Develop dedicated GPS/cellular luggage trackers

I'm not interested in bluetooth-only trackers such as AirTag or Tile. I'm only interested in GPS or maybe cell tower trackers, or a combination of bluetooth and/or cell tower and/or GPS. GPS is definitely preffered. Has anyone had any luck with these products? With the traditional bluetooth products, not only would thiefs have to have the right kind of phone, I'd have to have that kind of phone too, and thiefs have to have bluetooth enabled. For example, with airtag, I need an iPhone, the thief needs an iphone, and he needs blueetooth enabled. • Jiobit Smart Tag • Tracki GPS Tracker • LandAirSea 54 GPS Tracker • GEGO GPS Luggage Tracker • Family1st Portable GPS Tracker • PAJ GPS Suitcase Tracker • AirBolt GPS Tracker There's also products called "Asset Trackers" Like Cube Tracker They have a Sim or esim and there is monthly subscription but I think it might be a good idea. Not sure if they work in most countries, hopefully they do since it's presumably satellite, not cell towers? But not every sat network is global... Unsure how they work through a pelican case, through a steel car body, inside a building, inside a parking garage, inside a shipping container, etc. Probably not great. But if your shit makes it into a concrete building and/or a shipping container, it's probably too late anyway. I've also seen trackers for like snowmobiles that claim they need to be exposed to the sky. If that's the case, this isn't going to work, theyre gonna be inside a suitcase. Also, luggage is sometimes lost due to incompetence. I plan on using a GPS for other things, not just luggage Thank you!
