I currently have the $15.00 a month prepaid base plan. My next auto top up is around 8-10 days from now. I'm thinking of switching to the $50.00 a month unlimited Canada wide base plan. So I would need to switch it the day before auto top up takes place? Also I do have some voice boosters left (approximately 350 minutes). I know they don't expire but how does it work when I switch to the 50 dollar unlimited Canada wide? Do the minutes just stay in my account ? Only get used If I were I switch back to a base plan that requires voice boosters? And are you allowed to switch between base plans as often as you wish. Not that I will but wondering if there are any regulations with that. Thanks!
