I've searched here and the Internet and detailed info on eSIMs is pretty elusive.
I have a galaxy watch with a EE pay as you go eSIM, they have since closed the loophole to allow you to get a PAYG eSIM. My GW5 Pro LTE should (hopefully) be here any day now. I want to register the GW5 with a new eSIM, which is straight forward enough but I also want to keep the PAYG eSIM on the original galaxy watch but give it my daughter so she can register it with her phone.
The question is, if you register a watch with an eSIM to a new phone, does it deprovision the eSIM or retain it?
Reset the watch, pair to new phone and have ee re-link the number to the different line. (That line does not disappear as they are still charging for it) That's the theory however confirm with ee before proceeding as they would walk you through the process.(have swapped my esim across 2 different watches now) only snag may be that the new phone might need to be on your account but that's me speculating that requirement.
That seems like the only option as to pair watch to a new phone you need to reset it and doing that also disassociates the esim from your number. Any repairing will require EE assistance at that point!
