Best T-Mobile deals

Editor’s note: We will be updating this list of the best T-Mobile deals regularly as new promotions go live.


1. BOGO on Samsung Galaxy devices

This is one of those very straightforward T-Mobile deals: buy a Galaxy device, add a new line to your account, and get a second Galaxy device added to the second line for free.

This deal applies to new purchases of the following devices:

If you don’t want that second device you can simply get a discount added to your next 24 bill cycles equivalent to what you would have paid for the second device (you will still need that second line, though). In the case of the Galaxy Note 10 Plus, that would be $1,200. Not bad!


2. Save up to $300 off OnePlus 7T Pro 5G with trade-in

Looking to jump into the world of 5G? Although you could spring for the Samsung Galaxy Note 10 Plus 5G (and pay a pretty penny for it), the cheapest way to get 5G service on T-Mobile is to use the OnePlus 7T Pro 5G McLaren Edition. This is a T-Mobile-exclusive device here in the United States and the phone starts at just $900.

However, you can save up to $300 off that list price if you trade in an eligible smartphone at point of purchase. You can see the full list of eligible devices here, but here are a few examples:

  • iPhone X, iPhone 8 or 8 Plus
  • Samsung Galaxy S9 or S9 Plus
  • Any device in the Google Pixel 3 or Pixel 3a lineup
  • OnePlus 7 Pro

Additionally, you can trade in some other devices for less of a discount. Check the full list for more info.


3. Open a new line, get a free phone

T Mobile Deals Free Smartphones

This is a great deal regardless if you are a new T-Mobile customer or an existing subscriber. The deal is simple: add a second line to a qualifying plan and get a free smartphone to add to that new line. This is one of the best T-Mobile deals available!

As of right now, these are the phones you can choose from for free:

To qualify for this promotion, you’ll need to either already have or start a Magenta or Essentials line and then add a second Essentials or Magenta line to that same account. The price of the free phone will get charged to your account monthly over the next 24 months, but a bill credit each month will cancel out that charge. If you leave T-Mobile before the full 24 months have elapsed, you will be responsible for paying the balance of the device.


4. Buy one LG G8 ThinQ, get a second free

This is one of the very few T-Mobile deals that does not require you to add a new line. Simply walk into a T-Mobile store, buy a new LG G8 ThinQ and add it to a line on your account, and get that second LG G8 ThinQ for free. You don’t even need to add the second device to your account, you can do whatever you like with it.

Of course, the free phone will be paid off via 24 monthly bill credits, but the fact that you don’t need to add a line to get this deal is awesome.


5. Add a line and then get an extra line for free

T Mobile Add A Line Get A Line

If you are looking to add a new line to your account, you are in luck. The collection of current T-Mobile deals includes an offer that gets you an extra line whenever you add a new line to your account.

That means if you’re currently a single user and add a second line, you’ll get a third for free. If you already have two lines and add a third, you get a fourth for free. It just goes on like that!

This deal is not only open to new customers but also to current customers. Get it while you can!


6. Buy one Samsung Galaxy Watch, get a second free

This deal makes for the perfect dual gift: one for you and one for a loved one. The way this works is that you need to buy a Samsung Galaxy Watch or Galaxy Watch Active 2 and add a T-Mobile Digits line to that watch. Once you do that, you can get a second Galaxy Watch of equal or lesser value — but you’ll also need to add Digits service to that watch as well.

The free watch will be paid off via monthly bill credits and if you cancel either of the Digits lines before full payment is received, you’ll be on the hook for the remaining balance. This deal likely only applies to certain situations, but if you and a loved one on your account both want some brand new LTE-connected smartwatches, this will work out really well for you.


7. Save up to 50% off Galaxy Note 10 Plus 5G with trade-in

Save up to half off Galaxy Note 10 Plus 5G T Mobile

There’s a BOGO deal higher up on this page for Samsung devices, including the Samsung Galaxy Note 10 Plus 5G. However, if you have an eligible device to trade-in and want to spend as little money as possible, this is the better deal for you.

If you trade in an eligible smartphone at your point-of-purchase for the Note 10 Plus 5G, you can save up to $650 off the list price — which is equivalent to a 50% discount.

You can see the full list of eligible devices if you like, but here are some highlights:

  • Any iPhone from the iPhone 8 or later
  • Any device in the Galaxy S9, Galaxy S10, Galaxy Note 9, or Galaxy Note 10 lines
  • OnePlus 7 Pro
  • LG G8 ThinQ

Your rebate for the trade-in will come via bill credits as well as a pre-paid Mastercard that you’ll need to use within six months. The fine print is here.


7. Get a free Samsung Galaxy Tab A

T Mobile Deals Galaxy Tab A 8 inch

This is a very straightforward deal: just add a mobile internet line to your existing account and get a free Samsung Galaxy Tab A 8-inch tablet. That’s it! Yeah, the tablet will be paid off via the usual 24 monthly bill credits so you’re locked into paying for that mobile internet line for two years, but hey: if you need an LTE-connected tablet, you would have had to pay for that line anyway. Why not get the actual tablet itself for free?


8. Get 50% off a Samsung Galaxy Tab S6

If you like the free tablet deal above but don’t like the idea of being stuck with a small-ish tablet from a few years ago, then this is the deal for you. Once again, all you need to do is add a qualifying mobile internet line to your account and you can get the 2019 Samsung Galaxy Tab S6 for 50% less than the list price (currently $725).

The Galaxy Tab S6 is hands-down the best Android tablet on the market today, so this deal is pretty awesome. Once again, you’re stuck on that mobile internet plan for the next two years but you’d be paying for it anyway if you added an LTE tablet to your account, so that’s not a big deal.


9. Save $200 on the T-Mobile Revvlry Plus

T Mobile Deals Revvlry Plus

If you add a new line to your account, you can get the T-Mobile Revvlry smartphone for free. However, if you want to step it up from the regular Revvlry to something more substantial, you can instead save $200 on the T-Mobile Revvlry Plus.

The Revvlry Plus is a significant step up over the Revvlry. It comes with a huge 6.2-inch FHD+ display, dual rear cameras with OIS, 4GB of RAM, 128GB of internal storage, and a decent 3,000mAh battery.

This device’s list price is just $350, so saving $200 is nearly a 58% discount. This is one of the best T-Mobile deals available!

As usual, the remaining price of the phone will get added to your account in monthly installments over 24 months. Avoid leaving T-Mobile during that time or you’ll need to pay off the balance.


Those are all the T-Mobile deals we know of at the moment. Stay tuned as we will update this page with more deals as they are announced.
