My experience with the app Burner was pretty good because the app can accept texts from new numbers, unlike a lot of free online phone apps. It’s not free, however.
Look for any of them that wire directly to your battery and don’t need to be charged. A GPS pinger uses very little energy so you shouldn’t need to worry about much battery drain

Okay buddy
