Can I use two eSIM at the same time?

All iPhone models that support eSIM can have multiple eSIMs installed and use Dual SIM with two active SIM cards at the same time. You can use Dual SIM by using one of the physical SIM cards and one of the installed eSIM. iPhone 13 models and later also support two active eSIMs.

Most cell phones will allow you to download several eSIMs and store them on your device. However, most devices will let you use only one at the time unless your device specifically supports several eSIMs simultaneously.
