Offering and advertizing higher data packages, even if you don't use most of it, is a way to justify charging customers more for the plan. I have never personally used that much data either and usually don't even top 30GB in a month. What research Telus does to determine what plans they offer is anyone's guess. Don't be afraid to shop around. You might want to reach out to Customer Care at 611 to check on all of what your options are and to see if there are any loyalty plans they might have available to offer you a better rate and a plan that meets more of your needs.
