I got hit by phantom roaming charges abroad — here’s how to avoid them

You hear horror stories of people unwittingly incurring monstrous mobile bills when roaming abroad.

You tend to feel sorry for these people, while also having lingering thoughts that they’ve been dealt a very tough life lesson.
