Our one simple plan starts with the Fi Basics for $20/month. It includes unlimited domestic talk and text, unlimited international texts, Wi-Fi tethering to use your phone as a hotspot, and access cellular coverage in 135+ countries and destinations.
I didn't see a topic on this, new networks, specific phones only:
'These devices are the first smartphones that support our network of networks. They work with the Project Fi SIM card, which supports multiple cellular networks, and have a state-of-the-art cellular radio tuned to work across network types.'
