As I was trying to say before when Mr I Know Everything about Thai mobile contracts chirped up (note he's banned now), the package I get is only ever advertised in Thai - I can't remember the exact deal but its not normally advertised at the airport counter or on the English version of their website. It was my ex who pointed it out to me - I think its about 299 baht per month with unlimited internet but it does throttle back on speed after so much is used. Whatever, its always been enough for me - I'm not a teenager with a phone implanted in my head.
Where've you been by the way? Thailand?
