was it you who purchased a motorhome / campervan ? ? ?
is it for that ? ? ?
the better ones are subscription based, you can buy them with a sim holder, so it uses the mobile sim signal
this one charges 20 quid a year, uses date which they say is fairly cheap

50 quid for the pair
many in the old VW t4 scene, used to get a old phone ( put a pay as you go sim in it ), wire a charger in from a 12V feed from the battery, hide it all behind a panel, you can track that then, apple even do " find my phone " , yes they can cut the battery, but the phones battery will last a while
depends on what you want to track and how much you want to spend
