I just bought an Echo Show 8 and only discovered that I can supposedly send SMS text via voice with any Alexa device. But it's not working for me. When I say "Alexa, send text" or "send SMS" it asks "to whom" and I respond with a name in my contacts. After a short pause, it replies, "sorry SMS is not currently supported on this device, but I can send a voice message instead". But that's not for all contacts. For others, I get the response "I can message contacts who have signed up for Alexa messaging".
Reading articles going back two years, apparently this is supposed to work. I can send regular messages, but the recipient must have Alexa installed. But I thought sending an SMS instead would send a regular text to their cell phone, without forcing them to install Alexa.
Amazon.ca support was no help, they just said that the recipient must have Alexa installed. So I'm stumped.
