Hello:': Was in a store that sells Alltel today. Lady there says Alltel does not roam on Sprints network. Said they only roam on Verizon. She said Sprint will roam off of Alltels analog, Any truth to that? Had wondered since there is a 8 mile stretch near me that Alltel goes out but sprint will work. Thought if Alltel roames on sprint they would jump to sprint network, Just wondering Does Alltel roam on Sprints digital network for free?
