Typically, each phone comes with 1 physical SIM and 1 eSIM, or it might have 2 physical SIMs, 2 eSIMs - depending on the phone model. Having multiple eSIMs on one device is entirely possible. However, the maximum number of eSIMs you can use depends on whether your device supports it.

Nevertheless, you can only activate one eSIM at a time.
