That's exactly how I travel to tech-related summits around the world, and I have nothing to do with espionage I assure you. I have 3 cellphones - one private (family calls, face time etc), one CDMA phone and one separate GSM for the most of EU countries. And external SSD drive with all my important backups and projects that would take forever to download off of DropBox. And yes - recently even cheap signal detector, as I don't want to be watched in my hotel room, even only for "security reasons" as to whether I will demolish the room or not. (call me paranoid but so was I before Snowden files and I was proven right) I usually carry about $3,000 USD total in different currency - usually 20% AUD, 20% CAD, 30% USD and rest EUR/GBP. Trust me so many times paying with cash comes to be much cheaper, and at some occasions the only way to go! Yes, thumb drive too; usually empty so that if I am at the meeting and someone wants to send me some heavy files, I can give them my thumb and viola! If all this makes me a spy then I definitely need to change my profession :|
