[Q] SIM lock - Galaxy S III Q&A, Help & Troubleshooting

Few days ago I flashed Hypermax V9 ROM for the international version of the s3...my phone worked fine till yesterday.Suddenly it restarted,and when it booted to the lock screen it asked me to enter SIM lock network PIN? Does this mean my phone is locked? I bought it and it was simfree,I rooted it and used this ROM it worked very well until now..I tried to flash stock firmware with Odin,which I downloaded from sammobile but its still locked and asking for a PIN.Any solutions?

SIM pin is very different to network unlock code, try another SIM card first.

I tried two different sim cards,its all the same,still asks for the code to unlock...in the status bar it shows like I have full network signal,but when I pull down the notifications panel it says Emergency calls only...The phone worked ok on this sim card for two months now,why would it just ''lock'' itself suddenly like this?

what is this error mean?

Hello, I was bored bc of hot weather and I thought to make an operation on my old GT-P1000 because its sim card module didn't work with a simcard which can work other phones and other sim cards are working on p1000. I thought there is a problem bc of custom Rom. Than worked on few roms. And now, I m getting this warning pic and can not open tab as download mode or recovery mode. Let's solve it together. Thanks.

Nobody know what is that mean?! Please heeelp
I think your phone is brick.
I'm not so sure that it is..
because its sim card module didn't work
Click to expand...
Click to collapse
All the picture is showing is there is no connection between the phone and the sim card
If the phone was bricked , he wouldnt even see that picture, it would be stuck at splash screen
then again
can not open tab as download mode or recovery mode

Click to collapse
this is a sign of a bricked phone..
Is the simcard in the phone/tablet/wtfe ?
if it is in the device, then you answered your own riddle
the module to read the sim card is broken

[Q] Only ONE sim works, wtf?

Guys I use Qmobile Noir A10, I m in akistan. Since I have bought it (as used phone with warranty) I was using "ZonG" sim card. But now I wanted to use other SIM but what? No network available, used two other sim card which work flawlessly on other phones but no signals in my phone only.
I have inserted other sim card "Mobilink" and checked balance got this error:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
When I see available networks it only shows zong:
This is status for Mobilink (or any sim card):
Status of mobilink from engineering mode:
This is status for Zong:
From eng. mode:
I have switched many ROMS but never checked nor used/inserted other sim card BUT I remember once I checked other networks and it showed all others but now when ever I check only damn zong available. I changed ROM but no luck. Once when flashing BumbleBee ROM it wiped by IMEI and I again fixed it by CDS information(matching with box one). This is what my problem guys, only one sim card. What the heck. Need help please.
My phone hhave forum here "Micromax A110" but its kinda inactive so posted here. It is MTK6577
Fixed it my myself. Some mod close it please

[Q] What does this SIM lock mean?

Hi all, so I just wanted to ask what my SIM lock status mean? I can use phone with all operators and all sim cards but phone shows not 0 but 5 on all information (Network, network subset...). But is my phone fully unlocked or it's just somehow modified?

As i saw in this thread, it seems you have completely no simlock. If something is locked, there stands an x first in the entry. the numbers are the left try's to unlock. if there stands a 0 you have no chance to get a simlocked phone unlocked by entering the code from service provider. 5 is standard amount of trys to unlock sim.

Can't get any signal after the phone was locked with Android device Manager

Hi there,
A friend of mine lost his phone a few weeks ago so he locked it via android device manager.
Luckily the mobile was found and is up and working now (no data erased, just got a new sim from the carrier as the previous one has been locked too) but it can't get any signal (he is on giffgaff if that matters).
We tried to swap slot in the sim tray with no success. All I can say is his sim is properly recognised on my iPhone and my sim does get the signal when put into his xiaomi, so we can possibly exclude a hardware failure.
Curiously enough when he logs himself on Android device manager through the app all options are greyed out, but it does not happen if he uses the web version (all options are available). Might this be somehow related to the phone's inability to get the signal?
He is currently on MIUI GLOBAL 8.0.1.0.0 stable (no Roms were flashed since he bought the phone)
Any help will be appreciated!
