it seems that travelling with a backup/2nd mobile could be handy, for example:
- if the 1st gets damaged
- some anti-theft apps request a phone number to which they will text the location of the stolen mobile. so the 2nd could be used for that (of course, that would require buying 2 sim cards at destination country).

the 1st mobile would be the more expensive and features-rich one. the 2nd "backup" mobile would be a cheaper, no frills model.

any inputs on this setup?

TIA
