Sprint is improving, but has a way to go at my house. We've ordered a Wilson dB Pro cell booster and antenna kit. I think it's the only solution that will enable me to use the phone in the house.
If you have dsl or cable broadband you could get a contract and they would sell you a femtocell.
They don't have one available on their pre-paid brands as far as I can tell.
