S23U for $699

You can choose ATT or Verizon version. VZW one unlocks after 60 days even if you cancel the account. For ATT read below for instant unlock.

1. There are two timelines for the cancellation. If you cancel a line before 3 days it was active then the activation fee is waived. If you cancel it within 14 days from activation under buyers remorse then no bill is charged but activation fees need to be paid. The line activates on right when you place the order not the day you receive the phone on hand so you might have to pay the activation fee of $35.
2. You can use a tello number and port to ATT but you would have to make sure porting is successful by going to https://www.att.com/portstatus/.
3. You can use SIM swap method method to unlock the device.
4. When you receive the phone activate it on ATT with the SIM provided. Make sure it shows up on myATT app/in the web so ATT knows and registers the IMEI in the network. Then put the SIM in another unlocked phone, reboot, make some calls and make sure this unlocked phone is now showing under the line in app/web portal.
5. Now go to ATT unlock portal https://www.att.com/deviceunlock/ and then choose not an ATT customer and use the IMEI of s23 and submit an unlock request.
6.Confirm the unlock request email and receive the unlock code.
7. Only cancel the line after you have unlocked the phone.

Then after unlocking if you are feeling adventurous and want to flash the phone to an unlocked firmware to get rid of ATT bloat you can follow these steps. It's actually very easy to do with Odin.

1. There are many models of s23U but in US two models are imp. S918U is carrier locked version and S918U1 is the unlocked US version. The firmware for these versions are interchangeable so you can flash the ATT model with S918U1 firmware.
2. Download patched odin v3.14.1_3B_PatchedD.zip from https://xdaforums.com/t/patched-o...1.3762572/ as regular odin does not allow flashing mismatched firmware.
3. Download the firmware from S918U1 XAA version from https://samfrew.com/firmware/mode.../Desc/0/10 Extract as there will be multiple files.
4. Connect S23U to the windows PC. Make sure developer mode is turned on in the phone.
5 .Put s23u in download/recovery/odin mode. Power down. Press Volume up and down together and then press Volume up to go into recovery (a green screen would appear).
6. Start odin and then select different files for different categories and then start.
7, It should be now the US unlocked version.

Cancellation of the ATT account and bill thereafter

== Will ATT send me a bill after the account is cancelled?

Firstly, keep the ATT buyers remorse policy handy when you talk to them. See https://www.att.com/wireless/return-policy/ click on "Consumer and Signature Customer Program Devices and Accessories" and here are the policy terms

"Service Cancellations within 14 Days. You may call us at 800-331-0500 to cancel wireless service. You are responsible for all applicable fees, prorated access charges, taxes, surcharges, or other charges through the termination date. AT&T will refund your activation fee, if any, if service is terminated within 3 days of activation. The charges for service used on the account before the service termination date may be applied against any down payment."

ATT will send you a bill with the full amount even after you cancel your account so you have to do couple of things to get rid of charges.

1. When you open the bill in myATT app/att website there will be something called "Don't recognize this fee" under the activation. You can click on it to get rid of a activation fee. This is an instant and automatic credit. Also this works even if you cancelled the account after 3 days.

2. Chat with CS to get rid of rest of the charges. Make sure to not fall for credit in the next bill/adjusted in the next bill, Be polite but persistent that you want charges to be credited now. Bring up the polict if you have to.

See https://slickdeals.net/f/17327499-oneplus-nord-n30-5g-128gb-unlocked-chromatic-gray-cph2513-best-buy-0 recent interactions with ATT CS.

Your comment cannot be blank.

Featured Comments

if they don't already have an att or verizon account, getting one takes a hard pull (credit check) which has a moderate impact on credit (which is very important in the US). It's a nuissance.
It may also take time to figure out why the order doesn't go through and/or it gets canceled, etc. In other words, don't make a friend or relative do it for you.
$300 savings over the S24 ultra. Not much of a deal.

Why does Samsung do a software update every 23 minutes and leaves other stuff wide open forever?

I just found it weird. :/

You can get a tello number with eSIM phone outside US I think. You can also get a google voice number too.

Both of them. ATT unlock can be done quickly as I mentioned in the post. For VZW, you have to wait 60 days

Thank you OP, the ATT sim swap unlock worked. I used a Google voice port (just pay $3 easy). Smilie

Note to others for sim swap step 4, where you need to wait for your second unlocked phone to appear in the ATT web portal, this can take over an hour. I almost lost hope, but an hour later it showed up.

I thought it was a soft pull on credit? Maybe hard pull if you sign up for a 0 down phone on a plan?

Depends on how you look at it. There are a group of people who believe S23U is better than S24U
Why so. Any reason?

10x telephoto camera to 5x telephoto camera downgrade. Not curved screen, shift while switching camera lenses, muted screen colors etc. But of course there are a lot of upsides too like 7 yrs of upgrade, an absolutely great screen with strongest gorilla glass (dropped face down twice, not even a scratch) etc.

PSA: As I l was ooking at BB website they dropped the price for ATT S24 to $549 which can be unlocked using the same method I described here. I posted a thread about it.

https://slickdeals.net/f/17333487-samsung-galaxy-s24-128gb-onyx-black-at-t-549

I don't think base S24 warrants a $150 premium over S23 but you do get 7 years of OS update with S24.

It's better he /she look online Craigslist or offerup would find a better deal without agreeing for 2 year contract maybe you would pay a bit more but your friend wouldn't be stuck or whatever, I usually get mine that way I live in the US
