T-Mobile customers, do not miss the free line promo


Update 12/22/20: This deal is back again and valid through 12/24/20. Read more here: Another free T-Mobile line for many customers.

T-Mobile has recently offering a pretty terrific promotion to get a completely free line added to your plan. You might be saying “But I don’t need another line”. Hear me out: if you’re on T-Mobile, I’m willing to bet that you probably would benefit from a new line — in some cases to the tune of an easy $300 in your pocket. You may even get a free 5G phone on top. If that sounds too good to be true, you need to read on at least through the first couple of steps. At some point, the deal will get extra complex. Don’t worry, I’ll tell you when to quit reading if you just want to take the easy money and run.

Adding a totally free line to your T-Mobile account

T-Mobile logo

I believe this is the third time this year that T-Mobile has offered a completely free additional phone line. I should note at the outset that not all plans are eligible for the free line. However, many (including many no-longer-available plans) are eligible.

Determining your eligibility on your own is slightly complicated. If you want to do this the “easy” way, reach out to T-Mobile on Twitter or via the chat function in the T-Mobile app. If you’re OK at following directions/pictures, this reddit thread tells you how to find your plan’s SOC code and this image from reddit shows you the list of qualifying SOC codes. Note that the instructions for finding your SOC code are missing a step: after step 4, right-click your mouse (anywhere on the background of the webpage) and click “inspect” to see the developer tools shown in the screen shot.

In my case, I have an older / no-longer-available T-Mobile One plan and I was able to add a free line both when they ran the promotion this past summer and again this past week (so I now have two totally free lines on my plan). Since my T-Mobile One plan includes unlimited high-speed data (and unlimited calls/texts) for all of my lines, the free line gets exactly the same thing. It literally costs me nothing more to have an additional line with full unlimited call/text/data.

That alone seems pretty generous since it means you could potentially offer a line to a family member at no cost to you. Even if you don’t think you’ll use the free line any time soon, it doesn’t hurt you to pick it up and you could add the line yourself online or via T-Mobile customer service (note that if you add it yourself online, it shows a monthly cost initially when you add the line, but as long as you’re on a qualifying plan, it will later show up as being free).

I don’t need another line right now, but I may eventually. Someday, my son will need a phone or maybe I’ll have a family member looking to reduce expenses, etc. Will I still be with T-Mobile when that day comes? I have no idea, but if it’s not going to cost me anything to get this line now there’s really no sense in waiting. Or maybe another carrier will offer a good promotion for porting a line to their service and now I’ll have an easy disposable line.

Furthermore, having another line can be useful when there are good T-Mobile Tuesdays deals. T-Mobile Tuesdays deals have gotten kind of weak in my opinion, but every now and then they have something like a $2 or $5 Dunkin Donuts or Starbucks gift card or something. I’ll take another of a great deal the once in a blue moon that it comes around pleaseandthankyou.

But it gets better than that.

Costco Members: An easy $200-$300 win

If you’re a Costco member, picking up this free line could be a three hundred dollar win. If you’re not a Costco member but you live near a Costco, you may want to consider joining just for this free line promotion. Note that this part of the deal can only be done in-store. If you’re not near a Costco / won’t be near one by 12/3, you can skip this section.

That’s because Costco is currently offering a rebate of $200 when you add a line on T-Mobile and bring your own device (the rebate is in the form of a Costco gift card). Credit to Slickdeals as that’s where I originally saw this deal (see the Slickdeals thread here for a lot more discussion of this deal). I went to a Costco store just the other day to do this. Note that this does require that you bring an unlocked phone to the store to activate on the new (free) line you add. I grabbed an old Android phone from a family member that was collecting dust in a drawer and brought it to Costco. I added a line to my plan with a rep at the store and Costco printed rebate instructions for me to complete online (which I did later that night). I followed up with T-Mobile shortly after leaving the store (and several times since) to confirm that the line I added at Costco will be completely free. This is literally a straight $200 win if you value a Costco gift card at face value. Some readers will stop here and quit while they are ahead (though you shouldn’t — see the stacking rebate in the next section).

