We get this request all the time to forward text messages from one number to another. There isn't a way to do this in our Verizon Wireless systems, but that doesn't mean that there isn't a way to do it. If the device that is having the messages forwarding FROM is a smartphone, they can download an application from the Market or App Store, or whatever other application marketplace that the device uses. Simply search that catalog for "Forward Text Message," and you will find several applications that will get the job done.
If it is not a smartphone, it will likely not be possible. Thanks for posting. I hope that answers your question.
I couldn't disagree more - convenience is king... besides - will an app forward messages sent to a number if the smart phone forwarding the message is off? I just got a new iphone and I can forward my work phone calls to it but not my text messages? That renders the whole process mute. I will still end up carrying two phones... ug.
