Last Line No Longer Available on iPhone 14 (with answer)

Symptom: Each time I touch an entry in my phone favorites

list to place a phone call, a window appears that says, "Last Line No

Longer Available. Do you want to call using your remaining line?"

Apple tech support helped me and solved the problem.

Background: the day previous, I'd upgraded to a new iPhone 14.

My apps and data were transferred by Bluetooth to the new phone

from my iPhone 6s.

Explanation: my new Phone app's Recent list held many call

records from the old phone. I was directed to clear them all, then call some

number that answers. (If the "no longer available" message appears again,

say yes and complete that call, then repeat. However, I didn't need that step.)

Resolution: clearing the Recent list allowed calls to proceed

normally.
