Verizon hotspot but Verizon was 1) hard to setup, 2) sucked my data out in a matter of days and 3) is Verizon. I already give Verizon loads of money, I can share the wealth a bit. I went with an AT & T mifi hotspot and data plan and have not had one single problem. I started out the first four weeks of the program on a 6GB plan ($60/month) and found I am barely at 1GB so I dropped it down to 5GB ($50/month) (that's, unfortunately, the lowest plan they offer).
Will be writing soon about those first four weeks. Lot's to say and no time to say it! Whew!!
