As for the social security card, I have been working for a year and have always paid insurance, but the social security card has never been sent to me. The company recently said it would do it.

The medical insurance card (commonly known as social security card) is just a voucher, which can check the balance of your social security payment information, which is equivalent to the bank card we often use, and it is a voucher when used. Even if you don't get a social security card, your account balance will not be affected as long as the company gives you insurance. You can continue to apply in the new company.
