So I have a BBRY BOLD, and the basic phone through Verizon and unlimited data plan through Blackberry. Naturally, I never elected the world plan, because I didn't think I needed it. But I now have a friend from Tasmania, and would like to know the best way to send her a text message without incurring additional charges, and without having to add additional services. I have her Tasmanian Mobile number, but not her email, so I cannot email her. Suggestions?
