Ahhh! Yeah and the MC7700 is specifically designed for use on ATT here in the US. It supports band 17 for sure but NOT band 12.... Remember what I said that if a card supports 12 it'll also support 17 but not the other way around.
MC7700 supports the following bands:
3G HSPA+ (They call it 4G but it's NOT 4G, it's actually 3G or "3.5G" - whatever you wanna call it:
FYI that Videotron is an MVNO (Mobile virtual network operator) which has VERY VERY limited spectrum and mostly piggy backs on Rogers. So as such whatever we're working with with Rogers should apply to Videotron too!

"In 2013, Rogers and Vidéotron struck a 20-year deal, enabling Vidéotron to share its network with Rogers Wireless. This network sharing agreement enabled Vidéotron to deploy LTE on its network in Quebec in 2014, in partnership with Rogers. The agreement also enabled Vidéotron customers to use the Rogers Wireless network as a Vidéotron partner network in order to allow texts to be sent or received, calls to be made and for data to be used across Canada. In 2016, Vidéotron revamped its plans, allowing customers to make unlimited calls, send and receive texts and use data in the United States as well, due to partnerships with US carriers."
