Thanks for the feedback. Most valuable.
I think what I'll do is try to do a technical evaluation. Integration to OVMS firmware and server should not be hard, and it is definitely worth investigating. I'll let you know what happens, but it will be a couple of weeks before I can get the SIMs for evaluation and setup on the USSD gateway.
If it does prove (a) reliable, (b) easy to provision, and (c) workable accounting wise, then my leaning is towards having this as the standard offering (by default). Of course, still offering install-your-own-sim, SMS and GPRS.

And it is not that the current setting is unreliable, in fact once it is setup correctly it is very reliable. So anybody can choose the tradeoff of a one time more complex setup for less monthly operational cost.
