Can a sender just send a message to my Google Voice (GV) number and it goes to me? Or do I have to send them an SMS from GV first to initiate the conversation?
The reason I ask is that once I had setup my number I tried to get my wife to send a text message to my GV number and it wouldn't allow her to, I sent her a message, and after a very long waiting period she received it, but after that she could send messages to my account. I haven't had a chance to get a friend to text me to find out yet so I thought I'd add the question to SU for conversation and posterity sake.
My hypothesis:
It had been too soon from when I setup my GV number and they hadn't initiated the SMS service on that account yet.
