1. Customer's reason: the mobile phone is turned off, the memory storage capacity is full, the mobile phone is not in the service area, and it stops due to arrears.

2. Operator's reasons: Except for customer's reasons, the SMS arrival rate of operators is above 99%, which may usually be caused by network failure and other factors.

3. Other external reasons:

(1) Mobile phone firewall application: You may mistakenly put 95566 in the "mobile phone blacklist", which makes it impossible to receive short messages, but you will usually find such short messages in the trash can of your mobile phone.

(2) Trojan horse or other virus software: The principle is similar to that of firewall software, that is, the virus specifically intercepts 95,566 short messages, blocks or fabricates them, so that you can't see the correct short messages.

4. If you use personal online banking or personal mobile banking of Bank of China, please confirm whether the mobile phone number is consistent with the mobile phone number reserved when you register personal online banking or personal mobile banking of Bank of China.
