Disconnect from cell tower

[martimunk1]

Recently my iPhone has been dropping connection with a cell tower and hence have been unable to make or receive telephone calls. My husband has an identical iPhone and he has no issues!

Thus it could be YOUR phone's issue.

If you use Physical SIM make a swap and see if you get solid signal or not. If not - time for a new phone. OR... it could be loose contact with physical SIM... Clean contacts then.

if you both use hard sim's...try swapping sim's to see if the issue is phone related.
