T-Mobile is holding its Uncarrier 11 marketing campaign kickoff event on Monday, and more information has come to light about its unique offer enabling customers to earn shares of the company’s stock.

According to the same person who earlier provided VentureBeat with details about the weekly freebie promotion known as T-Mobile Tuesdays, the so-called Stock Up initiative will give postpaid subscribers the opportunity to bank up to 100 shares of TMUS per year (currently trading at $43.73 per share).

There are allegedly two ways in which customers will be able to earn shares: an initial, qualification-free giveaway, and as a referral fee for driving business to the carrier by way of friends and family.

Any existing postpaid subscriber who downloads the T-Mobile Tuesdays app prior to June 21 will automatically be eligible for a single share of stock (and not the quarter-share we originally reported). Claiming the share will require customers to sign up with Loyal3, a web service that offers fee-free investing in popular brands’ stock.

New customers will have a rolling three-week window in which to claim their shares at Loyal3’s web portal.

Following that initial share at sign-up, 99 more can be earned per year by referring people who maintain their accounts for longer than 15 days (a fraud prevention measure designed to outlast a new line’s return window). As a bonus for long-term subscribers, those who have been with T-Mobile for five years or longer will get not one, but two shares per new customer referred.

In order to claim the referral fee, the referrer need only enter their friend’s or family member’s phone number into the T-Mobile Tuesdays app.

Besides the free stock aspect of the promotion, the customer appreciation initiative pays out a single, two-topping Domino’s pizza, small Wendy’s Frosty, and downloadable VUDU movie rental each week. Participants will also be eligible to win bigger prizes such as trips, gift cards, and event tickets.
