Please review the following article 👉 If you see No Service, Searching, or SOS on your iPhone
If the above does not resolve the issue, then contact 👉 Official Apple Support OR you can always get your iPhone examined at the Apple Store 👉 Genius Bar Reservation and Apple Support Options or at an Authorized Service Center for further diagnosis and evaluation.
You may also contact your carrier to get a new SIM card if needed.
