Basically, I wound up buying two iPad mini retinas (one wifi, one 4g unlocked, both 32GB) locally in the last week, so one is going to be sold. I settled on the wifi to keep as I really don't need the cellular capabilities of the other unit (that's what mah phone is for) and the 4g has higher resale value. Anyway, when I bought the 4g unit, the seller was also including his T-mobile SIM card activated with the 200mb of data free deal as he said he didn't plan on buying another cellular tablet and so it would be an added bonus. I tested it and indeed the cellular connection is working. My question to you all: I plan on selling this on eBay, would it be alright to include this activated SIM as part of the package or just remove it and hang onto it/destroy it? Is there a possibility that selling the SIM with it could blow back on me for any reason? Thanks.
