AT&T is following T-Mobile's footsteps in the roll-over data space. AT&T wireless customers will be able to roll over their unused data for use within the next month.
"Beginning January 25, all new and current AT&T Mobile Share Value customers will automatically receive the Rollover Data feature at no additional cost," AT&T wrote on its website.
Unlike T-Mobile's Data Stash data rollover program — which debuted last month — AT&T's Rollover Data program will only let data be used the following month. T-Mobile's plan allows users to rollover data for year.
AT&T's rollover options also only apply to AT&T Mobile Share Value customers. Pre-paid customers or those with grandfathered older data plans are not eligible for the promotion.
