After settling in Sanya, can the original social security still be used?

In this case, the original social security can still be used.

Moving to Hainan will not affect the local social security, and it is all coordinated by the state. The employee social security paid by the company is registered by the company, which is not directly related to the insured's household registration. The transfer of household registration will not affect the insured's payment in the company.

However, it should be noted that the personal information such as the name, ID number and household registration type of the insured person needs to be informed in time, and the social security agency personnel of the unit will bring relevant materials to the social security agency to handle the change of personal information.
