A:AnswerDoes he have internet service? Since he does not have a phone, tablet, or computer, it sounds like he may not.
In that case, an Echo Show (or any smart device) will not work properly.
A:AnswerIf they have a smart phone (Android or Apple) they can download the Alexa app and use it instead of an actual Alexa device. Example - if you had a Show 5 (or 10 or Spot model) and wanted to video chat with someone, all they need is a smart phone and Alexa app and it would work that way, too.
A:AnswerI can not find a way to link Samsung calendar to Alexa. The previous answer was a generic response regarding calendars and not an answer to the Samsung question.
