Recently I found a site that provides free sms service to Internet users. Name of the site " mesinsms.com "  . How to use it is very easy. First register yourself at this website. After successfully then login and please enjoy the services provided by this site. Services provided in it is very similar to cell phones that we've got. Everything is free, only capital only an Internet connection. Not bad for the efficient pulse when we send bulk sms to friends. Good luck!
