What do you use? I’m looking for as many of the following as possible:

• included battery, preferably rechargeable from the motorcycle’s own battery, meaning
• negligible idle consumption
• EU coverage, supporting 3-4 constellations
• 4G+, i provide the e/SIM (i.e. no included plan unless it’s grrrreat and cheap af)
• small form factor (for a naked bike)
• privacy-respecting app (preferably not relying on AWS, Google Maps, etc) and/or website
• motion-detection/geofencing
• cheap of course

I had a cheap one from eBay but the chinese-quality app would sometimes lag hours behind - not useful for an eurotrip.
