International call costs

The cost of international calls depends on which prefix you put before the number you are calling. If you hold down 0 to get the + symbol (and in some instances dial international numbers stored in your phone's address book) you will be charged the dtac plus premium rate. The cheaper 004 standard rate will be charged if you dial 004 before the country code when making a call.

Other phone companies in Thailand operate international services using different international access codes, and using these instead of + or 004 will mean that you will be charged at different (sometimes cheaper) rates.

International text messages cost 8.56 baht (approx. 26c) to most countries.
