I’ve been actively using my phone for AIM, but none of my messages has been charged to my prepaid account, so I called Voicestream support to ask about it. The operator’s response: “Prepaid customers aren’t supposed to have AOL access. But I do know they’re conducting some sort of experiment on some of the existing prepaid subscribers. I guess you’re one of the lucky ones.”
So it looks like I can AIM all I want, and I’m not charged for those messages. Yet. (Good thing, too: the BloggerBot is back, so I can post to my mobile blog again. Yay!)
On the downside, I’m charged for making AND receiving calls. Gack.
