1. Open WeChat and search for electronic health card options.
2. After entering, select the National Health Card option.
3. After entering, select the person to delete, and then select Unbind.
4. According to the prompt, delete the prompt of successful manipulation to complete the unbinding.
If the above methods can't solve the problem, you can contact the health card service provider or relevant institutions, reflect the problem to them and ask for unbinding. You need to provide identification and related information to prove that you are the legal holder of the health card. According to the instructions of the service provider, it may be necessary to fill out some forms or provide some additional information to complete the unbinding process. After the unbinding is completed, it is necessary to check whether the unbinding is successful. You can contact your service provider to confirm that the unbinding has been completed and ensure that your health card is no longer bound to others.
