Lost Phone in Vietnam...Any Tips or Similar Experiences?

After nearly 5 years of travel without major issues, it finally happened. I lost my phone in Vietnam yesterday. Not stolen (as far as I know hahaha), just gone. I think it slipped out of my pocket while I was riding a Grab bike in Ho Chi Minh City.

It’s one of those moments that hits hard because literally everything was on there (maps, photos, translation apps, banking access, etc.) Luckily, I had my SIM card backed up to eSIM and was able to get a replacement phone today, but it’s been a stressful 24 hours.

Has this happened to anyone else?
How do you deal with losing such a critical device?
Any hacks for minimizing the chaos if it happens again?

Also curious — do most people carry backups of critical apps or documents in case their phone vanishes mid-trip?