I will say that this process was pretty darn slow. I waited more than an hour and a half just to talk to someone and then it took about another 45 minutes to actually get the process of adding the line completed. I walked out of the store questioning whether it was worth the time, but that’s surely a YMMV situation that just depends on how busy your store is. I suspect that if you’re in there on a Tuesday morning when they open the juice would likely be worth the squeeze.

But it gets better.

Stacking $100 T-Mobile rebate for porting a line

Stackable with the $200 promo above, T-Mobile is separately offering a $100 rebate when you port a line to T-Mobile (bring a line from another carrier). This looks like it can be stacked. Note that it’s possible that it won’t stack, but I can’t see why not based on the terms and since they are offered by separate entities (the Costco rebate is from their Membership Wireless program and the $100 porting rebate is directly from T-Mobile). Here are the terms for this part of the deal:

Limited time offer; subject to change. Qualifying credit & eligible port-in on qualifying voice line required. Complete port-in within 30 days of activation. If you’ve cancelled lines in past 90 days you may need to reactivate them first. $100 via virtual Prepaid MasterCard® Card. which you can use online or in-store via accepted mobile payment apps; no cash access & expires in 6 months. Card is issued by Sunrise Banks N.A., Member FDIC, pursuant to a license from Mastercard International Incorporated. Mastercard is a registered trademark of Mastercard International Incorporated. Use of this card constitutes acceptance of the terms and conditions stated in the Cardholder Agreement. Lines must be active and in good standing when card is issued. Allow 15-30 days for card. Max 4/account.

Customers who add a new line of service on an eligible rate plan and port their number can get $100 back via rebate on virtual prepaid card.

You go to the following link to start the “rebate process” it can take 6-8 weeks to procesing and you get a “tracking ID” keep that so you can track the status of your rebate.

Don’t have a line to port? eBay to the rescue: you’ll have to do your own research to find a reputable seller, but phone numbers ready to port are readily available for sale on eBay for anywhere from $5-$30. While you can theoretically do this separately after adding the line at Costco, I recommend getting everything set up in advance so you can port a number (transfer a number to T-Mobile) at the time of activating the new line at Costco. The reason for this is to make sure that your Costco rebate goes through smoothly (if you activate a brand new number and then later port in a new number on that line, I could see it interfering with the Costco rebate. You’ll likely save yourself some headache by doing the port at the store even if it does take the rep a little longer). See this thread at Slickdeals for more information and discussion. Note that you do not need to do this via Costco — if you’re not near a Costco, you could just add a free line via the T-Mobile website (after you’ve determined that your plan qualifies) and port in a number to get this $100 rebate. Keep in mind that if you do this yourself, the T-Mobile website will initially show a monthly fee for the additional line, but as long as you’ve verified that your plan is eligible for the free line it will ultimately be free (sounds like a leap of faith, but it works). It’s also worth keeping in mind that if you have four or five real lines to port to T-Mobile (maybe you’ve got Verizon or AT&T and wanted to switch anyway), you could be getting $300 per line for these stacking promos for a nice windfall for switching.

I realized yesterday that I had a paused Google Fi account that I’d been holding onto for my next international trip. Given that an international trip is not happening any time soon for me, I realized that I could have ported that Google Fi line to T-Mobile (I ended up porting that line for a different promotion that I’ll write about as soon as I finish this post). So I missed out on this $100 stacking rebate. At any rate, remember that you too may have a line like that available — and if not, there’s eBay. I believe that some people have successfully ported a Google Voice number to T-Mobile, though YMMV as to whether or not that actually qualifies when they verify the $100 porting rebate.

If you’re able to buy a cheap phone number to port and/or you have a spare number (like my Google Fi example), you’ll walk into Costco and walk out with a free line and $300 in rebates coming in the future. Even if the Costco process takes an hour or two, that may certainly be worth it.

But it gets better.

Stack to possibly get a nearly-free Pixel phone also

This last part of the deal is very much YMMV and this is the part where I will tell you to quit while you’re ahead if you’re looking to keep it simple. Feel free to stop reading here if an easy $300 win is enough for you (and that is totally fair). I’ve done this next part myself, but since the Costco rebate takes 14 weeks to receive and my next T-Mobile bill won’t generate until this opportunity is gone, I can not unequivocally guarantee that it will work. In fact, I can unequivocally say that I don’t know this will work. I decided it was worth a shot. If you’re not the gambling type, take your $300 from above and be happy with it.

