Sim locking. hello i have the samsung SHG-G600 and everytime i put my sim in it works fine, it starts up and doesnt ask for a pin, but when i put my mates sim in it asks for a sim code, but my mate doesnt have a sim code on his sim. is there a way around this or how can i fix this problem? thanks.

well sir I also faced this problem.the sim you put in your phone had sim lock .you must had put sim lock key 3 times wrong .the phone is asking you the PUK code .ask the customare care for it.

Dear, u should try 0000 or 1234

hello there....well its quite simple...there is nothing wrong with your phone ...its your SIM... if it is asking for a PUK (Personal Unblocking Key) code...call your subscriber and ask them for PUK code,entering this code will reset your sim
if u keep entering wrong your sim will be damaged so call them
If the error message is saying sim damaged call them and ask for a "sim replacement" you will get a new sim while you will retain the same number ,however you will lose the phone numbers and other data stored in sim,this can be free but it depends on the company and how 'customer friendly they are
Hope this helps
Cheers

hie dear,
only the network service provider can give u the puk code.
u need to call the customer care from any mobile ,same as of ur network,
talk to customer care executive, he will ask u to give the sim card number, a 16 digit number written on one side of the sim, then the customer care executive will tell u the puk number.


bunty

i have a samsung sgh G600 and it from uk and i live in India and when i put my indian sim it asks for network lock

go to the store and ask for it

try to restore to factory settings
save all your files on a computer first

I have just tried it with my new locked to orange g600 and it works fine on all networks.

1-Turn on the phone without sim card .
2-Pull off the battery cover and insert any non-accepted sim card (without turning off the handset)
3-Do full reset *2767*3855# , phone will reboot and goes to Menu .
4-Customize Sp-lock code *7465625*638*00000000*00000000#
5-Unlock your phone with new SP code #7465625*638*00000000#
6-Enjoy G600 unlocked
if it doesn't work after step 3.. try changing the 'non-accepted' sim card that ur putting in..
eg if you are locked to vodafone and you try this method and use an orange sim card and it doesn't work, try using a o2 sim or even virgin :)
its easy good luck
