You will no longer need to be around your Echo Speaker to make free calls and messages with Alexa. Starting now, you can use Alexa to make calls (including video calls) and send messages from Fire models, iPads and Android tablets. How easy it is to make calls and send messages will largely depend on the device.
From what we know, making calls and sending messages is the easiest on the Fire HD 10 tablet, where you only have to ask Alexa to get in touch; if you have other Alexa-ready Fire tablets, it will require you to tap the home button first. For everyone else, you will have to open the Alexa app to take advantage of these features.
It's worth mentioning that you don't need a tablet or Echo speaker to receive calls, all you need is the Alexa app. Amazon's Drop In feature will also work between tablets and other Echo devices in your home, so you can use your tablet to communicate with someone else inside your house. I guess you can say that Amazon has introduce intercom inside you home, am I right?
