Hello,
This is SureM.
Today we would like to introduce SureM South Korea traffic delivery using International Prefix (route).
Firstly, it is crucial to send the traffic inbound by adding prefix in front of the Sender ID for all International traffic.
The prefix sender id SureM can provide is 009 or 00777.
Secondly, each prefix features are same as below
1) 009 prefix
– header [援?젣諛쒖떊] / [援?쇅諛쒖떊] or Sent from Overseas
– SMS : 1~90 bytes (1~45 characters)
– LMS : 91~2000 bytes (46~1,000 characters)
– Encoding : EUC-KR (only English or Korean)
2) 00777 prefix
– header [援?젣諛쒖떊] / [援?쇅諛쒖떊] or Sent from Overseas
– SMS : 1~140 bytes (1~70 characters)
– No LMS supported
– Encoding : UCS-2 (korean, chinese, japanese etc including english)
Also, each Operators may send different header depends on the situation and if any special characters beside available ones in keyboard, you will be likely charged as unicode.
