Ever since AT&T started throttling its users on unlimited data, it has been very mysteriously how AT&T decides who is on the top 5 percent of data users to reduce the device data speed. Some users have report that AT&T throttled them for using less than 2GB of data, after using 2GB, and some users on unlimited data have never been throttled even after using 5GB of data — that’s why it has been unknown how AT&T decides who’s on top 5% of data users. Today, after receiving many complaints, AT&T has finally officially announced who and how customers will receive be throttled for now on. According to AT&T’s announcement, customers who use more than 3GB of data will be throttled and are allegedly in the top 5% of data users. Customers with 4G LTE smartphone can use 5GB until AT&T throttle them.

 if you use more than 3GB, which means you are in the top 5% of data users in our network. If you have a 4G LTE Smartphone with monthly data usage over 5GB  

This puts users on unlimited data plan to only have one advantage compared to tiered data plans, and that is that they get two extra GB if an 4G LTE capable smartphone is being used. Both users still pay the same amount of money.
