I wish I could save money with the newer plans... But my before tax cost would go from $70 to $140 a month just to get the 10GB plan. And then I would need to worry about going over that each month. While now, on the old plan, I have unlimited data, unlimited text, and 450 minutes talk(which I never come anywhere near with in network and after hours calling)and typically go over 10GB about every other month.
I just have no desire to see my bill double. If it was only $10 or $20 that would be fine but not double from $70 to $140!
