How to view the usage history of Huawei P40Pro

You can log in to the online business hall or the handheld business hall with the mobile phone service password - **Traffic usage, and you can query the traffic usage. For more service discounts, users can pay attention to "Anhui Telecom" WeChat***.

The methods for inquiring about the Internet traffic and phone charges of telecom users are as follows:

1.Dial 10000 directly and enter the corresponding ** according to the voice prompts to complete the inquiry.

2.Log in to the online business hall of China Telecom through the mobile phone number and service password, and click Query under the inquiry service menu.

3.Log in to the mobile phone business hall through the mobile phone number and service password, and click Query under the inquiry service menu.

Dialing** does not produce a call log, or the call log is lost. Take the following steps to troubleshoot:

It is recommended that you click Dial or **, and click All Calls on the Call History List page to display all call logs. Selecting other options, such as missed calls, may cause only a portion of the call to appear.

It may be that you have set up to merge call logs by contact, which causes the call logs of the same number to be merged. It is recommended that you click: Dial > Settings > Call History Merge > By Time to display all call logs.

If the same contacts are saved in the main space and the private space, the call history is displayed only in the private space. It is recommended that you view the call history in the private space or migrate the contacts to the main space: Go to the private space, touch Settings > Security & Privacy > Private Space > File Migration > Private Space to the Main Space > Contacts, and the call logs will also be transferred to the main space after the migration.

The system sets the upper limit of 2,000 call logs to be saved, and when the call records reach the upper limit, the system will actively delete the old call records by default and keep the latest 2,000 records. We recommend that you clean up your useless call logs in a timely manner or back up your old call logs: Open Backup, select a backup method, and follow the on-screen prompts to complete the backup.

If the above solution still does not solve your problem, it is recommended that you go to the business hall to print the detailed list for inquiry.
