At&t Sim Unlock Debacle

I need some help. At&t won't unlock the Sim claiming "exclusivity" although this device is released by every provider known to man. Anyways, the voodoo sim unlock app for the international S3 is not compatible yet for the At&t 747. What should I do? I need to use straight talk and would like to be able to use t mobiles network. Should I return it or wing it? Anyone been in this position before? Does anyone have any info on whether voodoo app developer can or is working on building an unlock app for US versions?

How long did it take for you to get your code? I just processed an order with them.

done, unlocked. now i need some t mobile hspa radio's to flash.

Hey when I enter the *# code to see if my ATT GS3 is locked I don't get that screen that pops up on the vid showing its locked. How can I tell the phone is locked to ATT?
Thanks

U check by putting a non att sim in. It will ask for unlock code. You dial *#06# to bring up your phones IMEI number not to check if its locked.

Well there was a video on the website that had a *# code to show if your phone was locked, so I tried that and got nothing so maybe I need a dif SIM other than the ATT one

yea i think it only works on international one. doesnt work on mine either

Ummm... Straight Talk uses AT&T's network. You don't need to unlock the phone to use it with them.
Edit: you're using it with ST's T-Mo sim? Why?

root it, then go here. id stay away from direct patching, but it shouldnt harm by plugging it in, reading the nvram.bin and generating a code

I was wondering the same thing. I thought I read you could use either an Att phone or a TMO phone on straight talk with their sims. Also in the TMO GS2 threads there are people saying they didn't even need an unlock code to use the GS2 on straight talk. I've never used Att or TMO but I'm taking a close look at straight talk. In general is it true Att has better coverage than TMO? I know they are both better than Sprint.

Would be great, if the required nv_data.bin file was actually in efs like in the international version, i checked for the file in /efs and it doesnt exit.

Same here.

There's differences in coverage. T mobile more hspa speed 6-7 mb/s, at&t 2-4 mb/s. At&t has more coverage overall coverage tho.

But the AT&T version can't run on T-Mobile's bands. Nobody even knows if it will eventually be able to, either. Until then, you're not even going to get 3G

Well,bought the unlock code from cellunlocker instead,well see how it goes.I want to use the att version on the Rogers network.

Got the unlock code works fine,now using the att cersion on rogers's 4G network !

Thanks for the info on the two networks. I am thinking about waiting for the next GSM unlocked Nexus phone and running that on a prepaid plan that uses TMO or ATT's network. Hopefully we'll see one before the holidays.

[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 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 am curious if the unlock code can only be used on a stock ROM.
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.
Every time I try I get an unsuccessful message..

[Q] Unlock Three UK network note II ?

Evening all,
I'm trying to get my O2 sim to working on my Three network Note 2. I start the phone up and it then asked for a unlock code (sim lock). I've had a good google but sadly everything I've found doesn't work.
I have tried flashing the international stock rom which gets rid of the Three start up screen but when I try the service secret menu I don't get the UTMS option
(tried 4.1.1 and 4.1.2, same results - no menu)
Has anyone got one and managed to get a different sim working in it?
thanks,
Steve

Well I'm still after a proper unlock method, but for now I've used galaxsim unlock from the play store. I'm not one for recommending paid apps but this worked very well. Cost me £2.50 and once I ran it and rebooted the phone I'm pleased to say my O2 sim works great.
I had to root my Note2 mined which took a little reading.. but thanks to some XDA posts got it sorted
I'm still interested if anyone managed to unlock it 'proper'.
thanks
Steve

You could try actually asking Three for an unlock code.

Is there some reason for the OP to think that flashing a ROM will sim unlock a phone?

Got my Note 2 on the Three network on the "one plan" tariff but i got it via affordable mobiles uk on a cheaper tariff and 1400 mins more.
The handset was free and it came sim unlocked with no network branding. Three wanted £36 pm and £69.99 for the handset I got it for £32 pm.
If your in the UK and want a Note 2, try affordable mobiles first.

I used the method linked in the quoted post. I have an UK EE N7105 and I had to flash 4.1.1 to enable the method. It doesn't appear to work on 4.1.2 .
I have tested it with a pay as you go sim from another network. Works fine.

