My Wife and I are on the good deal from ATT, the 2 phone lines shared, both with unlimited minutes, unlimited texts, and 10GB shared data. Total with taxes is like $145 / month In the past couple years, I was typically at 2.5GB to 3GB user, my Wife like 1.5GB. Well the past several months my bill is like $280 each month !!!! And says I am going over the 10GB shared data each month, by like a few GB's, of total like 14GB a month. WTF how's that even possible. We haven't changed our usage in years. We never watch movies on our phones. We don't game whatsoever on our phones. We text, and surf the web the most, and make tons of phone calls. And we do check out YouTube, but nothing too large or full length shows or anything. Just little videos here and there. How come, the past three years my Wife and I got by fine with using like 2.5GB each a month. And now all of a sudden we witch to the 10GB shared earlier this year, and we're going over it every month, and getting whacked ?
