If I have No Cell Service at all, will a Signal Booster help?
An answer to this depends on the cellular service readings you are able to achieve outside the house or building property. If you can achieve a cell phone signal between -50 dB and -103 dB outside of the building where an antenna can be placed, a cell phone signal booster should effectively improve your cell phone signal inside the building. However, if the best signal you can receive outside the building is between -104 dB and -150 dB, and you don't have a clear line of sight to a nearby cellular tower within a 20-mile radius for our directional antenna to grab signal, a cell phone signal booster will not improve the situation, regardless of the type or manufacturer of the booster.

What distance from a cell tower will a cell phone booster work?
This is a very vague question because it depends on obstructions that exist between your cellphone, and the nearest cell phone tower. A more precise way to check is to try making a call from several points outside, and around your house. If you can make a call, or there's a cellular tower within atleast twenty miles, most likely a signal booster will be able to help.
