Generally a physical nanoSIM is transferred before the migration process.

An eSIM is transferred as part of the migration process.


The duration of the transfer is entirely dependent on the amount of data to be transferred, the speed of your internet connection, AND how many apps need to be downloaded and installed.

Let's back up just a bit to clarify things.


Are you planning to buy an iPhone in the U.S.? We ask because new iPhones in the U.S. no longer use a SIM card at all. They use an eSIM......software....not a physical card.
