Same issue with my iPad mini... it is an LTE version, but the service has been switched off. It started happening after I popped it out and pushed it back in.
I got another recent problem I just discovered which I was not sure about before. I had a sim card from Smartone in Hong Kong of which I used in my iPad mini for Data connection. Before departing Hong Kong to China I switched of cellular service on my iPad. A few couple of days later I used the iPad via wifi for days 2 until 4. I get back to Hong Kong and found a huge bill for roaming 
of which gave me a negative balance on my sim card. I was almost positive it was off the whole time as well as I had personally switched it off. This time I left hong Kong and headed over to Thailand and was going to make sure that this did not happen again and switched everything off again. I get to the Hotel and found that I had a local Data connection on DTAC and that I was roaming with roaming data charges used. I was really pissed and took out the SIM card out of the tray.
Conclusion: Either Smartone SIM cards are sneaky and turn themselves on while abroad or there is a bug in the OS which turns the SIM card Cellular service on by its self.

Oof. That's bad. You had Data Roaming turned off as well? If that's the case, i think it is definitely something you need to take to your carrier and/or Apple. Neither will likely claim any responsibility TBH but at least it's on the record and maybe they can look into it. Very very weird that it would transmit cellular data even in airplane mode.
Data Roaming was turned off as well. Not sure exactly how but it seems to turn its self on. Whether it is a sneaky move on behalf of the carrier or some sort of bug in IOS 8 is something I am not sure of. What I am sure of now is that there is a problem but I am not sure whom is to blame yet. At first I thought that maybe it was my fault (although I had doubted it), but I am sure now that there is a problem with one of the two when using Smartone SIM card from Hong Kong and then going into China with everything switched off.
Last possible possibility is the government in China hacking into it and turning it on. We had hacks out of China before from their government so this would not surprise me. I was a victim to that last iCloud log in hack by the Chinese Government where a pop up popped up on the screen asking you to log onto Apple to be able to continue.
