If you recommend a friend to join T-Mobile on our SIM only You Fix plan, you and your friend can each get a Booster giving unlimited calls to other T-Mobile customers for 3 months. A fair use policy applies to use of the Booster so if, in the reasonable opinion of T-Mobile, use of unlimited calls is excessive, we may ask for the usage to be reduced. If usage isn't reduced, we reserve the right to remove the Booster. We're afraid that neither of you will get a reward if either of you have given notice to leave T-Mobile.
