Heads up, existing T-Mobile subscribers, because today is the last day that some of you can claim your free stock.

Stock Up was announced at the Un-carrier 11 event earlier this month as T-Mo’s effort to give its subscribers free stock in the company. Customers that joined T-Mobile on or before May 28 have until June 21 to claim their free share in the company, meaning that today is the last day that those folks can get their stock. If you joined T-Mobile between May 29 and June 6, your last day to claim your free stock is June 28. New customers must switch to T-Mobile from a postpaid carrier to be eligible for Stock Up, and they’ve got 15 days to claim their share once it appears in the T-Mobile Tuesdays app.

To get your free share, you’ll need to load up the My Stuff section of the T-Mobile Tuesdays app — which is having issues today, but T-Mo says that they’re working on it — to confirm your eligibility. Every primary account holder on postpaid consumer voice accounts are eligible for a share. To actually receive your stock, you’ll also need to sign up for an account at LOYAL3.

Also worth noting is that T-Mo customers can get up to 100 additional T-Mo shares per year by convincing people to switch to T-Mobile. All that you need to do is go to the Stock Up webpage or log in to my.t-mobile.com and enter your friends’ phone numbers. If they accept your referral, switch to T-Mobile, and stay active for at least 15 days, you’ll get an additional T-Mobile share. Customers that’ve been with T-Mobile for five years or more will get two additional shares for each referral.