However, for the gamblers among us:

T-Mobile is offering some phone promotions that require adding a new line. After you walk out of Costco, you’ll have just added a new line. Before you get too excited, note that my understanding is that any offer that gives you a 100% free phone just for adding a line *will not stack*in conjunction with the free line. That means that any of these promotions can not be stacked with your free line according to the original poster at Slickdeals:

– iPhone “On Us”
– Free smartphone w/AAL
– iPhone BOGO
– $950 off iPhone 12 Pro
– $99 Galaxy S20 FE

The word is that the T-Mobile system will let you get the free/discounted phone, but it will then revert your free line to a paid line. You don’t want that.

However, I’ve seen it reported and I personally checked with 4 different T-Mobile reps (through both Twitter and the chat function of the T-Mobile app) that the Google Pixel 4a 5G deal will stack with the free line offer. Note that some people have reported being told that it wouldn’t stack, but I got the same answer multiple times and had a rep double check a day later to make sure it all looks good still, so I’m as confident as I can be on this. Here’s where it gets a little tough to wrap your mind around…

The Pixel 4a 5G phone costs $499.99 at full retail.

T-Mobile is currently offering 50% off a Google Pixel 4a 5G with either a new T-Mobile line or a qualifying trade-in (which includes some low-value trade-in devices like a Samsung S7 or original Google Pixel). Again, if you do one of those two things (add a line or trade in a device), you’ll get an effective 50% off the phone (this is the key difference with the promos referenced above, where adding a line gives you the phone 100% free).

The Pixel 4a 5G costs $499.99 at full price. You have to finance the phone over 24 months to get this deal (at no interest – it’s just $499.99 split over 24 payments — which should be something like $20.83 per month). The way the deal works is that if you add a line and buy this phone, you’ll get $250 in bill credits split over 24 months (i.e. you’ll get something like $10.41 credit each month as a discount off your monthly payment on the financed phone). Alternatively, if you don’t add a line (which would be silly given the promos above!) you can just trade in a qualifying device and get the same deal ($250 in bill credits over 24 months). Here are the qualifying devices for $250 in credit:

Apple: iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus

Samsung: Galaxy S8 series, Galaxy Note8, Galaxy S7 series

Google: Pixel 3a, Pixel 3a XL, Pixel 3, Pixel 3 XL, Pixel 2, Pixel 2 XL, Pixel, Pixel XL

OnePlus: 7, 7 Pro, 6, 6 T

LG: G8 ThinQ, G7 ThinQ, V50 ThinQ, V40 ThinQ

But it gets better.

T-Mobile is alternatively offering 100% off the price of the Pixel 4a 5G (i.e. giving you the phone for free after bill credits) if you both add a line and trade in one of the devices above. You can essentially get both $250 credits and your monthly payment on the device will be $0. My understanding is that this does stack with the free line because you’re not getting the phone for free based on the additional line alone but rather because of the combination of the line and the trade-in. Again, there’s a chance that something goes wrong here, so be forewarned that I’m going off of what I’ve been told. Some readers at Slickdeals will tell you that I’m wrong and the deals can’t be stacked, but since the original poster seemed to have inside info on the promotion and they specifically said this deal would stack with the free line, I’m taking their word for it as well as that of at least 4 different T-Mobile representatives with which I spoke.

So I had the line that I added at Costco, which would be good for 50% off on the Pixel 4a 5G. I did not have an eligible trade-in device that I wanted to trade, so I bought a used Pixel 2 on Swappa.com for $100 (thanks to a reader who let me know that you get the IMEI number in the order confirmation — you’ll need that number when you place the order for the Pixel 4a 5G with the trade-in).

Traditionally, you’d add the new line, buy the new Pixel 4a 5G phone, and set up your trade-in all in a single transaction whether online or in-store. However, Costco doesn’t carry the Pixel 4a 5G. Furthermore, the Costco $200 rebate requires that you bring your own device to activate, so I needed to bring the old Android phone and activate that when adding the line. I don’t think buying a new phone in the same transaction would have worked for the Costco rebate.

