CM's Country Regulation Interpretation
While for some operators the option for dynamic sender is still open, our experience has been that the more reliable option is a shortcode in the 6xxxx range (as appointed by the telecom authority). The addition of cost information to the message body is deemed necessary for customer protection.
Direct connection: Dynamic senders are not allowed. All senders will be changed to a shortcode or longcode.
Dynamic senders are possible for CellCom and UMobile.
For Maxis and Digi only certain numeric senders get through (not reliable).
Direct connection: "RM0.00 " (7 char) is added to the message body to indicate that the subscriber can opt-out for free by replying to the SMS.
It is not allowed to send free messages for the promotion of a premium service.
There are restrictions on sensitive content like gambling, politics and religion next to those that prevent abuse (spam, phishing, etc).
Only Celcom supports Handset DLR. Other operators in Malaysia return SMSC DLR.
All Malaysian operators except Digi supports Concatenated SMS.
All Malaysian operators support Unicode.
CM has indirect access to an MNP database of Malaysia.
CM has direct connections to operators through a local partner.
CM has access to 2-way solution via dedicated shortcode.
