Free line requires 2+ existing lines. New customers or existing customers with one line have different requirements. Does NOT stack with Costco or T-Mobile rebates.

https://www.reddit.com/r/tmobile/...free_line/

From Reddit:
Customers on an eligible plan (list below) with 2 or more paid voice lines can add another voice line for free via monthly bill credits. Business plans are included. Customers must not already be at their rate plan's maximum number of lines. Business customers must have less than 12 lines to qualify.

You must maintain all the lines you have now + the free one for 12 months to keep the free line credits. After that, you must maintain at least 2 paid lines + this free line to keep the bill credits.

This promo will actively take priority over the current Third Line Free promo. This means new accounts adding 3 lines or existing accounts with 1 line adding 2 lines will receive this promo, not third line free, meaning they will not stack unless you already had third line free to begin with.

The free line stacks with phone promos currently available, as well as Carrier Freedom/Keep and Switch/Zero Cost to Switch. It does not stack with Costco or T-Mobile rebate promos.

BOGO for T-Mobile ends 3/16 - https://slickdeals.net/f/14878039-t-mobile-2021-buy-one-get-one-voice-add-a-line-for-existing-customers-ymmw

20% Hookup - https://www.reddit.com/r/tmobile/..._17th_for/ - This is YMMV for targeted Home Internet & Connected Device customers.

From Reddit:
Starting March 17th the Insider Hookup will return for existing T-Mobile customers that have Home Internet or Connected Devices with no voice lines.

This promo will allow you to port in from your existing carrier and get 20% off all voice lines for the lifetime of the account.

To clarify: The only people eligible for this upcoming Insider Hookup are Existing T-Mobile customers that do NOT already have voice lines at all. You must have Home Internet from T-Mobile or a connected device like a tablet or hotspot, but you can not already have voice lines.

QA note: YMMV https://www.t-mobile.com/offers/deals-hub

TODAY IS THE LAST DAY FOR THIS PROMO AS WELL AS THE IPHONE PROMOS.
If you are using a phone promo on the free line that requires a port in, you MUST complete the port in by end of day TODAY, March 23rd.

T-Mobile has updated the SOC list again to revert it back to an earlier version. It now includes more SOCs. The SOC image in the main post has been updated. -- Jman100

To find your SOC code for your rate plan, you can call CS 611 and ask, or figure it out yourself:
  1. Install the Chrome extension: https://chrome.google.com/webstor...ldjhocmmpl
  2. Add the Firefox extension: https://addons.mozilla.org/en-US/...mo-helper/
  3. Go old school and sift through the web code: https://www.reddit.com/r/tmobile/...soc_codes/

Quote from ouloat :
For anyone looking to buy a iPhone 8 for the trade-in requirement for Tmobile's iPhone 12, the following are the different sources ranked from best to worst. Keep in mind the phone carrier doesn't matter for the trade-in, so it can be unlocked, AT&T, Verizon, T-mobile, anything. Phone must not have water damage, cracked screen, anything that could be perceived as a cracked screen, password lock, or icloud lock. Small dents, scratches, screen burn, and weak batteries are okay.

Trademore - iPhone 8 starting at $159 [trademore.com]
Folks in the Cricket iPhone SE thread been trading their iPhone SE's for $200 Paypal from Trademore, so we know they are legit. They are also the trade-in inspector one of the cell carriers (Verizon or AT&T), so doubt they will sell anything that doesn't pass inspection. They will probably be your safest bet to acquire a good quality trade-in. Shipping is included in the price.

Swappa - iPhone 8 starting at $158 [swappa.com]
Swappa's policy is no junk, so you are covered if you receive something you can't trade in. That said, since everyone is a third party, you get a wide variety of prices and conditions. I have received cracked screens before, but the seller took it back immediately. Still, this may cause you to lose this Tmobile promotion. Shipping is included in the price.

Local (Craigslist, Offerup, etc)
Your experience will vary, and the onus is on you to validate the phone is ready for trade-in. You might score with a great deal, or you might get ripped off. Only go this route if you know how to inspect phones or you need the phone the same day.

eBay [ebay.com]
You will have to read each listing very carefully, since there are listings for cracked, water damaged, icloud locked, or otherwise untradeable phones. Returns policies also vary by seller. Unless you score an amazing deal on ebay, Trademore or Swappa are safer options.

Your comment cannot be blank.

