Verify phone and voip

hi! I can’t verify my phone number, your system write me this message: “Phone must be mobile not voip” I was write my phone number, active sim card! What wrong? Why i can’t do this? I registered to buy and sell goods, but I have been waiting about a week. I wrote a friend’s number, friend of a friend, but still wrote this malicious inscription. In my personal number, your system reacts the same way, ask you to understand this issue!
