I know this is an old thread, but can anyone give any insight into the best time in the data transfer process to migrate from an older physical SIM to eSIM on a newer iphone 14? I’m moving from a physical ATT SIM in an iPhone 8 Plus, that card probably started in an iphone 6s.. everything works fine, but I’m just a tad concerned when trying to migrate to a newer iphone 14 with it.
Does the migrate number SIM come up at the beginning of the data transfer process, or after all the data is migrated? I know I can select (don’t transfer number now) and then do it after all data is migrated to the new device, is this possibly better for SIM migration?
Thx for the response
UPDATE: Belay my last.
What I did was migrate all settings from the ‘old’ iPhone 8 plus to the new 14 plus device… NOT transferring the SIM just yet.
Once everything was fully converted over, any and all ios updates completed, I did the SIM to eSIM transfer between devices. Even though this SIM is probably from an original iPhone 6s (most likely the last time I bought an ATT phone, with sim, etc) the built in conversion process SEEMS to at least have gone just fine, took about TWO minutes and calls and data seem to work just fine. So, no crisis necessary.
