Can you though? Every time airtags come up here someone is like "you can get GPS trackers already! they're cheap!" but I actually looked and actual GPS trackers that don't require a subscription or have various other flaws seem to be very difficult to find.
If there's a GPS tracker that uses an eSIM and isn't sketchy af and has decent battery life and isn't £100 let me know! I would love that for my bikes.