Featured Comments

If you remove any paid lines within the first year, the free line loses the promo and becomes paid.

TMO doesn't want people doing what you're wanting to do.

To accomplish it, you would need to:

1. Add free line.
2. Wait a year + one day.
3. Port out paid line to another carrier.
4. Keep paid line active on another carrier for 90 days (to preserve number).
5. Port old number back in on free line.

This whole process has taken you 1.25 years. Peace
My port-in was initiated during T439 promo period and completed today outside of the promo period. Without the port in (with only the added line and traded-in) I was on a bad promo. Once the port-in completed today, the system auto updated to T439 promo in my account --> promotions. Therefore, I don't think it was a requirement the port-ins must be completed by 3/24 EOB, just as long as they are initiated.
YES, you can use this sim in your iPad. I pay for 2 lines and have 3 free lines on promotion (5 lines total)
I have 2 of my free lines in a iPad and a Samsung S4 tablet, with UNLIMITED data.
You have to call them and tell them you want to use the line (promo line) in a tablet but don't want to lose the promotion and you don't want to open a new line for this.
What they did for me, was block the phone service on the line and kept the messaging and data. That way I am able to use it in my tablet.
Every summer my daughter comes and visit from Germany. I take one of the sim card out of my tablet and put it in her phone..
I call T-Mobile and have them unblock the phone service. That way, my daughter has a phone while she is here in country.
When she leaves I call them back and get it blocked again. I have been doing this for close to 5 years. So I know for a fact it works.
Tomorrow I will be calling to try and get another free line.. (Fingers Crossed)
Hope this helps

I am in bit of an impasse and wanted to see what you guys think should be done. The T-Force and T-Mobile chat is telling me a big mumbo-jumbo that my SOC Code TIUNL2 is not eligible for the "2021 Line on Us P6" Promo. At least 6 different Agents said so on different platforms. The SOC Code list here and on Reddit clearly has the TIUNL2 on there as an eligible SOC Code for the "2021 Line on Us P6" Promo. What should I do? Is there a new eligible SOC Code list that is, by any chance, not posted here or on Reddit?

Hello all - Just FYI. I strongly probed the T-Force Agent for the complete list of the SOC Codes for the "2021 Line on Us" Promo. There are a lot of SOC Codes that are not on this compared to the one posted here and on Reddit. Here is the chat transcript:
—————————————————
Absolutely, I see no reason why we cannot have full transparency here.
Little "Disclaimer" that these SOC codes are subject to change at any time, however as of writing this, here's the full list of eligible codes:

"Reminder: If a plan's SOC isn't listed in the table below, it is not eligible for the offer.

Boost is Sprint (which is TMobile now) MVNO, so will not work.

Dish now is buying boost from tmobile last year so is not T-Mobile and the rep from t-force said is eligible but I haven't port in yet. Anyone good through?

I was in touch with TForce this morning. I confirmed multiple times that my plan is eligible for the 2021 Line on Us promo that is currently being offered.

The SE really really sucks, even free. I opted for the 12pro 128gb, with the $150 costco GC it's basically free. Traded in an old X that I needed an excuse to get rid of.

You can do port-in once you see the phone number in your account. I did that for a friend of mine and the free Iphone SE promo kicked in after successful port-in. His phone has just shipped, but he is all set with the promos.
Sweet. Thanks for the heads up.

could someone tell me if all your discounted from 8 lines showed up in your account after migrating to 9-12 lines? I just did the change to 9-12 lines and none of my free lines discount showed up in my account. I chat with T-force and they said it won't show up until the billing, is this true. Just want to make sure the migration was done correctly and I do not looses any of my free lines.

I now have 8 lines after adding this one at Costco today. Now I need to go this route also to prepare for the next free lines.

Please read the parent Reddit Post. A bunch of codes got taken off the list at 9P EST - it was just updated after my post. The TIUNL2 and bunch of Amplified plans are part of it. Not sure what happens if you added a line before the SOC Codes got taken off the list.

Ah not what I meant. Meaning sign up for the line today. Then buy iphone 12 + trade in/port promo on Monday
I am told as long as you are porting in during the promo period, you can buy and trade in. So, a few days should work but see if you can add a note to your account that you would be doing so.

You'll probably receive text regarding promotion un-enrolled and congrats for receiving promo discount. That's what happened to mine after going to 9 lines. Probably takes a few hours for the system to do its thing.
