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 literally never have. Same prepaid thing for like 15-20 years. The terms have changed a fair bit over the years but I still only dump the bare minimum for long/no-expiry from the same provider. Averaged out it’s only a few dollars a month.
It has some data now but I still just Wi-Fi hop in the rare situations I need internet.
