If a customer cancelled their phone plan or lines before receiving the card or completing the installment timeline, the remaining balance on both devices became due in full immediately. 🛠 Strategic Exploits by Consumers

Buyers discovered they could combine T-Mobile's corporate BOGO with external retailer gift card promos (such as activations done at big-box stores like Target), pulling in hundreds of extra dollars in secondary rebates.

New customers had to open at least two lines of service, while existing customers were required to add at least one entirely new line to their account.

The lines had to be activated on a premium unlimited high-speed data tier, such as the T-Mobile ONE Plan or Simple Choice Unlimited.

T-Mobile offered several highly publicized "Buy One, Get One" (BOGO) promotions for the Samsung Galaxy S8 Go to product viewer dialog for this item.

T-Mobile did not hand over the cash immediately. Buyers had to pay the active monthly financed cost for both phones on their bill for roughly 6 to 8 weeks before the rebate arrived.
