I have just purchased a monthly SIM for an iphone 14. The SIM arrived in the post and I am keen to get started. I want to keep the original phone number so I have been onto the website and have entered the PAC code, transaction number beginning with 4, old number, new number, etc. I then get an error message saying ‘Oops, something went wrong. Please try later’ I have tried about 6 times and have checked the information is correct and in the same format. Please can someone help me.

I understand that I am not the only person to have encountered this problem. It has now been resolved by a helpful Customer Service agent.I tried using the chatbot but gave up and asked to speak to a person. They asked me for the details and were then able to set up the switch for me. The bonus was that the switch happened the same day.
