What should I do if I can't receive the verification code from the mainland in Hong Kong?

If you can't receive the verification code from the mainland in Hong Kong, you can try the following methods:

1. Contact the operator to cancel the blacklist.

2. Try to change the mobile phone number that receives the verification code, and try to use the mobile phone number in Hong Kong or other international mobile phone numbers.

3. You can try to use SMS forwarding service to forward the verification code received by the mainland mobile phone number to the mobile phone number in Hong Kong.

4. If you have relatives, friends or partners in Hong Kong, you can ask them to help you get the verification code and tell you the verification code information.

5. If you often need to receive verification codes from the mainland, you can consider using international SMS receiving platforms, such as Google Voice and MySudo.

If the above methods can't solve the problem, you can contact the service provider who needs to receive the verification code or application for their help.
