How to send text messages and set the phone to stop?

It's call forwarding. The mobile phone has this function!

Turn the phone on the mobile phone to another number, either empty or stop!

In this case, if someone calls you, because you have set the call forwarding function, the phone will prompt the empty number or stop! But in fact you didn't stop! This is a kind of no-disturb, others can't get through when they call you, but you can call others or send text messages!
