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 have a prepaid plan that I never change. It costs nothing per month and I get 10 MB inclusive. I only add internet volume bundles when I need it for navigation for longer trips - to ensure it does not exceed that price (gets slower after).
