Hello Seekerbloke,
Welcome to Apple Support Communities!
The article you came from, If you see No Service, Searching, or SOS on your iPhone or iPad, is the best resource for the issue you are having with No Service.
"Check for a Carrier Settings update
To manually check for and install a carrier settings update:
- Make sure that your device is connected to a Wi-Fi or cellular network.
- Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
- To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.
If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.
Turn your cellular line off and back on
Go to Settings > Cellular and check to see if your cellular line is turned on. If your cellular line is off, turn it back on. Then check to see if you have service.
If you don't see your cellular line in Settings > Cellular, you should set up an eSIM or insert a physical SIM card. If you're using a physical SIM card, remove the SIM card and put it back in.
If your SIM card is damaged, doesn't fit in the SIM tray, or you transferred your physical SIM card from another device, ask your carrier for a new SIM card.
Learn more about removing your iPhone SIM card or iPad SIM card.
Reset your Network Settings
Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before."
Let us know if you have any questions.
