At present, China Unicom supports the replacement/replacement of cards in different places, but whether the local business hall supports this business depends on the actual situation of the business hall. If the business hall supports the card replacement/replacement service in different places, the owner must register the user with his real name and bring the original ID card. For the specific business hall distribution, you can log in to the online business hall /sAAG 1 and enjoy a 20% discount on the traffic for half a year!
