I had sprint for about 9 years there service sucked for the first 3 years but then imo was much better my cell service was great and my wireless cards where super fast but there customer service suckssssssssssssssss big time. now i switched to verizon. there wireless cards are slower then sprint and cell service seems about the same. to early to tell. if i could have verizon customer service with sprint coverage and speed tht would be ideal for me.
If you like their customer service now, just wait till you have a history with them...they will bend over backwards for you. Best of luck
