Users can't accept SMS verification code and can't log in to the APP. How to solve the problem of user loss?

In this case, we must first find out whether it is the problem of our own transmission channel or the problem of individual users' mobile phones. If only one or two or a few users report it, it can be understood as a problem with the other party's mobile phone, or a problem with the signal, or a problem with the security settings of the mobile phone. Guide users to solve their own problems on their mobile phones.

If this happens on a large scale, we should consider the sending channel of our own SMS verification code.

There are generally two ways to send SMS verification codes, one is to cooperate directly with the three major operators, and the other is to cooperate with the group information platform company. I wonder which one your company uses? The former has higher investment, and the second method is more suitable for small and medium-sized enterprises or teams. If this is the case, we must consider whether the cooperative platform company we are looking for is safe and reliable, and the SMS verification code cannot be accepted, either the channel attributes provided do not match, or the slow traffic leads to the delay in sending information, and the SMS traffic is detained in the background, which may lead to the low arrival rate and success rate of SMS verification code. At present, many SMS verification code platform companies will provide background status transparency services, so that you can clearly understand the sending status and failure reasons of each SMS verification code. It is suggested to replace the regular and secure SMS platform company.
