One-card multi-number Hong Kong card can't receive verification code.

1, the Hong Kong card has not opened the mainland package service. Solution: Go to the local mobile hall and get a new calling card.

2. The user's own mobile phone number is blocked by the operator. Solution: You need to contact the operator to solve this problem.

3. Blacklist settings such as SMS security software. Solution: Find the blacklist settings in the mobile phone, and check whether the blocking mode and the black-and-white list have settings to prevent short messages from arriving.
