I appear to have used 200 GB in one month, where I would guess my normal usage to be 5 to 10% of that at the very most.
Internet is delivered through (presumably) a fixed wireless system I don't know what company, but I think it is based in Dunedin. I live in a house (with no phone line) attached to a business, which buys 100 GB per month, of which it uses 30-60 GB for itself, including a 'free internet' for customers. There is a separate feed to my house. Theoretically I can use the remaining 50% or so. I have a separate router and internet logon / password for the house.The Service Provider is able to measure the two separately.
The business has informed me that they had received a monthly account for 260 GB of which they had used 40, and that therefore I was responsible for the rest.
What could I be doing in my situation to be gobbling up such a massive amount of Internet? What would anyone have to do?Could there be another possible reason (eg something to do with the way our Internet is delivered or set up)?
My typical usage is described as well as I can below:
My internet devices are: Macbook Air (every day), smart TV (every day), Apple TV (almost never), 64 GB iPhone (every day), 16 GB iPad (most days, briefly), Android tablet practically never, though a bit recently, and a wireless printer.
I am in the habit of leaving the internet connected for all the relevant devices, and I have been using iCloud to synchronise between the three Apple devices. I have about 300 songs on the iPhone, though none on the Mac (they are on a separate HDD, only connected when backing up). I disabled iCloud backup some time ago. I have never downloaded movies or action games. My iPhone usage is about 1 - 2 hours total each day, not counting phone calls / text messages. If it is relevant (and I don't think it can be) I have used 4 GB of my iCloud quota.
My normal usage is nightly streaming internet radio (7 hours), otherwise a few emails (10 per day max), about 10 minutes of Facebook per day, and perhaps an hour on average of internet browsing. Some of this would involve the occasional YouTube clip. I also download any updates for operating system or apps. I download 2 - 3 apps in a month, usually using them for both iPhone and iPad. In the last month I also downloaded 800 MB of photographs onto my Android tablet, though this was a 'oncer'. Recently I downloaded and installed Garageband onto the Mac, iPad, and iPhone. I don't believe I have, or have had, any other significant use.
I would particularly like it if anyone answering this post could include their own position / experience.
