My wife and I both use fizz, I just found the function of Add a user, what's the benefits of it? We have different mobile plan, how I can maximum the benefits?
You can add a user only (https://fizz.ca/en/faq/how-do-i-add-user-to-plan) only to give him/her the possibility to control your account
The best way to maximize your benefits is participating to the community https://fizz.ca/en/faq/whats-my-rewards-program
It doesn't really help you in any way but giving another person access to your account.
You can only really get more points by being active in the community. That's the best way to do it.
