T-Mobile vs. Sprint?

I am going to sign up for a cell phone contract next week, and I am torn between T-mobile and Sprint. I have heard that T-mobile has bad coverage, but Sprint has bad customer service. I am not interested in AT&T or Verizon, either. Which would you suggest - T-mobile or Sprint?

For choosing your cell phone carrier,Go to a phone shop in town, tell them what you want, they can advise.Before getting your cell phone service provider,Make sure your phone is unlocked and accept that carrier,If it's restricted by other network carrier means,You will need to unlock your phone.For unlocking you can approach your current network provider or else try to buy an unlocking service from any one of the online unlocking service provider like SuperUnlockCodes.com I hope it will be very useful to you.
