Signal messengar app is (mandatory) installed on the phone. But I can add another device to access Signal. For example a PC. If I type a message on my PC, which route does the message take to be transmitted to the receiver? Does it go via my LAN to the phone and is transmitted from there: Obviously it is available on my phone. I suppose the message itself takes the same route. But can anyone tell and explain? Same with WhatsApp? #signal #whatsapp
