SiriusXM isn't a global service, and is only available in the United States and Canada. In the U.S., the SiriusXM satellite signal also only covers the 48 contiguous states and surrounding waters, with partial coverage in Puerto Rico. Those living in or travelling to Alaska and Hawaii will not be able to access SiriusXM through the satellite radio signal. However, SiriusXM is available for streaming online across the United States, including areas not covered by the satellite radio signal.
