We have sprint. I have never missed a call. I got a couple of voicemail messages a few hours after they were left once, but they fixed it I guess, it hasn't happened in a few months. PLUS all of my family is on Sprint and a lot of our friend and the network is just huge! So we rarely get anywhere to using up all of the minutes that we share with my sister in law and brother in law. I think they pay 165 for 1500 minutes and 3 lines... I think.
Oh the only place I can't get a signal is in Sam's.
