hi there,
im looking at upgrading to a new plan with iD for an iPhone 15 Pro. I found the new plan on Carephone Warehouse for £36.99/pm with £69 up front.
im keen to keep my existing iD number, and simply upgrade to my new plan and cancel my current sim only plan for £10/pm, whilst retaining my existing number.
please could someone advise on how to do this?
