Monthly plans start at $20 per month and are
flat fee-based, paid at the beginning of each monthly billing cycle. All plans include unlimited calls and messaging. Money for unused data is credited back to the user's account, while overuse of data results in a charge of $10 per gigabyte. When outside the United States, cellular phone calls cost $0.20 per minute, data costs the same $10 per
gigabyte (i.e., there are no extra data charges outside of the US), and texting is free. Data is free at full speeds between 6 GB and 15 GB for the duration of the billing cycle with Bill Protection. After 15 GB, data continues to be free but will be throttled to unspecified speeds. With the Unlimited Premium plan users get up to 50 GB of high-speed data in 200+ destinations and 256 kbps after. A data-only
SIM card can be used on tablets and other compatible devices, including the
2013 Nexus 7,
Nexus 9, and
iPad Air 2. The devices must be compatible with the T-Mobile network, and users can add up to 4 data-only SIM cards in one account (before July 2019 the limit was 9 data-only SIM cards in one account). A Group Plan, which allows users, referred to as "managers", to add other people, referred to as "members", to their subscription, costs an additional $15 per user. Group Plans let managers view data usage by member, set data notifications, add monthly allowances, and pause members' data usage. In June 2017, Group Plans were updated to feature "Group Repay", in which Google Fi Wireless automatically calculates each of the members' individual shares of the bill and allows for easy payments. Such payments can be a fixed amount, an individual's total usage, or only for data usage above the standard data allotment. == Reception ==
