Use-Case & Content Guidelines

Marketing Content Promotional messages must contain header advertisement (e.g., "(광고)", advertisement in Korean) and footer with STOP information (e.g., "수신거부" in Korean and opt-out-number)
Encoding Scheme Korean networks support character encoding EUC-KR. Delivery of Chinese characters is not guaranteed. 
Simple Message Length
 		Message length is 140 bytes (140 characters in GSM-7 or 70 characters in Unicode), including the leading text (see Message Content above).
Concatenated Messages

As known as LMS in South Korea, customers can send text messages with up to 1000 Unicode or 2000 GSM characters in length as a single text message.

By default, LMS is not supported and concatenated messages may be trimmed or delivered with different parts, and split parts may not be received in the correct sequential order.

If you need full LMS support to all networks in South Korea, please reach out to your account manager.
Message Content

Every message will automatically have either of the following leading text added for delivery:

  • "[Web 발신]" - Meaning SMS sent from web
  • "[국제발신]" - Meaning SMS sent from abroad

For LMS, the first 10 characters of the content may be set as the message's title.
