Dual SIM means that I can use two different SIM with two different phone numbers in the same phone device?

Yes, although you always have to be mindful as to which SIM is active at any given time.

Yes. That's absolutely right. Currently, I utilize two sim cards from two different providers at the same time. Both sims (with their respective numbers) are active at the same time and I have had no problems making or receiving calls from either.

In the Settings Menu you have the option to activate either SIM 1 or SIM 2, the SIM activated will be the SIM (phone number) you'll use until you choose to activate the other one. Even though it can hold 2 SIM cards at once you don't need two, if you have 1 ISM card you can still use this phone.

No It is not a Dual Sim phone, I am not sure about what international version mean, i think it means that it is unlocked from the factory and can be used internationally.

No, you just use the one the one your phone takes (Ex. my ancient Motorola takes a full-sized sim, while say an iPhone 4s uses micro sims). If your phone has dual-sim capability, you pick whichever one you want. Hope that helps.

As you say in your question, only 1 SIM at a time can use UMTS/WCDMA, the other 1 is on GSM or out of luck if there is no GSM 2G fallback. You can choose in settings which SIM is GSM only.

Yes, it is dual SIM. I carry this phone when I head overseas and keep a US SIM in one slot and my WorldSIM in the other. You can set it to go to one SIM by default, or it'll ask you which SIM to use each time you make a call or send a text. I also carry a tablet that lets me send texts, and use Skype when I'm in a WiFi zone. The two devices really work for what I need whether I'm in the US or overseas.

I think you can not have two calls going at the same time, but you can put a call on hold on one sim to answer for a call in the other one. And you keep both sim actives all the time to receive calls

On the menu screen. Go to settings. Choose Dual SIM settings and enable SIM1 only, SIM2 only or both.

I use three different sim cards in my phone depending what country I am in at the time. If you are already with AT&T they can fix you up with a new card with your old number. No problem.

No, I just put in one and it was fine. The home screen displayed the network name for that one, and below that it just said something like "No SIM 2." I believe you could just toggle back and forth between two SIM cards/networks if you needed to based on your travels.

Yes, this phone is a DUAL SIM phone, but different from the others because it uses a MINI SIM card and a MICRO SIM card. This is not a problem, when you get the SIM cards from your carrier just inquire about this sizes, if you currently have 2 SIM cards of the same size, you only have to ask your carrier for the exchange. You can also use only one SIM instead of 2.

Yes it does. Contact seller as there is also a single SIM model. With the dual SIM, you can use it for different networks, personal and work, etc. When making calls you would be asked which SIM to use, and can personalize different ring tones for each. It is also quite user friendly.
