In Portsmouth, NH today. Tested mail to my Tour fine. Sent message out from each of two accounts on my Tour. They went out, but took about 1 minute for them to arrive.
I can't make any calls or send any messages. I got one then poof...nothing.
BIS has nothing to do with phone calls or SMS, only data. It sounds like an issue with your carrier. I cannot see who your carrier is on the mobile forums.
