    I have a strange problem that began a few months back.

    Just to give a little background, I only use my Lumia for simple apps - which involves communicating with people via email, Whatsapp, FB Messenger, Skype chats, and basic browsing - and of course, phone calls and text messages. But on the data side of things, nothing more intensive than what I described, and certainly not watching videos or playing games.

    I mostly work from home, and the phone is connected to the Wifi. I go out for a couple of hours each day - shopping/errands, walk, etc. Other than that, there isn't a whole lot of mobile data being used.

    A few months back I noticed that my mobile data (3GB) was getting used up within just a week or so. This was very odd, considering I had not changed anything in that time as far as my usage was concerned. I went to another country for a few months, and on purpose, I subscribed to just 2G services (not 3G) - just to see what happened.

    Even with 2G services, apparently, my phone supposedly used up 2B of data in around 3 days - which was absolutely astounding! And I used exactly the same apps - no change in my usage.

    I'm not sure how this is even possible - given the slow speed of 2G.

    Anyway, I'm wondering what might be the reason and if there is an actual problem with my phone. Is it a virus? I thought Windowsphones don't get viruses.

    I'd appreciate any help with this. Thanks.

    Then I went to another

    Check your Data Sense > Usage. Look for something named Restore Data (or Data to Restore - seems to be regional variations). See if that is where the spike is.

    It's been going around. I've not found any definitive explanations or solutions on it. I saw 2 months peak with usage of data (cellular and WiFi) then it has dropped to virtually nothing.

    I believe it is a server side anomaly causing Microsoft to poll affected users Restore excessively. I can't know anything for sure, just guesses. Staying on WiFi as much as possible seems the only defense. Again, I have seen no cures submitted.

    Thanks so much! That makes sense. I don't have "Restore" on my phone, but I did notice that several things were set to back up - and background data while roaming was enabled too.

    I'm switching my service provider, and I hope that now I'll be able to track my data usage better.

    I'm having the same issue but when looking at data sense I see a lot of "Uninstalled App" usage:
