Unequivocally Plug and Play.

Simply plug Cel-Fi's Mobile Phone Signal Repeater in. Cel-Fi is absolutely void of any antennas, cables, switches or configuration needs, making it totally plug and play. Since both units communicate wirelessly, you can put them in the best location in your house or office, and Cel-Fi configures itself automatically.

Safe and secure connection to T-Mobile

Your communication and data are secure. Because Cel-Fi repeats T-Mobile wireless signal, it maintains all of the security protocols of the T-Mobile Wireless network. Your call or data session is never transmitted over the internet.
