I've never had so much trouble trying to activate a replacement sim "EVER" 1st problem wouldn't accept activation code 2nd problem didn't send the bank any kind of payment request when I pressed the activate key. 3rd problem wouldn't accept cvc card from another bank ... Result really bad headache,phone nearly got thrown at my TV 🤨 and when I checked my bank giffgaff had took the payment... Half an hour later giffgaff app suddenly seemed to realise payment went through... Now my phone works again... Just wanted to say thank you to what is ending up to be the worst network ever.
