How much would it cost to switch to an iPhone?

I have a basic phone in sprint and I want either an iphone 4, iPhone 4s, or iphone 5. How much would the cheapest plan for TWO iPhones (both same model) cost? How much would I have to pay monthly if i choose the cheapest plan?

EX: Cheapest for iphone 5 is 500
for iphone 4 400
iphone 4s 450

The cheapest two line plan on Sprint that allows the iPhone (or any other smartphone) is $150 a month, before taxes and other fees, and does not include the $36 per line activation/upgrade fee.

The plan is the same regardless of what model iPhone you get. The only difference is how much the phone will cost you up front. Keep in mind that taxes and other fees (such as E911 and the USF fee) add on between 10%-30% to the final bill, so the final bill will nominally be between $165 and $195 a month, there are employer discounts that can reduce your bill through Sprint, however you would have to check with your employer for details on that (human resources department).

  • Would I be able to switch carriers without having to switch phones? I'm with Consumer Cellular and I have an iPhone SE, but I'm thinking of switching carriers so that I can get unlimited data. I don't want to get a new phone because I've had my current one about six months, I really like it, and it works great. I'm not locked into a contract with Consumer Cellular. Would I be able to switch to another carrier without having to purchase a new phone?
  • If i switch to Verizon and get a IPhone how much will it cost monthly? Well my mom wants to switch and I think its cheaper for new comers, and I want to pay for the phone for myself and help with the monthly pay as well and i'm not old enough to get a job so I need ideas please: o)
  • How much would the iPhone 5 cost if I upgraded from iPhone 4? I would like to know how much the difference would be for the iPhone 5 if I upgraded from iPhone 4 (not 4S). I know there's a charge but I would like to know how much (British £) thank you.
  • How much would it cost to switch iphones under a two year contract? I have an iphone 4 and its pretty much destroyed. I cracked the entire back and the front screen. I want to upgrade to the iPhone 5s but i'm not eligable for an upgrade yet. Could I still switch phones? And how much would it cost? And what is the full retail price of the iPhone 5s?
