
I can provide information regarding serial #, IMEI, ICCID, etc.
Thanks for your help!

We'd love to help you reconnect back to the network! There are several troubleshooting options we'd like for you to try. The first one involves resetting your network settings, which will be the seventh step on this page. This options resets Wi-Fi networks and passwords, cellular settings, and VPN/APN settings. Be sure to document/save your passwords before doing this.
You can also use our Troubleshoot & Resolve tool as well. You'll need to select your device to begin. Once you've done that, you can select Phone calls or Messaging beneath Service/network issues. We look forward to hearing back from you!

Hi. I had the same problem with my iPhone7, but solved it. This is what I did.
1.Insert at&t prepaid sim card.
2.Go to Setting, General, and VPN.
3.Delete former VPN setting of another sim card. 4.Then restart iPhone.
5.Date will work under the new VPN setting. The setting will be automatically set up with the at&t sim card.
I hope this information will help out especially those who used to use another sim card and have added VPN configuration setting under the sim card.

I have a SAMSUNG international 4G phone and an AT&T connection. This was working fine before the PIE 9 update. Since the update my mobile data stopped working. I tried everything, changing the APN settings, toggling, talking to SAMSUNG India and US to no avail.
Here is what was wrong: It seems like AT&T has 3G and 4G/LTE sims this problem is with their 3G sim it doesnt work with the new update unless you roll back to 3G APN settings. So the solution instead of doing all this is just to go to the AT&T store and ask them to try your phone with another display 4G sim. It will surely solve your problem.

I bought a prepaid SIM card at Austin with 8g data/month. It worked well for a month and suddenly can't connect sin Oct 1th. I checked the balance and data usage and everything seem fine. I had phone call to 2 customer service representatives separately but none of them solve my problem. I tried different phones and the SIM card doesn't work. Totally freak out!
