I hear rumours that:

• Log in to the iD Mobile App or My Account online 

• Go to the My Account page and tap Thinking of Leaving

• Click Switch or Cancel Now 

• Choose Get PAC code and follow the instructions

might be of use.

Thank you but I have already left so this “thinking of leaving” option is no longer available on my account

You’ll need to contact support, and hope the number hasn’t been re-assigned to another SIM.

Did you happen to retain the pack sent with the SIM?  The card you push the SIM out of has a barcode.  The contents of which are written as plain text below.  I wager this number will assist in identification.

Hi @Lydia Peet 

For this, we’d typically recommend requesting a PAC code and using that to leave, instead of leaving then requesting a PAC code.
