Wanna know who is calling? Track anyone!

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)

It may not work in all phones, but with standard its working ;)
