Question about Apple iPhone 13 Pro Max

Hoi - i.e. you have 2 sim places - on the one hand a normal one for sim cards (the very small plastic chips) and on the other hand an electronic one for the so-called e-sim - which is given to you according to the provider and no longer requires a plastic card but is electronic... Wiki on this:
eSIM is a procedure for identifying the user in the mobile phone network without a replaceable SIM card. The subscriber information is securely embedded in a non-exchangeable module of the mobile terminal.
