We have developed a site, http://Send2World.com.tw, that lets you send text messages between Taiwan, Canada, and USA cheaply.
I had originally developed this system to keep in contact with my girlfriend in Taiwan while I was in the USA. I found that it very useful and saved me a bunch of money so I developed the technology further so everyone can benefit from it.
I would be very interested to see what people think. I have set it up to giving away 20 messages so that you can test it for free. Feel free to email me any suggestions or comment at alchow [at] yahoo.com.
Thanks in advance for your help.
