Have you ever missed an important call during a phone call? If so, you will appreciate the benefits of using a second line. If you receive a call while on a call, you will hear a signal and will be able to answer the call without interrupting the current call.
Instructions
Step 1
You can use two lines during a telephone conversation using the Call Waiting option, which is activated via the phone menu. Most mobile operators have this service free of charge, but just in case, check this point by contacting the subscriber service of your operator.
Step 2
Call waiting is enabled through the phone menu in the call settings, and for most phones it will not differ from the examples below. So, on Nokia phones, you should enter the menu, then select "Options" - "Call" and activate the "Call Waiting" item, and to enable the same option in the iPhone, you need to open "Settings", go to the "Phone" section and enable Call waiting.
Step 3
After the option is enabled, during a telephone conversation you will hear a beep informing you that another subscriber is calling you. By looking at the display, you can activate an incoming call without interrupting the conversation on the current line.
