How can you say the price of T-Mo are better then Sprint when Sprints offers Unlimited calls to any mobile, unlimited data, unlimited navigation, Sprint TV premier, Music Premier, unlimited text, unlimited nights and weekend, and 450 minutes for landlines (honestly who calls landlines now a days? All this for 69.99.
I don't see any T-Mobile plan that has all this for the same price.
I have a Fav 5 account with 300 minutes, no text, and not even free t-mobile to t-mobile for 39.99. With less than 10 text a month my bill goes up as high as $54+.
As for coverage, some of my friends can't even get a reliable 3G connection on their own house, while another friend would go around town and will always get a 3G connection. Mind you, the their house said that it should have full 3G connection from T-Mobile Data coverage map.
As for customer service, I have to say, T-mobile customer reps are good. Haven't had any experience with Sprint since I will be transferring once the latest phones get released. My main reason for transffering will be because of Price and better coverage. Not sure where you are in the Bay Area, but I don't have full bars in some areas. Like Hayward, Alameda. But pretty much had full bars in Oakland and San-Francisco. AT&T had better coverage in the East Bay in my opinion.
In Texas, most of my friends, co-workers and family have T-Mobile, but I have to admit, I'm dissappointed with T-Mo's data coverage. Even comparing with their data coverage maps. we struggle to continually get a 3G connection. This is with a clique that my cousin has. And he's contemplating a switch to Sprint, too bad he has to fullfill a 2 year contract... Too bad for him.
As for me my contract will expire early this April. I hope the Nexus One or the SS will be out by then.
