Hello
I really need some help
I bought a Samsung galaxy nexus week ago and its worked until today
When I turn the phone on it asks me for "sim network unlock pin"
how should i get the unlock pin
could flashing to a new rom have un-done the unlock? ( i flashed but it still has problem )
I'm having this EXACT same problem.
VERY frustrating!
to sim unlock http://forum.xda-developers.com/showthread.php?t=1548210
i have the AT&T Samsung Galaxy S3 SGH-I747. the phone is already unlocked so i know it should accept foreign sims but it doesn't recognize any sim i put in it. so far ive used 3 different simple mobile sims and none of them have worked. i called AT&T to find out if my IEMI was blocked or blacklisted but they said no, the phone should be working perfectly. plus weird thing is, i get the signal bars next to the battery as if the sim is working but it still says "No Sim. Insert Sim Card"
the phone is rooted so i was wondering maybe that has something to do with it? the phone was working perfectly fine until i rooted it. the specs are:
Android Version: 4.1.1
Baseband Version: I747UCLEM
Kernel Version: 3.0.31 - 274808
Build number: JRO03L.I747UCDLK3
please i am very desperate to get it working by tonight. does anybody know why my galaxy s3 won't recognize any simple mobile sim put in it? is there software im missing or updates i need? i already tried unrooting my phone, no luck.

Who is your network provider? ATT or simple mobile?
Do you still have an imei on your phone under settings?

I hate to ask the question but are you sure you had the phone unlocked and if so how did you do it?

yes the phone is unlocked. maybe i forgot to mention this earlier but it was using a simple mobile sim card perfect before i rooted it. i called AT&T international and they gave me the unlock code after i asked. i didn't need it tho because they told me if it wasn't unlocked, after i put the foreign sim in, it would prompt for the unlock code but the phone never prompts for one, just says "No Sim insert Sim card", something along those lines. further more i was informed that if it wasn't unlocked, it would say "unrecognizable sim" instead of "no sim". the fact that it says "no sim" means it won't read the sim card. the thing is no matter what sim card i put it (i tried 3 or 4 different ones) the phone still says "no sim"
i tried changing the modem to every single one compatible with the SGH i747 model and nothing helped. i tried changing the modem to a Tmobile modem because i know simple mobile uses Tmobile radio towers but that didn't help at all. i deleted all the cache and unrooted the phone but that didn't help so i rerooted it again. i don't know im just extremely frustrated right now. i've spent hours on the interenet and called AT&T international countless times to try and fix it but they always tell me its the sim cards fault but i know its not because i've tried it in other phones and they work. i'm just looking for a miracle here.
oh i did try to flash a custom rom and kernel but it didn't work and i received an error message and rebooted it without tampering with the rom and kernel again. maybe that has something to do with it?
Try doing a kies factory restore mate.

I have the same situation, after doing this:
Just dial the following keys *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....
Now it does not ask for the code unlock when i insert the t-mobile sim card, it shows error mm#6 or its says, sim card not allowed cannot conect to the network.
Hey OP, how did you solve this issue?
Rooted Galaxy S3 No Sim
Hi, I have exact same situation. I have an unlocked S3 originally locked to Telus. I got it rooted and lost the unlock -- it only reads Telus/Koodo sim card. Anybody help please?
PS: S3 shows the signal, however does not recognize the SIM!

Tried this approach and never worked (since it was unlocked using network unlock code already).
thanks anyway
You unlocked using a code, but you lost the unlock when you rooted the phone?
please help!!

You have to be on completely stock 4.1.1 for this to work...
Same Problem
Sadly to say I have the same problem but on a new Samsung Galaxy Note 3 N900V. I bought it online and it was supposed to be factory unlocked but it doesn't work on Fido, koodo, or bell; so I am not sure if it is factory unlocked. It says No SIM on all three sim cards. I tried rooting and it is still the same. I don't know what's wrong but I tried contacting Verizon who is the carrier of the phone but you can't get help unless you have a phone plan with them. And then I want to be using this on koodo and they won't help you because the phone is not from them. I am going crazy, anyone know how this can be fixed.
I do not have "[4] NW Lock NV Data INITIALLIZ"

What ROM was on your phone? Is it the i747 or i747m? The thread you linked is for the international version of the Note 2.
Hello there.
I have a note 2 (GT-N7100).I bought it from uk but i live in Bangladesh.When i insert my local sim, it says "sim network unlock pin".I tried chainfire region lock away app but the problem still remains.So if anyone knows how to solve this problem then please suggest.
Now if i flash my device with a custom ROM (Omni, CyanogenMod ,D4 Nitro etc) is it gonna help to remove the region lock( Sim Network unlock pin"? Please suggest.
Thanks a lot
So im going to sim unlock my phone and i already have my new sim ready. I still havent bought my sim unlock code. The wierd thing is that i have had tried putting the new sim card and i dont get a prompt to type in my sim code. It just takes me to the lock screen and when i unlock the lock screen it takes to the home screen. It does tell me in the drop down status bar that the network is locked. So im not sure why i dont get a prompt. Is it becuase im using a custom rom? Do i need to go back to stock?
Bought a D851 and when I go to SIM unlock process and I tap Service Provider Lock I get a message "Your phone is not personalized." Will a custom ROM carrier unlock a phone? I can enter a SIM network unlock PIN however.
No. You would still have to get it unlocked by T-Mobile.
OK. Thank you.
