Simple Internet Fax or SIF is software for Palm PDA with PalmOS+. It is used to send Fax, emails and SMS to mobile phones anywhere in world and voice messages to regular phones and mobile phones in North America. But you need the external service provider’s connection for voice messages.

This software allows you to send voice messages without the voice recorder. The user just types the message in his Palm PDA and application coverts the text message into voice message automatically and then sends to the desired phone number. This feature of text to voice conversion can prove boon to people with speaking problems. It also allows sending voice messages from PDA or PC without using any external device like microphone.
