NZtechfreak: Have you disabled the personal data tracking that Apple added back into iOS6 without informing users of it's presence?
The 'Diagnostics & Usage" auto send feature ? If so yes it is disabled.
AndrewMac: If data is barred on the network side, it would just be delayed updating on the web portal side. I saw your data was reset in the first post, do you mean the phone was restored to factory settings? If not, that's worth trying
hamish225: if the phone is off and telecom are trying to charge data, obviously this is a system fault.
freitasm: Don't you have control on Gmail of which mobile devices are currently configured to access your account and the ability to turn this off from the web side?
[Points for Office 365 for having this]
sbiddle: It's interesting you should mention Gmail. On my Android I had my Gmail account configured using an Activesync account and the built in email app because this offers far better functionality over the Gmail app.
Last week I had to disable this after finding my phone was literally flat by 2pm due to excessive data (phone was near constantly showing H+) and battery consumption which I tracked down to the Activesync application. Deleting the Gmail account has solved this. I didn't actually look at my data consumption but it seems that I've possibly had an issue that could be similair
