Unlocking Samsung Galaxy S2 offficially from ATT - Upgrading, Modifying and Unlocking

Guys,
I just unlocked my Samsung galaxy s2 phone officially from ATT. If your purchased phone has surpassed 90 days, then you can call up ATT and ask for the unlock code. I just did mine last night and tried a tmobile sim and it works fine.
Just provide your IMEI number to ATT representative and you can get it unlocked officially and it will maintain your warranty period.
Thanks,

Hey, yeah most people know about this as it pertains to pretty much any AT&T phone...plus there is a free app in order to do this.

As stated, this is known.

Friend's Galaxy S3 was locked by AT&T

So my friend has a dilemma here. He bought a Galaxy S3 off craigslist a while back. Now one month later his phone was locked by AT&T because it was reported stolen by the person he bought it from. Is there anything he can possibly do? He has already called AT&T and they refuse to unlock the phone, he can't use it whatsoever on his AT&T service.
Unless I'm wrong, he's pretty much screwed.
Whenever a purchase on craigslist is made you must always insist on the person giving a receipt signed by both of you. Your friend seems to be Sol.

Is there more to the story you're not telling? What is there incentive for doing this?

I wasn't aware ATT blocked IMEI like VZW/Sprint block ESNs. That's unfortunate about your friend's phone.
Sell it to someone internationally if you can unlock it.

A family member of mine in the caribbean, Trinidad to be specific purchased a factory unlocked TMO version Samsung Galaxy S3 from someone and now they seem to be having trouble with making and receiving calls on their network (Bmobile is the network there). I told my cousin that he may have purchased a stolen phone and the IMEI may have been blacklisted but I didnt think that was possible internationally? Could there be another reason like the network is not compatible; Bmobile is in the process of setting up HSPA+. The phone is also rooted. Could that be a problem also? Thanks in advance for any help you can give me. Also he has been receiving a software update from TMO, the 94mb one. Could updating the software make it work?

[Q] Are there currently any ways of unlocking a S3 i747m?

Hey guys, first post here. Was just wondering if there are currently any workings ways of unlocking a samsung galaxy s iii i-747m phone.
I have tried searching the forums and also the www but could only find info about the voodoo app which has since been pulled..
Phone : Samsung Galaxy S III 747m
Carrier : Telus
Not rooted yet, but I should be able to do it if needed ( Have rooted my Galaxy Nexus but that is it)
All help is appreciated, Thank you!
No you need to pay for an unlock code

I've used cellunlock.net where some others were not able to find a code.

I've written to AT&T and told them I am going abroad (which was actually true, but who cares) and I need to use my S3 phone with local provider's SIM. They sent me the unlock code for free in a couple of hours. :good:
I paid $7.5 to cellphoneunlock yesterday, the code arrived in about 2 hours and it worked.

Really? I chatted with them online, asked them if there was any way i could have the unlock code for my phone, should the need arise that i have to use it on a different network. Had my code in like 10 minutes.
Thanks for all the replies guys.
I am going to buy a unlock code from mobileincanada as they seem to be priced closely to a couple other sites I've looked at, and I figure why not support a Canadian company.
Thanks for replying so quick guys. I really wish there was a free method of unlocking this phone, but oh well.
I chatted with AT&T and told them I was going abroad. Within 3 minutes they gave me an unlock code for free. I have been an AT&T customer for 2 months only.
AT&T has been known to give out unlock codes for free, but can the same be expected of a Canadian carrier? Highly doubt it.. they will gouge you for $50 for something that probably costs them nothing
I don't think they give out unlock codes at all... I haven't heard anyone or read anything from ANY of the Canadian carriers doing that. I've always read AT&T doing it, if you ask politely.
It can be worth the try, it won't hurt to try. If they don't you can always pay for an unlock code... But always try the free route first.
As asked light night and got denied. I've been with AT&T for years. I might be traveling at the end of the month. I did the online chat and was told I would have to wait until my contract was up before they would do it.

I just registered my bell sgs3 on bell.ca and was able to get an unlock code instantly there.
My sgs3 was purchased outright so that may have been a factor.

Unfortunately that only works on the Stock ROM. Personally I'd rather just pay the ~$10 and get the unlock code rather than going through the hassle of going back to the Stock ROM and running through that method.

I have an unlock code but it won't work when I try with either a Telus sim or a att sim on my Rogers S3.

[Q] *tmobile galaxy s4 says no service after unlocking

I unlocked my tmobile galaxy s4 m919 per your instructions. I wanted to use Walmarts family mobile, which is powered by tmobile, everything was fine until a week ago. They blocked my ime# and I can't use my phone. Were they only able to do that because I was using a network that they power? Or is my phone not unlocked? I wanna exhaust all avenues before buying another phone. A phone call to tmobile will not get this phone unlocked. ..trust me.

You most likely used some un-orthodox un-locking method ...
You will need to contact SAMSUNG and see what they
can do for you. (not tmobile).
Good luck!

