What should I do if I can't get the verification code when I log in to Kangkang online phone number?

The mobile phone number cannot receive the verification code SMS for the following reasons:

1. The current status of the mobile phone is turned off or semi-turned off;

2. The mobile phone shields the information of Unicom, and the shielding can be restored;

3. The mobile phone can't receive the short message or set the blocking system short message, which will lead to the inability to receive the verification code;

4. SMS storage capacity is full;

5. The location of the mobile phone has weak or no signal;

If the above reasons cannot be solved, please contact the manual customer service.
