We have been with Verizon for a long time. We have never come close to using all our data. We rarely even reach the half way mark. Out of nowhere I get a text tonight that we're at 90% then a minute later it was used up. We have not changed anything. We use our wifi connection at home and don't use much when away from home. I sure hope it's a glitch and not Verizon pulling a fast one to get us to sign up for their new plan. I'm not happy. I may be looking for another carrier.
