If you have nothing keeping you on (like bill credits), port out to Tello, then port back in. I've done this a couple times with good results.

Believe you would need to port out for 90 days and then come back as a new customer.

You can always wait for the Google Fi deal for unlimited at ~$12.50 if you port in four lines. $50 for four lines of unlimited everything, 50GB high speed prioritized, 25GB hotspot is crazy

How did costco/Tmobile do the porting without the new phones? did they port the xfinity numbers to your old phones? My understanding is that the new Tmobile lines do not have to be on the new phones, right?

Thanks for the info, very helpful!
For Step "4. activated all 4 "tmobile" numbers ported from xfinity on my existing phones (same phones that i used for xfinity) (30 min)", was this done at Costco, or can this be self-service in your tmobile online account?

Just tried to buy on TMobile site. It added $79.99 per phone, which is bs even though credit score is 800 and never had T-Mobile.
Out of curiosity what was the total value of the phones you were looking to get (for free). I heard from a TMo CSR that if it's above $3600 ($3800?), they will require a deposit no matter what your credit score is.

Mine showed up the same way on the TMo site. However in looking at the details, you still get the full credit every month.

True, the monthly credit reduces by a few dollars for each line for 24 months if paying down payment of $80 per phone. Instead of $34.50 for 24 months, it's now $31.25 for 24 months. The misleading part is the company shouldn't say "Get 4 on us".

Max 4 discounted devices/account

Nothing in the terms mention down payment if the value of the phones exceed certain amount.

I did the "Get 4 on us" deal myself at the local Costco yesterday. I also was limited to $3000 of credit so I had to put a down payment of $320 for the four phones ($79.99 a phone). I have been assured that I will get the $320 back in credits over the two years. Hopefully that is true.

if they reimburse the downpayment, shouldn't tje monthly credit stay at $34.5? And the line cost should be reduced by $3? If the credit becomes 31.25, you are only getting back $750 over 24 months, and the $80 downpayment would end up as your out of pocket cost

I just did this for a family plan of 4 from VZW to TMO.

2 lines had payment plans remaining with VZ -- TMO will provide a Mastercard pre-paid card to pay off those lines and make the balance $0 so they are able to transfer over to TMO.

2 lines had no payment plans and those 2 lines got a 'free' iphone 17 256 gb over a 2 year contract payment plan

rep told me that for the 2 lines that were paid off via mastercard, they could qualify for any promos that are for existing customers, such as the iphone 17 on us 2 year contract.

also 3rd line is free and 15% employer discount. all 4 lines on the Experience More plan. comes out to $144+tax per month (taxes should range from 18-25 dollars more)

you do have to pay a $10 per phone activation fee, and you do have to pay the TAX on the full amount of the iphone 17 up front, so if its $830 for the iphone x your state sales tax.

Just like any other T-Mobile phone deal, T-Mobile doesn't care if you use the phone or not. You just need to maintain the lines to continue getting the bill credits. So yes, you can sell the phones or simply never use them if you want.

Selling these phones (locked to T-Mobile) that are still being financed by you over the next 2 years is the biggest issue. In the worst case scenario, whoever buys your phones are taking the risk that you close the lines, fail the pay the phone balance due, and the phones get blacklisted. Buyers might not be sophisticated enough to know of this possibility though.
so you can put the number back to your old phone, and never needs to open your new phone if you don't want to use it? Will T-Mobile need your phone when they do the porting?

I had no idea. This what I am seeing.

$34.59 Promotional price $31.25 $-3.34/mo. for 24 months

All four lines showing the same amount. My monthly bill is lowered though.

Due monthly
$86.64 + taxes & fees

When I swap out the 17 for the 16, the down payment goes away even though the 16 is $100 less - $729 vs. $829. As the previous poster said there must be a threshold for the cost of the phones before the down payment kicks in. I don't mind paying the down payment of $100 but it's blatantly shady to charge me $79.99 for each phone.

If you try to sell a phone that is on a payment plan, many sites will block it, such as Swappa.

When you plug in the IMEI number they can see if the phone is paid off, if its not, it will get flagged.

I managed to snag three lines at Costco in the last hour: Essential Beyond plan, $170/month before tax and fees. Two iPhone 17 Pros + one PM, $1000 off each phone, plus a $450 gift card per phone.

Not trying to sell before paying it off. One kid wants to keep using her 13 mini for now, so probably will keep one of the 17s in the box for now. Just want to make sure not using the new phone will not disqualify the credits or unlocking upon paying off.
