If you need to call to Thailand from belgium or Netherlands, I can recommand a pre-paid phone card from
www.pangea-telecom.com
I use it for a long time to call my gf and it's far cheaper than other com.
2 days ago, I had the good surprise to hear that for 5 euro, I could call 86 min (if I call a free number in Belgium) or 104 min (if I call a local number) ... It's almost half the rate than before, so +/- 5 or 6 euro cents for 1 minute.
Just check for Maxi Call. But I have not seen yet on their website the new rates. Anyway, good news

From belgium, it's possible to pay more than 1 euro for one minute if you use the national operator, and 20 times less wit a phone card... God!
Obviously, the connection is not always so good as they use Internet, so it's local call from Belgium to their platform, then Internet (probably something like Skype), then a local call again in Thailand, but for the difference of price, i don't care
I remember some phone invoice of 300-400 euro before ... I see the difference on my bank account.
I must precise that I am absolutely not involved in this company, so don't take it as an advertising, but just an friendly advice ... just because national operators take us too often for ATM machines too... and more than BG's, believe me
