GPS trackers for tracking multiple cars?

Question

satellite navigation

Please tell me cheap GPS trackers so that the location of the company's cars is transmitted via SIM card. You just need to see on the map where the cars are now (with a frequency of once every 5-10 minutes), and, ideally, where they have been in the last 12 hours (at least).
No special functions are needed - let it be simple and cheap. The main thing is that you do not need to reboot. Let it work from the batteries of the cars themselves (but the built-in battery is welcome, in principle, or some system from the discharge of the car's battery - just in case).
