As they have mentioned to you in another post. At this moment there is no release date for Gigabit LTE speeds on the phones from Rogers. Once they open it up, they will release a memo / list with which phone will support it.
Stay tuned for more information.
Nice that the V30 is getting some update, my LG G7 is still sitting on July security patch in the middle of October. Completely unacceptable and Rogers needs to do something about this. I want this over $1000 piece of garbage replaced by Rogers with a device that actually gets security updates in a timely fashion.
