But it's not just a changed endpoint that can interrupt service. Modified payment information can be an even quicker show-stopper.
I received the below from Sirius Canada.
Were Sirius to have obtained my credit card info from a 'wallet provider' the first time, and subscribed to be notified should the card information subsequently change, I would have been spared the hassle of changing the info myself if I renew.
Note: I thought about obfuscating the ESN above but couldn't see the danger. Was I wrong? Have I just made it possible for CSIS to track my listening habits? (For the record, I listen to the PlayBoy Radio Channel for the interviews).
