Apple describes carrier activation, QR codes and other supported methods. There is no single procedure for every phone.
FinFly Explains / Gadgets
What eSIM is
eSIM activates a mobile plan without inserting a physical SIM. Check availability for the particular device, region and carrier.
Moving a number is separate
Transfer options depend on carrier and device support. Do not assume copying the rest of your phone’s data also transfers its mobile plan.
Before travelling
FinFly recommends checking model compatibility, calls and SMS, validity and reactivation terms. Save support contact details before departure.
After installation
Test service before abandoning the previous connection. Apple recommends a test call on iPhone; follow the relevant manufacturer’s guidance for other devices.
