Ok... so I am thinking about getting a cellular iPad Mini 4 for a couple of reasons. I haven't owned an iPad since the iPad 3 (Spring 2012). So, you could buy AT&T or Verizon at that point. Either version had where you could subscribe to prepaid data plans right from settings whenever you needed it. I know the current iPads have the Apple SIM inside and support for external SIM, and Verizon doesn't support Apple SIM. Do the current iPads support getting a Verizon SIM, putting it into the iPad and activating Verizon data plans only on an "as needed basis?" I currently use T-Mobile for my iPhone 7.... which is fine 90% of the time in the city (Phoenix), but whenever going up to see family in Northeastern Arizona, T-Mobile has no native coverage... and you roam on Cellular One... with is a mix of 3G and Edge (mostly Edge in my experience). Verizon has Arizona blanketed in LTE coverage, so I would like to have an iPad capable of using Verizon LTE on an as needed basis. If I am going up north, I will activate Verizon service for a few gigs and then use Hotspot to give my iPhone a connection as well.
