Okay here is the deal back in the day Fido was planning on being the company that offered this service in Canada, the first and only. However they did not feel they had the clientele to offer something like this with their finances.
When Rogers stepped in and bought Fido, along with that came this infrastructure for this Portable Internet. Now Rogers has the pocket, and this was actually the main reason Rogers bought Fido as they were no competition for the big 3.
So when Rogers was getting approval by the CRTC to make the deal final, Bell went down to the states and bought the company, the ONLY company, that could provide Rogers with these modems for that type of service.
In the end Rogers and Bell ended up coming to a deal where Bell could use the towers and Rogers could buy the modems. Otherwise Bell was not going to manufacture any modems that would be compatible for the now Rogers system. Yes even huge multi-billion dollar companies can fight like school kids.
This is how Inukshuk was born.
So for "reception" you will not find a difference. I would see who is offering the best deal at the time. Customer service isn't a concern as its Bell and Rogers so expect the worst in the world
However remember it is a "portable internet service" not a "mobile internet service". So you can take it where you want but it will not do hand offs so you could not be moving much. It is a pretty neat service if I could not get Shaw Xtreme I would probably have this product as all you need is a wall plug in to surf.
