Can the fast authentication of operator's mobile phone number replace the traditional SMS verification code?

Yes, the traditional SMS verification method has shortcomings, which can make up for the shortcomings of long time and congestion in SMS verification, and can also "check" the local phone number (that is, the mobile phone number quick authentication mentioned by the landlord), which is convenient for users to operate, the experience will be better and the bounce rate will not be too high. However, no method is 100% successful. Even the traditional SMS verification code registration method will encounter unsuccessful situations. At this time, "check" will reissue SMS verification code or voice verification code.
