Answer or not answer strange phone calls?

Of course, you have to answer it. Just because you don't have a strange phone doesn't mean it's not an important phone. So under normal circumstances, I think this kind of strange phone call is still to be answered. Otherwise, you may miss something more important.

First of all, if you are a college student, of course, you often use WeChat or QQ at school. When you make a phone call, you also use traffic to communicate through QQ or WeChat, and some voice and video. You will definitely use less in this respect, but if one day you may not care about yours or WeChat has no traffic, others can only contact you by phone. In this case, your mobile phone may not save his phone number.

If some people need to contact you in other ways, and those who don't have your QQ or WeChat can only contact you by phone, in that case, I don't think you should answer it?
