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:
SCFUTTBD: 10 lines

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

You can get the following phones for free with the free line and you do not need to port in a phone number. You do need to pay tax on the normal price of the phone. These phones are currently free with any new line.
Moto G Play
Samsung Galaxy A11
T-mobile Revvl 4
T-mobile Revvl 4+
LG K51
LG Stylo 6
LG Aristo 5

Which is the best one and how do we get it?

Quote from smooth28la :
Did they actually require you to have the physical BYOD phone or would a screenshot of IMEI number be enough?
I think it's ymmv. I have seen in past reps deny and also approve printed copies.

Regarding rebate.. who knows of it would work but no harm in trying .. worst case it gets denied then you call and argue with some useless rep. Yes I have had to do this.

Since the Costco rebate expires today and Costco closes soon I'm debating ..

Thanks. That is my current SOC. I am trying to figure out what is the better SOC (FRLTULFM9 vs TIULFM9) to switch to prepare for future free lines.
Either one should be fine for up to 12 voice lines and 5 MI lines. All my promos and discounts were switched intact.

Quote from frosty :
I am being told that I am maxed out at 8 lines on Tmobile One plan, so they can't add the free line, even though I technically qualify for it. Any idea what the workaround is?
Contact T-force via twitter or facebook and request them to change the plan to TIULFM9 or FRLTULFM9 which will change the plan to 9-12 lines. Make sure that they can move all the promos and discounts.

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)
I think you're the one I saw regarding the 9 line billing thing. You have Tmobile ONE though.
If it works with Magenta, great, no need to cancel the Line 7, since if I get the free 9th line and iPhone SE, it would need 24 months to get full credit for phone.

Anybody submitted the Costco $150 and see whether the expiration date IS today?

You need to port-in a number in order to get $830.

Tax on pre-credit price due at sale. Limited-time offer; subject to change. Qualifying credit & port-in required. If you have cancelled lines in past 90 days, you may need to reactivate them first. $10 SIM card and, in stores & on customer service calls, $20 assisted or upgrade support charge may be required. Up to $399.99 via bill credits; must be active and in good standing to receive credits; allow 2 bill cycles. Max 4 discounted devices/account. May not be combinable with some offers or discounts.

Purchase a new iPhone SE using T-Mobile's Equipment Installment Plan (EIP), activate a line on a qualifying rate plan, and port your number to get the device on us via 24 monthly bill credits.

That's the correct amount $415 for that particular trade in scenario.
The $830 amount requires additional requirement - port in
