If you’re thinking of leaving T-Mobile, think again. It turns out that the company has some secret deals in place to convince you to stay.

According to The Mobile Report, T-Mobile has a promotion called “Stay Magenta” that can only be offered and activated by customer care representatives. This promotion is only available to postpaid customers with at least one voice line. If you qualify, you could receive a $10 discount on your bills for the next 6 months, or a $25 discount for the next 2 months. The catch is that you have to agree to stay with T-Mobile for the duration of the promotional period.

The only way to take advantage of this offer is by contacting a customer care agent, either by phone or through social media. If you’re still unsure about leaving T-Mobile, it might be worth reaching out to see if a discount can change your mind.
