You will need a smartphone to use calling and messaging, and voice profiles. The smartphone, if Android, must be a 5 or greater to work. You will not be able to set up calling and messaging or voice profiles without the smartphone. So, if you plan on getting an Echo for your parents or grandparents, thinking this will be a great way to stay connected, you will also have to include the cost of a cell phone and cell phone plan to get this to do what you want. It is not like Skype. You can get a cheap cell phone, but make sure it has the OS required. A tablet will not do for calling and messaging, and setting up voice profiles. The Alexa app will work, but those parts of the app will not. I think Amazon should indicate that a smartphone is needed when purchasing the Echo.
