Hello, I have China Unicom’s air network connection, but I cannot receive the SMS verification code and cannot pay.

If the verification code cannot be received, it is recommended to change to another mobile phone for testing. If it can be received, it may be a problem with the mobile phone. If it still cannot be received, it is recommended to contact China Unicom customer service for more help. The website for China Unicom's air access is www.10010.com/kzrw. You can directly visit China Unicom's online business hall for air access services and select numbers and packages to access the network.
