Our take
T-Mobile Home Internet Backup suits a household that keeps cable or fiber from another provider and wants a cheap fallback, since it does not need an existing customer account and includes the gateway. Its standby cost is $20 a month with AutoPay, lower than Frontier Unbreakable Wi-Fi at $25 and Verizon Wi-Fi Backup at $30, and it switches automatically, unlike Verizon. It runs on the T-Mobile network, so it is a different line from a Verizon backup. The catch is the allowance of 100 hours of data a month, after which speeds drop to 600 kbps until the plan resets.
