March 7, 2007 -- SIPphone, a San Diego-based VoIP service, has launched a free Web-based service that allows users to send text messages to mobile phones, the company announced Wednesday.

Gizmo SMS lets users send text messages from any Web browser to any phone in more than 65 countries and on over 215 mobile networks, the company said.

Gizmo SMS automatically locates the correct carrier for mobile numbers used worldwide and prevents computer-automated text spam by requiring users to enter a unique ID before sending each text message, the company said.
