Google Pixel 2 & eSIM

The Google Pixel 2 and Pixel 2 XL have what's called an "eSIM" — essentially an embedded SIM card that can be activated and deactivated on the fly to emulate a physical SIM card. But you don't have to know the details about how it works — you just need to know that it's an amazing innovation that makes it dead easy to use Google's Project Fi cell service on your new Pixel 2.

f you intend to give Project Fi a try, all it takes is downloading the Project Fi app on your Pixel 2 or 2 XL. Set up your account, and it will recognize that your phone has an eSIM. It takes just a couple of minutes to assign your phone number to the phone and enable service, and you're ready to go. Yes, it's really that easy.
