Why should I activate the social security card? My father received a text message.

This situation should be that the mobile phone number left in the bank when handling social security information is the father's.

Now, no matter what personal business you handle, you must reserve your mobile phone number in relevant departments and institutions. So if something happens, you can contact me in time. Moreover, if there is any transaction change, you can also inform me by SMS in time. If I don't have a mobile phone, I will also leave my nearest mobile phone number. But my social security information is sent on my dad's mobile phone. I think I left my father's cell phone number
