The best T-Mobile deals of March 2025
Published onMarch 4, 2025
T-Mobile is the third-largest wireless carrier in the United States, and its popularity is largely due to its network coverage and the wide range of tempting offers available. These range from T-Mobile phone deals for existing customers to trade-in deals for new customers and everything in between.
Below, you’ll find the best T-Mobile promotions currently available. Perhaps something in there can save you some money when you make your next smartphone, tablet, or smartwatch purchase. We’ll be sure to keep this page updated regularly with new T-Mobile deals as they become available.
The best T-Mobile deals
Editor’s note: We will regularly update this list of the best T-Mobile deals as new promotions go live.
1. Get up to $1,000 off the Samsung Galaxy S25 range
T-Mobile has some of the best deals on the Samsung Galaxy S25 series. There are a range of promotions, depending on whether you’re trading in your old phone, whether you’re a new or existing customer, and which plan you’re on. The summary is that you can save as much as $1,000 if you’re switching up your old device or around $800 if you’re just adding a new line.
For those adding a new line of service on the Go5G Plus or Go5G Next plans, you’ll get $800 off the latest Samsung flagships. That could land you the base model Galaxy S25 for free.
If you’re an existing customer on one of those plans, trading in your old device can get you that same credit of $1,000. This sounds fairly standard, but the old device you switch can be one of several eligible devices and can be in any condition.
Other deals for adding various new lines or trade-ins outside the plans referenced above can also save you money on the hot new Galaxy handsets. Hit the button below to peruse them for yourself.
2. Get a free iPhone 16 Pro with trade
The latest Apple flagship was one of the most hotly anticipated devices of 2024, and the iPhone 16 certainly lived up to the hype. This month, customers on the Go5G Next plan who trade in their old device can save up to $1,000 on the range, meaning you can get the iPhone 16 Pro free of charge.
Customers on a lower plan can save up to $830 on the range by trading in their old devices, but the deals don’t stop there. Nine promotions are available, depending on whether you’re a new or existing customer, the device you have to trade, the plan you want, and so on.
T-Mobile is also offering the new iPhone 16e for free to most customers activating a new line or in exchange for a trade-in to existing customers.
3. Get $1,000 off the Google Pixel 9 Pro XL without a trade
The latest Google devices are some of the finest near-stock Android phones you can buy, and you can save up to $1,000 on the Pixel 9 series without a trade-in. That means the Pixel 9 is free, while the 9 Pro, 9 Pro XL, and 9 Pro Fold become a whole lot more affordable.
The caveat to getting the deal is adding a new line on the Go5G Next or Go5G Plus with a 24-month contract. If you’re an existing customer who doesn’t need a new line, you can make the same savings by trading in your current device.
For those who don’t want to commit to such a lavish plan, other plans can drop the price of the Google handsets by $600, or just trading in your old phone can still knock $500 off the new Pixel devices.
4. Save $800 on the Galaxy Z Fold 6 or Z Flip 6 without a trade
The Samsung Galaxy Z Flip 6 and Z Fold 6 are the kings of the foldable market, and T-Mobile has some sweet deals available for the devices. While many other carriers and retailers require you to trade in your old phone to get substantial discounts on the hotly anticipated foldables, T-Mobile will drop the price by up to $800 just for adding a new line of service.
Given the retail price, this discount in the form of bill credits allows you to pick up the Galaxy Z Flip 6 for $299.99. The remaining balance to pay on the Galaxy Z Fold 6 drops to $1,099.99. New customers can score this amazing deal by adding a new line on the Go5G Plus or Go5G Next plan. You’ll then receive your $800 rebate over the 24-month contractual period.
Existing customers on these plans can save even more but will need to trade in their current device. If you’re upgrading to one of these stunning new devices, you’re unlikely to need your old phone anymore. Switching up for the new foldable can score you as much as $1,000 off the devices.

5. Try T-Mobile for free for three months (new customers)
T-Mobile is taking advantage of the eSIM revolution to bring you an extraordinary offer. The company has a flagship feature called Network Pass that, impressively, gives you free T-Mobile service for three months. That’s unlimited service, too, with no data caps outside of the usual 50GB throttling limit. Far from being a bare-bones trial, you also have temporary access to certain Magenta Status benefits, such as travel and T-Mobile Tuesdays perks.
There’s no obvious catch to this deal — T-Mobile wants to convince you to switch. You can try the service without leaving your current provider, and there are plenty of incentives to be found on this page if you decide to do so.

6. Get a phone for free when you switch (new customers)
You can get most of the top flagship phones at substantial discounts, but T-Mobile can also hook you up with a free phone just for signing up for a new line of service. This deal covers plenty of OEMs, and the choice is yours.
All you have to do is activate a new line, and you’ll get 24 bill credits to chip away at your bill. Unlike some of the offers above, this can be a new line on any plan. Check out more of the T-Mobile free phone options below:
7. T-Mobile smartwatch deals
T-Mobile is currently offering various deals that’ll help you add a smartwatch to your wearable tech collection. If you like the look of the Samsung Galaxy Watch 7, you can get it for free with a new line of service.
If Samsung isn’t your ecosystem, you can save $380 on the Google Pixel Watch 3, with some Apple wearables also on offer. As usual, you need to buy the first device through installments over 24 months, and T-Mobile will give you credit over that period.
Check out the details using the button below.
8. T-Mobile tablet deals
T-Mobile has a ton of great phones on offer, but there are some tablet deals, too. Like the phone deals, some tablets are far cheaper if you activate a new line of service, and T-Mobile is offering great deals on top tablets, such as 50% off the Samsung Galaxy Tab S10 Plus with a new line, free cellular upgrades on the latest Apple iPad range, and more.
Hit the button below to check out which tablets are currently on offer.
9. Get Apple TV Plus for free
The Apple TV Plus subscription can also be shared between up to five people, which makes for a great addition to using the world’s largest and fastest 5G network. If you choose the Go5G plan, you’ll get six months of the service for free. Hit the button below for more details on this offer.
If Apple TV Plus isn’t your thing, there are also similar offers available on Netflix and Hulu ad-supported plans.
10. Switch to T-Mobile and get up to $800 back
T-Mobile is offering extra incentives to help you make the switch from another carrier to T-Mobile. Currently, you can keep your phone and pay no additional costs when you switch from another carrier to T-Mobile.
This deal also includes up to $800 in the form of a virtual prepaid card to help you pay off any costs that may come with changing carriers. If you’re looking to switch carriers, click on the link below to find out more details.
11. Other options on the T-Mobile network
If you’re looking for a great deal on the T-Mobile network that doesn’t necessarily have the T-Mobile name, you can also consider looking into an MVNO. An MVNO (Mobile Virtual Network Operator) is a third-party carrier that relies on a major network for coverage. Here are a few of the T-Mobile-based MVNOs that we recommend:
- Mint Mobile: The MVNO is headed up by Ryan Reynolds. Choose your plan here.
- Tracfone: One of the longest-standing MVNOs. Pick a plan here.
- Metro by T-Mobile: Formerly MetroPCS. Check out the plans here.
Those are all of the best T-Mobile deals at the moment. Stay tuned as we will update this page with more deals as they are announced.
