After adding support for U.S. Cellular last month, Google is once again beefing up its Project Fi cellular service.

Starting today, Project Fi customers can get high-speed international data in more than 135 countries and destinations. Google has added Three as a Project Fi partner, enabling data speeds that are 10 to 20 times faster than before.

This international high-speed data is being given to Project Fi customers at no extra charge. You just pay the same $10 per gigabyte rate that you’ve been paying all along and you’ll get high-speed data when traveling in more than 135 countries. You can see the full list of supported countries here.

To celebrate this new feature, Google is launching a special Nexus 6P deal. Starting today, July 12, at 10:00 am PT/1:00 pm ET, you can get $150 off the Nexus 6P when you sign up for Project Fi service. This’ll leave the 6P at a starting price of $349. If you do take advantage of the offer, you’ll need to keep Fi service active for at least 30 days, otherwise you’ll be hit with an additional $150 charge.

This Nexus 6P offer will be valid through July 19.
