Right now I am on Sprints network with an iPhone 4S. In 2 days I am switching from Sprint to Verizon for an iPhone 5S. I am trying to figure out my plan, but I am really confused on how much data I use. If I look on my iPhone 4S under cellular it says my data usage for this month is 5.5 GB. However, after monitoring it for a few months, at the end of the month my data is ALWAYS over 6 GB. Again, this is according to my phone, but whenever my bill comes my data usage is ALWAYS 2 GB or below. Because of these extreme differences, I am not sure how many GB I would need on a Verizon plan. Especially since I am going from the extreme deathly slow speeds of Sprint to a pretty decent 4G LTE speed of Verizon. Any advice?
