AT&T announced that it will give a rollover data to its own Mobile Share Value customers. This rollover data program will be available to newcomers and to existing ones. The announcing of this program took place Wednesday, and, if a customer has unused data he had paid for in a month, the data can roll over to the next month with no additional charge. An example: somebody pays for three lines and 25GB of monthly data. In a given month he/she uses only 15GB, then the 10GB of unused data are going to be added to the services related to the next month. The effect will be that he/she will have 35GB of data for the price of 25GB. The data can be shared, this means that all three lines can make use of the additional storage.

This program will start from January 25, but it has has its limits. According to AT&T, any plan change triggers the expiring of the previous one, along with the rollover program. Also, if in the rollover month the unused data is not used, it expires with the coming of the next billing period. The concept of rollover has a certain past at AT&T. To limit the chance of  suffering additional charges, the calling minutes unused from one month could be added to the ones from the next month’s plan. AT&T decided to cast aside this feature when the industry transformed into one with no limit talk time. In the new wireless plans data is now the expensive component.

T-Mobile unveiled in the last month of 2014 Data Stash, a program that lets its customers carry any unused mobile data from one month into the following one(s). For comparison, T-Mobile’s rollover program gives the customer a 12 months period in which he can put to use any unused data. The Data Stash program will start this month too. In addition, every customers, new or existing ones, get an initial free data “stash” of 10GB. This bonus data will last for this whole year.

John Legere, the CEO of T-Mobile said that “If you buy data, it’s yours.”

AT&T as well as T-Mobile are looking for new types of features to attract subscribers. The rollover program seem to be a part of this competition.
