Firefox OS sounds great, but I don't think that's what this post is really about. It is about OP gaming his/her carrier's promotional gimmick to get free data usage added to his account, 2mbit (mbyte?) at at time. I did something like this once, I wasn't caught, but nonetheless it didn't turn out well. Back in 2005, AT&T would do something like take a dollar off my bill for each dropped call. At the time, I happened to work in a building that had some kind of Faraday cage built into the walls (EMSEC), so I had a reliable mechanism for producing dropped calls on demand. I would just dial the local Time & Temp line on my way to the front door, and then when I stepped inside, the call would drop and I would get the dollar credit. This worked, until it didn't. After about a month, my phone service was terrible and I was unable to place or receive international calls. I ended up talking to tier-III tech support and was informed that the cell tower closest to me was rejecting my device so I was talking to a more distant tower. (I never learned why that prevented international calls.) Apparently the tower had automatically weighed and measured my device and found it lacking! After the tech reconfigured the tower, my cell phone service was good again. I chalked it up to karma and ceased to commit that particular form of fraud.
