How does Unicom deal with the number of downtime insurance?

Unicom users can take effect immediately through the following channels: 1 log in to the online business hall/home page, click "business processing" > other businesses > downtime insurance number, and select "downtime insurance number"; 2. after logging into the client of the mobile phone business hall, click service > handling > basic business handling > shutdown number protection/recovery, select "shutdown number protection", click the confirm button, and enter the verification code of the sent SMS. Because some provinces don't support online downtime, if the above methods can't be handled, please call the local hotline 100 10 (with the service password) or move to the local business hall (with the valid certificate), or contact the local customer service for specific handling channels.
