Currently in North America, I'm trying to find a way to track my tour position through GPS so loved ones can monitor my progress. There are GPS tracker I'm aware of, but if I were to get one I would prefer one that doesn't require a subscription to service or be too outdated that was a decent one in it's 2G network days. What is most effective? Easiest to operate? Holds a decent battery life? I just want something that I can easily look up online or text the location every few hours. It's become harder than I thought to find this. I wouldn't know if it would cause issues at an airport say I stow it away in my bike luggage so it doesn't go missing on a cross ocean tour.
