It's the SXM app. I have, however, been searching a few message boards and this is not an isolated problem, and not only on the Rogers network. What I don't get is that 1) it was working recently on 3G and 2) now it only works on Wifi.The Sirius XM app or the Sirius Canada app? Rogers data connection has gotten very spotty. I keep losing my data connection on Rogers in many places in Toronto, never mind anywhere else. It's very annoying.
