Hi, I'm planning a trip to US and I currently have the "Unlimited 5G+ Premium unlimited CAN-US-Mexico plan. I want to confirm, if I should keep "Mobile Networks" setting as having my Data on or off? I understand that with this plan, I should not be charged any roaming costs when I make/receive calls, texts, or use my data?

You need to keep your data on as well as turning Data Roaming on too. Your phone will then connect to the nearest compatible US network and you'll use your phone the same way as you do in Canada. You get to do all that and enjoy your vacation, not being charged anything for the roaming.
