Do you have an unlimited data plan where you can stream the radio?

If not, you can try downloading songs instead. Also, I believe you can record the radio with TuneIn radio. So, if you must, you can record it when you're connected to WiFi, and then play it when you're away from WiFi.

the s4 does not have an FM radio. However, streaming apps do not use FM frequencies to get radio, they use data.

I was looking for the fm radio on my SIII American version and discovered there is none. The UK version does however. Does the US s4 have fm radio. The streaming radio apps are worthless when you are out for a walk.
