Hi ​@Maryboyce,

 

Thanks for getting in touch, and I’m sorry you’re having issues making calls. I understand how frustrating that must be, especially when you’ve already tried restarting.

 

Please try the following steps:
Check you have signal bars and are connected to the iD Mobile/Three network
Turn Airplane Mode ON for 30 seconds, then OFF
Go to Settings → Mobile Network → Network Selection and set to Automatic
If possible, manually select iD Mobile / Three UK network
Remove and reinsert your SIM (or restart if using eSIM)
Try calling a different number (mobile and landline) to test


Also check:
Make sure no call barring is enabled in your phone settings
Ensure your phone number is correctly showing in Settings → About Phone
