When using the 4G LTE CellSpot V2, your data speeds will vary based on your internet connection, simultaneous voice and data sessions, and other factors. T-Mo says that no existing in-home signal is required, but customers must be within T-MobileвЂ™s coverage area to use this device. (There is no purchase option.) The device connects to your in-home internet connection and a GPS antenna to provide you with a cellular signal. T-Mo will loan the 4G LTE CellSpot V2 to qualified postpaid customers without a monthly fee. It does not support Band 12 LTE (700MHz). It supports up to 16 simultaneous connections (8 on 4G LTE and 8 on 3G/4G UMTS), covers an average of 3,000 square feet, and can be accessed by any T-Mobile customer within range. T-MobileвЂ™s 4G LTE CellSpot V2 gives you a dedicated LTE connection in your home, complete with 4G LTE voice and data.

The 4G LTE CellSpot V2 is an updated version of the device that T-Mobile launched two years ago. Recently, T-Mobile quietly released a couple of devices meant to improve the signal that you get at home.
