With my iPad2, I got me a SIM-Card with a volume based plan, but I hardly ever used it because I am almost always near a Wifi-Connection When I changed to the New iPad about a month ago, I reactivated the SIM and used it a bit, but not very much. A few days later I checked the "Cellular Usage" in Settings and was shocked! It showed 168 MB under Sent and a whopping 3,4 GB under Received. The date of the last Reset was the day I inserted the SIM into the New iPad, but in all last year I would not have used this amount of data. All I ever did was check mail when I was out and visiting a couple of Websites, no Downloads, no Videos etc. Today I received the bill from my Carrier. I have 1 GB included in the plan, anything more would have gotten rather expensive. But to my relief, It seems I actually stayed well under the 1 GB limit since I did not have to pay extra. But the question remains, WHY would Cellular Usage show me such a high amount of traffic? It did not change when I was using Wifi rather heavily, so it has to come from somewhere else. Did this happen to anybody before?
