May I "bump" this thread to repeat the question from 12 years ago? Surely some of you know the best inexpensive ways to call overseas, especially to U.S.
For years I dialed 1544, followed by 009 and could talk to U.S. via CAT for 0.9 baht / minute. But apparently the money I had in the 1544 account expired after 12 months or such. (I'd been using Facebook Messenger to talk. But sometimes I want to talk to someone without Facebook!) CAT offices are hard-to-find upcountry.
Does anyone know the rates to U.S. via 009, 008, 005500 prefixes etc.? I suppose the info might be on-line but websites here are not always organized perfectly.
