I have a weak signal in my house and would like to know if we can use a sprint airave to boost our signal. I know we have straight talk plans, but we do use the sprint networks. I get a signal at my relative's house from their airave, but when I try to dial out on my phone it says that I am on a sprint private network, that it will not access. My phone is pretty much dead in the spot since the airave signal is 5 bars and over rides any nearby towers until I drive away from the house with the airave signal. Anyone have any ideas how we can get hacked into these private signal boosters?