Samsung Galaxy S9/S9+ Sim Unlock Code

I want to pre-order samsung galaxy s9 and s9 plus for me and for my son. the both phones will be from t-mobile and I have a question. can I unlock them the same day for at&t ? we have a great at&t plan with cheap family calls so I want to use at&t instead t-mobile. I heard that some newest models are hard locked so want to make sure before ordering. thanks

It depends on the plan you get from T-Mobile. There is are two things you need to do before trying to unlock it. Once you get your phone check the following:
1. Check your T-Mobile folders if there is the Device Unlock App installed (by default it should be installed on your phone).
2. Check your phone's IMEI in the T-Mobile database by using their service here: https://www.t-mobile.com/verifyIMEI.aspx
If your phones have the app and are not blocked it means that they are eligible, so you should be able to unlock them and even use a service like here: https://www.unlockunit.com/unlock-samsung-galaxy-s9-062472
hi, what is the difference between SM-G9650, SM-G965S, SM-G965K, SM-G965L, SM-G9658, SM-G9659, SM-G965U, SM-G965W, SM-G965P, SM-G965T, SM-G965V, SM-G965A, SM-G9600, SM-G960S, SM-G960K, SM-G960L, SM-G9608, SM-G9609, SM-G960U, SM-G960W, SM-G960P, SM-G960T, SM-G960V, SM-G960A, SM-G965F, SM-G960F, SM-G965FD, SM-G960FD, SM-G965N, SM-G960N, SM-G960R, SM-G960R4, SM-G960R6, SM-G960R7, SM-G960T1, SM-G960W8, SM-G965AZ, SM-G965D, SM-G965J, SM-G965L, SM-G965K, SM-G965W8 for sim unlocking ? which one is easier to unlock?
As a policy, the device can be unlocked with the T-Mobile Device Unlock app 40 days after you activate the device for the first time and if the device is paid in full. To activate the device, the SIM card must be inserted into the phone and be active in the device for 72 hours for it to register in T-Mobile's system.
If the device is not paid in full or if you do not want to wait the full 40 days, you can pay for the device to be unlocked remotely through Android SIM Unlock or similar websites. http://www.androidsimunlock.com/phone-unlocking-service/tmobile-device-unlock-app-official-unlock/
Just make sure you're choosing the Device Unlock service since a standard SIM unlock service will not work since you are not able to insert a SIM unlock code into the phone.

Same.
What is the proper procedure to unlock an att s9 to use with another carrier?
The process is basically the same as any other smartphone. Buy an unlock code (this should work for you http://www.androidsimunlock.com/unlock-phone/samsung/galaxy-s9/), insert a SIM card from another service provider, this will prompt the SIM unlock screen, enter the code your purchased and the phone will be unlocked.
wait for few days. some developer will develop customer rome for samsung galaxy s9 then root your mobile and flash it and you mobile will be unlocked. s8 custom rom are available.
SamKey.Info supported directly unlock via usb cable !

So I purchased this phone from T-Mobile, and tried to switch to sprint. I had it unlocked but they still couldn't pry the phone. It seemed to have only unlocked it to AT&T. Has anyone else home through this or know how to fix this issue?
You can get any S9 or S9+ variant unlocked through Ebay including Sprint:

Be very careful that it has a clean IMEI. If it's a stolen phone then you have a nice expensive paperweight.
You really want someone to do a search for you?

If your buy your Samsung galaxy S9 or S9 plus from t-mobile and want to use at&t after unlocking, then you have to use the t-mobile device unlock app to unlock your phone. This is the only option to unlock your t-mobile Samsung S9 or S9+. Only phones purchased from other than t-mobile or metropcs usa can be unlocked using unlock code.
You need open the t-mobile device unlock app and select the permanent unlock option to proceed. you will get unlock successful message and it is unlocked. if you are getting the message "Unlock Failed: This mobile wireless device is not eligible for unlock. For Device Unlock eligibility details, please go online or contact Customer Care." then you have to submit your request for unlocking to any third party unlocking service.
You can can use the below links to submit your request to unlock your Samsung galaxy S9 or S9+ through t-mobile device unlock app

Unlocking a S9

Has anyone gone through a 3rd party service to unlock a s9 yet?
I was told that it's internationally unlocked but not domestically unlocked. The carrier wont unlocked the phone until the phone contract is up.
I'm in the process of having mine unlocked(via code), I'll update if it was successful.
What the Benefits of unlock Samsung Galaxy S9 Smartphone ?
To be able to use it with other carriers.
Trying to unlock my AT&T model, and it's been a week so far. Unlockers on Ebay have been unsuccessful, AT&T has given me the runaround. SUPPOSEDLY it will be done in 48 hours, but I've heard that for the past week.
T-Mobile will unlock their model within a day if you contact them on Twitter. AT&T is just proving why they're an embarrassment of a carrier.
Well, Sprint has the crazy rule of being active for 50 days before unlocking...
I'm debating paying for an unlocked if one can be found.

Mine was an Xfinity Mobile variant, but after trying 3 different companies and trying for a few weeks, I finally got it unlocked. The Unlocking CO was finally able to unlock my phone, it took almost 3 days for them to get the code but it worked.
I actually got a refund from Pro Unlockers, and AT&T finally came through after 2 weeks.

When you unlocked it with AT&T, did you lose Wifi calling ability with AT&T? Curious to know as that will determine if I get mine unlocked for possible future move to another carrier. I understand if its unlocked and I move to a different carrier, that I for sure will lose WiFi calling and other advanced features...I'm just curious if I will lose them right off the bat with the original AT&T carrier.
I have a S9 that I need unlocked. Can u help?
