This is the first feature I thought of after ordering my v2 OVMS. SMS  
is so expensive on my regular cell phone that it seems prudent to  
find a way to avoid it altogether on the OVMS. Your mention that a  
provider offers a data-only plan fits right into my line of thinking.

I have not even started yet, but I had planned on looking at the  
firmware source to see about ways to perhaps compile in these  
provisioning values. I realize that I am probably one of only a few  
customers who could deal with compiling and loading firmware, so my  
potential solution is certainly not a universal solution.

I also have access to USB serial solutions, so I'd be interested in  
non-SMS provisioning solutions that require RS-232.

As for SIM card editing, I was planning on recycling the SIM card  
from my RAZR v3. Assuming it will still power up, I anticipate that I  
could make the required entries and move the SIM card to the OVMS.
