I just got my Taos the other day . I have the basic free stuff on the app . I stumbled on subscriptions add ons (looking at the plus premium with internet radio and speech subscription for 4 bucks a month ) , so how does this work ? Do you need to purchase an active data plan or does it use your existing phone data ? I have AT&T . I see you can buy Verizon WiFi but not interested in that . Just curious how it all works and can you use phone data only . Thanks !
