Verizon executives have said in the past that shared data plans were on their way in 2012. According to a source that sent some info in to Engadget, Verizon's system is showing some training documents that lead us to believe that big red may be gearing up to make major data package changes to family plans. Verizon CEO Lowell McAdam said last year that we would likely see shared data pots for family lines and the training documents in Verizon's system seem to confirm that as they are talking about a Account level charge for data as well as a $9.99 charge per line. This is assumed to be meaning that you will pay a fee at the account level for a certain amount of data to be shared between all you lines, much like voice and text are done now.
It is still unclear when this may actually go live, but at least Verizon seems to be getting ready to train employees about it, which means we may get to see some more details in the near future. Just keep in mind this could be a while before it actually starts being offered and there is still yet that issue of how much will it cost. Let's just hope Verizon breaks from their track record of greed and makes it actually be cheaper for their customers.
