Hack the other party's number and send a message to the other party. Can he receive it?

After the other party's number is blacklisted, it does not affect the user to call or send a message to the blacked-out number, and the message to the other party can be received normally.

But if the other party blacklists your number, you can't call the other party or send a text message, and you are directly rejected.

Extended data:

The function of mobile phone blacklist: it is to prevent yourself from being harassed and intercept harassing text messages and phone calls.

1, it is not a real blacklist, it is only stored on your mobile phone, not on the mobile server.

When a user calls you, if he is on your blacklist, your mobile phone will send you a short message saying that your mobile phone is busy or other information.

3. It's not that a blacklisted user calls you, and the mobile phone will prompt him for information. Mobile doesn't know that you don't want to answer the user's phone, but it will call you as usual. Your mobile phone lied to China Mobile, giving the other party a disguised message that the line was busy or nobody answered.

When there is a message, as long as you have a signal, the mobile phone will send it to you. You can't see it yourself, but it has been sent to your mobile phone. You can't see it. It's just that the phone is blocked and I lied to myself.
