I’ve just bought an eSIM for my daughter, we have opted to keep old number so entered PAC number when ordering. For set up it’s asking for ID phone number but won’t accept her number? Not sure how to get this sorted?

Hi ​@Helenkt,

 

I’m sorry you’re having difficulty setting up the eSIM.

Could you please confirm whether your daughter’s existing number and the new eSIM are both with iD Mobile? If they are, the number transfer will not work because iD Mobile cannot transfer a number internally between two iD Mobile accounts.

If her current number is with another network, please check that the PAC is correct and has been entered exactly as provided by her current provider. Once we know which network her existing number is with, we can advise you on the correct next steps.

Her existing number is with Vodafone,

we have just done this today so wondering if we need to wait a few days?

I have tried to set up the eSIM using her phone and it was asking about primary and secondary when setting up?!
