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/
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

Oh yeah, I forgot about that. As far as you know, the "BO" part of the "GO" is not married to each other though right? So after 13 months after the last free line, it can be taken out?
Thanks again for the reply.
If it is a BOGO, then both lines have be active to receive the free line credit. If one line is canceled or ported-out, then the free line becomes paid line.

You need to port-in a number in order to get $830.
I do plan to port in a number. Will the system automatically change the amount? Prior to logging into my account, I see the $830 amount with trade in and port in. But after logging in, it only states $415 with trade in and no information about port in.

Quote from i4k20c :
Is there any reason for me to worry?

I started the process march 17 at ~430pm CST and finalized it at ~8pm CST on March 17.

I did the following things: Got a free new line, used the iPhone 12 on us with the new line (port from vzw), and upgrade a current iphone on tmo account to 12 for the $415 trade in.

Whenever i go to click on order status, it just spins and spins on the website. When i click on account history, i am seeing a new line was added and it says $0 but than it enrolled the new line for the 2021 Apple Trade P1 and is only showing a monthly credit of 9.92/month.

I don't even see anything yet about my tmo phone being upgraded to the 12.

It makes me feel like they goofed up and put the $415 credit on the new line, and no idea what is going on with the current line.

I'm unsure whether i need to wait a few days for things to update or panic?
The "2021 Apple Trade P1" should switch to "2021 Apple Switch Trade P1" after the port-in is completed. It took 2-3 hours on my account to switch from one promo to the other. Now it displays the correct promotion and $830 credit over 24 months.

Quote from KingUltra :
You will Not even care to Cancel anything if your Plan becomes close to this after adding your 9th Line Free. (3 paid, 6 free)
Impressive :-)
Need advice from you guys who are in 9-12 lines club. My situation:
Magenta1.0 (MAGENTA2) with 20% hookup, 8 lines:
Lines 1, 2: paid
Line 3: free, 2020 3rd line on us 3
Line 4: free, 2020 Line On Us 2
Lines 5, 6: paid, costco $300 byod deal
Line 7: paid, costco samsung bogo deal
Line 8: paid, costco iphone se deal

As of now, total is $160 ($96+4x$16). I tried to see what TMO would offer if I add a 9th line through my account. It offers me $30x9=$270 Magenta plan, not sure if MAGENTA9 or MGNTA9. Did not take it, lol.

My question: if I change to 9-12 line Magenta plan through chat or TF and manage to keep 20% hookup discount and 2 current free lines, and get new free line, what my new total may look like? Just a rough estimate would be fine (or PM would be appreciated). Thanks!

From what I have been told, if you do everything right, it should work. I personally do not like doing it all online without getting the assurance that I am meeting all the requirements.

Again, in order to get $830 off, you need to meet the following.

- Add a line (Free if you qualify)
- Port a number (Generally speaking, the number needs to be from post paid AT&T or Verizon. Some prepaid numbers might work but hit or miss. My Tracfone # was denied)
- Trade in a qualifying phone

Without the port-in the promo is "2021 Apple Trade P1". With the port-in and trade-in, the promo is "2021 Apple Switch Trade P1" which started on 3/17/21. Tmobile phone page after logging in for some reason doesn't show the new promo, but will work with trade-in and port-in.
When your port-in and trade-in is completed, the "2021 Apple Trade P1" should switch to "2021 Apple Switch Trade P1".
It took 2-3 hours on my account to switch from one promo to the other. Now it displays the correct promotion and $830 credit over 24 months.

I did all transactions in-store - adding free line, port-in, and trade-in. Hence, all my promos were applied the same day including the message that my trade-in was complete.
