Pros: Cost, customer service
Cons: Phone selection, lack of 3G
T-Mobile has been good to me over the years. There is no other carrier that I will get as much with as I get with them. That being said, it's gonna be time for me to move on if things don't change as far as phone selection and 3G coverage. I hear that there are great things coming up the pike so I'm keeping my fingers crossed.
