I think straighttalk from walmart is kinda cheap but I also think cingular or boost mobile are as well not just the top 3 att sprint or verizon. Tmobiles a joke
You cannot say that for every location!!!!!!!!!!!!!! All of them have areas where they are the best choice and areas where they are the worst. Just because T-Mobile does not work well where you are does not mean it is not the best choice in others!!!!!!!!!!!! Cell service is the same as real estate in that the key is location, location, location.
Straight Talk does not have a network of their own but agreements with the other providers of the towers, etc. They have a horrible reputation for anyone that wants to use beyond the minimum of data or in need of customer service.
