Is the missed call reminder a scam message?

Hello, this kind of situation is quite common. Sometimes I can't hear the bell, but I see a reminder of missed calls. When you think it may be someone you know, returning the call will become an empty number. There are many such calls, most of which are harassing calls. They are dialed through the Internet platform and belong to virtual phone. And the number will automatically jump every time, not a fixed phone number, so when you dial again, you will generally be prompted that the number you dialed does not exist. Try not to answer strange phone numbers, especially off-site calls, so as not to be deceived.
