I have been using my BlackBerry Z10 for the last two years while living in Canada, after my most recent trip to the US I returned home and found that it no longer connected to Verizon's "extended network" and I have no LTE coverage. This leaves my phone connecting to Rodgers network which has terrible coverage in my area. I am wondering if this would be a problem with my phone or if something in Verizon's roaming network has changed.
