I'm from Changchun, and I want to buy a Unicom nickname, Guangdong 3.9, recently, but the seller told me that it's okay to transfer the card without losing it. Who knows?

He's right, the transfer is in real-name registration system, and your card is your name. If you don't want to use it in the future, you must go to the business hall to cancel it, otherwise you will be fined. If you don't transfer the card, no one can find you. However, if you don't look at the house, many businesses will not be allowed.

You can transfer money in the business hall with your ID card, free of charge. But you can't close your account for three months ~ it depends on your own needs.

Did I make myself clear?
