Can I unlock phone without AT&T SIM card?
I have an AT&T Galaxy SII Skyrocket, with about 3 months left on the contract. According to the AT&T site, I've been eligible for an upgrade for about a month and I want to upgrade to a Note 3. My SII takes a full size SIM card and from what I've seen the Note 3 takes a mini SIM card, so I'll have to get a new SIM card when I upgrade. The problem is that I want to unlock my old SII when I get the Note 3, so that I can use it with a European SIM card when I travel and according to the AT&T site I can't unlock the SII until the end of the year when the contract runs out.
So, if I go out and get a Note 3 today, swap my SIM card for a mini SIM card, and in three months contact AT&T to unlock the SII, will I be able to unlock the old phone when it can't connect to the AT&T network?

The Note 3 however will not be eligible as it will under a new 2 year agreement. However a different route you can choose is AT&T Next if you don't want to be under a contract.
The way it works is you get a device at $0 down initially. No contract. However, you will charged the monthly service charges + monthly installment charge which is about $27 or $32. So it would be your plan + 27 or 32 dollars. The installment charges is basically you paying off the phone in 20 monthly payments, and you can pay it off early if you would like, it depends on you. 🙂

Slight correction, your Galaxy S II uses a mini-SIM card and the Note 3 uses a micro-SIM card. Phones haven't used full-sized SIM cards in so many years that most people don't know what they are.
On to your question. You have to have a non-AT&T SIM card to perform a SIM unlock on the SII. You can use the European SIM card if you have it already or you can find someone that you know that uses T-Mobile or one of its MVNOs and ask to use his/her SIM card to unlock your phone. It would take two minutes or less, then you can give the SIM card back to that person.

The iPhone 3GS used a mini-SIM, so that should work if the S II used the same size SIM card. The VZW SIM card might work, but I think that it is a micro-SIM card so you would need an adapter to put it into your S II.

Yes, I use them all the time. I get mine from Amazon, but if you don't want to wait T-Mobile stores sell them, as well. The T-Mobile price is high compared to what you can get them for online, but it is not a prohibitive cost. One thing to remember, don't store an empty adapter inside of your phone as an empty adapter can damage the SIM card slot.
