What is eSIM?
Embedded SIM card/electronic SIM card—— eSIM (embedded SIM) is a tiny digital chip built into devices (like phones, tablets, or gateways). By applying to the operator for eSIM data to be written into the device's blank card chip, all functions of the physical SIM card are achieved; that replaces physical SIM cards, you can:
-
Store multiple carrier profiles (e.g., AT&T, Vodafone) on one device.
-
Switch networks remotely with a few clicks—no physical changes needed.
