How much data do you use? I've got maximum 2Gig used in one day, over the past month, on a day I was away from home. Do you ever look or are you on an unlimited plan?
I have an unlimited plan but I rarely use anything as I am always on the WiFi at home and download things to listen to/watch when I'm out and about or travelling
It probably depends on what your connection speed is too. If I had 5G, I'd perhaps use it more. My last speed test was 79MBs, which is similar to landline but varies.
