Free send sms software for pda

This system extension allows you to send short text messages from applications supporting the "Send..." command, for example the built-in Contacts, Memos, Calendar, Tasks.
Compatibility
Tested on Treo 600 and Treo 650. Should work on Treo 700p as well
Theoretically, it can also send SMS on other devices if there is an SMS-handling application registered in the system.
Usage
Select "Send..." from the menu
Select "SMS"
The text is pasted into the message, now you can fill in the "To:" field and click Send
Limitations
It can only send Text, exactly like if you typed it yourself. The receiver will also get the data as text only. For Memos this is obviously not a problem. For Contacts, Calendar events, and Tasks you can use RNS: TreoVCardReceiver to automatically transfer the incoming data into the associated application.
The amount of text is limited by the medium, you cannot send more than a few hundreds of characters.
And of course no binary data (it would be hard to find the binary file to match the size limit anyway).
What about the built-in Messaging/MMS?
On the Treo 600 you can send this kind of data with the built-in MMS application (call "Send", pick "MMS") - but there is no option to select SMS instead of MMS. On Treo 650 it is called "Messaging" instead of MMS and it is even worse (all you get is: "The messaging application does not support this type of item.").

Nokia Sensor is a spontaneous, sociable application for spontaneous, sociable people. With Nokia Sensor you can create your own personal pages - called a folio - on your phone. Then you can check out the folios of other Sensor users nearby, exchange messages, and share files.
Connect on the spot
Nokia Sensor uses Bluetooth wireless technology, which means that it works within a circle of up to 10 meters around your phone.
When other Sensor phones come within this circle, your phone can sense them and you can see their folios and send them messages. As soon as you step out of each others circles, you are no longer able to communicate via Sensor.
Connect for free
Because phones running the Sensor application communicate directly without going through an operator network service, communication is free of charge.
However, if you send SMS or MMS messages to other Nokia Sensor users, regular operator fees apply.
Bluetooth technology settings
In order to communicate with others using Nokia Sensor, the Bluetooth technology settings (in your phone and in theirs) must be turned ON and set to shown to all.
System requirements:
- Nokia 3230, 6260, 6620, 6670, 7610, 6600, 6630, 6680, 6681, 6682
