Send SMS to mobiles worldwide

GroupMe is the best way to chat with your friends. The application works as a private chat room for your small group. Once you download the application or access the online service, you need to create an account by providing your name, mobile phone number and password, or you can log in via your Facebook or Twitter account. The service then syncs with your contacts and from that moment on, the user can create groups, limited to 500 members. You can add as many as you want and it's always free. It allows you to talk to co-workers, organise game nights and keep in touch with family, all from one place. And the best part is that it works on almost any phone via push notifications or SMS. GroupMe runs on Windows, iOS, Android and the Web, so you can stay in touch on the go.

The other great thing about the application is that you don't need to install the application itself in order to use it. Simply add a contact from your phone book and they can chat with the group immediately. You can chat with your groups directly via SMS.
