I received a message saying that I had used up all of the data in my plan, with a little less than two weeks to go. My plan is 15GB, and I mostly just surf the web on my phone, so I was a little surprised to say the least. I reset my statistics yesterday at 4:00pm. A little more than 24 hours later, it seems I've used 837MB of data. That's with me turning cellular data off from about 5:45pm last night to 9:00 am this morning. I didn't listen to any music, watch any videos, download anything, or update any apps. I was mostly on Safari, and I checked out Twitter and Instagram a couple of times. I'm not sure how it's possible to use almost 1GB of data in what amounts to about 10 hours. Has anyone else had this issue? If so, is there any way to fix it? I don't want to be afraid to use my phone at the risk of incurring a crazy bill. Thanks.
