Verizon says it offers many ways to monitor your account during the month. From a PC you can go to "My Verizon" or "My Verizon Mobile" from a handset to obtain real time usage data. The carrier also offers a Data Use Calculator where you can plug in how many minutes of video or music you stream over Verizon's 3G pipes every month and get an estimate of much data you are consuming. Available on Big Red's Android phones and some BlackBerry models is a widget that will show your data usage with a quick glance at the screen. You can also click on the widget to reach "My Verizon".
95% of Verizon's 3G customers with unlimited data plans will not be affected. You probably will be under the 2GB monthly threshold even if you send 7,500 emails a month, visit 750 web sites, stream 150 minutes of music, watch 1 hour of high-resolution video, 5 hours of low-resolution video and upload 60 pictures. You should also be outside of the top 5% of data users if during the month you sent 7,500 emails, visit 150 web pages, view 1 hour of hi-resolution video, 5 hours of low-resolution video and upload 300 pictures.
Separate from Network Optimization, in certain markets, Verizon has already started its previously announced Video Optimization which means that data is sent efficiently in order to benefit the greatest number of users and could affect the way certain data files appear on your phone.
Typical data use on a smartphone
As the carrier has repeatedly made clear, you can reduce your chances of being in the top 5% and going over the 2GB monthly bar by using Wi-Fi whenever possible, switching to a 4G device, switching to a tiered data plan, or perhaps the most unsatisfactory option-cutting back on multimedia use and browsing on your phone.
