If you’re hooked on the convenience of satellite radio, be warned: your bill may see an increase in the coming months. Customer support representatives are now confirming a rate increase for Sirius XM services. There will be a $2 increase for additional subscriptions and a fee of $2.99 for the online Internet radio service (which is currently free with a subscription).
