Unlock code i need to un lock from tesco to voda phone

SOURCE: tesco samsung J700

Type *#9998*627837793# Go to the 'my parameters' and there you will find new menu where you can unlock phone.(not tested-for samsung C100)
To unlock a Samsung turn the phone off take the sim card and type the following code *#pw+15853649247w# .
Java status code: #*53696# (Samsung X600)
If you want to unlock your phone put a sim from another company then type *#9998*3323# it will reset your phone. Push exit and then push 7, it will reset again. Put your other sim in and it will say sim lock, type in 00000000 then it should be unlocked. Type in *0141# then the green call batton and it's unlocked to all networks. This code may not work on the older phones and some of the newer phones. If it doesn't work you will have to reset your phone without a sim in it by typing *#2767*2878# or *#9998*3855# (not tested)

Hi your only option is to call your phone service provider, I've explained more on this page http://www.bukisa.com/articles/19406_puk-code

only the phone service provider can give you the code.

the code you're given is meant to be a one time open network, where you basically reset your phone's network settings. If you buy a cheap PAYG phone from the carphone warehouse, you can use any sim card you want as they're all open phones :)
