Only social security card, can I get insurance without files?

Where did you pay before? If it is in the same area, there is no need for files, and the second unit can simply renew them. If it is cross-regional, because the payment base is uncertain, you need to transfer social security to your account. If there is no file, please go to the personnel department of the company that paid the last fee, or go to the social security center that paid the last fee to handle the social security transfer. After moving to the local area, if you continue to pay it, you will pay it yourself every month, but it is not cost-effective. It's still cost-effective to find a company to pay for you.
