Google Fi Wireless's Unlimited Standard plan runs on T-Mobile for coverage.
It costs $150 per month for 6 lines.
It comes with unlimited minutes, unlimited texts, and 50GB of high-speed data per month. You get 25GB of hotspot data. Video streams at 480p quality.
Google Fi Unlimited Standard includes priority data, so you will get slightly faster speeds when the network is congested, such as during rush hour or at crowded events.
Taxes and fees are extra. Expect roughly $27.06 more per month, bringing your total to about $177.06.
Overall, I recommend the Google Fi Unlimited Standard plan because it is a good value.
