transfer esim to new phone

[Carbuilder]

Hello,

I have two requirements that I cannot find an answer to.

a) I have a new phone and would like to transfer my sim to it without affecting my current contract in any way. How do I do this?

b) I have a second number that I would like to bring over from Vodafone.  This number is used with a cellular Apple Watch with a Vodafone 'One Number'.  My question is, with O2, can I also have this feature?  If so, is it free, or is there a monthly charge?

Thanks,

You need a new esim pack to transfer the esim to a new phone.

Get one in store but take photo ID with you.

O2 charge £7 per month for a watch connection but I wouldn't advise you move to O2 for it as they have too many problems connecting watches.
