We are connected to wifi, turn ot to airplane mode at night, and still go over with data usage. We do not stream movies or music. We have talked with support numerous times. We were told that Verizon will override wifi if there is a stronger signal but we would be naware of that. We are told items update at night. Again, but if we are in airplane mode, how does that occur? Then, when I give in and add data at in increased monthly fee, suddenlythat is not enough data and we are over our limit again. We have not changed our behavior or use of the phones and we were fine with 6GB for months without even thinnking about it. So, we upped to 8GB. We were good for a short while, then suddenly we were using 10GB. Now three of us use 17-18 GB per month??? IMPOSSIBLE !!!!!!! And we are stuck if we don't wnat to pay the early termination. I feel like we are being taken advantage of.
