I've been told by many people, that one of the biggest problems with OVMS is the cellular providers. It is a hassle to maintain a pre-paid card, and the providers keep changing the rules. Particularly in the USA. Could you let me know (with figures in US$, approximately ok, please): What country are you in? What cellular provider and service do you use? How much do you pay, up-front for the SIM card? How much do you pay, monthly for the service (SMS + Data)? How much do you pay, per-MB for data? Long-term viability - do you think this is still going to be possible in a year or two? Anything else relevant? Just reply to this email, on the mailing list. I only need 1 report for each provider, so if you see someone else reply to the list for your provider you can ignore this. Thanks, Mark.
