How to set up a mobile phone? I can't get a call from Hong Kong.

Smart phones have a number segment screening function, which can screen all calls and text messages in a specified number segment. Here, a Huawei EMI9.1system mobile phone (the screen methods of other brands are similar, please refer to the following operation methods) is used to demonstrate the operation process:

First, turn on the phone, find the "Dial" icon, and click Open.

2. After entering the dialing interface, click "Three Points"-"Harassment Interception" in the upper right corner.

3. Click "Interception Rules" in the lower right corner of the harassment interception interface.

Fourth, find the "blacklist" option and click Open.

5. Click "+"at the bottom of the interface, and then click "First Number Match" in the pop-up options.

6. After opening the initial number matching, enter the number segment to be blocked, and click OK (if you want to block all Hong Kong phones, just enter the area code "00852"; If you want to block a call in Hong Kong, if the other party's call starts with 0085211,enter 0088.

7. As shown below, after adding a number field at the beginning for matching, the number field will be added to the blacklist, followed by a "*", which means that as long as a number is specified at the beginning, it will be completely blocked.
