The LG Wing comes in two colors: Illusion Sky and Aurora Gray.

New Customer Deals

Get the Essentials 3rd Line Free

The Deets: Must activate at least three new service lines. Limited time offer.

Aside from free smartphone deals, new T-Mobile customers have the chance to get a free service line. The Essentials 3rd Line Free promotion basically lets you get the third line for free, which you’ll receive via monthly bill credits, when you activate at least two new lines. Paid phone lines must be active to continue receiving credits, and you must activate all the lines within the promotional period. The Essentials unlimited plan costs $26 per line for four lines; this rate doesn’t include taxes and fees. You’ll save up to 30% off your plan compared to other competitive mobile service providers. Under the Essentials plan, you get unlimited talk, text, and data, 5G connectivity at no extra cost, best-in-wireless scam protection, unlimited texting abroad, SD streaming, and more.

Existing Customer Deals

Add Two New Lines and Get One Free

The Deets: Must have an existing eligible plan and add two new service lines. See full terms for excluded accounts/plans.

If you’ve been with T-Mobile for a while, you’re probably wondering when you’ll be presented with exclusive offers for being loyal. Well, your prayers have been heard — add two new lines to your current (eligible) plan and get the third one for free! What’s great about this deal is that you can stack this with the Essentials 3rd Line Free promotion, which is available for both new and existing customers. So for single line customers, they must add four new lines to get the third and fifth lines for free. While this offer has some strings attached, it benefits large households. Even if you don’t live in a large household, you can add your friends or family members to the plan and just have them pay their monthly bills separately. One or two people will get to enjoy the free line, which could be you, so it’s a great deal for expanding your plan.

Upgrade Deals

Lease a Device for Zero to Little Down With Low Monthly Payments Through JUMP! On Demand

The Deets: Devices must be returned in good condition. Limited time offer.

Not committed to a smartphone? JUMP! On Demand allows you to upgrade your leased devices every 30 days. You must lease a device for 18 months; models with increased memory space or premium features may require a larger upfront payment. When you do want to upgrade, just bring in your leased device, have it inspected, and swap it with a new device once approved. New and postpaid customers are eligible for JUMP! On Demand. You’ll pay off the device in nine payments (no interest), and at the end of your term, you’ll pay the remaining balance. Once paid, just give the device back to T-Mobile and make sure that it’s in good condition. When you choose from select top brands, you get $100 back no matter your credit score. From an iPhone SE to a Samsung Galaxy A11, the options laid out for you.

Expired T-Mobile Deals

Buy a Samsung Galaxy S10 or Note10, Get One Free

The Deets: Must activate a new service line on an eligible plan and buy one device on a monthly payment plan.

While this deal is no longer available, T-Mobile is currently offering similar deals for newer Samsung Galaxy models like the Samsung Galaxy S21 5G. New and existing customers qualified for the deal; they simply needed to activate a new qualifying service line on an eligible plan and pay over the course of 24 months for the smartphone device. The Samsung Galaxy S10 comes in five colors: Prism White, Prism Black, Prism Green, Ceramic White, and Ceramic Black. It comes with multiple cameras and records in UHD 4K. ROM size is 512 GB, which is plenty of storage for heavy app users. More of a tablet person? The Note10 is fast and offers the same amount of storage as a laptop’s at 256 GB. If you bought a S10, you could get the Note10 for free under this deal.

Switch and Get up to $700 off on an iPhone 11

The Deets: Must join T-Mobile, activate a new service line on an eligible plan, buy an iPhone 11 on a monthly plan, and get up to $700 back via 24 monthly bill credits.

As each year gives us newer iPhone models, we bid the older ones farewell and never look back. The same can be said with T-Mobile’s offers on iPhones; customers want the newer models, so the iPhone 11 has become irrelevant compared to the iPhone 12 and beyond. That’s not to say this deal has completely gone away; now, it’s up to $300 off or buy one, get one free. New customers had to switch from a different mobile provider to T-Mobile, open up a new line on an eligible plan, and buy any version of the iPhone 11 on a monthly payment plan before getting up to $700 back in 24 monthly bill credits. To qualify for the free iPhone 11, new customers needed to open up at least two eligible lines. These requirements still apply for the amended deal, but the value of the iPhone 11 has decreased, so it’s no surprise that the deal itself has changed to a lower savings amount too.
