There are people who sign up for a new plan or change their mobile phone number for other reasons. However, if someone else receives and uses the number I used, my personal information may be leaked to that person. Card usage history, bank account numbers, and even home addresses can be disclosed.



First, reporter Kim Min-jung.

Lee Doo-man, who opened a new mobile phone earlier this month and received a new number, was surprised to use the mobile payment system.



The cash receipt card of someone you didn't know was linked to your mobile phone.



[I Duman/Last 2nd number transfer: There was a card that didn't exist here. I did something like this in the first place. It's all straight. Healthcare, A-Land, Innisfree, like this... .]



As it turned out, it was the usage history of the person who used the number earlier, but payment information continues to be uploaded to Lee's mobile phone.



[Lee Duman/Last 2nd number transfer: I called SK Telecom. Can't you block



this

?]

Advertising texts containing real names and notification texts from the town office were poured out, but the news came back that there was nothing the news agency could do.



[Dooman I/Last 2 days number transfer: He says he has to block the reception, or he has to make a call in advance and solve it himself.]



Mr. B is constantly receiving personal information of the person who used the same number before.



[Mr. B/Last August number transfer: I got a text message from the town office, a city gas company called me, and I know exactly how much the person's loan is.]



When I received a text message containing the previous user's home address, I felt uncomfortable. Could not be erased.



[Mr. B/Last August number transfer: I thought what it would have been like if it had been in the hands of bad people (because it was uncomfortable) and I wanted to change it to another number, but maybe my information would go to the next person (I was afraid.)]



Number There was a case of receiving an insurance advertisement text message or a bank account number containing the history of the old owner's illness.
