[Q]Checking Network lock code doesn't work

Hey guys,
So I got the SGH-I747M from Bell Canada today, its supposed to be the exact same asthe AT&T one hardware wise but some slight software difference I guess.
Anyways, when I try to use *#7465625# to check my network lock status the code doesn't even work to view the Personalization Status, I remember reading on the international forum section a few people had this as well and someone else posted a different code that does the same thing, but I can't seem to find it anywhere when trying to search, does anyone know what the alternate code is to check? or if perhaps the fact that the first code doesn't work means the phone wasn't locked to begin with at all?
Thanks.

Your phone is locked ..... I have unlocked already my t-mobile s3 t999 with z3x

Thanks but that doesn't answer my main question of why the code doesnt work to display the status. anyone else know why or an alternate code?

bump.
Anyone have any idea?
So far my best guess is that my phone wasn't locked to begin with if the code doesn't work, anyone else with Bell or other Telus/Rogers phones able to use the code, does it work, does it not?

Yeah, tried doing the same thing does not work comes up with "Connection Problem or Invalid MMI Code"
I plan to unlock my phone via cellunlocker but I do not have a SIM card to force to the unlock network screen

I've actually been working on getting the lock status code working on my NA variant S3, I've gotten as far as actually being able to load the lock status Page but no information on what is or isn't locked because of how our NA models are not the same as the international model in regaurds to the nv data bin files.
I haven't said anything about it until now as I didn't want to get anyone's hopes up as I don't get much time to work on this. So it could be some time before I have any good results if any. I'm still a newbie as far as being an android dev.

if code does not pull up page you cannot assume phone is unlocked that is poor logic. even unlocked the page should pull up, perhaps with a different code. unlocked phones in the us can still pull up that page.

I would like to know this also. I just sim unlocked mine and would like to know if it worked.And dont have another sim to try?

According cellunlocker.net, the code does not display the lock information on the NA versions of the S3. You have to use a non-"insert carrier name" sim in order to see if the phone is locked and then enter the unlock key. I got mine from cellunlocker.net; cut my used Tesco sim to a micro-sim and boom it worked.

Code doesn't work on At&ts GS3 as well. I unlocked mine yesterday after at&t gave me the unlock code...but only way to check it is by using a different sim.

I got this phone as a gift from my sister using her upgrade. Its maybe 40 something days old....(the phone) ....Ive heard if you're in good standing with At&t (ie: always paid your bill on time...pay over $100 on your monthly bill)...you're treated better maybe? Idk. I just called 611 and asked "may i please have the unlock code for my device"....I answered their security questions and made small talk.. "hows your day going"....mins later......"heres your unlock code"...

My Experience
I used cellunlocker and got an unlock code last week and ordered a T-Mobile sim card ($0.99) which came today. After some careful cutting (I ordered a full size sim card) I inserted the T-Mobile Sim and the S3 booted to an "enter unlock code" menu. I entered it in and was able to immediately access T-Mobile.
I get the same "Connection Problem or Invalid MMI Code" when I try to check but I know it works because I was on the T-Mobile network. Somehow I my text messages and call history for today only were erased so you might want to back up that data before you try it out. Pretty easy process overall.

How many times can you put in wrong unlock code?

Hi Guys,
So I've searched and can't find anything on this. I am going overseas and T-Mobile has given me an unlock code. But every time I put it in I would get "unlock request unsuccessful." I've called them four times and they don't seem to know what they are doing and just tells me they will escalate the ticket. I have tried the code two or three times. I was just wondering how many times can I try it? I've heard that it can permanently lock my phone. Thanks in advance.

First of, are u using a different carrier simcard before inputting the code?

At first I tried dialing #7465625*638*# and then putting in the code but that didn't work. I had a SIM from oversea so I tried that and it didn't ask for an unlock code. It just says invalid SIM. My friend has a Verizon S3 which has a SIM so I tried his SIM and it says invalid SIM also. I don't have any other SIM to try and I'm worried that I'll get oversea and it'll do the same thing with another one of their SIM.

