SprintingWorm it would also be difficult to use If iit s locked by a code and if a Google account is set the Google FRP Lock wouldn’t let anyone use the phone even after it is reset.
The eSIM data also could be deleted, at least by resetting the phone, for there is a option to Factory reset and erase the eSIM. And also most of the phones which uses eSIM could also be used with a nanoSIM.
Maybe I am getting this eSIM Lock wrong, but I don’t think it is more secure than using the Device lock code.
Unfortunately my devices does not support eSIM, so I didn’t get to try it.
