Google's mobile virtual network operator (MVNO) Google Fi is getting eSIM support on the iPhone. Previously, you would need to order a plastic SIM card to use Google Fi, but now iPhone users can set up service with just a few taps and clicks. You can even use it as a second mobile service on the iPhone now, with Google Fi on the eSIM and some other carrier in the physical SIM slot.
