The Insider Hookup promotion is also applicable to new T-Mobile for Business customers on the Business Unlimited Ultimate plan. Friends and family who are business owners can also enjoy the promotion.

Original story as follows:

T-Mobile’s Insider Hookup promotion is getting revamped once again. And as reported by The T-Mo Report, the Un-carrier will be offering new and existing Magenta MAX customers a discount of 20% on their accounts for life.

The information shared comes from leaked internal documents obtained by the publication. The document reveals that employees will be receiving 2 codes on January 6th. These codes will be for existing Magenta MAX customers (and those interested to switch), and also for new customers. 

In addition to the 20% off for life offer, customers can combine it with any of the phone promos that the Un-carrier is offering.

True to its name, the promotion is intended for the family and friends of T-Mo’s employees. If you are a customer who wishes to enjoy the promotion too, you will need to find an employee who can share the promo code with you.
