<br>I have not heard that any USSD-gateways are available for external customers, and if it exists, I'm sure there is a cost of using.<br><br></div>However the M2M-marked is growing, and I think USSD is a good candidate for fast transfer of small amounts of data.<br>

I'm about to start work on the USSD protocol we had previously discussed. Just a technical evaluation at the moment, to see if this is feasible.<br>
<br>
The <a href="http://www.openvehicles.com:6867" target="_blank">www.openvehicles.com:6867</a> development server may go up+down quite frequently for the next month or so, as I try different things. If anyone is using that server for their car, I strongly recommend you switch to <a href="http://tmc.openvehicles.com:6867" target="_blank">tmc.openvehicles.com:6867</a>.<br>
<br>
Thanks, Mark.<br>
