Spoke Phone Ideas

We are in the real estate industry and as an Agent, I need to be able to send SMS messages to a husband and wife and maybe other parties involved in the transaction. I can do this from my personal mobile using Group MMS, but it fails a lot of the time as some carriers do not deliver the messages.

I would love to be able to send Group SMS messages from Spoke Phone using my Spoke Phone number so I don't have to use my personal mobile.
