Vietnam: SMS Guidelines
Dial Code: 84
Alphanumeric Sender IDs are supported with registration. Alphanumeric Sender ID registration is required.
The use of generic Alpha Sender IDs is not recommended. Alpha Senders should be directly related to the message content.
Vietnam is a destination that supports SMSC-DLR only, as such positive DLRs are to be expected. Handset delivery reports are not possible.
Please make sure to always refer to our Acceptable Use Policy for Messaging.
For more information on Alpha Sender ID registration kindly reach out to email@example.com.
