Half of all AT&T subscribers on unlimited data plans do not need them, suggests study

According to a recent study, nearly half of AT&T subscribers (about 48 percent) with grandfathered unlimited data plans use 300MB or less per month. Putting that into perspective, those subscribers have to pay $30 per month for something they don't really need. That is because a $20 monthly plan providing 300MB of mobile data would do just fine for these users, thus saving them $10 per month or $120 per year.

What is more interesting is that about 15 percent of those AT&T users on unlimited data plans consume less than 50 megabytes per month, while one percent of them do not go online from their smartphones at all. Perhaps, some people are just sticking to their old data plan so that they have truly unlimited data on their device in case they need it one day. But with all that extra cash they have to spend each month, is it really worth it? On the other hand, some of these people might just be unaware of the fact that they don't consume that much data as they likely have a Wi-Fi hotspot nearby all the time.
