1.The frequency is the most important thing to choose a signal booster, because the GSM,3G or 4G means different frequency in different countries.
2.If there is still no signal after you install the booster, please adjust the outdoor antenna.You should get 1-2bars of stable signal in the location where the outdoor antenna is fixed in,or the booster can't work. Outdoor antenna should be installed 2 meters higher of your roof or put it on a high open place,so it can get better reception.
3.If you can get full bars signal after you install the booster,but can't make calls, please make sure that Outdoor and Indoor antenna are separated by wall to avoid interference . 


1.Please mount the outdoor antennas on the more higher location , and could receive receive 1-3 bars of stable signal, please confirm if make a right installation

2.It is better to determine the exact in different location until the highest signal strength is received on your phone(most amount of bars).Once you ascertain the best location then permanently mount the outdoor antenna, Keep the distance between the outdoor antenna and indoor antenna should be above 22ft and make sure a proper amount of physical separation

Dear sir , this item can work for the sprint cell service, what's your mobile service provider ? what's your mobile operating Band ? please tell us about this detailed information, and thenn we will give you the best suggestion to select a right frequency . 

Will this work on sprint 4g lte service and/or verizon 4g roaming (sprint roams on verizon) in washington state?

Our cell phone buster took us from 1x to 2 bars of lte with sprint and Verizon both 

Do I need an app

it doesn't need the APP , this iten can work on the sprint for Band2 , It can boost the cell signal and improve the voice and data , if you have the network frequnecy for Band2 , you can purchase it 

How do i set up an exchange for mine it doesnt work for my sprint phone unless it is sitting on top of it

Return it and order a new one. I would recommend downloading the network cell info app and making sure this repeater supports the band/frequency of the cell tower(s) in your area.
