I feel like every two years I need to call my carrier and complain if I want a decent deal. They will do things like upgrade my plan on their website to have 10 extra gigabytes of data but won’t upgrade me to it until I contact them. There’s also all the new member exclusive deals that I feel make it impractical to just sit on one plan for an extended period of time.
I think I’ve been on the same plan for about 10 years now. I’m with one of the only non-evil carriers in Canada, and I’ve never really felt like I needed more or wasn’t getting my money’s worth with them.
