I would like to ask whether the social security card for reporting the loss by SMS is oral or written.

There is a time limit for telephone loss reporting and oral loss reporting. After the time, it will be automatically released, or you can go to the counter to release the phone. As long as the loss is reported, the social security card will be blocked and the password will naturally expire. Take your ID card to the bank where your social security card belongs and reset your password.
