A flash SMS is a type of text message which appears directly and completely on your mobile phone without user action.
Use cases for Flash SMS
- Emergency notifications
- One-time passwords (OTP)
- Time-critical communication
- Any other type of highly important SMS messages
If an operator or mobile phone does not support Flash SMS the message will still be sent as a standard SMS. In the event that multiple Flash messages are sent, it is important to keep in mind that your users can only see the last message they receive.
How to send Flash SMS
Flash SMS can’t be sent directly via the Darbird dashboard. You can send Flash SMS through our API by classifying the message as ‘type: flash’ in the call to the API. More information on how to do that can be found in the SMS messaging section of our developers website.
