The 📲 emoji goes beyond just receiving a call to show a dynamic moment of data exchange. It's suitable for replying to a message like "I just sent the file, please check it," or for expressing the situation of receiving an 'order confirmed' notification after an online purchase.

Unlike the 📱 (mobile phone) emoji, this one emphasizes the meaning of 'interaction.' The arrow visually represents the flow of information, giving the feeling of being connected and communicating in real-time in the digital world. That's why it's also cleverly used to confirm, "I got your message."
