T-Mobile does not offer home Wi-Fi service, but the company does offers wireless mobile Internet plans with monthly rates ranging from $20 to $70, as of March 2015. The $20 plan includes one gigabyte of 4G LTE data per month, and the $70 plan includes 11 gigabytes.
T-Mobile's mobile Internet service requires a device that is compatible with a T-Mobile SIM card. This includes certain tablets, ultrabook computers and hotspot devices. When using this service in the home with a hotspot device, the user can connect up to 10 Wi-Fi-capable devices to the Internet. The hotspot device is small and portable.
T-Mobile rolls over unused data each month for up to 12 months for its mobile Internet subscribers.
