Hay, that’s such a gut-wrenching story about your grandma’s locket! I totally get why you’re freaking out – losing something with that kind of sentimental value, especially with a WWII photo, is like losing a piece of your heart. I had a similar scare last year when my brother borrowed my dad’s old pocket watch for a wedding, then vanished for days. Turned out he was just camping with no signal, but I was a wreck! I ended up using a phone number tracker to ping his location, and it saved me so much stress. I’d recommend checking out https://geofinder.mobi/ . It’s super easy to use – you just type in the phone number, and it sends a text with a link to the person. If they click it, you get their GPS location on a map, no app install needed. It’s pretty discreet since it doesn’t require sneaking anything onto their phone, which feels less invasive. I liked that it worked globally and didn’t care about the phone model or network. It’s not free, but they’ve got a trial to test it out. It helped me confirm my brother was just off-grid, not AWOL with the watch! Hopefully, it can help you track down your cousin and that locket before it’s too late. Let us know how it goes!
