You can buy an iPhone without a plan, but you won't be able to text, call, surf the web, etc. I do not think that was his question , he want to know if he can buy a iPhone without a contract or a phone plan , the answer is yes you can buy one , you can buy it just about anywhere , the thing is you would have to get it activated by the provider , also it would need to be unlocked if not already , this means that it will work for any GSM carrier at&t tmobile etc , since you bought it outright without a plan that co should unlock it for you for free since you done that , most iPhones are locked to at&t from my experience , you have to call them and ask them to unlock your iPhone for another carrier , hope this answers your question
Yes
You cant you got to have a data plan.
yes. eBay.
in order to get an iPhone without a plan the phone needs to be taken to a cell phone store to be unlocked. The iPhone is currently only available for Verizon and AT&T but can be enabled for some prepaid plans. A iPhone without a plan is usually very expensive.
If you have a legal iPhone with ATT service then you already have an unlimited data plan, as the iPhone is not offered without one.
You can buy an iphone without the plan straight from Apple for about 400 USD, if you're not willing to pay that price you can check eBay or Craigslist. You might find a better deal depending on the generation or condition of the iPhone.
No. Verizon requires a data plan for iPhones.
Sprint has the cheapest iPhone plan right now. You can get an iPhone plan from them right now for only $69.99.
You can use the Iphone without a bundled plan but it will end up costing you more. You will have to pay for data by the MB which is always more expensive then getting an amount in a data plan.
Yes, you can use your iPhone 3G(S) to access the Internet if you have an available WiFi connection.
It depends on your carrier. If your carrier is AT&T, it would add a Data Plan to your bill without further notice. According to the AT&T website: "AT&T is Apple's exclusive carrier partner for iPhone in the United States. An eligible data plan for iPhone is required. This data plan covers data usage in the United States and does not cover international data usage and charges. If AT&T determines that you are using an iPhone on your account without an eligible data plan, AT&T reserves the right to add an eligible data plan to your account and bill you the appropriate monthly fee."
You have to pay full price which, i believe, is $500.00
