How many eSIMs can be used on an iPhone 16?
An iPhone 16 supports up to eight eSIM profiles. However, users can only have two active SIMs at a time. This can be a combination of two eSIMs, or one eSIM and one physical SIM, depending on the model. Switching between SIMS only takes a few taps in Settings > Cellular > Cellular Plans.
While the iPhone 16 does restrict use to a single line-in-use at one time, the ability to store multiple eSIMs means you can prepare ahead for trips without having to carry and fiddle with physical SIM cards. The iPhone 16 undoubtedly makes life simpler for people in need of multiple lines.
