I have a family plan which includes Verizon MIFI and a tablet. The MIFi was eating GBs like crazy, so I signed up with ATT Uverse, removed the battery from the MIFI, and bounce all my devices off ATT's Wifi. And as a result I dropped my data to 2 gb monthly. My usage is generally around 1.2 gbs monthly. If I cancel the MIFI and the tablet from my contract will I have to pay two early terminations fees or one?
