On days I'm at work, 30-50MB/day, when I'm not, usually quite a lot less as I will be using wifi most of the time. I occasionally tether, and when I do, obviously I use a lot more but normally about 800MB/month on DC-HSDPA/3.5G connection. This may increase a lot now I have started listening to streaming radio in the car though! Unlimited data tariff (including tethering), LTE coming next month.
When i had unlimited data, I abused the service and now that I am on a 2gb plan, I am extremely conservative with my data
I miss downloading torrents and streaming movies on my phone
I never felt the need for 4g. My 3g connection at 3-4 Mbps download allows me to watch movies (mostly youtube historical documentaries) and listen to tunein all day.
I do not use wifi even at home, too lazy to switch, i have 5 gb at big speed then going down (people say it does not happen though), but i never finished the 5 gb on the phone sim (i have 5 more gb on a stick sim that i can put in my dual sim phone if needed) just once or twice got close to 4.5 or so.
IMO 4g is only for replacing the landline in tethering, but i like my 1-2 ms latency on the landline, 1gbps best effort at 15 $ so far didnt think 4g could replace it, really.

I use around 100GB a month on 3G
Tunein Radio is pretty awesome!

EDIT- i fail at markdown
Wow. I average around 200 MB a month.
Typically around 1.5Gigs. In the summer I'll run much higher...generally over 10Gigs but most of that is due to tethering.
Around 60-70GB a Month maybe more sometimes.
I use around 30GB on lte with att unlimited grandfathered plan.
about 1-2 gb's on 3g.
Really wish I had unlimited 4g, I fell limited. Never watch video on it just browsing.

Anywhere from 1 gig to 100gb. average is usually 30ish.
I use about 5GB per month in 3.5G (HSPA+).
Yeah. I travel a lot, so need Internet for my business.
I use about 500M in 2G- -

Where in the hell are you getting 4G? I didn't know they actually had standards compliant 4G available yet.
Oh, for the record, I've used a total of 640 KBytes of mobile bandwidth last month. Should be enough for everyone.
600 megs 3G vodafone India
United Kingdom via EE.
Yes. LTE is not 4G but more 3.9G. But people get confused. There is only 2 that i am aware of. that's SK telecom & Everything Everywhere (trial)
3-5GB per month normally, mainly icloud (music).
My provider just updated the data usage, went over 1GB within 13 days
About 1GB per month on 4G (where available). Mostly use it for Web browsing as all my music is downloaded over Wifi with Spotify.
I only use about 500 mb now days, because I only use to read rss using feedly when on the way to office
I have used more than 100Mb / day.
Maybe 3Gb/month.
Some days I use a bit less than 100Mb in other more.
