AT&T Phone not working with SIM

The only 950 or 950xl

I know the card is fine, because it is new from September 2023, and it worked well on my iPhone 5s.

Since The iPhone 5s has been excluded from the AT&T network since February of 2022, an AT&T SIM card could not have worked in an iPhone 5s in September of 2023. iPhone 5S is not capable of voice calls over the LTE network which would have been a requirement. Trying to use a SIM card in an iPhone 5S  in September 2023, would have resulted in a message that the phone was not compatible with the network, probably suspension from service until the phone was replaced.

So this post isn't passing the sniff test...  

Hello

Chcek below steps

1. Restart: Power off, remove the SIM, reinsert, and restart your phone.
2. Check Compatibility: Ensure the SIM is compatible with your device.
3. Verify APN Settings: Confirm APN settings match AT&T's requirements.
4. Reset Network Settings: Try resetting network settings.
5. Contact AT&T Support: Reach out to AT&T for further assistance.
