Excuse me, how can I send short messages by phone for free on the Internet?

Actually, there is a software for making free calls. As long as you are an Android phone or an Android tablet, you can install a software called "All Free Calls". There is one in the Android market. After the installation is successful, a customer service sister paper will answer the phone for your consultation. It costs nothing and is very easy to use! As long as there is an internet, you can make a phone call.
