I think you're going to want to talk to some carriers about supporting this project. You might start by checking out AT&T's Emerging Devices site, which has some great information about device certification, project plans, and business models. The link is: www.att.com/edo.
You could also consider ordering a Dev Kit from this M2M.com site: https://att.m2m.com/devkit/ .
Thank you for your reply. I have spoken with AT&T (Industry and Mobility Alliance Program Manager). He directed me to an individual in development. I have also spoken with Sara Perry at Jasper.
We have engaged a design service firm for product development, with production units in November.
You have confirmed and been a help in our direction
