Is there a way to transfer or compare MMC( Mobile County Code ) and MNC( Mobile Network Code ) to 'normal' country codes and operator network codes?
For example if we take Finland, I know that 244( MMC ) and I use the network of TeliaSonera 91( MNC ) and I would like to compare or transform those to International country code ( +358 ) and to TeliaSoneras operator network code ( 040 and 0400 ), is that possible and if it is how can I do it?

Thank, Rampe
