cellular

I have a 10.10.2 install running with Clover, everything works (iMessage, FaceTime, iCloud). I can make outgoing cellular calls using FaceTime on my Hack in combination with my iPhone 6, I receive incoming cellular calls in both my iPhone and my iPad, but not on my Hack; it's simply not ringing...

I'm looking for a Wireless Data Card for a CustoMac Mini. Has anyone tried one or have any advice on one? I've found this: http://www.newegg.com/Product/Product.aspx?Item=N82E16833166054 But I don't know what keywords I should be looking for or which will actually be compatible with OSx.
