How to confirm that the other party is really turned off?

The methods to confirm that the other party is really shut down are:

1. The general shutdown answer form is: the number you dialed is currently on a call, or the number you dialed is not answered. There are also three prompts: the phone you are calling has been turned off.

2. You can send text messages. If the actual text message is sent successfully, it means that the phone is not turned off. The shutdown text message will generally be received after the phone is turned on, but the premise is that the text message delivery reminder service will be activated. .

3. You can judge whether the other party is powered off by the response time of the landline phone when making a shutdown call.
