Adding date to my Petro Mobility for the first time | Petro Canada Rates and Plans | Consumer forum

I have been using Petro Mobility for a few years and would like to add data for internet access during my upcoming driving trip through the maritimes later this summer. I understand that I need to select the Change Plan Tab when logged into my online account, then select which plan with the Select Plan Tab. After completing this step how do I actually connect to the internet on my Samsung Galaxy A10E phone, are their specific settings that have to been entered on the phone to allow access to the internet when travelling. One last question is will my wife be able to use my phone data from her tablet while in the car with me. Thanks for any info on this.