However, a T-Mobile rep was able to help me place an order for a Pixel 4a 5G for free later the same day I added my line based on that new free line I added at Costco and the Pixel 2 trade-in. I confirmed multiple times before and multiple times in the days since that my free line will still be free. I’m essentially getting a $500 phone for the $100 cost of the trade-in device that I’m sending them.

Because the Costco rebate is based on bringing your own device, there is a chance that rebate my rebate will get denied because I’m using that Costco line to also get a subsidized phone. The water here is a little murky: I did indeed activate my own old device when I added the line at Costco and I’ll leave that old Android phone on that newly-added line and actually put this new Pixel 4a 5G on an entirely different account, but it’s possible that when they see that I used the new line to get a phone deal that they will deny the $200 rebate for bringing my own device. I’m accepting that risk.

In the end, if I don’t get the Costco rebate, c’est la vie. I’ll be a little annoyed at myself for having spent the time at Costco for no reason, but with the free added line and trade-in device I am essentially getting a Pixel 4a 5G for $100 (what I paid for the Pixel 2 I’m trading). That will be a decent enough consolation prize. Had I ported a number, I’d be looking forward to a $100 rebate — essentially a totally free phone.

The worst case scenario based on what I’ve done is that I somehow invalidated the “free” Costco line with the Pixel promo. That would mean I’d get charged another ~$30/mo for the extra line that I added at Costco and don’t really need. That would stink, but if that happens I’ll cancel that line and return the phone if possible. There’s some amount of gamble there, but I’m comfortable with it.

If it does stack. I’ll end up with a $200 Costco gift card and a $500 Pixel phone for a net cost of $100 (and the time I wasted at Costco!).

That’s a pretty hot deal. And again, even if you don’t have a Costco nearby, I believe that you could indeed add a line yourself and get the Pixel for half off with that free line or get the Pixel totally for free with a qualifying trade.

Bottom line

Many T-Mobile customers can currently add a totally free line to their plan (while keeping their existing plan with no changes or deletions to their service plan). If your plan qualifies, I think it’s worth adding a line for nothing. If you also live near a Costco, it’s worth joining or if already a member going to Costco to add a line to your T-Mobile account to “bring your own device” (even if you don’t plan to use that line much given that the line is free and Costco will give you a $200 rebate). If you port a line, you can stack another $100. And if you’re a gambler, you may be able to combine all of that with a free Pixel 4a 5G phone. This isn’t the only deal on the Pixel 4a 5G. In fact, it’s one of three I’ve purchased this week alone. I plan to write next about another one of those deals and then later a deal on the Pixel 4a as long as I can continue to crank the posts out because there are some other awesome deals to be had — so if you’re not in a time crunch to get this done today, perhaps wait for the next couple of posts to decide which deal is best for you. That said, I suspect that the deals in this post will work out best for T-Mobile customers. Any way you slice it, you should probably at least consider adding that free line.

“…after step 4, right-click your mouse (anywhere on the background of the webpage) and click “inspect”…”
Inspect what?: “Accessibility Properties” or “Element”?


I added the new line at costco on 12-2-2020 but when I submit the rebate, it gives me back, “The promotion code T01491 is not valid for this date of purchase”.

There was a hiccup at the kiosk but the guys were eventually able to print me out a form with a control number. I can’t figure out how to contact the kiosk at costco by phone either.

I was hoping I could ask for help here: would anyone mind verifying what the promo code is?

my rebate sheet says T01491 but again, the online submission form is returning an error.

I emailed mypromochoice.com and they gave me a generic reply that said they can’t help me.


I checked slickdeals and it looks like the promo has been extended, so if anyone has gotten the deal between 12/1 and now and has a different promo code than T01391, please would you mind sharing? that should be the correct code for me to submit the rebate.

Got a free line added on 11/29 then I contacted T-Mobile expert to help with ordering Pixel 4a (5G). She said it would be free with my Pixel XL trade in and will work with the free line – my bill would stay the same. Today, I noticed an additional line was added to my account that associates with the new Pixel and not the free line. Contacting T-mobile to see if it was a mistake and now waiting to hear back. I will update my result here


after a few hours spending on the phone/waiting for follow up calls. the last Tmobile rep I interacted with told me the Free Google Pixel with “Trade in AND activation of new line” promotion if not stackable with the free line. Also, This free phone promo is now dead on T-mobile’s website – now it is just 50% off with new line and he was able to stack it with my free line. I ended up agreeing with a free line, $10.42/month for the pixel (50% off) and some goodwill $ credited to my account.


Deal is dead. My Costco says promo ended this morning.

What happens if one of the lines on the T-Mobile is moving to a different phone company because their employer decided to pay for their line? Does everything get null and void? The costco card and the free pixel 4a 5g deal.


Great post, and I’m doing almost the exact same stack. I signed up on 11/24 to get the Magenta 2 + 1 free plan, then got my free extra line the next day for a total of 4 lines for the price of 2. I’m porting in 4 numbers (two of them from Numberbarn, $19 each), and got two Pixel 4A5Gs free with trade-in of old Pixel 2’s. Didn’t bother with Costco deal but it was tempting.

To take this one step further, my plan with the 4A5Gs, which I don’t actually need, is to pay them in full, wait the 40 days to unlock them, and then sell them on ebay or Swappa. At that point my $120 magenta plan will be effectively $80 for almost 2 years with all the bill credits, and probably won’t be out of pocket that much after I sell the 4A5Gs in mint condition.


Nick.. one thing though.. Not all the eligible SOCs are captured in the reddit screenshot. Mine was not captured but i could ask T-mobile rep if my account is eligible for free line promo or not.


Super duper fantastic deal..! Based on my last year’s costco experience, I decided to skip costco visit and $200. But, I am going to follow the rest. My wife already has Pixel 2, so basically.. I am trading Pixel 2 for Pixel 4a for free + 1 free line for life + some extra ($100 rebate for port in – $8.19 (Port in cost) – $57.18 (Tax of Pixel 4a)) = $34.63. Thank you for the super deal.. Nick


I gave up on this deal, after spending too much time on multiple phone calls and 2 costco visits. Costco employees dont really want to help you with this and and neither does Tmobile…. and in my area the $200 deal is not advertised so the employees are not familiar with it. All of them might will try to upsell you to a new plan.

You win some, you lose some. If you try this, be prepared for letdown.


I was just at Costco. I was unable to add because I only have one line on my account. According to the rep, it’s minimum two lines and you get a 3rd free.


Also, taxes and fees are about $5/mo on the free line, where I live


When I called them to add a free line, I was told there would be a $20 “assist fee”. I argued (successfully) that there should be no assist fee as it was something I was unable to do on my own. Therefore the fee should be reversed. They did charge $10 plus tax for the SIM, plus $20 for ‘assist fee’, but then immediately posted a $20 credit (while I was on the call) to my account. I actually insisted it show up before we hung up. So keep that in mind.

Also of note – the freeness of the new line begins on month three I was told. The additional line fee IS charged for the first two months. So in my case, it is a total of $20/month for two months then zero cost after that. Like you, I think it’s a good idea to have a line hanging around should it be needed. I used to have one a while back mostly for international visitors when that was a thing.

I must admit – I didn’t think about any free devices though. Good thoughts you have there.


If you have a kickback eligible line (phased out 4/2019) and a dual sim compatible phone. (Pixel 3 forward and ¿iPhones X forward?, OPO 7T with stock firmware and dual sim tray, etc) you can run dual sims and put your data on the new line for an additional -$10 per month on your phone bill. Only downside is it kills RCS on pixels currently, imessage I believe still works normally. Rep said the sim card line gets better coverage than the esim… Dunno if I believe him but that did seem to be the case running dual T mobile sims for me.


I’ve spent the good part of 3 hours on trying to get this to work for me. Costco reps did not know the promotion, and their systems would not allow me to add a line. Had to go home and try to work it out with TMobile (Phillipines unit). Another 90 mins. Now need tow ait 2 days for them to clear things up.

So, it’ll be about $20/hour by the time I’m done. If lucky.


Re “since the original poster seemed to have inside info on the promotion and they specifically said this deal would stack with the free line, I’m taking their word for it.”

In what post # did JMAN100 state that the pixel 4a 5G will stack with the free line promo? TIA,


Whoops, I found where he said “It will stack with other phone promotions not listed in the ineligible list like the free/half off pixel promo.” Not sure how I missed that….


