From If you see No Service or Searching on your iPhone or iPad - Apple Support:

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.
