New and existing customers on AT&T’s GoPhone monthly plans of $45 and $60 will now have rollover data added as a feature. The new plan goes into effect on May 15, 2015 and will be added to existing plans automatically. Similar to AT&T’s postpaid plans, if a customer uses 2GB out of 4GB, they will get the 2GB to use the following month for a total of 6GB. The unused rollover data is available for 30 days, and will only kick in after you have used your first allotment of data for that month.
In order to have access to the rollover data, users must renew their plan on time.
