I searched and didn’t find this offer.
SiriusXM is offering 3 months free of their streaming service. No credit card is required. It says "Cancel Anytime", but I’m not sure why I would have to since they have no real information on me.
This will work on online, the SiriusXM App and with Alexa.
I used a Google phone number and a throw away email and got the deal without any problems. I was able to listen on the app and program Alexa.
