My dad uses Sprint through work. I don't know how the internet is, but I hear a woman say "Please hold while the Nextel subscriber you are trying to reach is located. Por favor espera mientras el cliente de nextal a que esta llamando es localizado" way way way to often. It changed to a dude recently... Point is, his phone service is finicky. It changes from 1 bar to 5 bars when he's just sitting on the couch.
