I lived for months with a 4GB roaming plan. Given, I was not using it at home since I had a wifi connection, but I rarely came close to using all my data unless I was watching YT videos when traveling or something.

I share your sentiment and I agree we should be more mindful of people with metered/slow connections, but the last statement feels blown out of proportion.

I've had a 1GB/mo $5/mo plan from good2go for the last 2 years. I've never gone over it. But that's because I go from wifi to wifi all the time and I'm very careful when I'm on cell. That definitely doesn't work for most people!

I had a 200MB data plan until ~ 2018.

I had data turned off most of the time. At home and in the office I had WiFi. Loaded the map before I left home.

Most other places I was too busy doing whatever I was doing to use a phone. Since upgrading, I guess I can look products up in stores now. That's about it.

Not using it at home likely discounts a lot of personal consumption. If you can get your fill at nights, less need to access the internet during the day.
