I had to switch recently to the 2-gb data plan (I'm sadly no longer grandfathered into the unlimited data package). Yesterday, I received a text from Verizon saying that my # had used about 75% of its prorated data allowance for the bill this month (today is the last day of that billing period). But when I go to My Verizon, it shows that I have used less than 50% of my 2gb allowance (only used .961gb). What am I missing here?
