Kim Kardashian West has an important message for everyone about unused data. Stop letting your carrier take back those unused megs & gigs at the end of each month. You’re missing out on so many amazing things. Like photos of Kim’s outfits. Or Kim’s vacation videos. Or even more of Kim’s outfit photos. With T-Mobile’s DataStash™, your unused data rolls forward, for up to 12 months! And we’ll even give you a welcome gift of 10 GB of free 4G LTE data, so you can start sharing Kim’s photos immediately. It’s your data. Keep it. Qualifying service required.
