Trying to work out ways to provision OVMS modules without SMS.
One way is the new DIAG port SETUP mode. But, that requires a RS232
connection to the PC (not so easy nowadays, with a USB-RS232
adaptor required for most laptops). Also kind of messy for v1 modules.The main reason I'm thinking about this is for the globalsimcard
provider I'm working with. They can provide SIM cards that work
globally for data only, with pretty good rates. Cards are good for
12 month validating and can be renewed for another year for less
than US$10. Monthly cost should be US$1 + data, hassle free, and
data should be less than US$2 for most providers. If we can auto- provision these, then setup should be to configure the provisioning
information as you want, on the server, then just plug the SIM in
and go.Every SIM card issued has a defined prefix in its ID. I'm trying to
find out of the globalsimcard prefix will always be the same, and
will always differentiate these from others. If so, then we can
auto-provision based on SIM ID as well (without even needing the
OVMS-AUTO phonebook entry).What do people think? How easy would it be for people nowadays to
create a phonebook entry on a SIM card?
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.
