Assuming the phones are of the same specification for the SIM card - yes.
Unlocked GSM cell phones should work with any provider. You will be able to tell one the sim card is put in the phone.
You can put any SIM card in an unlocked cell phone.
all you have to do is put an activated sim card in the phone it you should have no problem using your new phone :)
You can - provided either the new phone is unlocked (not tied to a specific network) or both phones are on the same network.
Unlocked phones are phones that you can buy that are not permanently connected to any phone company. You can get a cell phone plan from any company that you desire after you own the hardware. If you are going to be traveling, it is a good idea to get unlocked phones. This will allow you to put them on a plan with the main provider in the country that you end up in, which may be different than the main provider at home.
If the phone is unlocked you should be able to put any type of sim card in there as long as it is a GSM phone with a sim card slot.
Sim Card SwitcharooMost phones that accept a SIM card can be unlocked and used for any service that uses SIM card technology. AT&T and Tmobile phones & SIM cards can be used in this way. However Tracfone and Net10 phones and SIM cards cannot. For AT&T and Tmobile, Prepaid or Contract makes no difference. I use my ATT / Cingular contract service SIM in a T-Mobile Prepaid phone. (unlocked of course). The unlocking bit, depending on the company that makes the phone, can get a little tricky; but if you put some time into searching, you can find the information you need for a small cost or most likely free altogether. I am leaving out info pertaining to technology compatibility as most state and abroad phones are GSM, and you most likely have a GSM SIM card.
Yes, An "Unlocked" Phone means you can put ANY operator ("Orange", "Vodafone" etc) SIM card in it.
all you have to is put your sim card into it and wait a few seconds and it will read your sim card.
Metro PCs is able to "flash" phones from other carriers for use with their service under certain conditions. The phones must be CDMA, meaning they do not use a SIM Card (Major CDMA carriers include Sprint, Verizon, Qwest, Cricket, Alltel). You will not be able to access all features of the service when using a flashed phone, these phones are good for calls and texting only. The phone does not be unlocked to be flashed.

Yes, provided your ATT phone is SIM unlocked.
