If no BT it might have an AUX port in which you can plug a male to male 2.5mm audio cable to connect your phone.

I went ahead and upgraded the free Pandora to their $4.99/month Plus plan. I'm using on my iPhone/iPad and connecting that to my Echo and RAV4 via BT. I find that the Alexa app on my devices is a big old pile of cow flop. It is supposed to allow you to see what is currently playing and all that info, but it has a really bad habit of crashing or freezing. However I can open my Pandora app on my iPhone/iPad, connect to the Echo via BT, then I have a stable app the displays what is currently playing and all my radio stations, etc. Whenever I don't feel the need to watch an app to see what is currently playing, then I just tell Alexa to play one of my Pandora radio stations. I like the app though because it allows me to quickly like or dislike songs and to pause and skip without arguing with Alexa. Once I have Pandora trained to my tastes then the app want be so important.
