Bought it off of craigslist. Whenever I put my sim in it says it needs a code to unlock the sim or can only be used with a specific sim card...
Tried going to the store and calling att and samsung.. no luck. Anyone able to help with this?
I'm going to ask it. Are you sure it's an i637 and are you on AT&T? If so, keep calling until you get the right tech at AT&T. You probably just need the P-U-K code.
I called them up and all they gave me was an unlock code <_<
Hello, I have AT&T and my friend has T-Mobile. He upgrades so often that I buy his 'old' phones and he calls T-Mobile and gets the unlock code for me, then I give these phones to my wife so she can use it on AT&T and have WiFi, but not have to have a data plan. Works great. Plus, I can play around with Android, which I like.
Question - I just purchased his 'old' (from June/2010) Samsung Galaxy S Vibrant. He called T-Mobile and after about a day, they sent the unlock code. I went through the necessary steps (verified IMEI #, powered down phone, put AT&T sim in, power phone on, received code screen). I put the code in, and it said that it was an invalid code.
So we called Tmo customer service again, and verified the code and everything, then tried it again. Said the same thing.
I don't want to try it again as I am afraid it will brick the phone. Am I missing something? Do you have to put a # or * or - or something else in with the code?
Thank you in advance.
Edit: I should mention that I also downloaded the Samsung Galaxy S xda developers unlock tool for Mac to find the code in the phone. I tried the non-root version, and it did not find a code. I would have tried the root version, but I have no idea what that means.

I have exactly the same problem on my T959, hack software could not find the unlock code on the phone. Paid unlock service for Provider and manufacturer code still did not work.
Have you found a solution? Are you using the stock ROM or was it ever changed?
Same problem... I cannot get a code...
I am told that the device is not found, even though it shows that the Samsung Galaxy S Fascinate is connected. Also during the generate the unlock code, the program could not find the nv_data.bin.
Could you tell me what I am doing wrong, and why it does not look for this file on my phone?
go to some forum to seek way out .
way out, waiting too
Same here I ccan't get my phone to unlock with Tmobile provided code.
Anyone solve the problem? Mine don't work too.
it would be wonderful to figure this out
fix
did your friend ever change the rom on the device? I had the same problem on my captivate. The unlock codes for all of the galaxy s series are built into the phone and simply hidden. If the firmware has been changed (ie, upgraded to 2.2 or flashed another rom) then the codes are altered.
sucks. but now you have to go to youtube and search "unlock ____" and it is no trouble on a pc.
Hey guys, I'm new to the G1. I just picked a used one up the other day to use over seas. I reset the phone not knowing I need a SIM in there to actually use it. I don't have access to a SIM card currently, but I will have one when I go over seas. Will the phone unlock so I can root it with a SIM card from a different carrier? Or do I need to have a TMobile one in there? My plan leaves tomorrow early morning, so I'm kind of in a bind when it comes to solving my phone issues.

Oops, I thought I posted in General.
The sim card from n e where will work for the rooting process so don't stress that. These instructions will get u n to the phone with out the sim card. http://theunlockr.com/2010/01/10/how-to-activate-the-g1-without-a-data-plan-or-sim-card/
Good luck!

If the phone is locked , you need to get it unlocked first....otherwise it wont use any other network sim other than t-mobile.
The easiest way to unlock it is to call t-mobile and ask them for unlock code by giving them IMEI number of the phone (can be found in the MENU--->SETTINGS---->ABOUT PHONE----->IMEI NUMBER)
They provide the unlock code for free.
Once you have it unlocked, then whatever sim you insert, you will be asked to enter the unlock code. Enter that code and phone will start using that sim.
If you dont get it unlocked here from T-mobile then get it unlocked from the country where you are going...but the charges and success rate of unlocking depends on which country you are going to.....it is very easy and cheap in South Asia like India and Pakistan.....but difficult in Middle East.....
So the best alternative might be to buy a cheap GSM phone there and sell it when you return here.
Have a happy and safe journey
Thanks for the help everyone. Unfortunately, Tmobile couldn't give me an unlock code since I'm not their customer. I've got some more digging to do. I came across some sites offering the code for a fee, are they legit? I just don't understand how they get the code when I can't.
Go to ebay and buy it. for abt $6.49, they will give the code to you. I unlocked mine via ebay... Try any seller.
Based on timezone, buy from US seller or your local seller to get it quick.
Like for US try http://cgi.ebay.com/UNLOCK-CODE-T-M...025?pt=LH_DefaultDomain_0&hash=item1e5f205f99
Make sure u provide them your IMEI code.. dial *#06# Or look under battery.
Hello All,
Recently got an ATT branded 8X and so far, with a few minor issues, I love it. That said, I have a bit of a problem with unlocking. I purchased an unlock code from *htcsimunlock.com and then inserted my TMO UK sim. Phone booted up and then it asked me for the unlcock code. I enter it and it comes back as a sim error. I tried this with a TMO US sim too and had the same result. The company will not return my emails either so I am not getting much luck on that end either (buyer beware).
So, I thought I would come to the one place I always seem to get answers, whether I like them or not :crying:
Ideas please? Cheers.

