Google became the first smartphone company to support built-in eSIMs with its Project Fi (now Google Fi) network last year. Now, it’s expanding that even further with the announcement of several new carriers around the world that will support the feature.

In addition to Google Fi, Google is adding support for Sprint in the US, EE in the UK, Airtel and Reliance Jio in India, and Truphone and Gigsky in various other countries over the next few months. In Germany, Deutsche Telekom and Vodafone will actually join Fi in offering the option to buy a Pixel 3 with an eSIM for those carriers sometime “soon.”
