Ask HN: what do you use for mobile connection when abroad?

When you are out of your primary country of residence, what do you do for the ubiquitous data link in your pocket?

Are you satisfied just by voice? prepaid card? enable roaming and pay big bucks? or just see who's calling? buy a plan overseas because you go there too frequently? limit yourself to wifi at the hotel?

regardless of the country you usually go to, what do you do?
