NEW YORK (AP) — T-Mobile is now letting customers carry over their unused cellular-data allotments for up to a year.
U.S. wireless carriers have been pushing consumers into larger data plans, but they typically lose what they don’t use at the end of their billing month. Under T-

Mobile’s plan announced Tuesday, customers would be able to stash what they don’t use for the future. Customers will also get a one-time free allotment of 10 gigabytes when the program starts next month.

The program is open only to customers on Simple Choice plans with at least 3 gigabytes for a smartphone or 1 gigabyte for a tablet.
Unlike other carriers, T-Mobile doesn’t offer plans in which families can share a collective pool of data. Like T-Mobile’s rollover approach, family data sharing give consumers more flexibility.
