Has anyone been able to activate LTE from their iPad? I purchased my iPad from Apple and asked for the Rogers sim, but I haven't been able to activate 4G or even 3G for that matter, from my iPad. I have heard rumors that most Canadian users are having to call in to activate and are still having problems. I spoke to a Rogers rep., and was told to go to a Rogers store! I want to know if this is only a Rogers problem. Has anyone had better luck with the other carriers?
