I'm probably way out of date here : I remember seeing a prefix you could dial from your mobile phone to reduce call charges 007,008 or 009. Any ideas or does anyone know of a new and easy discount prefix for calling UK on a thai AIS mobile?

Try 008. There is a 6 baht/minute promotion running right now to several countries. (Note: the mobile phone number in question must be opened to allow making international calls.)
