Is the need for an intl SIM card nearing an end?

[Bossman]

I was comparing to roaming sims that charge per certain KB. AT&T has worked well for me in this regards. I usually just do the $30/120 MB. Also, the last 2 times I used it, the price has been prorated, even though the data itself is not. And this is for postpaid, so may not be a good comparison, since we are talking about prepaid.
