How to manage and use dual SIM and eSIM (embedded SIM) on your Samsung Galaxy smartphone

SIM manager
Your wireless service provider and service plan may support the ability to use a dual
SIM (two physical SIM cards) or an eSIM (embedded SIM) so that you can manage two
mobile accounts without carrying two devices. Options may vary by service provider.
Devices that support dual SIM contain two SIM card slots. It may also have a microSD
card slot for expandable storage if supported. Devices that support dual SIM will
receive software updates that enable the built-in dual SIM capability after launch.

Devices that support an eSIM can be programmed to work independently of the
physical SIM card in the device. This allows for either the eSIM or the physical SIM card
to be used for voice call/text and data. Devices that support eSIM will receive
software updates that enable the built-in eSIM capability after launch.
