Supplied the IMEI number of a mates phone to my cousin who has a mobile repair and unlocking business in town. My cousin sent a server request for an unlock code but it came back a few days later as 'No Code Found'. Can anyone shed some light on why this would be the case? My cousin just said that it does happen on a rare occasion. The phone was bought second hand so my mate can't contact the mobile operator to have it unlocked. It's working fine on Vodafone but he wants it unlocked to use with a different network. (">
