Can't connect to FIDO-EXT

Hey guys,

I've just moved up to a remote part of BC (northern Haida Gwaii) for the year. Up until a couple of days ago I was able to connect to Fido-EXT reliably in town, but now I'm stuck on emergency calls only, even in areas where it worked perfectly before. I've tried resetting my phone, my network settings, and even manually selecting the network, but nothing seems to work. I can't even call Fido to ask about what's happening here. I'm worried that I've been cut off for going past 'occasional use,' but the guidelines on that aren't clear. What doesn't make sense to me is that when I was here for 3 months last spring my phone was able to connect reliably the whole time. Am I just hooped here? Will I need to swap to a carrier that regularly services this area?
