It is being rolled out in partnership with T-Mobile and Sprint and will offer seamless transitioning between the two cellular networks and over a million verified fast and reliable Wi-Fi hotspots. Plans start at $20, which offers unlimited talk and international texting. 4G data can be add at $10 per GB and you only pay for the data you use. Any unused data will be credited back to your account  at the end of each month. Your current phone number can also be ported over to be used with Project Fi and there’s no contracts.
