My wife and I have Droid X's. I have an unlimited data plan for work, and she has a 150 meg limited plan. She has begun to exceed her monthly limit. A few days before the billing period ended, she tried to cut back on her usage by 1) enabling data saver, 2) trying to switch to wifi while at home and 3) staying off the device except for calls. She still ran over her limit for the period anyway, and has already run up more data time that she feels is correct. Enabling data saver did not appear to work. We thought enabling wifi while at home might also help limit her data useage, but we cannot get wifi to work. Are there menu items we should enable/disable that would help reduce data use?