[Q] Unlock code (sent from T-Mobile) does not work

To anyone who doesn't mind helping out,
I purchased a T-Mobile T-889 Samsung Galaxy Note II (4.1.2 Jellybean out of the box) brand new. I've had the phone for 47 days (I bought the phone on 4-9-13). T-Mobile made me wait 40 days (maintaining active account status) before sending me an unlock code. The unlock code they sent me was "07319707"
I did exactly as stated and the message keeps coming up "Network Unlock Unsuccessful". I've called T-Mobile 3 times since I received the code and all they do is escalate the problem to someone else but no one has e-mailed or called me back since. They told me if I try to enter it more than once that it might cause a problem which was after I had tried several times to do it.
I am fully aware of ppl buying unlock codes online and that if you have 4.1.2 that you must go back to 4.1.1 in order for the old code to work but I'm trying to avoid that.
If anyone has any suggestions / advice I would truly be grateful.
I am attaching a screenshot of the email from T-Mobile.
Thank You

I think the best option here is to work with t-mobile support and get it resolved.
I have always found the online chat support much more helpful than their phone support, give it a shot and hopefully this will get resolved.:thumbup:

Phone can be unlocked with an inactive sim. Just make sure you are using non t-mobile sim.
If the phone accepts the unlock code then it's unlocked but it wont show network on an inactive sim.

*status update* I spoke with T-Mobile today. They are emailing me another code...should be in my inbox by tomorrow. They also said that Wi-Fi must be turned off. I don't remember if I did that or not so that might have been an issue.
*GT-N7100*
For anyone reading this that has a GT-N7100 International Note II (my first one) who lives in South Florida (Palm Beach / Broward Counties) I found out today that I threw my money out of the window when I bought the T-Mobile Note II. Either T-Mobile is done or almost finished re-farming the 1900 MHz band down here and I was able to use my T-Mobile sim in the GT-N7100 that I own and able to average about 10mbps download on T-Mobile's network (4 more than AT&T). Around early April I tried using a T-Mobile sim (changed the settings properly) in the n7100 and couldn't even get 1 mbps download. I did not believe T-Mobile would go through with the re-farming in south florida because believe it or not we are not a top 10 market. For those of you who have an unlocked AT&T branded Note II who is still on AT&T... I strongly suggest you either try straight talk or T-Mobile itself and try to use the phone on T-Mobiles network...(Do you really need LTE when it's possible to get 14 to 15 mbps download w/o it?) For what AT&T charges for their service they are straight up ripping people off.

Black listed note 3

So i bought my tmobile note 3 on CL. Bad idea yes i know. Well the phone was working super awesome for 3 weeks and now its reported lost/stolen. So no LTE or service. I tried calling Tmobile and there was nothing they could do. I tried calling the seller and no answer. Ive tried region lock away no help there. Anyone know how to fix this?

RegionLock Away has worked for a lot of people (including myself). Are you sure you can't get it unlocked using that? There's a thread that has a lot of troubleshooting tips somewhere in this section for Chainfire's app (things like using a non-T-mobile SIM, not allowing the app to reboot (i.e. rebooting manually and changing SIM card) and inputting the correct APN settings).
Edit: Here is the thread: http://forum.xda-developers.com/showthread.php?t=2471742
I was able to unlock following the instructions in the first post, so if you haven't done that, you might want to try again.

Well the thing with region lock away is i want to use my phone through tmobile. My note 3 is a tmobile phone

I'm sorry to tell you this, but if it's blocked by T-Mobile, there's really nothing to be done. T-Mobile just won't budge (although I have read posts where people basically lied and got T-Mobile to unblock the device, but I am dubious about those claims). Your only options are to unlock to another carrier, or sell the device. If you sell it on Ebay to an international buyer, that would be the best way to recoup most of your money. Neither option is ideal, of course.

Yep, I almost got burned buying a s3 for my mom. Luckily we met at a tmobile store and verified the esn. Turns out it was reported lost/stolen. Chalk it up as a learning experience.

Like was said a couple of posts prior:
With a BLACKLISTED - N900T - you can:
1) Root, and Use Region Lock Away, it may possibly unlock the sim slot - so you can use an At&t based Sim Card. (Or, you may still need to get an unlock code from someone.)
2) Or - Sell for what its worth on Ebay.- Cut your losses, and find another Handset.
I have bought more than a few from people here locally (different models), seems Craigslist is running rampant (or rather the criminals) with those who are buying a phone, selling for cash on cl, and then reporting lost / stolen for an insurance claim. Then the buyer is stuck holding the bag, and has a tablet. (Or, bends and changes carriers possibly). Its sad but the only true way to be sure the device will be able to be used, is to go with the seller to (Tmo, Vzw, Att etc.) and get the rep to note the account. I have tried to do so via the 800 number, and had mixed results.
Good luck.
Be well.
