[Q] "no sim" error on my other carrier, currently overseas can't make calls.
Hello everyone,
Long time reader first time poster because I have searched for the past 2 days to solve my problem but it is kind of an emergency at this point.
I am currently overseas, last year I was here I was running stock GB and unlocked the simlock by contacting AT&T and getting a code. This year I am upgraded to stock JB but I get a no sim error with my overseas carrier and the phone doesn't ask for code at all. I tried putting in the ATT sim again and that works but can't use it here because its too expensive. I have tried other people's sim cards (total of 3) all of them get no sim error. This tells me the sim lock is still on there but I can't do much since it doesn't ask me for code.
I have also flashed siyah kernel and paranoid rom since coming overseas still no luck. This was mainly because stock JB was horrible.
I tried galaxy s unlock app but won't see my internet connection, I am not sure if it would be able to solve my problem anyway. I can't try the paid version of sim unlock because I can't get it charged to my ATT bill. I heard there is a free version but couldn't find it after searching for hours, seems as the developer wants this to be paid anyway.
I tried choosing multiple carriers under network settings but no luck.
I am sorry if I missed something obvious. Seems like Kies\ATT messed up something while upgrading me to JB
I have contacted ATT to ask if their JB upgrade locking sim is a known problem but all I got was a "are you sure you did it right". I have an unlock code from ATT though, just can't use it because the phone doesn't ask for the code, just says "no sim, emergency calls only"
I have flashed different modems just to see if that would help, nope
I have searched and read every similar thread, I would search more but I really need to solve this quick. Sorry if I missed any details first time posting.
Thanks in advance.
Don't know if this will help since I haven't tried it, but I found this. Maybe this will allow you to enter the unlock code?:
If your Samsung is not asking for an unlock code and it only reads “Network Locked. Emergency calls only” or “Insert correct SIM card” you can use one of these two formulas:
#0111*UNLOCKCODE#
#7465625*638*UNLOCKCODE#
hmm both of them gave me mobile network available error, weird I would guess it wouldn't check for that.
,just to make sure , I just enter these on the keypad and press call right ?
With that type of code, you don't have to press call. If it is supposed to call up a menu or dialog, it will do so when the last digit is entered. If the phone does nothing when the last digit of the code is entered, then it is probably a code that is not recognized by the phone. So I guess those codes don't work for the SGH-I777. I don't know if this is dependent on firmware. I do know that unlock doesn't work the same on Jelly Bean. I've read the unlock methods don't work. See here. I guess you could flash ICS stock plus root and then use one of these.
or... can you call or chat with an AT&T tech support to ask how to apply the code in your situation?
I found a list of a lot of codes, tried some of the ones related to network lock, one of them asked for password, i entered it and it said unlock successful yet still not working. I just rooted to stock gingerbread still no sim error yet ATT worked and sent me a text for international rates.
I just don't know what happened whist upgrading to JB.
I have a similar problem where my unlock code that used to work no longer works. Just out of curiosity, does the Serial # shown by GalaxSimUnlock app match the one listed physically under your battery? I'm not aware of how to check for the serial number other than that app. On mine, I noticed it got zero'ed out, and if my hunch is correct, I think the unlock code recognized by the phone is based on that serial number (among other things), so the one supplied by AT&T won't work anymore. I'll have to get a new number based on that zeroed out serial number or change my serial number somehow.
Sorry I flashed another rom already but I will try to reinstall everything and check later today. Idk if the app works with gingerbread, it should.
Yes, it works with Gingerbread as I was able to use it. I was hoping that if I restored to Gingerbread, my serial number would come back. But no dice. I'm really curious to see what your serial number is.
just tried to check but the app keeps crashing on mine. I tried with anothe unlock app i got undefined under serial.
i tried everything and nothing.
im in vaction in other country, i put a sim data on my phone and i lost the IMEI code.
i dont have calls out and in, no whatsapp.
im totally disconnected.
i tried galaxy codes like *#32489# but nothing.
can anyone help in that case, im pretty helpless here.
thanks

Its only show me the imei number and i have null.
I need the service menu code to change settings.
Well, I searched for this issue with LG G2 and did not find anything that could help me.
To make it fast, when changing the sim to another from another carrier, the window asking for a code won't pop up....
There's another way in wich you introduce a number on the dial screen and a menu pops up... that won't work either....
Nor the two methods where you dial some numbers and it asks you for the code... so...
Do I have to go back to stock??
I am running on CloudyPro 2.1
Thank you.
Hi all,
I´ve just changed networks on my UK international i9300 Samsung Galaxy S3 so I can use a H20 wireless (AT&T network) SIM.
I tried a few different modems via the GetRIL app, but couldn´t get any to match. I then used GalaxSim Unlock to unlock the phone. The IMEI was temporarily removed but I restored the original modem via GetRIL and it appeared to be unlocked still.
I can now dial with the phone but the only difference is the keypad tones fail to work during the call. When dialling, the numbers come up on screen correctly and make the normal keypad tones. The problem is during the call when an automated line will ask for numbers to be input. They will come onscreen but make no noise, so the other end considers I´ve not entered anything.
There are no settings available to alter, I´ve tried a reboot etc. but nothing has helped. Í´ve had a look on Google but I can´t see anyone else who´s had this problem. Any ideas?
P.S. It is possible the RIL/modem works for texts, calls but isn´t quite the right one to produce DTMF dial tones?
