The core point of a cell phone is to make calls. Carriers laugh at the idea of not even including a few minutes per month.
iPhone plans are ridiculously expensive because Apple + carriers know their customers will do anything for their precious exclusive toys so they price them high for the same data at the same speed at the same caps.
I looked and I'm like "oh its only 200 dollars and even that model has about as much space as my old phone, plus all the new better features"
But the fact the plan is twice as expensive is a killer.
As for making calls, if something's important enough I need to make an actual call, I usually use a ground line. Besides, a "few" minutes probably wouldn't add 50$/mo to a plan.
