|Have you tried sending them to your email account? Instead of a phone number, in the "send to" field put your email address and see what happens when you hit "send".|
I know I can send a text message to a cell phone from my email so the reverse should also be possible. Try it and see what happens and report back.
If that doesn't work, try contacting your cell provider's support people and ask them the same question. I'm sure there has to be a way.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
