using maps and it freezes and phone goes to no service

Hi rossfromcampbellsville!
I understand that your iPhone is freezing and showing "No Service" when you try to use Apple Maps or Google Maps, and I'm happy to help. If you haven't already, please try restarting your iPhone:

If you're still having this issue, back up your iPhone before proceeding:

If the issue is still present, try restoring the iPhone to factory settings and setting it up as a new iPhone:
