There's no telling what T-Mobile has in store for this event, but the invite featuring a single tag-line falls in line with what we've seen from past uncarrier events. The only other hint that T-Mobile gives is a message saying it is "rewriting the rules of wireless again!" For a recap, during T-Mobile's most recent Uncarrier 8 event, the carrier unveiled Data Stash to the masses.
In any event, join us on March 18 at 12:30pm Eastern when we'll report on whatever the Un-carrier has in store. In the meantime, feel free to speculate below!.
