You gotta do what works for you. On my main package I've used 433 out of unlimited minutes, 27 out of unlimited texts and 18.2 out of 50GB of data. I've also used only a few dozen gigabytes of the unlimited data in my addons.
You'd probably think I'm absolutely nuts paying for those allowances when I'm nowhere near using them up, most people do, but my mobile covers all of my usage so I don't need a fixed line, which effectively puts my mobile cost for this month at just £6 or less compared to those who have a mobile/fixed line combination.
And I'm getting much faster upload and download speeds then them. And I can use it in 50 countries without restriction.
It's all perception isn't it?
People are happy to buy more than they need from fixed line providers and never complain about their usage coming in way under their limits, but in mobile oh my goodness, lol
Baffles me but each to their own.
