T-Mobile entices subscribers with stock options, weekly prizes, free in-flight Wi-Fi

Announced by CEO John Legere in his usual over-the-top fashion, the new set of offers is part of continued efforts to boost customer churn from competing networks, while at the same time solidifying T-Mobile retention rates. As with past T-Mobile incentives, existing subscribers net the greatest rewards from today's "Un-carrier 11" promotions.

For example, the stock program, called Stock Up, provides T-Mobile postpaid customers a single share of the company's common stock. Subscribers can net an additional share — up to 100 shares per year — by referring a friend, while customers who have been with the network for five or more years get an additional two shares for each recommendation until 2017.

The stock program is run through T-Mobile's brokerage partner, Loyal3. Owners receive the first share free through the T-Mobile Tuesdays app and pay no maintenance fees as long as they're active customers.

Users of the T-Mobile Tuesday app can also redeem a pizza from Domino's, a Wendy's drink and a special gift each week. Prizes come from a variety of brand partners including American Giant, Buffalo Wild Wings, Condé Nast, Fanatics, Fandango, Gilt, HotelTonight, JackThreads, Legendary Pictures and Universal Pictures, Lyft, Major League Baseball, MGM Resorts International, Samsung Electronics America, Inc., Shell, StubHub, The Clymb, The Grommet and Warner Brothers. This week's special gift is a movie from the VUDU movie rental service.

T-Mobile plans to vary prizes with new partners and each week award a major prize like a trip, private movie screening or sports event to a single customer drawn at random. Such prizes include stays in Las Vegas hotels, attendance at major league baseball all-star week in San Diego, a trip to the Peruvian ruins at Machu Picchu and a shopping spree in New York City.

Finally, T-Mobile is offering users an hour of free Wi-Fi access on Gogo-equipped domestic air flights in an expansion to the carrier's in-flight texting program. The initiative starts on June 13.
