How do voice calls work?

Open a chat and tap the call button. Before the call starts you see how long this call can last, how much time you have left today and what each minute costs, and you can cancel for free. Talk, then pause: what you said is sent after a short pause, or tap anywhere to send it sooner. After 20 seconds of silence the call pauses until you tap. You can switch your mic off, turn subtitles on or off, and turn off the sound of the call. A ring around your AI character’s picture empties as the time runs down, and the call ends by itself when the time for one call or for today runs out. The longest single call depends on your plan. Everything said in the call is saved in the chat. Time is counted while you are connected, and your daily minutes come back at midnight UTC.
