The answer is that it depends. It depends on who the phone company was that sold the phone and what sim card you are trying to put in. It can get a little complicated because phones are generally locked to the cellular phone company. They also may work, but one might not get 3G for the data stream. You also have to double check the rates since if the phone was not registered as an official phone with AT&T, then they might get you on data charges.
Phones that are unlocked should work with any sim card, though again, one might not get 3G depending on the network. For instance, one will not get 3G with a t-mobile sim in an iphone.
No. The iPhone must be activated before it can be used. You activate iPhone by using iTunes on your computer. You will need a credit card or debit card, access to the Internet and an email address. However, the newer iPhone 3G must be activated either at the store (AT&T store in the US) or at an Apple store.
No You Cannot As Of Yet. I just tried it on an unlocked 3G Iphone 16 gig.
Yes, it will instantly activate. I have used a Runescape Membership Card before and it activated when I put the code in.
The card has no value at all. When the cashier swipes the card's magnetic stripe, the card's serial number is activated. Only then can it be used.
You can use the same SIM card for your iPhone 6 that you used in your iPhone 5.
Well, you have a 2-year service contract with At&t so you better check out that you can change your billing address and emails and name and everything first..
You must find the receipt or else you will be out of luck. There should be a toll free number on the card that you can call and ask them, but the above is probably true; without a receipt they will likely assume that the card was stolen and that's why it is not activated.
Yes.
The original 2G iphone was IMSI locked therefore you could only use one sim with the phone. Newer Iphones 3G and 3GS are usually just carrier locked so you can swap around SIMs including MVNO SIMs that operate thru the same provider. All Iphones from Belgium/Italy or New Zealand are completely unlocked. Some carriers will unlock your IMEI so that when you update the phone on ITunes the phone will be unlocked expect to incur a charge or to be out of contract to get this!AnswerNo. A SIM activated in a non-iPhone will not work in an iPhone.The iPhone must be used with the built-in SIM card that was activated in it initially (or the activated SIM from an identical model iPhone), although that SIM can be moved to another SIM-based phone if necessary.

They can, (unless the card that flipped it says "flip effects are not activated at this time.")
An Apple iPhone 3GS can be purcased unlocked without a SIM card and used with a local carrier's SIM card. Once purchased it is as simple as inserting a SIM card from the carrier of your choice.
