it is much simpler operationally to have a second phone if you frequently leave and enter the US and care about US agents potentially demanding you unlock your phone upon entry (as i do) almost everyone i know, even the staunchest pro-privacy types, are not willing to go toe to toe with a US customs and border agent over phone unlocking. they just aren't principled enough. i don't blame them. worse, there's no telling what malware goes /in/ to your phone if it gets imaged. yeah yeah, call me a conspiracy nutter, i don't care after what snowden showed us. if one of their machines touches my unlocked phone, i'd consider it compromised. so, naturally, i have a second phone. this offers many benefits: - no potential mission critical disasters if i lose it via robbery, water, or power tripping US border patrol agents e.g. forgot to backup some particular important message or whatever - keybase paper key lets me keep in touch with people i need to, provision new devices if need be, and means i can burn the keybase app upon re-entry into US as it's not something like SMS that they are cognizant of - using whatsapp on foreign SIM gives me some cred as far as not having a purely empty phone, some human interaction, etc. yeah they'd get dragnetted but it's a smaller set of people than my main phone - if it gets imaged by border agents, i can trade it in for a new one at some point in the future or just recycle via apple recycle program. no big deal.
