Thank you for the update @Bev3kids.
There are several possible reasons why the phone may not recognize it. It could be hardware related in which the SIM cardholder and reader is loose, so it doesn’t hold it in place. Issue may be SIM card related. Have you tried inserting another SIM card?
There are some self-service troubleshooting steps to try as well. Please feel free to visit our Troubleshoot & Resolve Tool. Here, you choose your Phone Manufacturer > then choose your Device > under Device/Software issues, please choose SIM Card. Here, you can follow a troubleshooting flow to determine the best resolution for your device.
If the device is still unable to read the SIM card, we encourage you to review your device's warranty and device protection options. You can also find out how to fix or replace it. You can also track your AT&T device protection or warranty options by clicking "Fix Now".
Meet us back here with the results if you have any questions, and we'll be happy to review some additional troubleshooting options. Thank you for contacting AT&T Community Forums.

Same phone and same sim card for 2 years now. Samsung note 10+. there are network bars. Tried airplane mode, restarting phone, removing sim card, clearing cache and data. Still nothing. I can use wifi only.
How can we improve?
