Amazon has teamed up with SirusXM to offer all Echo device owners a free 3 month subscription to the satellite radio service. Whether you sign up for the streaming-only plan that normally costs $15.99 per month or the streaming+car plan that costs $20.99, your first three months will be free. This offer is for new subscribers only and your subscription will automatically begin charging you the appropriate fee when your fourth month begins, unless you cancel your subscription before that point. Alexa devices gained streaming access to SirisXM a little over a year ago. With an active subscription, simply say “Alexa, play [station name] on SiriusXM” to begin listening through an Alexa device.
