Jaxtr has announced a free SMS text message service to users worldwide. Jaxtr now supports 38 countries, you can send to any mobile phone whether they are Jaxtr users or not.
You will see a “Send a Free Text Message” box in the sidebar inside Jaxtr, select your recipient country and enter the mobile phone number and send the message. I tested the service it is quite fast i got the message immediately (in France). Along with the message you will get a link to send a reply.
