10086 how to check whether someone else's mobile phone number is down?

Two methods of whether the mobile phone number is down:

One: Internet inquiry

Nowadays, many people check whether the mobile phone number is down, logged off and online. Through the internet, I like to look at it quickly. Just open WeChat, search: Daji Quick Check, and fill in the mobile phone number, you can know whether the mobile phone number is down, logged off, online, etc., which is very convenient and saves time.

Second: dial the number.

Making a phone call is not an ideal way. If the other party has set up call forwarding and the call is forwarded to a stopped number, you will hear that the other party's telephone system will still prompt "The number you dialed is stopped" but the other party has not stopped at this time.
