In the computer world, doing a ping means verifying the connection status between a local host and a remote computer. In other words, it can help us to know whether a specific connection is accessible or not (it can help us to find out whether a web is down or even if our Internet connection isn't working).
Make sure your messaging service is working correctly
SMS Ping is an application that can help us to find out whether a user is receiving our messages, therefore, we can get to know if the service isn't working correctly or if the problem has to do with our connection if we carry out the verification on several numbers.
The application can send messages to the contacts on our list who won't receive any notification about the SMS received. Neither will they be delivered as standard text messages. As we said before, it's basically a method to check the correct usage of the service without any other intention, therefore, it doesn't show any evidence on the receiver's phone.
