Number format

How do I write Thailand numbers for a bulk SMS list?

Write numbers for Thailand in international format: the calling code +66 first, then the national number. If people in Thailand dial a domestic trunk prefix such as 0 at the start, leave it out after the calling code. A number written this way looks like +66 8 000 1234. Spaces and dashes are fine; the console removes them when it reads your list.

Language

Which alphabet do recipients in Thailand read?

Most recipients in Thailand read Thai. Text written in Thai is sent in UCS-2, so one SMS segment holds 70 characters (67 per part when split), and a 140-character message costs two segments. Messages in English or other plain Latin text fit 160 characters per segment.

Timing

When is the best time to send SMS to Thailand?

Thailand keeps one time offset, UTC+7, all year. Local 9:00 to 20:00 in Bangkok is 02:00 to 13:00 UTC in January. The scheduler uses the time zone of your own browser, so convert the local hour you want before you pick it.
