I just purchased a Nexus 4 to replace an old Android phone. After learning my lesson last time, I've decided to start the phone without a SIM card and sync all my apps etcetera over Wi-Fi so it doesn't chew through massive amounts of cellular data. At this point, the phone is brand new, has never had a SIM card inserted, and I go into
Data Usage. My phone is reporting ~751MB of data usage. I assumed there would be 0 MB data usage, given that I haven't even inserted a SIM. I don't believe the data usage count is syncing from my old phone, as I typically only use a few MB a month, which viewing the data usage on my old handset confirms.
Is there an explanation for why a Nexus 4 that has never had a SIM card in it would report substantial data usage, or is this a bug?
