AT&T customers now get to carry over their unused data from one month to the next. They used this concept years ago to mobile minutes, when most plans had limited minutes, the main difference being the rollover data is good for one month whereas minutes were good for a year. I am not complaining about rollover data only being good for one month because there are usually only one or two months out of the year when I might possibly need more data and that’s usually when I go on vacation or head home for the holidays and spend more time on cellular vs. WiFi. If you’re in a plan where you are constantly watching your data, my suggestion for you is to move up to the next plan. Data watching is no fun and implementing rules for your family is even less fun.
I have the 30GB family plan that I share with my siblings, which means if we used 20GB, we get to carry over 10GB to the next month. In the next month, we will have the extra 10GB, but use our first 30GB so the 10GB is only used to protect from going over our limits.
