How much of your unlimited mobile broadband are you actually using?

In one comments thread this week, I’ve had readers say it’s silly to hold out for unlimited mobile broadband when you can save so much every month by opting for a capped plan. In another, I’ve had readers comparing strategies to hang on to their Verizon unlimited accounts for as long as possible.

March data usageMy hunch is that the first group has the wiser strategy. Consider the graph at right, charting my data usage from early March to early April: Even with all of SXSW and more than 900 megabytes’ worth of tethering, I still only racked up 2.13 gigabytes.

And that’s well above average, going by the latest numbers about North American usage from Alcatel-Lucent. That wireless-infrastructure vendor found that LTE users consumed an average of 46 MB a day–about 1.4 gigabytes a month–while 3G users ate up 17 megs a day, or only half a gig.

Am I missing something here? You tell me. Take a look at your own phone’s monthly data consumption and report back in the poll below. To check that detail in Android, open the Settings app and select “Data usage.” In iOS, open the Settings app, tap General, then tap Usage, then “Cellular Usage.” (Note that this isn’t broken down month by month, and that if you want to see which apps ate up the most data you’ll have to spring for a third-party app like DataMan Pro.)

For extra credit: Is that number more or less than you expected, and does it have you rethinking your choice of wireless plan?
