Customers currently under contract with another carrier are eligible for up to $650 per line (up to 5 lines). It’s two simple steps.

1. When porting their number they can trade-in their current phones and tablets at any participating T-Mobile location and receive a credit up to $300 per device, which can be applied towards a new device purchase.

Then, when they get their final bill listing their ETF amounts, they simply send it to T-Mobile or submit it online at switch2tmobile.com, and within 8 weeks they receive a prepaid MasterCard covering their ETF amount up to $350 per line. The amount paid will not be more than the ETF amount the customers’ previous carriers charge for the type of device traded-in.

I have applied for my rebate but have been told I do not qualify because I did not trade in a phone. As you can see from the above paragraph the wording is CAN not MUST. I did everything else ported my number and purchased a new T-Mobile phone. Customer Service apparently does not know the difference between CAN and MUST.
