I'm considering buying one and I'd like to do Verizon because of the hotspot capability and the fact that they have LTE in my area. I'd also like to be able to pay month to month and not have data on the device for some months at a time, so I'm concerned that I've read this business about Verizon messing up sim cards or charging activation fees, etc. Can someone clear this up for me definitively without just sending me to a thread? I've read many of them, and the state of things is still not clear to me. I had an iPad 1 with AT&T and it was a cinch to turn the data on and off as I needed to. Thanks!
