Airvana Sprint cell phone repeater GPS help

[soloblazer]

Sprint sent me a Airvana unit because at my work i am in the basement and at that in the middle of the basement. They have verizon repeaters thoughout the building so i there is good verizon, but it wont roam on them. I have a sero plan so dont want to change to verizon, is there a way to use the airvana without the gps or a way to program it, if not i cant use it, any help would be great, thanks
