Hi Michael,

I know it can be done because there are sms services that will send messages for you. You comment to send to all possible carriers and keep track of the messages that bounce back is an interesting thought. Seems like overkill but it just might work.

Thanks.

>>I have a request to allow a user to enter a cell phone number for sending a sms message. I can make it all work except I can't find a way to figure out who the cell phone carrier is so I can complete the address. Anyone know how to do this?
