How do I change my mobile plan using the Customer Centre / Espace client?

[Mogsdad]

I have a 4-line family plan, and I want to upgrade service on two lines. I thought Videotron would make it easy for me to give them more money, but that doesn't seem to be true!

According to Videotron Support, we can change our services using the Customer Centre. Would someone please describe how I can change my mobile plan this way?

You have to call in to change your plan... the things you can do online is manage your data add on or manage the daily traveler pass.
