My wife and I have always used less than our 1GB shared data allowance with Verizon Wireless. But this month We used 50% of our allowance in just a few days; and 75% after 11 days. The only difference I can think of is that we both started using our Apple watches--but not for downloading music or other large files. I don't know what caused the spike in usage. Does anyone have any ideas? Can this even be related to our Watches? Or should I look elsewhere?
