What are those mobile phone verification codes sold by Taobao?

Now Taobao registration number must use mobile phone number verification code. And a mobile phone number can only receive a few in a specified time. Some users need a lot of trumpet. These trumpets are used to brush credibility and so on. It works for them anyway. In the absence of so many mobile phones, we must find these professionals who sell verification codes to provide them. Of course, the verification code is not limited to Taobao. Other websites are ok.

The machine that accepts the verification code is called "SMS Cat Pool", which was made by my friend. You can earn money by receiving the verification code every day. Very interesting. I hope I can answer your question.
