[Q] problem with unlocking - Galaxy S III Q&A, Help & Troubleshooting

Can someone advise me with my unlock problem
The phone is a samsung G3, on FW 4.3
I had tried the online free guides using codes, but his didn't work and I was advised to purchase third party unlock code, which I have done,
I have two sims to try out,
my vodafone contract, ( emergency calls only and not registering)
a new tmobile sim ( emergency calls only, registered)
On both of these sims there is no prompt to enter an unlock screen on the phone.
I have tied these
#7465625*638*UNLOCKCODE#
#0111*UNLOCKCODE#
On both occasions I get the message ( connection problem or invalid MMI code)

Does the phone connect on the network to which it is locked? It sounds like you have efs problems, not just sim lock.

[Q] PUC code related to unlock menu?

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...

Unlock code while booting

I hav a HTC Mozart orange... When using a different Sim card, it asks for an unlock code.. Wat do i do? ?

you have to go to the network provider of the phone and and ask them for the phones unlock code. You will more than likely have to provide them with the IMEI number of the phone. This can be obtained by dialing in *#06# and it will show then. If the number that is shown on the phone is 17 digits, you just leave out the last 2 digits. Once you have the unlock code, you simply place the sim card into the phone, make sure its a different nettowrk than default. The phone will then ask you for a PIN code, this is the unlock code that the network has provided you. Simply enter that in and your done.
I have done this on my own phone, and am now running it on a different network, so it always shows up a triangle on the very top of the screen, this simply means that its roaming. This is because its running on a different network than stock.

Sim card not registered?

Hi guy's, have a UK SGS2. It's rooted and running Criskelo ICS rom. I've recently been in Brazil for 6 months, my phone worked fine over there. I've come back to the UK and got a standard Vodafone PAYG sim card. When I try and use it the phone says "not registered on network"
The sim card itself is fine as it works in my old mans SGS2.
I have wiped the phone and installed the standard software and it's still the same.
Anyone got any ideas what could be up?
The phone could be network locked (sim lock)

That's what the guy on Vodafone web chat suggested.
How and why would it get network blocked?
The phone was originally on the 3 network. I bought it 2nd hand about 1.5 years ago and it's been fine on T-mobile ever since.
If it is sim locked, is there a way to unlock it?
You can unlock with:
https://play.google.com/store/apps/...sImV1LmNoYWluZmlyZS5zZ3Myc2ltdW5sb2NrY29kZSJd
It's free on google play.
I don't think it's sim locked, I can put any chip in it. It doesn't ask me for an unlock code.
I have run the sim unlock tool. The code it came up with is 00000000
When you go into the network settings, it shows all the service providers. every provider I click on says "can't register on the network"
I'm wondering if i've had some sort of network update in Brazil that's screwed it up?

I'm sure its something to do with being abroad as i've read about someone that had the same issue when they went from China to Denmark.
If I go to settings - phone it says...
Network - Unknown
Signal Strength - 103 dBm 5 asu
Mobile Network Type - HSDPA:9
Service State - Out of Service
Roaming - Not Roaming
Mobile Network State - Disconnected
My Phone Number - Unknown
IMEI - the correct number, I checked
The fault isn't with the sim card itself, I can use it in other phones and I can save a contact to it in this phone.
I'm wondering if some of those network settings I had from the Brazilian phone company's have messed something up.

[Q] Help with getting network unlock screen on Samsung Galaxy Discover SGH-S730M

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!

I NEED HELP Network Issuse

This phone is locked and can not be unlocked.. I bought a phone on ebay plugged my Sim card in booted up and was prompted for an unlock code. I then called my service provider and he said he could not help with that but if I entered the wrong code in 10 times the phone would then ask for a puk Code. Well we completed this but it never asked for the PUK code. Instead, it gives me the message "This phone is locked and can not be unlocked"..
I have called the original service provider and the maker of the phone. AND WAS SENT TO AND FRO FROM ONE TO THE OTHER. I still have a locked network and "emergency calls only" at the bottom of the screen and "network locked" in the task bar. I found a website that gave me instructions to get to the screen where you can unlock the network by pressing 2945#*850# in the dialer which gives you 5 options;
Network unlock - where I get the same message again: this phone is locked and can not be unlocked
Service provider unlock - your phone is not personalized
Network SubSet- your phone is not personalized
Corporate- your phone is not personalized
SIM/USIM-your phone is not personalized
I really need help LG G3 850
Ps. when I called the original service provider and gave them the IMEI number she said the phone is clean and not blacklisted or any thing. Just FYI
