Dual eSIM
Okay, this might not be everyone’s favorite new feature, but the iPhone 13 lineup is the first one to support two active eSIMs. In case you didn’t know, eSIMs are digital SIM cards that you can have without using a physical nano-SIM.
You probably think older iPhone models could have an eSIM, and you’d be right. In the past, the iPhone XS all the way to the iPhone 12 could have a physical nano-SIM and an eSIM. But the iPhone 13 lineup is the first one capable of having two eSIMs simultaneously or a nano-SIM and an eSIM.
