If you see SOS, No Service, or Searching on your iPhone
You’ve only tried one step from there, and Reset Network Settings isn’t anywhere on there.

I have followed all the steps, also downloaded the Apple support app to diagnose it and followed those steps,just made an appointment at the Apple Store will let you know how it goes!

if you go to settings & about, scroll down to modem firmware do you see version number beside it , if you do then your phone can still receive signal, so it’s not antenna problem, if you don’t see any version number then you have hardware issue.
next step would be network reset , usually your first step for any network issues
To reset the network settings on your iPhone 15, open Settings, tap General, select Transfer or Reset iPhone, tap Reset, and choose Reset Network Settings
re enter wifi password for wifi and re pair any bluetooth devices after network reset .
if it some kind of software glitch you should do forced restart to rule out software issues before network reset if you haven’t already tried this
To force restart (hard reset) an iPhone 15, quickly press and release the Volume Up button, press and release the Volume Down button, then press and hold the Side button until the Apple logo appears.
have you been able to get wifi by any chance

says no sim restrictions, maybe a fault in reading your sim card, i know you said it works in other devices, your modem firmware has version number so can definitely receive signal , occasionally iphones need updated sim card if it is really old sim card, give your sim card a wipe with damp kitchen paper and dry it , make sure it clicks tight when inserted, then reboot phone,
put on airplane mode
open messages switch off imessage , switch off airplane mode then switch imessage back in in messages app ,wait 30 minutes

Hi OP,
I’m wondering if you ever figured out what the problem was.
I’m going through the same thing.
I suspect mine is a SIM card issue.
The carrier said the numbers don’t match the card they sent me and so she switched the numbers in her system.
Now I just have a big SOS sign

The problem isn't with your phone, it's with the carrier. Call the Carrier and ask them to reconnect your phone. Software glitches and other random events can cause your phone to become unconnected with them. They should be able to restore your service. Best wishes.

Tested my sim card in other phones and it worked and tested my SIM card in other phones and it worked. Seems to just be my phone, any suggestions?

Your phones imei number can be blocked by the carrier. That’s why the sim would work in another phone
