Earlier quoted context omitted.
If that happens, aren’t you pretty much walking to the closest mobile phone store? A basic device that’ll give you access to the internet, mail and maps is basically a commodity the same way a toothbrush is.
Problem: with 2FA, lost phone = lost access to your email and rest of digital life, when on a trip (I’ll assume no one travels with their recovery keys).
But, if you use a password manager for Google, not sure if that does you any good. Honestly, regaining access to your various accounts if you need to get a new phone--perhaps especially internationally--may be pretty hard. I do sometimes travel with an older spare phone but it's getting out of support.
