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?

DisCo Game of Thrones post

3/27/2013: Ethicists Make Lousy Economists, And Other Lessons From the Endless “Game of Thrones” Debate, Disruptive Competition Project

This started life as a draft here a year ago, when I’d gotten fed up by seeing the same old arguments thrown around on Twitter and in blog posts about the HBO series. Then I set it aside, which turned out be a good thing when I had a paying client interested in the topic.

3/29/2013: Social-Media Trend To Watch: Security That Doesn’t Have To Suck, Disruptive Competition Project

With Dropbox, Apple and, soon, Evernote and Twitter following Google’s lead in offering two-step verification as a login option, I’m cautiously optimistic that this competition will yield more usable security than what the efforts of corporate IT have yielded so far. The skeptical comments this post has since gotten have me wondering if I was too optimistic.

3/29/2013: Augmented Reality Doesn’t Need Google Glasses, Discovery News

I revisited a topic I last covered in depth in a 2009 column for the Post. Part of this post recaps how I still use some of the apps I mentioned back then, part suggests some other possible applications, and then I note how Windows Phone 8′s “Lenses” feature could foster “AR” on that platform. I’m not sure all of those parts hold together.

3/31/2013: Q&A: Is T-Mobile’s new math a good deal?, USA Today

The wireless carrier’s no-contract plans may not save you much money if you buy a new smartphone exactly every two years, but if you upgrade less often–or buy an unlocked phone from a third party–they can work well for you. (And if they foster the growth of a carrier-independent market for phones, they would work well for the rest of us.) The post also includes a reminder to watch out for phone-insurance charges on your bill.

Sulia highlights: calculating how much you’d spend on an iPhone 5 and two years of service at the four major wireless carriers; noting the belated arrival of threaded comments on Facebook pages; explaining why Google Maps doesn’t offer real-time arrival estimates for Metro and other transit systems; critiquing the woeful setup experience on a Linksys router.

Where T-Mobile provides 3G service for older iPhones

T-Mobile iPhone 3GT-Mobile announced today that it’s getting the iPhone. But in a practical sense, it’s “had”  that smartphone since it kicked off a network “refarming” effort last year to provide 3G and HSPA+ 4G service on the 1900 MHz frequencies used by the iPhone 5 and older AT&T-specific models, then started marketing itself as a better option for unlocked iPhones. Before today’s news, the carrier said it already had more than two million unlocked iPhones on its network.

T-Mobile’s Web site, however, doesn’t get around to identifying all of these iPhone-friendly markets–an important detail, since without it you’re stuck with slow 2G “EDGE” data service. (6:59 p.m. Engadget reports that new-production iPhones, T-Mobile’s own model included, will support a wider range of frequencies. I’ve revised the title to reflect that.) T-Mobile’s coverage map doesn’t break them out, and a FAQ page only says “Check at your local T-Mobile store for network status in your area.”

(The screen shot above comes from the iPhone of my friend Paul Schreiber, who’s been keeping me updated on where he’s seen 3G service.)

So I asked a company publicist and got this reply:

Weekly output: Android updates, opening Works files, PDF export

Baseball distracted me from work for a good chunk of this week. The good news–by which I mean, the lousy news–is that I won’t have to worry about that again until the spring.

10/13/2012: With Android Phones, The Future’s Still On Hold, Discovery News

I thought that a post inventorying the versions of Android on the current hardware sold by AT&T, Sprint, T-Mobile and Verizon would make for a quick post on a busy week. Wrong: Most of their sites (aside from Sprint’s) require multiple clicks to check that basic detail, and none of them seem to list clearly what phones have downloadable software updates available or promised. Fortunately, the extra work this required seems to have been rewarded with an unusual level of reader interest for a Saturday-morning post, including a long iOS-versus-Android comments thread I’m too tired to read through at the moment.

10/14/2012: It’s time to retire that Microsoft Works file, USA Today

I might not have believed this report of somebody sending out a .wps Microsoft Works document had I not known the recipient who asked about it. I figured that meant there were enough other people who had run into the same problem–or would at least be interested in general advice about how to deal with an odd file attachment–but the lack of reader feedback suggests I could be wrong. The post also suggests one way to get PDF copies of your important files for long-term archiving.
