iPad 3G: How much does 250MB get you?
If anything is revolutionary about the iPad, it’s that Apple persuaded AT&T to do away with the standard lengthy contracts for cellular service in exchange for a month-to-month commitment. Equally impressive, Apple also managed to wrangle a cheaper data plan out of AT&T, still sans contract: $15 for 250MB of monthly data. But on the iPad Wi-Fi + 3G, a device with a powerful Web browser, a hot App Store, a YouTube app, and more, how much will 250MB actually get you?
I signed up for the $15 plan over the weekend and used my iPad as I normally would, with the exception of leaving Wi-Fi off to see how far 250MB could really go.
What I used
In a typical day, I use Safari to visit Tumblr, Facebook, and do a few Google searches. One day I shopped for an iPad GelaSkin; another I used the iPad version of Articles to look up two Wikipedia entries. I usually start NewsRack, my RSS reader of choice, two or three times a day to read the latest news over lunch or on the train. I have three accounts in Mail: one is push (MobileMe), the other two pull new messages once every hour. While I get anywhere from 30 to 80 or more messages a day, most aren’t anything more than text, and a good portion are filtered away from my inbox by my Mac. I watched a few YouTube videos, and updated a few small apps—between 5-10MB apiece—and that was generally about it.
There are two options for tracking your bandwidth usage on the iPad. If you tap View Your Account under Settings -> Cellular Data, you can see how much data you’ve used and how much you have left for your billing period. However, I found that this meter doesn’t usually update immediately. You can also view usage under Settings -> General -> Usage, which seems to present a more current picture of your bandwidth situation.
What I learned
When it comes to news feeds, I tested NewsRack with both my custom settings and without. When I turned on some features like downloading images from the latest 10 articles, my first refresh in the morning of my 349 feeds took 15MB. After reinstalling NewsRack to clear out all feeds and use the default settings (with images turned off), an initial download of the 100 most recent articles in each feed took 8MB. Subsequent refreshes to update these feeds later in the day took 5MB with images, and 2MB without.
Toss in a couple of short YouTube videos and small app updates, and I hit the 250MB ceiling in just three days after activating my month-to-month plan.
What happens next
So what happens when the data runs out? Fortunately, AT&T issues two Push Notifications before you hit the end of the information superhighway: the first when you have about 20 percent of your data plan left, and the second at about 10 percent. When I ran out completely, I received a final Push Notification informing me that my plan had ended and offering the options to purchase a new plan or wait until later. If you opt to wait, you are cut off from 3G data until you buy into a new plan. The experience feels much like hitting a virtual brick wall on the Internet, but on the upside, at least AT&T doesn't quietly let you continue gobbling data at an outrageous over-limit fee. I wonder if this new, friendlier data plan billing is part of what Apple means with that "magical" and "revolutionary" bit.
Remember, though, that I never turned on Wi-Fi during this 3G data experiment, so if you’re switching back and forth, your mileage will definitely vary. And that underscores the central point of the 250MB 3G plan—it’s not really aimed at day-to-day use but rather intended for short bursts of very specific data consumption when you’re traveling, out and about, or otherwise nowhere near an available Wi-Fi connection.
Besides aggressively managing when you use 3G versus Wi-Fi, there are other things you can do to optimize those 250MB of data you’re allotted. Two key things to look out for are application updates (AT&T recently increased file download sizes over 3G to 20MB) and Web usage. Since many companies treat the iPad’s browser like a full desktop browser, you’ll get the full, non-optimized version of their Website, which is usually much larger than the scaled-down version the iPhone gets.
But if you use your iPad on Wi-Fi at home, at work, and at the coffee shop where you spend too much on your caffeine fix, the cheaper 250MB plan has a much better chance of making it through the month, especially if you stick mostly to e-mail, general Web and new browsing, and light media streaming. However, if you plan on streaming a lot of video or, say, buying iTunes albums over 3G, you’ll most likely have to pony up for the unlimited plan. I know I will.
