Some WP7 Users Reporting Inexplicable 3G Data Usage
Have you noticed anything odd about your 3G data usage when looking over the monthly bill for your Windows Phone 7 device? Some users are reporting mysterious data spikes that seem to be eating up their monthly allotment, and the issue may have something to do with how WP7 devices handle WiFi.
This tale first emerged on Paul Thurrott’s SuperSite, as he responded to some reader questions. One WP7 user reported unusual nightly transmissions of 30-50MB, as well as a huge 400MB burst when taking the phone out of airplane mode. Apparently this wasn’t the first Thurrott had heard of the problem, as he was quick to identify it as a misconfiguration where the phone sends data over 3G, even when it should be using WiFi.
Something doesn’t quite add up here, as the recurring nightly transmissions sound like an app or system service checking for updates or syncing data. Especially if you’ve been downloading lots of apps from the Marketplace, it’s conceivable that one or two get set up in a way that causes them to use more data than you’d expect. What Thurrott talks about seems like another issue entirely, though one that’s just as troubling. In either case, there isn’t any evidence yet as to exactly what’s going on.
Have any WP7 users noticed odd patterns in how your phone uses data? Is your plan reporting that you’ve consumed far more data than you can account for?
