Planning a trip to various eastern european countries like Slovakia, Romania, Hungary and Bulgaria, I am thinking of taking some bluetooth trackers like Apple AirTags, Samsung Galaxy SmartTags or Tiles with me. Main reason is kind of "emergency anchor" when someone of our group gets lost in a crowded place. Of course we'll do all other traditional precautions before...
All systems have pros and cons, but all of them rely on other users with mobile phones around. So far I could see Apple users are widespread in Slovakia (25% market share of Apple in Slovakia), but not that many in Bulgaria or Romania. But would there be a helpful amount of users for Tile or Galaxy SmartTags in these countries? What could be helpful tracking system in these regions?
