For those of you have bought our considering to buy Oneplus 12, unfortunately it will not work on the "fastest" 5G network Rogers has. The photos itself will not even display a 5G network option. Called Rogers technician she said she couldn't help. Emailed Oneplus who said to ask Rogers.
Ironically my friend has a Telus 5 G plan and it works like a charm. Telus 5G speed on this phone is 400+Mbps whereas Rogers LTE+ is about 200Mbps.
Guess my only option is either to return the phone or switch to another carrier.
PS: I saw people posting a workaround by downloading an app. I'm not gonna do that since it is a 1000$ phone and the "best" 5G network so I'm expecting more.
Hope anyone else sees this and not making the same mistake I do by wasting your precious time problem-solving sometime that should not be there to start with.
