How to delete my previous phone records and SMS records? Online business outlets can't be found.

Taking the customers of Henan Mobile as an example, the customized broken order service can be handled in the business hall (no business function fee), and it will take effect immediately after the customized broken order. The list cannot be queried from the effective date, but the list before the effective date can still be queried. Customizing this service will limit the query of all call lists (including call lists, SMS lists, GPRS lists, Monternet lists, etc.). ) during the subscription time. If the business is cancelled on the same day, it will take effect in the next month, that is, the list can be queried normally in the next month, and the crushed list will not be restored. In view of the different business regulations in different provinces, you can call local 10086 to get more help manually.
