Hello, i bought an Alexa and downloaded the latest app off the play store onto my samsung galaxy phone. I want to be able to send sms messages. I have followed the instructions i have found on the internet to enable sms, but on my screen there is no sms option button? All i have is my mobile number, then underneath is permissions, which says allow drop in, which is on, there is no caller id or sms option as is shown on the tutorial. What am i missing?
