Error message when trying to transfer old phone number to new ID SIM

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.

Hi ​@Gtutcher ,

 

To transfer your number to iD Mobile using a PAC code, here are the steps:
1. Get your PAC code from your current network provider. You can usually request this by texting PAC to 65075 from your old SIM.
2. Insert your iD Mobile SIM into your phone.
3. Go to the iD Mobile website:

Visit idmobile.co.uk/pac and fill in the form with:

-Your PAC code
-Your old number (the one you want to keep)
-Your iD Mobile number (from the new SIM)
-Your transaction number (starts with 4, found in your order confirmation)

4.Submit the form. If successful, your number will be transferred on the next working day (or the date you selected).


5.Keep your iD SIM in your phone and wait for a confirmation SMS by 6pm on the day of transfer.


If you’re still seeing an error, try again later or contact us via Facebook, Instagram, or Live Chat so we can help manually process the transfer.
Let me know if you’d like help troubleshooting the error message.

@Gtutcher  Well that's excellent news that you managed to get it sorted and switched ASAP.
