So on my phone, I have a sim card pin setup when you turn it on. After you incorrectly enter the pin number 3 times, it locks you out until you call your service provider. So I called my service provider, who gave me a PUC (pin unlock code) code and told me that there should be an option that says enter your puc or something like that. But there wasn't, so the assistant asked me to enter it in the emergency dialer. When I hit dial after entering the PUC, it said that it was not an emergency dialer. According to the assistant, it should have automatically accepted the code, bringing me to the issue of the unlock menu. On stock, when you enter in *2945#500#, it should automatically accept the code, but on custom roms, it doesnt. I believe the two issues are related, but I would like to confirm this first. And maybe this might be sort of a request to the devs asking if they can include the unlock menu (i have read that it is not implemented as it is useless to most people) since now I have to get a new SIM card (not that it is the devs' fault, but it would be useful for people like me).
Or you could borrow a dumbphone and use that to unlock your sim (unless you get to keep your old number if you get a new one).
I have yet to experience needing a PUC on my sim on this phone on this ROM.

just tried that but it didnt work. probably because my sim card has been locked permanently
if a simcard is locked, than its locked and can only be unlocked by a PUK code.
You can order a new SIM card from network provider, its possile i know if the PUK is locked too because of to many failed trys.
even if i break the code to use the SIM card again, you cant make calls nor use
the contacts on the SIM - the network provider is checking the SIM status and
locks it again.

thanks for the reply.
but does the PUK code have anything to do with the unlock menu or those hidden codes in general? i know that on stock froyo, some codes are accepted automatically in the regular dialer. on custom roms, these codes are not accepted in the regular dialer at all. the emergency dialer did not accept the PUK code just like how the regular dialer did not accept the other codes (such as *2945#500#) and i was told that it was supposed to accept the code.
sorry, i never used hidden menus and dont know if its implemented in android source
or its a extra feature by manufacturers like LG, HTC,Samsung etc.
As i know the PUK is only for unlock the SIM when the chip is locked and can only be entered on a lockscreen keypad.
finally solved the puk issue. on my phone it did not ask for me to input the puk code. then i inserted my sim card in my dad's phone (same phone except running on stock froyo). now it asked me for a puk code. if only custom roms had this functionality of accepting these codes...
Hi all,
After installation of slim bean (File: slim-gt-i9100-2-8-0-official) following all instructions reported on the official web site, I cannot keep active the SIM Card's PIN Code on my phone.
If I keep it active, when the phone goes in stand-by mode and then I go to wake it, sometimes the SIM PIN Code request appears and the radio signal is broken... by the way the phone result not reachable.
Furthermore when the PIN request appears, if I put a code that's not the correct PIN Code, it is accepted and the radio signal come back.
I think that is also important to specify that I have always the "PIN Screen lock" option selected in the security section.
At this time I have disabled the SIM Card's PIN CODE Request but leaving still active the PIN request for screen lock. All seems to be OK.
Someone have some suggestion to fix this problem ?
Thank you in advance.

I've read a lot about unlocking phones over the years. But this is the first time I have actually come up on a feature called "Sim Card Lock" where you enter a PIN to lock a particular Sim card. This feature is unlocked as long as I have my Sprint Sim in the phone. But as soon as I put in, like say, an AT&T Sim the Sim Lock feature turns on and locks. In other words, it has a checkmark where I have to enter a PIN to unlock it. Sorry to seem like a complete noob. But is this the same "sim unlock" many are trying to crack? There must be a PIN that has been coded in that locks down any foreign Sim. If so, it seems like it would be possible to figure it out. Every time I enter the incorrect PIN code, it always says I have "0 attempts left". So I can enter it as many times as I like without locking down my ATT Sim. Anyone know of a way to figure this out. Or is it even possible at all?

I am trying to unlock a Samsung Galaxy Discover phone SGH-S730M. It is locked to Bell Mobility in Canada. I purchased an unlock code for it. My DH is a truck driver that frequently crosses the border so we are trying to reduce the amount of phones he carries
SIM card he is using state side is with ATT. He puts the SIM card into the phone and is getting "Invalid SIM" message. He isn't getting the network unlock screen. We pull the card and try again - same message.
Had him try #7465625*638*# - gets the network unlock screen. He enters in the 8 digit code - gets the error " connection problem or invalid MML code".
Is there any way of launching the network unlock screen without having to reset the phone? All of our kids pictures and things are on the phone and he'd be lost without them.
Any advice would be greatly appreciated!
