I'm not sure about their roaming partner. But I love that most of sprint's plans include free roaming. As far as the phone it depends on what features you want. But I will say that Sanyo's are by far the best phones. Right now I have the Sanyo 8400. It's a camera phone and u can record video with it. I had the Sanyo 3100 it was also a camera phone. No camcorder though. Back to the 8400, it's a Flip phone, has a external antenna, bluetooth capable, media player, and a micro SD memory card.
I am a current tmobile customer and i was thinking about switching to sprint, and i heard that they are a roaming partner of Verizon, is this true? and also what sprint phone would you advise me to get.
