Google Fi plans cost $35 to $65 a month for one line, or $20 plus $10 for each gigabyte if you would rather pay for what you use. Google Fi Wireless is Google’s phone service, once called Project Fi. Its coverage page is plain about the network: “Google Fi Wireless provides fast, reliable nationwide 4G LTE and 5G coverage through the T-Mobile network.”
Google Fi plans and prices
| Plan | One line | High-speed data | Also includes |
|---|---|---|---|
| Unlimited Essentials | $35 | 30 GB | |
| Unlimited Standard | $50 | 50 GB | 25 GB of hotspot, data in Canada and Mexico |
| Unlimited Premium | $65 | 100 GB | 50 GB of hotspot, data in more than 200 destinations |
| Flexible | $20 plus $10 per GB | Pay for what you use |
Prices are from Google Fi’s plans page, read on October 8, 2026. Google says monthly prices do not include taxes and government fees.
After the high-speed allowance, all three unlimited plans drop to 256 kbps. That is a small fraction of the speed before the limit.
Fi gets cheaper per line fast
The single-line price is the worst case. Unlimited Standard is $50 for one line and $80 for two, then $90 for three and $100 for four. At four lines that is $25 each.
Does Google Fi use networks other than T-Mobile?
Google names only T-Mobile for coverage in the United States. The same page adds that customers with phones bought from Fi “have access to multiple carrier networks to stay connected as they travel domestically and around the world”, without naming them.
Does Google Fi support eSIM?
Yes. Google advertises that you can “Join instantly from home with quick eSIM activation”.
Data settings
Fi sets itself up on most phones. Google publishes manual values only for
picture messages on an iPhone: under MMS in Cellular Data Network, APN h2g2
and MMSC http://m.fi.goog/mms/wapenc. Those are from
Google’s Fi help page. We
found no published values for Android.
