For whatever reason, there appears to be a bug in AT&T's system where it is counting certain messages as roaming. I've been able to confirm this with the majority of iPhone users I know here in Chicago. I called AT&T to check on it I've already racked up about $100 in roaming text messages even though I have an unlimited plan and don't know anyone outside of the US. Is this happening with anyone else today? The overages show up when logging into the account, selecting "My Current Usage" and then the "Pay-Per-Use" towards the bottom.
