I heard that kiteboard bags get "lost" often at airports and was wondering if there's any reliable GPS trackers I could use. I want one that allows you to insert your own SIM card/cellphone chip, not those that oblige you to use their chip and pay 20 USD per month. That's a rip off!
I'm not interested in tracking my session. All I want is a cheap device that can track where my kiteboard bag is for 2-3 days in case it gets stolen. And if I can attach it to my board during the session in case I loose it, even better.
