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

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

Quote from Indaeyez :
Thank you for responding. I got a break down and besides the taxes and activation fees I'm being that I have to put a down payment down. I've had other new lines on the account and have devices on EIP's and only had to pay the taxes. I asked why is additional fee such as a down payment required and I'm waiting for the rep to come back.
It's going to be due to your credit line being maxed out. Unless the upfront cost is a huge problem it would be best to at least lock in the free line on us before that promo ends and given there may be slow response due to high demand. You can place the phone order a few days, maybe a week later and just DM them to request that Tforce attach the promo to the new phone. They'll probably tell you it's automatically done by the system but they'll make it right if the promo doesn't attach. (I've had all of this happen to me twice recently) Tmobile promos leave people wondering at the time of commitment whether things went correctly because the communication and timing are sloppy so it's best just try get as much documented through DM and trust you can fall back on that documentation if something goes wrong. I've also had it where things go smoothly without intervention but DM doesn't take much effort and is better safe than sorry.

I am looking to add the free line and use $830 off iphone 12 with trade-in.
Currently have 4 lines on Magenta Plus (2 paid and 2 free). SOC is in the list posted.
If I add a 5th line (free) through this promo and get a phone, would it be okay if I use one of the existing numbers in the new device and leave the new number idle without any device?
That shouldn't be a problem.

However, you need to make sure that you purchase/apply the new iPhone 12 to the new line when you order it and port-in a number to the new line as those are the requirements for the promo. Once you get the phone, it doesn't matter which line you use it with.

probably the issue is fixed. I did the B1G1 at Costco from 7 lines to 9 lines. All my Free line On Us promo carried over.
Did you get your SOC changed to 9 line plan by Costco kiosk rep while adding lines? Or got it done through T-Mobile prior to visiting Costco?

I have just finished ordering iPhone 12 (1) with the free line which I added a few days ago, 2) trading in my iPhone XR, and (3) porting-in the Tracfone number from a cheapo HSN LG phone (Verizon network).

The rep I talked to yesterday told me that the Tracfone number did not qualify for the $830 off promo, but the T-force rep I had been communicating told me that it should because the system recognized it as a Verizon number.

The rep I talked to today wasn't sure about the number because Tracfone uses T-mobile as one of their carriers in addition to AT&T and Verizon. She told me it might not qualify for the promo.

I took a chance and went ahead with the process, and the Tracfone number was successfully ported (The phone's IMEI is the account number, which is required for the port in along with the pin code). She told me that it did not necessarily mean that the number was good for the promotion. The system would determine it automatically. I guess only the time will tell. I can at least get $415 for my XR which is not all that bad even if the port-in does not qualify.
I have used the Tracfone number for port-in last time. If it came bundled with phone purchase, it is probably using Verizon service and will work for port-in.

Quote from waterchange :
If the 9th line you're adding is free, your monthly cost will still be $160.

If it's a paid 9th line, your total will be $176. The 9th thru 12th lines are normally +$30 each but one of your existing free lines will automatically take over that $30 slot so your adding $20 - 20% hookup.

If you're looking at it online showing the $270 total, that doesn't include all of your discounts/free lines. $270 - $30 free 9th line - $20 free 8th line - $44 (20% hookup on remaining $220) = $176. Or it's $270 - $30 free 9th line - $20 free 8th line - $20 free 7th line - $40 (20% on remaining $200) = $160.

MAGENTA9 is the original Magenta 1.0 plan and MGNTA9 is the newly announced Magenta plan (5GB hotspot, 100GB priority data). Definitely switch to the new Magenta plan as your free lines and hookup transfer over; there's no downside to the switch.
Hi, you seem to have the math figured out, so I'm hoping you can help. I have a similar question but:
Magenta 1.0 20 % hookup 8 lines:
Line 1 & 2 Paid
Line 3-6 Free
Line 7 &8 Paid $ Free BOGO Costco $300 deal
I belive I'm at $112, and will get the 9th line via AAL. I was told I can't got to MGNTA2 yet since my billing cycle is 26th so maybe it'll be MAGENTA9 first then manually ask to switch to MGNTA9. I was told that upon switching the numbers will be weird until the system settles all the discounts, etc.
Thanks.

It looks that Tracfone uses all the network carriers, and a particular network is assigned to depending on the phone/sim card you get.

Each retail box of Tracfone has an indication which network it uses. My cheapo LG phone from HSN had "LTE-V" (V meaning Verizon) on the back of the box, and the number it was assigned to was with Verizon Network.

I have learned that the T-mobile system only identifies the number based on which network it is with but not based on which MVMO it is with. My case was with Verizon so it should be OK although I am still not 100% confident.

Quote from sussig :
so i chatted with tfroce on twitter and that rep is so quick on the fingers that i simply asked him the differences between TIULFM9 vs FRLTULFM9 and he went and switched me over to TIULFM9 without my permission. then i asked about FF 2 lines on us promo compatibility with FRLTULFM9 and then he switched me over again to that plan without my permission LOL. from my online account, im seeing my hook up, kick back and 4 free lines from last yr are sticking. hook up discount went from $32 to $62 before i even added 9th line.

nevertheless, he was unable to add ff 2 lines on us promo back with FRLTULFM9 even though you said you confirmed couple others had it on their FRLTULFM9 plan. oh well

last thing about google voice # being ineligible. rep also said free google service dont qualify as port in for the iphone deal. however, he checked out the google # i gave him and hes seeing those google voice # as LANDLINE !!! which means landline qualify for the port in. i guess it depends on your google nume whether tmobile seeing them as landline or as voip num

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?

  • Spare - Emergency phone
Tablet use is hit or miss. With my T-mobile Alcatel Joy Tab, the connection get disconnected after a short period of time. I believe that T-mobile system knows that the IMEI is with a tablet and disconnects it. The same sim works with my ZTE K88 Trek 2 (originally AT&T but unlocked), but it gets throttled down to 0.5Mbps. It is usable but slow. I think that more or less the same thing applies to Hotspot use.

Google voice numbers cannot be used to port in and get phone on discount. You will need non Tmobile MVNO to port like cricket, verizon, att etc.

Even if you are able to port in, the promo to get bill credits for phone will drop.