Unfortunately, they sent you the wrong unlock code. The code is associated with the IMEI of the phone, not the SIM card.
Keep trying to contact them.

Thanks drtolson. I realize that the the IMEI is the basis for the CU. My problem is after it asks me for the unlock, I get an invalid sim error message. I think you may have misundertood my question.
I have tried repeatedly to contact them but they just ignore me. Not cool I know but thats the fact of it.
The only thing thats related here is the fact that both sim's have been TMO. I can't imagine it being an issue and it has not been with all the phones I've unlcoked before... I'm stumped.
The reason that you are getting the invalid sim error message is because the unlock is not working, then it detects that the sim is not an AT&T sim and says that it is invalid. You need to get the right unlock code. And get a refund for the wrong one that they provided you.
Never use any imei unlocking services!
99% of operators lock the phones by themselves due to a huge leakage at the manufacturer's side.
So i, as an unlocking expert for last 20 years, advise you all guys NOT to use any IMEI based services.
Most of the unlocking websites are offering a wide range of unlocking services based on your IMEI number, but for last 3 years, the amount of successful unlocks via IMEI is greatly dropped down to 1%. So if you got your phone unlocked by IMEI today it does not mean that the next phone will also be unlocked.
Moreover - nobody will return you the money before they earn enough, most of them are buying the codes same way you do but in bulk and before they get enough to cover what they have spent to get it - no returns Sometimes no returns at all.
It's a huge cheating and a gamble. The feedbacks they leave on their websites are written by themselves. And there are lot of tricks you guys don't know.
So just DON"T USE IT!
Use online unlocking solutions where you can see what is happening and for sure there is a person behind the unlocking software, so at least you have a chance to return your money.
Spread it.
Regards
Certainly seems like I'm the victim of a scam here. Now I have to decide if the $15+/- I've paid is woth all the aggrevation and time of a charge back. I hate being rooted if you know what I mean...
I've tried to contact these guys three more times since this post all to no avail. Please guys, keep this in mind if you're looking for an unlock. Don't use w.htcsimunlock.com/.
Perhaps we should have a sticky of unlock guys we know to be legit. What about you maxrfon? You have any way to unlock an 8X?

The chance to get the right code is based on the professionality of the service you use... a good service offers you fully refund if you send in Video with the missing functionality of the code.
There are a lot of cheaters on the customer-side too...
Also got scamed by *htcsimunlock.com , but i have called my bank, their money gateway and posted a complain. I hope they dont get the money, because its only reserved. Shame..

You know, now I'm not so sure... I also had a Lumia 900 and the battery went. ATT replaced it with a refurb and since my original phone was already unlocked by them they gave me the unlock code for that one too. I could never get it to work so I got on the phone with customer service. They took me through the steps and they could not get it either. They sent me another one again, warranty replacement and gave me an unlock code for that too. That didnt work.
Today I read this post on the Lumia forum; http://forum.xda-developers.com/showthread.php?t=2056808 I tried it and it worked. It unlocked my Lumia. I think I'll try the 8X tonight and see. If it does get unlocked, I'll let you know.
I have nothing to lose by doing this now.

Should I say that I have bought another code at different site, and still no go! I think that some providers changed unlocking codes for our devices.
Hello XDA-Developers,
I am at my wits end. I can not for the life of me find a Sim Unlock code for my Samsung Note 3 N900W8.
I will start from the beginning... I purchased this phone from a woman who is the manager of a telecommunications in London ON. She listed the phone on Kijiji as "Brand new in box, unlocked!". I met her at a kiosk for my carrier to test the phone on one of their sim cards. It turned out the phone was sim locked. She seemed nice enough and genuinely surprised when it came up sim locked. She said she had received the phone as a promotional gift from her company, but didn't like the size of it and wanted to use her existing phone. She asked me if I would prefer to have her get it unlocked or she would take 50$ off of our originally agreed price to put towards the unlocking cost. I opted to get it unlocked myself, my mistake lol.
First I had to find out which carrier it was locked to so through a process of elimination I figured out it was locked to Bell. I contacted Bell and asked to get a sim unlock code from them. They said that they have no record of my phone in any of their data bases and that I should contact Samsung and confirm that my phone is locked to Bell. I contacted Samsung who confirmed that my phone is locked to Bell. I contacted Bell again and they put me through to tech support. He was a nice guy, but didn't give me the answer I wanted lol. He said that because my IMEI is not in any of their data bases that there's no way for him to give me a code. He suggested flashing a different kernel and it would remove the sim lock? I'm sorry I am not that knowledgeable when it comes to this stuff. Anyways, I have taken the phone to 3 reputable phone repare shops in my area and tried cellun******.net. All have said that they can't find an unlock code?
You guys are my last resort, any and all help is greatly appreciated.
Thank You!
