Getting started with an eSIM
What are dual SIM and eSIM?
An eSIM (short for embedded SIM) is a digital SIM that’s built into certain mobile devices. It lets you activate a plan with a phone number without needing a physical SIM card.
A Dual SIM device is able to use two SIMs instead of one. Depending on the device, this can be a combination of physical SIM card(s) and/or eSIM(s).
With a Dual SIM smartphone, you can have two phone numbers on a single smartphone for calling and texting (SMS and MMS). For example, you can have separate personal and business numbers. The two phone numbers can be on the same account, or on different accounts.