Ok, so I am finally all in on this deal. I just ported a tracfone number (specifially, the AT&T MNVO varient) over the number for the new line that I added at Costco. I went back to the slickdeal thread at (https://slickdeals.net/f/14602288-costco-add-a-line-t-mobile-byod-get-200-costco-shop-card?v=1&p=143770853&comment=success#post143770853), and some are having trouble with the T-mobile $100 possibly for the reason of “Ineligible Activation Source” or possibly “because the line submitted number is not matching the new line.” It may be that the people who added the line and ported the new number at the same time at Costco are having issues or it may be broader than that. So curious minds ask “what did Nick do?”


So I went into tmobile for the last free line promo and previous promos, I was always told I do not qualify bc I am on tmobile one. They basically said I dont qualify for any new promos or discounts ever. I dont understand how your able to get it? I have 2 paid lines and 1 free line. I pay $72/month total for all 3 lines unlimited everything. I could use the extra line but tmobile wont give me anything.


it has something to do with the discounts I currently receive, this is my current plan. I think it has something to do with the Insider Discount that was offered.

2 Lines TMO ONE All In Promo@Work
Applied discounts and promotions:
$10 AutoPay Discount
$20 Insider Discount
$5 AutoPay Discount (Additional Lines)
$40 This One’s on Us (AAL) (Additional Lines)

I’ll recheck it and try again with Tmobile but from my understanding the only way im going to get anything else for free from tmobile is if I leave or switch plans, in which case i would be paying double for what I get now.


I just confirmed with Tmobile, Only thing I can do it switch plans $140 for 3 lines and 4th line free. Basically double of what I pay now. Thanks anyways.

I think the over 55 postpaid plan doesn’t qualify for this deal. It is not one of the codes that is eligible. Too bad. I could do this through Monday since my Costco membership expires the end of this month.

Costco/T-Mobile/Wireless advocates has been a huge Cash cow for me for past four years –

I have the Military One plan – use a line for business, a personal line and a line for “Churning” as well as for family.

I got a Note 9 for essentially $200 another Note9 was for free, S9+ for $200 (x 2) , two S8+ Free plus two Samsung TVs. Plus have churned a few BYOD offers none as rich as the current Costco Cash.

I did go thru Samsung last for my Note10+, net $399 after trading in a Note 9. I use the other Note 9 for managing P2 cards, banks, and brokerage.

I am kicking myself for not jumping on the GoogleFi trade-in. They were offering $325 for trade-in on S8+ I was waiting for BF deal – but trade-in ended 11.22.2020. Was thinking Thanksgiving 2018.

That said if you have T-Mobile and can get the free line(s) do it they are great for churning deals – often deals are tracked or login is based on phone #.

As well as what Nick mentioned about various T-Mobile Tuesday promos – also IIRC the T-Mo 4% on $3K accounts are based on line and not SSN an easy $120 in interest in this desert of interest earning environment.


When I contacted the T-Mo CSR (we have a CSR call center in Salem OR) back when it first was launched

I was told it was per line not per SSN – but was earning slightly less on larger balances.

After the rate cuts earlier this year

I was thinking they were going to follow the rate drop like all the other banks -So I back burnered moving on it.

Till I saw it again in T-Mo Tuesday recently and I see they still haven’t lowered the APR, so seems like a good time to do while we refi, since it’s frowned on new card apps.


T-mobile wants to hard pull me for the pixel deal. I’m willing to trade-in a phone and go with their magneta plan (much harder than my mint plan) but hard pull is a no-no.


Hm that does sound convincing when you put it that way. Am I eligible for the costco rebate as new customer? And going from 15/month (8gb) with mint to 60/month with tmobile is a huge leap, considering I dont use a whole lot of data without traveling.


I know it’s only a few bucks / month, but no mention of applicable taxes/fees for each of these “free” lines at all ? I got one last time and probably will this time, but in my situation, realistically, it’s $5.xx a month. Not a deal breaker, as I probably get more value from the extra line(s) but still a notable difference from “free” imo.


The big question, does this work for sprint customers as well? Or are they a ‘separate’ carrier and have to ‘switch’ to t mobile?


Does this stacking work for new t-mobile customer? I’m currently on mint and looking to switch
