Many new devices now support Dual SIM technology, and that means the device can support two SIMs at once (whether it's one SIM card and one eSIM, or two eSIMs).

Only selected devices allow you to use two eSIMs at once, however.

Dual SIM is a game-changer for staying connected because you're no longer limited to one carrier (and one data plan). You have the freedom to stay reachable on your usual mobile number, even when you're halfway around the world, all without paying roaming fees because you're using a local eSIM for your data.
