Will this plan work for an iphone 5c? And do I need to buy a plan right away?

Okay, so I want to buy an iphone 5c. I'll probably get it right from apple. Will the plan from the link above work with this phone? Second of all, can I use my phone on wi-fi and have no data at all? Is there plan for the same price with unlimited texting and calling and no data, where I can only get internet with wi-fi? Needs to be through At&t. Also, can I get the phone, and not buy a plan right away? If I were to get the phone now, only use itunes on it, and wait until summer to get a phone plan, (when I can afford to pay 25 a month) would that work? I'm trying to not have to buy an ipod and a phone, so if this would work with not getting a plan until summer, that would be great. Thanks!

Added (1). I do know all about wi-fi and where to get it, I was asking if there was a plan which had no data and involved me getting the internet through wi-fi. I have wi-fi in my house, for that matter, and at school.

Added (2). And my friends who don't have data on their phones can get internet at school, and they can also get internet on their ipods at school through wi-fi, so their phones can connect to the internet through wi-fi I think

----------No… ATT does NOT allow iphones on prepaid plans…

Second of all, can I use my phone on wi-fi and have no data at all?
---------- if you do get a postpaid contract plan, you are mandated by Terms of Service to get a cellular data plan… No data = no Smartphone activation… On ATT, Verizon, Sprint, and Tmobile… If you have a Smarpthone, you WILL have a data plan… If you do not like this, the don't get iphone/android/windows/blackberry

Is there plan for the same price with unlimited texting and calling and no data
--------- not for iphone/android/windows/blackberry

where I can only get internet with wi-fi?
--------- wow… You really have slept through the last 15 years… Just wow… Wi-Fi is a signal produced by a wireless router modem via your home internet connection. A router is sold at walmart. Internet is sold to you by phone company. Phone company activates internet and gives your a standard modem. You go to walmart, buy router, hook up router to modem, turn on Wi-Fi… No connect phone to Wi-Fi signal…

Needs to be through At&t. Also, can I get the phone, and not buy a plan right away?
-------- if you wanna pay $600+ FULL PRICE, then sure… No contract no discounts…

If I were to get the phone now, only use itunes on it, and wait until summer to get a phone plan, (when I can afford to pay 25 a month) would that work?
--------- hell no… You want phone now? You pay for it. Get a voice/text/data plan… And pay $90-$120 per month… $25/mo?! LMFAO… Iphones are NOT prepaid!

I'm trying to not have to buy an ipod and a phone, so if this would work with not getting a plan until summer, that would be great. Thanks!
----------well… Looks like your gonna be buying a ipod and a $20 gophone… Lmao… Because what you want, is not possible on this godly plain of existence…
