Unfortunately Rogers nor any North American carrier will carry the 128GB / 6GB model. That model is a dual sim card model and it's a international model as per the sites I have read. So everyone else has the same model Rogers has. Sadly you only have that one option unless u opt to buy that one outright online.
I'd you already have an android phone and you get a P10 plus you can use Google to back up everything. Before switching go into your settings and use Google backup. Then log into same Google account on new phone and everything will sync and move to new phone. Or go to Google play Store and download one of a few different apps that can transfer from one phone to another. I can't remember the name of the one I used but it was called something like one click transfer. It has to be on both phones. It transfers your data by WiFi. Hope this helps.
