Hi, i have some problems with No Sim Card detected on Samsung Galaxy S III I9300 from T-Mobile (Austrian)
Firstly i unlocked the phone at the shop and was really unlocked on all sim cards but than i did a factory reset and the phone no longer detects sim card from other carriers, it only detects sim card from T-Mobile, It dosen't even shows the menu when you turn on the phone for network unlock.
I tryed using those secret codes to show the network unlock menu but they didn't work since the phone was updated to 4.3 firmware.
So i followed this guide on androible downgrade-galaxy-s3-i9300-android-4-3-android-4-1-2-jelly-bean-firmware
To downgrade to 4.1.2 firmware along with provided modem file. The secret codes now do show menu's but when i click on UMTS RF NV it says it's not supported.
Also instead of downgrading to T-Mobile 4.1.2 Firmware i downgraded it to Orange 4.1.2 Firmware hope that dosen't effects it in anyways? Phone otherwise works just fine IMEI Number shows OK.
I tryed 2 different SIM cards from orange none of them worked, it only detects SIM from T-Mobile.
To recap it all agean: I wish to unlock this phone so i can use different SIM card's but the phone is on NO Sim card, emergency calls only but when i insert T-Mobile Sim it works, Also there is no Network Unlock Menu shown durning turn on or reset since i already Unlocked the phone once with a code. Does anyone has any clue how to fix this or unlock it without rooting the phone.

i have rooted my international galaxy s3 GT-I9300
and installed voodoo sim unlock
when i open the application it says
sim lock:inactive
so is my phone factory unlocked and will it run any carrier sim card?
Basically yes, that's what it says.
so phone is unlocked right?
Again, yes.
thankyou very much
I also use voodoo sim unlock it says network inactive but when i insert a diff sim it didnt work. Untill now my sim is locked. Try to put other carrier so you will see if its really unlock. Hope someone fix voodoo sim unlock,coz thats the reason i root my phone.
I bought a used galaxy s3 that seems fine except that i can't get it to work with my sim card. I always get the searching & not registered on network when trying to dial. The sim card works fine on other phones. the phone is running android 4.3... Any idea of what could be the problem and how to fixx it?
Are you sure that you phone isn't sim locked?
If it were sim locked you would get a request for the unlocking code at boot. Most likely the phone has been tampered or broken, either wrong modem or efs folder corrupt.
Search and read for the available fixes.
I'm now SIM locked after flashing a modem and can't figure out how to reverse it. I have the international model and it was never SIM locked before (a week after available). I flashed RR and couldn't get it read my SIM card so I flashed a modem. Didn't work so I restored a backup (strangely only gives system and data option) and now it shows optimizing apps every boot and says I am SIM locked. Any ideas?
I have this problem also its asking for PUK ive tried 2 different sims with there codes not working
I recently unlocked my Galaxy J7 Sky Pro from the tracfone carrier (called them, got two codes, put them in and device said it is now unlocked).
Now when I try to insert a different sim card the phone seems to have no service, even though the sim card is recognized (asks me for the pin and logs in properly). In fact that sim card is a prepaid european one, from the german carrier O2, but since J7 Sky Pro can do LTE connection I though that should work fine?
What do you guys think, is there something I could do to fix the issue?
My exact model is:
SM-S727VL
And android version is:
6.0.1
One kind of annoying thing is that even though I unlocked the phone, it still shows the tracfone logo on startup. Maybe the firmware is preventing the european sim card to connect to a tower? Is there some "international" version of firmware I could update to to make it work?
Thanks for any suggestion!
