I’m upgrading to a newer phone and both models support eSIM, but I’ve heard that moving a number can still require help from the carrier. What can get in the way of an eSIM transfer when the devices themselves are compatible?
I’d especially like to know whether the phone’s operating system, carrier account settings, or a regional model difference can affect carrier activation. If the transfer fails midway, is there a risk of losing service on the old phone before the new one is ready?
