What is the reason for not receiving the verification code?

1. Error caused by enterprises going to sea: When writing SMS template with verification code, enterprises going to sea may directly put SMS into the template, without paying attention to whether the SMS contains prohibited words and sensitive words, resulting in failure to send SMS successfully. It may also be that the company label used by overseas enterprises' short messages is inconsistent with the company label reported by various countries, which leads to the unsuccessful sending of international verification code short messages. It is also possible that overseas users have obtained the platform verification code too many times, which exceeds the number of times limited by overseas enterprises, resulting in the inability to obtain the SMS verification code.

2. Third-party platform reasons: Part of the reason why SMS verification code cannot be sent is that there is a problem in the channel of the third-party platform, which will also cause offshore enterprises to delay or fail to send verification code messages. If the channel of the third-party platform is not stable enough, when the number of overseas users accessing the platform is too large to support the platform channel, the transmission is likely to fail.

3. Operator's problem: The failure to send SMS verification code may also be related to the operator. There are also some cases where offshore enterprises lose SMS verification code during sending. At this time, offshore enterprises can reissue them. However, the probability of this happening is very low.

4. Reasons for overseas users: The unsuccessful sending of verification code is also related to overseas users. When sending verification code SMS, if the signal of overseas users is not good, overseas users may delay receiving verification code SMS, which may also lead to receiving failure. Or the overseas user's mobile phone is turned off due to arrears, and the interception setting is turned on. None of these reasons can make overseas users successfully receive SMS verification code.
