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?

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!!

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.

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.
A friend has given me a Galaxy Note 2 GT-N7105 to root and change roms, I have put a few custom roms on it and rooted it, but I cannot get it to connect to any network. It didnt connected before I did any of this. I put a new o2 sim in it.
Does anyone have any suggestions on what to do now to get it to connect to o2.
I'm downloading a stock rom from here http://forum.xda-developers.com/showthread.php?t=2032849 uk vodaphone, so im going to try that when it finishes.

I'm not sure what was done to the phone before it was given to me to sort out, but I can only imagine what pain this phone suffered in her hands of installing any rom on it with words galaxy note 2 in the title.

Yes the IMEI number is the same as the one under the battery, my baseband version is N7105XXDMD1, I tried a couple of stock roms using odin, I am now connected to the o2 network, and I have full signal. However I still have the same error when I try and make a call it says mobile network not available. Im at a loss now as to what to try next. I also tried flashing a few UK modems, none of them made any different apart from turning my baseband version to unknown. Any help would be much appreciated. Im thinking maybe instead of flashing to the latest stock rom, maybe I should look for the oldest one and let it do OTA updates. Does anyone have a link to a default or old stock rom for this phone ? Or know how to fix this problem?
I found a post here which looked promising but it does not support this phone

AFAIK, all the N7105's currently in the UK are from either EE or 3, and are almost certainly network locked to them. If the device has been flashed with a generic ROM without being SIM unlocked, that could be the root of the problem.

unfortunately the phone is showing as unsupported i tried looking for other similar apps but couldn't see one for this phone ], I dont suppose you know of any others, or maybe one that will tell me if its locked, or if it is locked what network its locked to, so i can get a sim for that network
I wonder if there is any mileage in doing a manual search for mobile networks to see if any of them show up?

Hi Guys,
I have got SIM unlocked for my Sprint LG G5. Now whenever I try adding a new APN (to use with other network), it doesn't save..
(I have the MSL Code but even in ##3282# and enabled roaming.. No option to edit APN out there..)
Any solution would be highly appreciated..
It should be inside networks settings then APNs ( be sure to put 'default' in APN Type blank, i dont use ##3282# because at least for me it doesn't work for creating APNs

But still it doesn't save.. As a result what's app and other such apps are not working on mobile data for me..

edit apn
Here what I found on another forum
APN edit/save issue finally solved on firmare ZV5.
On the phone enter ##786#, enter SPC/MSL
After the reset, re-unlock and the APN edit/save finally was available under Settings > More > Mobile Networks > APN
The only one problem is how to obtain SPC/MSL code?

How did you unlock your G5 after you did the reset? What firmware are you on?
ZV5 and i had to pay someone
Enviado desde mi LGLS992 mediante Tapatalk
Once your G5 was unlocked, we're you able to change your APN settings? I got mine unlocked but have no data access because I'm unable to change the APN settings.
Yes but i did what this post said, changed my msl to 000000 then did a reset and unlocked again
Enviado desde mi LGLS992 mediante Tapatalk
So you'd have to pay to have it unlocked again after the reset since you'll lose the unlock?

I've tried all suggested methods to add APN on unlocked Sprint LS992 but to no avail (no options to add apn). Able to send texts and make calls but not data. When I enter settings>mobile networks>apn settings, there are no options to add apn. It just shows greyed out otasn. Anyone else come across this and if so, how did you solve the problem?

I'm on the February patch, stock. I'm flashing everything, also, is it normal for your phone number to not be your phone number with a new sim?
My number showing up on about phone is 908-770-6054. This is not my number, could it be human error?

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it
I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23

It holds the imei and other radio proprietary info not sure what partition that data is actually in on this device. I think the efs data is no longer in /efs

Hi,
I cannot access to service mode menu *#2263# , blank screen, I have exynos versio of note 10.
Any idea?
Works fine on my US SD model.
My unlocked 10+ flashed with t-mobile firmware works for that service mode.
BTW did you try other codes like *#0*#, to see if they work? I also remember something about Exynos having different sequence for some codes than SD in the past, but I don't remember details. I think there are some apps that can list all the codes available for your phone, so that would be my next step.

dl phoneinfo.apk or similar that lists all the dialer codes for u to try..
if none work then its possible ur carrier disabled them.. if u have root u can enable them.. on sd devices you would enable in the file /efs/FactoryApp/keystr and /efs/carrier/HiddenMenu..
