Now add up the cost of every one who’s trying to call you in the country you’re traveling to having to make an international call every time they call you.

And heaven forbid if they don’t have an iPhone. In some countries they’ll be charged large sums of money to text you as well.

I am not sure how true this is anymore, but it was in the US until at least a few years ago (and may still be on many carriers/plans) in many countries they would be charged for receiving texts from you as well.
