Using Drop-in feature, you can send a text message, voice calls on Echo Show like device or a simple call, just like how you do on WhatsApp. This means if you've got Echo setup in your living room and another one in office, you can order Alexa to drop in a message from your living room and broadcast a message. With multi-room music, users can listen to music in any of their rooms or have multiple Echo speakers in the same room for a more engaging experience. You can set the permissions on who gets to drop in on your Echo device. VIZIO 4K Ultra HD display users with an Alexa-enabled device can now conveniently control volume, channel and input settings, as well as turn their VIZIO display on and off using only their voice. Once the group is created, simply say "Alexa, play Despacito everywhere".
Amazon first launched the Echo series in India back in October 2017 but back then the devices were only available on an invite basis.
Shortly after announcing them in the US, Amazon brought its latest Echo and Echo Plus smart speaker lineup to the Indian market in October past year. Another way to set up a profile is using Alexa app on your phone.
