Tried using galaxsim but it allows me to pay thru credit card after hitting unlock. Where can I find an app that's free to unlock?

Follow the link on this thread I used it and have had no problems since.

It's the same application that I used. It leads me to the galaxsim pro unlock which is a paid app. Ive installed galaxsim and after hitting unlock it says that unlocking will only be successful if I download the paid galaxsim unlock pro.

Did you download thespecific file?

The version of GalaxsimUnlock from XDA threads is free, only the play store version one is to pay

Uninstall anybpreviuos version of the app and use the one from the link I sent you, if that still fails I can send you the apk file in haven when I get home.

Very much appreciated. Thank you! Btw, what's the difference with your apk file than the one that can be downloaded to market?

Need help Orange PL

Hi,
I have a problem with my I9300 (Orange PL).
I'm looking for a solution on the forum but with no positive result.
I have the latest Omega rom. Voodoo and GalaxSim Unlock from PLAY store did not see the EFS files. GalaxSim from XDA writes that "Your device is unlocked" but it is not true.
Maybe I need to do as some suggest downgrade to 4.04 or 4.1?

The app says my phone is unlocked when infact it's locked to Three UK and asks for a code when a foreign SIM is inserted

You have probably installed one of the newer modems and you have the new EFS format. I believe that one can not be unlocked with this program. Read the thread on EFS and in case you have an older EFS you can restore that one (and also an older modem), unlock the phone and then upgrade with the unlocked EFS to the new format (by writing the new modem). Take backups of the EFS at all steps.
