Why can't the verification code of human organ donation in China be issued?

Prohibited words appeared, third-party verification failed, and operators and mobile phones were blacklisted.

1. When sending the SMS verification code of human organ donation in China, we should pay attention to whether there are prohibited words in the SMS. Check and resend.

2. The reason for the third-party SMS verification code platform is whether there are multiple backup sms channel when the main sms channel is provided. Due to the instability of sms channel, there is no backup channel, which easily leads to the failure of sending short messages and sending them many times.

3. Under normal circumstances, the operator's problem is relatively small, but it is also possible that there are few packet losses during transmission and it can be retransmitted.

4. The user has set a blacklist in the mobile phone security software, and some mobile phone numbers are not allowed to send text messages to themselves. Just cancel the blacklist.
