Hi ​@Adamwarnock1 ,

Thanks for reaching out! I know it can be a bit worrying when your SIM shows “Unknown Number,” but don’t stress , this is usually something we can fix quite easily.
Here are a few quick things you can try:

-Restart your phone – A simple reboot often refreshes the SIM settings.
-Check your SIM settings – Go to your phone’s settings and make sure your number is saved under “SIM” or “Phone Number.” If it’s blank, you can enter your number manually.
-Refresh your network – Switch to airplane mode for a few seconds, then turn it off. This forces a network refresh.
-Reinsert your SIM – Take the SIM out, give it a gentle clean, and pop it back in securely.
-Update your software – Make sure your phone is running the latest version.
 

If it’s still showing “Unknown Number,” don’t worry – we’d love to help you get this sorted. You can reach us on Facebook or Instagram, via Live Chat, on our Community, or email us at socialqueries@idmobile.co.uk with your details. We’ll look into it and get things fixed for you.
