5 eSim Support
Notably, iOS 12.1 includes support for the embedded eSIM in the new handsets, which will allow new iPhone owners to take advantage of Apple’s dual SIM, dual standby capabilities. When it launches, users will be able to have two separate cellular plans and phone numbers on their devices. Though, of course, carriers need to switch this feature on, which is likely to happen after iOS 12.1 drops to the public.
