A boolean switch indicating whether the current short message should be sent as a data message.
Ordinarily, there is a size limit of 255 characters on the length of the message that can be sent. If SendAsData is set to true, a longer message of up to 64KB can be sent. Note that if multiple recipients are specified in RecipientAddress, the adapter must issue separate requests for each address if SendAsData is true.
This property is not available in the Receiver.
