I have unlimited data, but my data has not been working for the past 2 weeks. I’ve tried resetting data connection, I’ve checked the connection strength in my area and there are no issues. What can I do to fix this?

Fear not
You only need to ask for a replacement SIM (granted the SIM will be new, but its not on another/new contract).
So no, you keep your existing package.
Then, after popping into Currys you then need to do the following to activate this replacement SIM on your contract:
- Open the iD Mobile app or log-in to My Account Online.

- Tap ‘Activate a replacement SIM’.
- Enter and confirm your 19-digit SIM card number.
- Tap ‘Activate your SIM’
But note the first 8 numbers of that SIM are already filled out:
