The Sleek is an all-in-one signal booster that works for virtually any phone or 3G or 4G hotspot. It works like this: The included magnetic mount antenna picks up the cellular signal and sends it through the cable to the cradle amplifier; the signal is then boosted and pushed out to the phone or device sitting in the cradle. All the necessary components for use in a car are included, and a home/office accessory kit is available for indoor use. The 2G/3G Sleek works for voice and 3G networks in North America, while the Sleek 4G works on all 5 bands used for 3G and 4G by US carriers (plus many international networks). For Canadian users, the 4G-C is compatible with the 3G and 4G networks used by Canadian providers.
