Why does an iPhone cost so much on a monthly bill?

My family has Verizon and I really want an iPhone 5, and I need to convince my dad. But when I did research it said $100 monthly. Why is that?

I pay 35 Dollars A month. Just choose a right plan

Your data plan, the fact that its an iphone

So you just think you want unlimited everything for free?

Depends on plan, data should be at minimum 15? A month for like 500mb? But since its an iphone its probably got required data at 35 a month, for like 2gb. Texting would be an extra 10 for only verizon to verizon, 20 a month if you wish to text anyone else, and last of all your monthly access at 10 bucks a month. So at minimum $55 Bones a month (with no extra's) plus it could be more or less depending if your on a family plan or only a 3 phone plan.

If you already have a plan 30 dollars extra
