I unlocked my LG Optimus One P500 which was locked to Three

I unlocked my LG P500 which was locked to Three and the phone accepts other sim cards but when I put my 02 and my Lycamobile sim card into the phone it doesn't work because I can't text or all anybody as it says call ended but if it is on roaming the internet just works whereas if I put my Lebara sim card into the phone everything works perfect. Why won't my 02 and Lycamobile sim card work but my Lebara sim card does work in the phone?
