I received a strange message and called but said it was an empty number!

1, the other party doesn't want you to know her or his mobile phone number, and uses the color number function (this is charged, that is, it displays another empty number) or blacklists your number (you can send a text message instead of making a phone call). Now there is no anti-harassment software on the mobile phone, which is really a blank area;

2. It is impossible to make a call when the incoming call is transferred to an empty number, but sending a text message should not display the empty number, so it is impossible to transfer the incoming call;

3. A suggestion: You can also send a text message to ask if you know. Change the card if you don't answer it, so that you can feel at ease. You can try calling 10086 to find out if there is a similar reporting service. No, it may help; You don't have to worry if the other person replies to you in good faith. They just want to get to know you.

4. If it is classified as a system data problem, I suggest you call 10086 and ask her to help you refresh the database of your mobile phone again, because sometimes there are serial numbers or overlapping information, you can try it.
