Hi ​@Baaartman ,

As calls and texts are working, the SIM is active. Please try the steps below:
 

Check mobile data is on in your phone settings.

Check APN settings

APN: internet

Name: iD

Check your data allowance in the iD app or online account.

Set network mode to 4G/5G auto (not 2G/3G only).

Manual network selection → choose Three / 3UK, then restart the phone.

Test in another location or try the SIM in another phone if possible.

Hi ​@Baaartman ,

I’m really sorry you’re having this issue.

To get this sorted quickly, please visit your nearest Currys / Carphone Warehouse store. They will be able to assist you further and issue a replacement SIM.

Please take a form of ID with you, and they can activate the SIM for you within an hour.
