T-Mobile logo on store building

T-Mobile is offering a free voice line for both new and existing customers! This deal is available on most plans – more details below.

T-Mobile Free Voice Line Offer

Similar to a deal Sprint customers are getting, T-Mobile is offering new and existing customers a free voice line! The deal will go live starting on June 26, 2020 September 18, 2020 December 20, 2020 in stores and online.

This is absolutely bananas. Personally, I now have 10 voice lines, but only paying for 2 of them. The rest were free from these T-Mobile free line promos!

Ninja Update 12/20/20: Website is not showing promotion, but it’s active. Customers will be able to get a free voice line in store or via T-Force (T-Force is T-Mobile’s social media team on Twitter). You can also call 1-800-937-8997 or text 611 and reference “2020 Line On Us 4”.

New T-Mobile Customers

New T-Mobile customers that activate 2 voice lines will get another voice line for free.

Existing T-Mobile Customers

As long as you have 2 paid voice lines on a qualifying plan, you’re eligible to add another voice line for free.

What’s a voice line?

T-Mobile, like other carriers, offers different types of lines:

  • Voice lines: phone with a number and an associated mobile data plan (this is what this promo offers – you’re adding a line to your account that gets the same features of your account plan)
  • Mobile Internet lines: tablets and hotspots used for internet (no phone number associated with the service)
  • Wearable lines: smart watches with data capabilities (no phone number associated with the service)

The other stipulation is if you’ve canceled a line in your account in the past 90 days, you won’t be eligible.

Qualifying Plans

All qualifying plans aren’t clear at this time, but we do know that qualifying voice plans confirmed as eligible for this offer are:

  • Simple Choice
  • Magenta
  • Magenta Plus
  • Magenta Amplified Family Plan
  • Essentials
  • One
  • One Plus
  • One Amplified Family Plan

  • Military
  • First Responder
  • 55+

Stackable With Other T-Mobile Deals

What makes this free voice line a very hot deal is the fact that you’re able to combine this with other T-Mobile offers!

For example, you can stack this with select phone deals.

Free Phone Offers

Currently on their web site, T-Mobile is offering a free Google Pixel 4a 5G through billing credits when you add a line (which you’re already doing for free with this deal) and trade in an eligible device.

50% Phone Deals

T-Mobile also has a limited-time offer of 50% off an Apple iPhone XS when you add a line. The strategy for them here is to get additional revenue through your monthly service to offset the money they lost from giving you an iPhone for half its retail price.

Well, with the free voice line deal, you’re making out big!

You’re adding the line free and getting an expensive iPhone model for 50% off!

T-Mobile 50% off iPhone XS promotion

Ninja Note: This free line deal will not stack with the following phone promotions:

  • iPhone 12 “on us” (2020 Apple Trade Activate P3)
  • BOGO iPhone (2020 Apple Buy 2 P11)
  • Free Galaxy A71 5G with new line (2020 Samsung Activate P12)
  • Free OnePlus 8/8T+ 5G with new line (2020 OnePlus Activate P5)
  • Any bring your own device (BYOD) promos from Costco

Do not attempt to get one of the ineligible phone promos with the free line. The system will default to giving you the phone promo instead of the free line and you’ll be stuck with a regular paid line. To clarify, if you purchase a phone on EIP on the free line that would normally qualify you for a phone promo listed above, it will force the phone promo over the free line. This basically prevents you from adding any of the phones above to the free line.

$250 Bring Your Own Device (BYOD) Deals

This one is aimed specifically for Verizon and AT&T subscribers. If you port your number and use your existing phone, T-Mobile will pay you an additional $250!

Technically, you don’t even need to be a Verizon or AT&T customer either. As long as you have a phone you currently don’t use with T-Mobile, you can basically buy a Verizon/AT&T number to port in.

The latest promo code for this is “2020BYOD1” (valid between 9/18/20 – 10/1/20). For more details, you can check our post on this.

The Bottom Line

This is an extremely rare no-stipulation free line (like the free line offered back in 2016).

There have been promotions like this in the past, but T-Mobile usually requires existing customers to add a new paid voice line in order to get one free. This offer is much more generous. It is truly free if you are eligible. Keep in mind you still need to pay government-imposed taxes on the free line, but it only comes out to a few dollars a month.

There’s a great FAQ of this deal on Reddit if you want to see more information on how others are taking advantage of this deal.

  1. Jumped on this deal and got the $100 port a line rebate from buying an ATT sim card on ebay. Rebate status shows processing. Thanks TMN!
