I don't know if I'd say that's a good solution. If travelling for pleasure, that would mean wiping my personal data from my device - contacts, messages, emails. It would also mean logging out of all network services. Or just leaving that data at home. Being able to stay in touch while away, and retain access to my online accounts is really useful. If travelling for business (even to a country with poor broadband access) I may still need access to vital business data. I can't always leave this at home. Sure, I could VPN home but if I am to travel with no private data at all then that would preclude the possibility of using certificate based encryption and relying on less secure (and memorisable) passwords. Travelling without data is very difficult today, unless you plan on being completely disconnected.
