Oh dear! 😞 I'll see if I can suggest a few things. It's something I have seen in store a couple of times!
1. Have you double checked your APN settings?
2. Do you have any other network sim cards available to test in your handset? This will help us determine whether it is a network fault or a handset fault.
3. Have you requested a sim swap from customer services? Call 202 for pay monthly or 4445 for pay and go. But please bare with them, they're very busy at present.
4. Failing the sim swap, there may be a cheeky setting hidden somewhere in the depths of your account! I know we sometimes get the odd crossed wire. It's no ones fault, it happens to the best of us!
In this case, I would get in touch with customer services and see if you can escalate the issue to one of our lovely gurus. Someone from customer services should be able to have a good dig around the account and fix it for you.
Please note, this is not customer services and we cannot access your account. Do not publish personal details (email, phone number, bank account).
