Quark Network Disk cannot receive verification code

It may be that the mobile phone number is blocked by the operator, and you need to contact the operator for resolution. The interception rules are set in the text messages on the mobile phone, so the verification code cannot be received. Go to the SMS blacklist settings, check the "interception mode" and the "black and white list" respectively to see if there are numbers that do not allow text messages to arrive, and then cancel the interception.
