Businesses that operate in spaces with a lot of competition have to learn how to keep customers coming to them, and not defecting to other brands. The easiest way to do that is to offer a quality service or product. But, another way to do that is to reward customers for their loyalty.
T-Mobile understands that aspect of Business 101, and is currently offering a deal to some of its existing customers. Trading in a qualifying smartphone (some dating back to 2019) will get you a flat $830 discount on a flagship phone. However, there's one big catch, and that's that you can't be financing any device at that time.
T-Mobile Wants to Keep Existing Customers a Little Longer With an $830 Trade-In Discount

There's so much competition in the mobile carrier space in the US, particularly among the big three. The number of free customers available for the taking is decreasing, and these carriers need to learn how to retain their customer base for longer and attract customers from other carriers to switch sides.
According to The Mobile Report, one of the ways that T-Mobile seems set to do that is by offering some of its loyal customers an exclusive discount of $830 when trading in a qualifying smartphone.

What makes the deal even better is that some of the devices eligible for trade-in are no longer worth nearly that amount, which makes this a deal that you would be foolish not to at least consider. Below are some of the oldest eligible devices, which means newer flagships from the same brands will almost certainly qualify:
| Brand | Model | Launch Year |
| Samsung | Galaxy S10 | 2019 |
| Pixel 6 | 2021 | |
| OnePlus | OnePlus 9 Pro | 2021 |
| Apple | iPhone 11 | 2019 |
The discount will be paid off on a brand-new smartphone of your choice over a two-year period, which is a clever way for the company to lock you in for an extra two years (especially since the offer already targets “untethered” customers, but more on that below).
What Are the Criteria to Take Advantage of This Loyalty Offer?

Before you get too excited about this, it's important for you to know there are certain criteria you'll need to fulfill. However, even among people who tick every box, T-Mobile will likely only be opening this discount to a select population of them. It's not clear what the criteria are for that part of the selection process.
- You must have no Equipment Installment Plans (EIPs) active on your account. In other words, you must not be financing any devices at the time.
- You must have a qualifying device to trade in, though an exhaustive list is not currently available.
- The $830 discount will be applied towards a new phone and paid over two years.
This loyalty discount will be available on any T-Mobile plan, so that's good news if you're on some obscure legacy plan. The deal will need to be redeemed via the T-Life app, and that will serve as the easiest way to see if you're eligible for this. Alternatively, T-Mobile store reps will also be able to check your eligibility for you.