Ok, coz most of the time people doesnt know that you have to use a diff simcard. Have you check to make sure the imei number that tmo had in file matches the one on your phone?

Yea, every time I called them I give them my IMEI and they read it back to me correctly. The email they sent me that has the unlock code has my number and my IMEI and it's all correct. I'm not sure what else to try. I thought about just going through cellunlocker.net but what if they give me the same unlock code as T-Mobile? Does the non-carrier SIM card have to be active and in service? I was thinking that the guy at Verizon told my friend that his SIM was only used for 4g data and the foreign SIM I have wouldn't have any service here. Maybe that's why it's not popping up with the unlock code screen?
I forgot to mention that my phone is rooted. Would that have any affect? Would it be a good idea to flash the phone back to stock and try to unlock?

I thought Verizon and sprint don't have sim cards? The people I know with either carrier, their phones don't have sim cards.

I went to the T-Mobile store and the guy told me he has never done an unlock before and he doesn't know what to do. He told me I should call T-Mobile again. I will be oversea for about two years so I was just hoping to be able to keep this phone since I've only had it for a couple of months. But I guess if it won't unlock then I'll just have to get a new phone. Anyway, thanks for the all the input guys.

Is a direct unlock the same thing as what they are doing with Sprint and Verizon with the nv_data.bin? I was going to do that and then I saw that T-Mobile doesn't have the nv_data file for some reason.

Do you have the i747 or t999? Was the code entered using a custom ROM?

can't make calls or texts

Hello,
just out of the blue my phone can't make any calls or texts. It keeps failing on either of those two, occasionally, I could get one text or call to go through and then it stops working again. I checked and there was full signal at the time, IMEI is still there. I flashed leaked jb roms and cm10 and they both have problems. But the sim when inserted into my unlocked one x works just fine. Does anybody know how I can fix this problem?
Thanks,

Where did you buy your s3?

How they blocked, when I check phones IMEI I can see it, so T-Mobile can actually blocked the phone so people shouldn't use it? is that mean I can use Att Sim card?

Yes t mobile can block the imei if the phone has been stolen or not paid for completely and the person stopped paying installments on it they can block the imei. But no this does not mean you can use it on att unless you unlock it or flash as people call it

So how I know whether tmobile blocked? the phone should anyway read the sim card right? or if they blocked the IMEI number phone can not detect the sim

Where did you buy the phone from? I suggest you get it replaced.

I had a similar problem with my old Galaxy S2 and it turned out to be a bad Sim card slot. You should go to a nearby cell phone store and have them check it. It usually costs around $30 dollars to fix. You can also check if its a bad sim card by inserting it on a different phone and see if it gives you the same error.

Honestly tmobile would of helped more if you bought it from them. While yeah it might be a simple sim lot issue or maybe your putting it the wrong way who knows lol. By guess would be you bought it from a person and they messed it up then try to sale it to you, but really if it was from a store just get it replaced.

OK- I got my Verizon Pixel XL 128 in today at lunch. I set it on the charger, and haven't turned it on yet. I wanted to see what was going on with the Forums before I did. I do have a spare TMobile Sim I can use. I also still have my 3rd version of the Note 7 (That hasn't even gotten the slightest bit hot)... so I am not in a hurry to activate the Pixel XL 128.
If you give me directions, I will perform whatever steps you'd like and report back. If you'd like message me... I can provide my cell and we can talk through it-
Thanx-
Darin

i booted with no sim and it was locked... they assured me they might have a backdoor to make me a developer. i find out first thing tomorrow morning before work. once im (hopefully oem unlocked ill share the dump wealth. put att sim in and only get HSPA not even H+ oh checking bootloader i used SKIPSOFT [TOOL] its helpful no credit to me for that tool.
