eSIM is a tricky thing: it lives not in the tray, but in the memory of the board itself

And when a technician replaces the board, the old eSIM goes with it. Not into the technician's pocket, but into the bin. So "the SIM disappeared" is not a trick or an attempt to confuse you, but a harsh technical reality.

So before visiting the service, do one simple thing: save the eSIM QR code or check the operator's app and find out how to reissue the profile for a new device. A couple of minutes at home will save you time without connection — and without the nervous search for someone to call from someone else's phone.

And there are also tariffs where reissuing an eSIM is paid or available only through support. Better to find this out in advance, while you still have connection, than after the technician is already waving a screwdriver goodbye.
