What are the unknown numbers and a lot of SMS verification codes sent by mobile phones? There's nothing I can do to go to the business hall. How to solve it?

Individuals can't solve such problems!

Unless-set the incoming call mode, that is to say, only the phone in the phone book can come in!

However, this setting will be very troublesome!

For example, a friend's mobile phone is broken, or the mobile phone number has changed, and I can't get through if I want to find you!

If it's no trouble, you can come one, join the blacklist and refuse one by one!

In fact, at present, mobile assistants have the function of refusing to harass spam messages or incoming calls, which is generally enough, as long as no one is malicious!

Hee hee!
