Longjiang people's society can activate other people's social security cards on mobile phones.

Yes, provided that this mobile phone number is not bound to other people's social security information.

Since the mobile phone number is the same as that left in the Social Security Bureau, when the registered mobile phone number is inconsistent with the mobile phone number reserved by the Social Security Bureau, the mobile phone authentication will send a short message verification code to the mobile phone number registered by the social security card collection or social security department for identity authentication. In addition, the same mobile phone number and the same message can only be activated once.
