You have to pay social security for several months before you can use the medical insurance card.

After the payment of medical insurance, the medical insurance will take effect from the month after the insured pays successfully.

Insured persons who are insured as employees and special people who are insured as residents (except newborns) will enjoy basic medical insurance benefits (except personal account benefits) from the next month after receiving the payment. If the insured person or his unit stops paying medical insurance premiums, the insured person will stop enjoying the benefits from the next month after the payment is stopped.
