What is an eSIM?

If you have an eSIM compatible device, it means an embedded SIM is inside your device. With eSIM, there's no physical SIM card that you need to insert.

Like a traditional SIM card, an eSIM provides your connection to the Optimum Mobile network.

Some devices can simultaneously accommodate an eSIM and a physical SIM to have two wireless accounts with talk, text, and data on one device.   The device needs to be unlocked for you to have two different carriers on it.
