FAQs

Customers shouldn't cancel an existing line with the intention of replacing it with a newly activated line to take advantage of this promo, even if the cancellation happens after the new line activation.

Customers should never be told to cancel lines, before or after a promotion, in an effort to qualify or justify a promotion. If customers do not need additional lines, explore other promotions or discuss device price points. Driving CHURN to close sales is not the right thing to do.

There are two different Costco port-in rebate offers, each designed for a specific customer scenario:

  • One for customers who want a new device on Experience Beyond.
  • One for customers who are bringing their own device (BYOD) on Experience Beyond or any other eligible rate plan.

Because each offer has different rebate submission steps, submitting the wrong rebate can create a poor customer experience. Be sure to recommend the correct offer up front and provide the right redemption steps so the customer can successfully redeem their rebate.

Both offers must be submitted via the promotions.t-mobile.com and will require two separate submissions. For additional details around Keep and Switch: Visit Switcher Programs.

Pro Tip! Submit Keep & Switch first, then submit the Port-in Rebate.
