Added notes thanks to resseeker
  • If you get error during sign up, its most likely an authentication error (TMO can't verify your credentials i.e. social w/ ID) you can try doing this in person at a BB store
  • When you sign up online, as you are about to check out, you'll have to agree with the tmobile terms and conditions.. THIS IS WHERE YOUR PHONE NUMBER IS LISTED. WRITE IT DOWN OR SCREENSHOT.
  • Call 1 800 T MOBILE, tell CS agent that you wish to cancel the line. You don't need to stay on hold for 2 hours. Just have them call you back when you are first in line.
  • If they mention "are you returning a device to the store?" say NO. There is no device associated with your new line/account.
  • They'll cancel your account effective immediately.

Steps for ordering online:
1. Follow the link to add "Samsung - Galaxy S21 5G 128GB (Unlocked) - Phantom Gray" to your cart. Make sure you have select "$499.99 (Activate Today) Unlocked." It should say $499, but just wait a minute. Click "Add to Cart."
2. On the next screen, select T-Mobile (Starting at $399) and click "Continue."
3. I chose "Create a New Account."
4. Select "I want a new phone number" and enter billing ZIP.
5. Select a phone number area code and proceed.
6. I declined to trade in a phone, but you can give that a shot. I selected "Continue without trade-in."
7. Select a plan for your zip code. I was able to select the Essentials Unlimited 55+ for $45/month, even though I'm not that old.
8. Skip the Geek plan and go to cart.
9. You should see an Order Summary now. The phone should ring up as $399.99 + tax.
9. Choose pick-up or free shipping. I chose free shipping and it did arrive the next day with an unopened box and a T-Mobile SIM in the package.
10. Click Checkout.
11. Sign in to Best Buy for checkout.
12. Continue to Mobile Setup -- NOW YOU HAVE TO DO THE T-MOBILE CHECKOUT.

For a new account, this will result in a credit pull.

13. On the first checkout screen -- a Best Buy screen with the T-Mobile logo, too -- enter the information requested
14. BEFORE YOU CLICK CONTINUE, CREATE AN ACCOUNT PIN AND WRITE IT DOWN. THIS WILL HELP YOU WITH CANCELLATION.
15. Click continue.
16. In a screen or two, you should receive a T-Mobile invoice that includes (1) your account number and (2) your new phone number. TAKE A SCREENSHOT AND/OR WRITE THIS INFORMATION DOWN. IT WILL HELP YOU WITH CANCELLATION.
17. Finish checkout and wait for your phone to arrive. I recommend waiting for your phone to arrive to cancel, in case you have issues and need to return the unopened phone.
18. CANCELLING YOUR NEW PHONE LINE -- updated original post comments:

- Call 1-800-T-MOBILE.
- Enter your new phone number when prompted.
- Enter your PIN when prompted.
- Say "Cancel line" and confirm what the automated agent says.
- When you are told you have a two-hour wait, choose the option to have them call you back when you are first in line.
- If they asked whether you are returning a device to the store, SAY NO. There is no device associated with your new line/account.
- After I received the call back, the CSR made me wait an excessively long time for the cancellation to complete, and asked me questions about repurposing my line every once in a while. Probably a tactic; possibly a dumb process.
- You should have $0 balance due, since you paid outright for your phone and you never activated your line.

Your comment cannot be blank.

Featured Comments

Someone did post in the Samsung flip thread that they did this for Samsung flip and didn't have to pay anything to T mobile at all since the phone was already unlocked and purchased outright.

The response from the other thread is pasted below

I paid $0 to cancel a never-activated line. When you pick up the phone from bestbuy do not put that sim inside. Put any other sim in. When you call T-Mobile, if you never jotted down the never activated Ph #, you can use the SIM card it came with to look up the never activated account to be able to cancel . It's $0 cause the line was never activated and because you bought unlocked outright
For everyone looking for how to finesess this deal:

1. Follow steps as mentioned in Wiki (if you get that error, its most likely a authentication error where TMO can't verify your credentials i.e. social w/ ID) you can try doing this in person at a BB store. I was getting this error despite checking everything 15x, finally tried doing it on the mobile BB site and it worked.
2. Do not insert your SIM into the phone. When you sign up online, as you are about to check out, you'll have to agree with the tmobile terms and conditions.. THIS IS WHERE YOUR PHONE NUMBER IS LISTED. WRITE IT DOWN OR SCREENSHOT.
3. Call 1 800 T MOBILE, tell CS agent that you wish to cancel the line (you can make up whatever excuse you want)
4. If they mention "are you returning a device to the store?" say NO. There is no device associated with your new line/account.
5. They'll cancel your account effective immediately.
6. The phone is FACTORY UNLOCKED, can be used with any compatible provider.

I was able to do this process for 2 phones. $400+tax for a FACTORY UNLOCKED S21 5G is a great deal imo.
why did this get downvoted to oblivion. isn't it a super good deal? you're not locked into tmobile.. just cancel the first day and you essentially get an S21 for $400? cheapest mint condition on swappa is like $680

No clue why no one found it exciting. I did it earlier today and felt it to be a great price for an unlocked current flagship phone.

shows 500 for me, but the TD is because it was listed as "Samsung - Galaxy S21 5G 128GB 399" not with activation by tmobile when first posted.

I'm getting "We're sorry, there was an issue processing your request. Please try again later." when trying to add a line to my existing account.

Anyone know how to fix this?

Is it really that simple to cancel? No catch? Sounds too good to be true.

Are there really no strings attached or repercussions for canceling right away?
