China Unicom will check the communication service, USIM card, user number and usage of iPhone terminals purchased by users every month from the next month when the iPhone contract plans to access the network.

For users who purchase the contract plan of "pre-storing phone bills to send mobile phones", after the iPhone terminal is lost, users can go to their business halls with valid identity documents to handle the business of "reporting the loss of the iPhone terminal". When handling, the acceptance outlets of their own business halls need to print the "iPhone Terminal Loss Reporting Statement", which will be filled in and signed by the users; Acceptance outlets should keep the "iPhone Terminal Loss Report Form" and a copy of the user's ID card for inspection. After reporting the loss of the terminal, you can change the card for the user without comparing the machine and the card. The unpaid phone bill will continue to be paid every month. If the iPhone terminal finds the phone again after reporting the loss, you can take your ID card to your lobby to reply. The terminal will be locked after reporting the loss for 2 months.
