How long does it take Huawei to change the line after sale?

It is recommended to take the purchase invoice to the local Huawei after-sales service center for inspection and maintenance.

The specific time and price are subject to the final test price of Huawei Customer Service Center.

The address information query method of Huawei Customer Service Center is as follows:

1. You can find the nearest service center through the "Service" page in the member service APP that comes with your mobile phone;

2. There can also be an after-sales outlet inquiry address entrance at the bottom of the official website page of Huawei Mall;

3. Pay attention to the official account of "Huawei Terminal Customer Service" on WeChat, and click "Service Center Inquiry" in "Service Support" to inquire.

Tips: It is recommended to back up the mobile phone data before going to the after-sales outlets, and you can communicate with the outlets in advance to confirm the business hours.

If the service outlets are far away, you can choose the repair service.
