I have one from 2008, which I don't use anymore. It speaks NMEA and it sends the data over GPRS. I guess there are 3G devices now. An advantage of GPRS is that it's everywhere (at least in Europe) because basically it's data over GSM. It's cheap. A data only SIM with 2 MB per month per year (yes MB) was 12 Euro per year. But you're not sending many positions and it's few bytes per position. I made a site like gping.io back then. Not enough customers but it could be different now.
A word of caution for any kind of GPS device, phone included. The GPS antenna needs to see the sky, best if a lot of sky. The roof of the car is enough to severely shield the GPS signal. You need assisted GPS then.
