What should I do if I can't use my mobile phone for my health certificate?

Mobile phone number of health certificate? What does this mean? Is it because you can't find contact information when you want to apply for a health certificate? Then you can find Weikang Physical Examination Network. If you forget the mobile phone number reserved when you apply for a health certificate? That's not important. You will get a new card after one year, even if you verify the authenticity, you don't need your mobile phone number.
