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

He will be at $96 for 8 lines magenta or $112 for 8 lines Max and 40gb hotspot per line

And do You do realize that once the guy you replied to adds this promo, and one more line, even a paid line, and switches to magenta 9 line his monthly bill will be only $66 for all those 9 lines. . or $88 if he chooses to upgrade to Max an 40gb hotspot per line?
I have seen people mention that prices go down when you get to 9 lines. How does that work? I'm at 8 lines now (4 paid and 4 free). I was planning on cancelling a BOGO pair in a year to reduce the overall price as I don't need those lines. As part of that plan, I was not planning on taking advantage of any future AAL offers until 2022, but if the price will go down if/when I add a 9th line, I would reconsider.

I'm expecting that my price would remain the same ($128 for the 4 paid lines with the Insider discount) if I add a future free line as the 9th line. Is that not the case? Or is the pricing that different with the MAGENTA9 SOC?

Can you provide the freedompop port out procedure?
Just a quick heads up about FreedomPop port-in !
I have been told twice by the T-Force people that FreedomPop is not eligible since it uses both AT&T and Sprint (which is T-Mo family) which makes it ineligible for port-in promo !
I have 2 FreedomPop #s so wanted to port those in !

idon't know how much time you spend in mexico or canada. . .but for me last 10 years average only 2 days or s a year. i would rather bank $56 a month more and have the extra lines to save my folks $70 every month plus my single brother $56 a month.
This is the part I wonder about. When I use th compare plan tool from the account and select Max to compare it to, the price "including all promos and discounts" jumps $300 per month!!! How can we be confident about upgrading to Max and the bill only going up ~$20-30 per month? I would love to be able to confirm this on my own without recruiting customer service...

I saw the same but didn't complete the order as I didn't see anything mention about free line, is this normal that we don't see this being free? Just wondering how many ordered online vs call in.
NVM, looks like it cannot be done online, has to be via CS rep.

I am not sure but I think #1 is under deals at the website itself. #2 is not yet updated on the site, but CS reps seems to communicate about it as if it is real and accurate.

Just a heads up. Make sure you carefully read the promo they enroll you in-store for the free iphone SE. I asked multiple times and showed the reps the promo I was asking for and they said ok.
I just happen to think about the promo name and it wasn't the free iphone promo. About to contact tforce about this BS, hopefully they can fix it.

Quote from me4tux :
Hi, Since you moved from Magenta 1.0 to Magenta 2.0, can you pls check something?

Under "Manage Data and Add-ons" for your Magenta 2.0 plan, do you still have the options to choose Netflix HD for $5.00/mo and Netflix UHD for $9.00/mo ?
These options are selectable/deletable on a per month basis on 1.0. Some months, I binge on Netflix and would pay the $9.00 for UHD quality just for that month, and then revert back to the free Netflix SD included free on Magenta 1.0

Also, since Magenta 2.0 increases the Hotspot to 5GB, is there any pay option that you can see in Magenta 2.0 "manage Data and Add-ons" to choose more Hotspot data?
In the case of Magenta 1.0 which includes the 3GB hotspot per line, there is an option to pay 10GB Hotspot for $10.00/mo. Again, like the 10GB hotspot option is selectable/deletable on a per month basis.

Thanks!
There is an option for Netflix Standard ($5) and Netflix Premium ($9).
Hotspot options: 15GB hotspot for $10/mo and 40GB hotspot for $15/mo.

I did this today in-store, added a free line, port-in a number from freedompop, and trade-in an Iphone XR. All promos were applied to the account a few hours later.

This was the fastest trade-in that I have done and received a message that the trade-in is completed - all on the same day.
what is the cost for iphone 12 Pro max with this deal?

I have 8 lines now. What happens if I upgrade my T-Mobile One account to a T-mobile One SOC for 9-12 lines by adding this free line, but in the future decide to cancel a line and it drops me back to 8 lines? Does it roll back to my old T-Mobile SOC, or will they automatically enroll me into a Magenta Plan?
In the past, when I port out my # 9 line, my SOC the same. So 7,8 or 9 Lines I was paying the same price every month.
