I was wondering if anyone knew how and why Verizon can charge so much more for its plans than T-Mobile. In the past, it seemed fairly reasonable, as Verizon's network was much stronger and more reliable than T-Mobile's. However, T-Mobile appears to have made up for lost ground with its 4G. Anyone have any ideas on this? I'm debating whether to stick to Verizon or switch over to T-Mobile - if the quality of service doesn't offset the price disparity, I'm probably going over to T-Mobile.
