[Q] My galaxy s3 won't recognize any sim?

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!!

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.

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.

No Service - HELP!

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?

ATT Phone not Acknowleding SIM Card

I have an ATT phone and tried putting a TMO SIM inside. Running Stock 4.3.
1) I am not getting a 'network sim lock' message prompting me to enter a code. I never had it at 4.1.1 to do the unlock code sequence; just 4.0.4 (when I did get the unlock sequence) and now 4.3.
2) Even though the Tmo cell is in, it tells me the phone is not registered on any network.
3) GO to settings > more > Mobile networks and get the 'Insert Sim Card to Access Network Services' even though there IS a sim in there.
Any halp?

I had the same problem when I updated to 4.3, I flashed a modem from here http://forum.xda-developers.com/showpost.php?p=47817339&postcount=23 through CWM and after I rebooted I had data working and the SIM was being read.

How to enable video calling on unlocked SM-N910A On T-Mobile network

I am using unlocked SM-N910A On T-Mobile network. I am trying to enable video calling on Phone app. I checked setting under Phone app but did not find anything.
I also noticed that when I go to Settings -> More Settings - I see first 'Network or Sim card error' popup with ok button and after that other options (i.e caller id, call forwarding,auto redial etc) are loaded on screen.
Any input will be great if this can be done or limitation.
APN is fast.t-mobile.com
Settings -> Connections- > Mobile networks - > Mobile Data -> "Enhanced 4G LTE services" is checked.

I'm on ATT using the same phone, and I don't think ATT supports video calling on their phones. I don't know for certain, but my last 4 phones were all ATT and none of them had native video calling. I always had to use apps like Tango. I could just be in the same boat as you and just don't know how to activate the feature or something.

Thank you for reply.
I also noticed there is no wifi calling option. there is also "sim card or Network error" while setting forward calling.
Based on following links,it seems it is a limitation

5.1.1 is the latest version, but the only way to OTA is to use an ATT sim card. You can Odin the files though.
I recommend updating just because 5.1.1 is much stabler, but I don't think it'll help you. I'm on 5.1.1 and as I said, I can't find any way to use video calling.

I can't answer any of the last 3 questions, but can the first few.
OTA (Over The Air update) is not possible without having an ATT sim and being connected to the ATT network.
With a different sim, the phone will ALWAYS say that no update is available and that your phone is up to date when it isn't.
Kies will act similar as to not having an ATT sim. ATT doesn't upload their updates to Kies.
The only way for you to update would be:
1) borrow someone's ATT sim card and use it to connect to the ATT network
2) go to a Best Buy with a Samsung Experience area and ask them to update your phone. They'll do it for FREE and it doesn't matter where you got your phone. You do need to tell them that you're using the ATT phone on a different network. This will male sure they flash the correct firmware and not brick your phone.
3) Use the latest Odin file to update your phone yourself. This is basically what they'll do at Best Buy, except that you'll be solely responsible for the outcomes of your phone. The Odin files are posted in the ATT Note 4 General thread. Just do a search for Odin.
