I've had my iPhone XS Max (on AT&T) for a little over a week now and I haven't had any issues with it until yesterday. I was trying to make a call and I got an error message saying:

Last Line No Longer Available
Do you want to call using your remaining line?

This happened on iOS 12.1 beta 2. I'm not using an eSIM, just my standard AT&T SIM card. I was in a hurry to make my call so I wasn't able to report it right away in the feedback app. This happened one other time this morning, when calling someone else.

Has anyone else encountered this? What could be causing it? I'm not sure if it's relevant, but I'm also using an Apple Watch Series 3 LTE on the same account. My AT&T account only has my iPhone and my Apple Watch active on it.

Try clearing all your contacts in recent call log and start fresh. It worked for me.
