One-click dialing should be common to all mobile phones.
Method 1: Press and hold the number keys you need to set in the dialing interface, and function options will appear in a moment. You can set one-click dialing.
Method 2: You should be able to find the settings in the column of call settings set by your mobile phone.
The specific operation steps are as follows:
1. Plug the landline into the telephone line.
2. After plugging in the telephone line, make sure that it can be set when it can be connected.
3. Dial the number to be set directly.
4. After the digital input is completed, press and hold the middle button for more than 3 seconds and make a "drip" sound, indicating that the setting is complete.
