The table columns:
Concatenated SMS:
- MT (Mobile Terminated) messages: The SMS provider supports splitting long (>160 characters) messages into multiple messages when sent from Flex to the mobile phone.
- MO (Mobile Originated) messages: The SMS provider supports long messages sent from the mobile phone to Flex. The message is split up by the SMS gateway and reassembled by Flex.
SMTP to SMS:
- If the SMS provider supports "SMTP to SMS", then e-mail invitations in Flex can be used to send SMS invitations.
Shared Short Code:
- Use a pre-provisioned short code at a fraction of the cost of setting up a dedicated short code. When you use a shared short code, the keyword you wish to use with your survey must be registered both in the SMS extension in Flex and in your SMS provider account.
Dedicated Short Code:
- Use a dedicated short code for branding and recognition purposes. Keywords only have to be registered in the SMS extension in Flex.
Dedicated long code:
- A dedicated international long number that can be used to access the survey from several countries. Keywords only have to be registered in the SMS extension in Flex.
Web site - the web site of the SMS provider.
