Samsung Galaxy s3 unlocking advice required

[gandalf72]

Hi,

I have a couple of samsung galaxy s3 phones I would like to get unlocked. One is on o2 and the other is on orange, what would be best way to get this done (they were bought second hand).

Thanks in advance

there is an app called GalaxSim, available on the play store and xda forums. I think the device needs to be rooted to run it though but again info on xda CF-root is i think the easiest way.
