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.

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/
Maximum (Voice) Lines per SOC code:

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 have Tmobile One with Plus Promo on all lines, hookup, etc (FRLTUL4LP t-mobile SOC code) and 8 lines with 4 being no cost after adding the latest no cost line yesterday at Costco. It was definitely more difficult today getting the reps to add the OnePlus Promo and kickback on the latest free line.

I know that to add more lines i would have to change to a new soc code but of course hesitant since every Tmobile rep is a potential trainwreck. Been reading how the bill drops once you get to 9-12 lines so I am thinking about it but really don't want to go through the hell of trying to correct problems as are sure to happen.

I guess now is the time to research and do so it gives time to correct the issues and be ready for the next free line promo.

What is the best soc code for me since my current one is FRLTUL4LP? I'm thinking about requesting a higher up manager since they have more privs and know the system better if I try this.

Now I am intrigued to do this add a line as people are saying once you get over 8 lines the bill gets reduced? Anyone upgrade to soc that allows more lines without major errors requiring hours to fix with tmobile reps?

Any luck finding answers or changing TM One max 8 to 9-12 plan? I am in same boat with same all promos.

Quote from CalmSoda260 :
I hope this did not create a cluster&^*. Rep changed the SOC code without asking nor confirming and now I don't see any promo lines. Got a few texts that said promotion has ended and then the same number saying I have been enrolled. Ordered a new phone on the new line with port-in and trade in. The temp number hasn't been assigned yet it seems. I provided my own SIM.

I will give it 24/48hours and do some breathing exercises before getting a heart attack... ;-) And a drink. Puh, if this works this all be the last one, too much time involved with this.

From what SOC to what?

Just to report back, the number from my $30 HSN LG Tracfone (on LTE-V - Verizon network) did work for the port-in promotion.

My account is now showing that I have received the 2021 Apple Switch Trade P1 promotion and the monthly credit amount for the next 24 months for the iPhone 12.

If you have Tracfone number with either Verizon or AT&T, it should work. However, if your Tracfone number is with T-mobile or Sprint, probably it won't.

The easiest and sure way is to send a message to T-force through T-mobile Help on Twitter and ask them to check the exact number. Only issue is that the response time is kind of long (can be 1 - 2 hours).

Using a chat through T-mobile app could be another option, but it never worked for me when I tried last couple of days.

Thank you so much for sharing, and your experience. Yes, i have been fighting with them for over 5 months, hope it will resolve (as their last reply that will take care).. but time will tell. worst case i will just cancel that supposed to be free but now paid line.

Repped.
Welcome, if have other free lines, you can only cancel lines which were opened AFTER the free lines. If the paid lines are opened before your free lines, you cannot cancel them until 12 months requirement meets. Otherwise, you'll lose the free lines.

If its non tmobile mvno or non GV it should work, unless the account info is incorrect. Check the port in number at tmobile site for eligibility. Not a guarantee it will work, but good to know tmobile recognizes it for port in.

Switched to new Magenta plan from Essential, $120 all included, 2 Paid Lines and 5 FREE LINES. 👍🏻 Essential Line on Us didn't fall off in a couple days since I switched to Magenta and added a new Free Line so I guess it will be sticked to my account.

Magenta® $120.00/mo
Applied discounts and promotions:
$10 AutoPay Discount
$20 2020 Essentials Line on Us
$25 AutoPay Discount (Additional Lines)
$20 2020 Line On Us 4 (Additional Lines)
$20 2020 Line on Us 3 (Additional Lines)
$20 2020 Line On Us (Additional Lines)
$20 2021 Line on Us 6 (Additional Lines)

They automatically assign you a number when you add a line based on your address.

If you want to port in a number, you can call them and have them change the number, but it's not required.

If you get a free line, you can also get a free Android phone (i.e. Moto G Play) if you want.

Or, you get 50% off on iPhone SE and get it for $200, or free if you port in.
Can you please explain how to get free Moto G, does that require port-in. Thanks in advance.
