I do not have much data allowance on my smartphone as I have an i pad and a PC which I use all day long, however I do connect to the Internet on the phone at least once a day to delete all the emails that also come to my phone.
As far as general browsing etc, I occasionally will send a message on Messenger if my phone is handy and my i pad is not, will also check SMS on phone only, and occasionally just browse particularly if I am at work or out, or just check emails.
So although I thought my answer would be NO, it appears i would connect to the net at least twice in a day, and probably more.
Yes, and more often than I would like. I like it's usefulness when I am out and away from my computer to look things up, but I find myself using it too much for entertainment purposes. I really need to work on that!
Ever since I had to stop working,I decided that I have no need for a mobile phone of any kind.Having said this, my neighbour bought me a basic Talk & text one for emergencies when I am out,after I had a very nasty fall which put me in hospital for almost a week. I never use it though!!! I have my laptop which does everything (and lots more than!!) I need for internet use. I am more than content with this.
