What shortcut key can I press on my mobile phone to quickly check the phone bill?

First enter the address book, click the plus sign in the upper right corner to create a new contact;

Take China Unicom users as an example, enter the number 10010; then click the "+*#" button in the lower left corner , then a "Pause" button will appear;

Click "Pause", and a comma will appear after the phone number. After the comma, continue to enter the number you need to press to check the phone bill. China Unicom users need to press 1 twice, so the number is saved as 10010,1,1, and then click "Finish". Next time you want to check your phone bill, just dial directly from your address book!

Similarly, mobile users and telecom users can save their numbers according to their respective service number operation prompts: Generally speaking, for mobile, it is 10086→1→1, and for telecom, it is 10000→1→1→2. .

One thing to note! A comma here represents a pause of approximately two seconds during the dialing process. Because the prompt tone of blablabla after Guangzhou Mobile 10086 is connected, the number must be saved as 10086,,1,1!
