I upgraded my soon to expire 12 month iD eSIM only plan to a new 24 month eSIM only plan. Unexpectedly, when I downloaded the new eSIM it has a new number. The information on the product info on the website suggested I would keep my old number when upgrading.An upgraded mobile plan with a new number is completely useless to me (and I'mbaffled why anyone might want to do this as a default feature when upgrading with the same provider).How do I reinstate my old number on the new eSIM?
