If your phone plan includes mobile to mobile calling it does.
If you're using prepaid it generally won't unless your on the $1 a day mobile to mobile plan.
Yes, provided your ATT phone is SIM unlocked.
yeah
It all depends on what carrier you would want to go with. ATT has good go phones and you can also get minutes to use with the phone when you buy it. Hope this helps.
If you want to use your phone on most GSM providers worldwide, you would need to have the unlock code calculated first using the IMEI # of the phone since unlock codes are unique to every phone.
yes u can I had my att go phone unlocked and tried to use my sim card from st. talk which I found out uses att service towers in my area however, it didn't work. It stated "sim crash"
None. You need to have a either an unlocked phone or an actual Metro PCS phone.
You can't use Verizon service on ATT phones or any other GSM phones. Verizon runs on a different frequency, which ATT phones do not support.
An unlocked phone can accept the SIM card from any cell phone provider. If you have an ATT SIM card, you can use it in an unlocked phone. A locked phone is created by the provider to force the use of its service; an unlocked phone can take any SIM card.
Unlock codes are specific to the phone's IMEI. There are many unlock service providers on the web that will get you your code for a fee. Or you can call ATT (assuming it's an ATT branded phone) and tell them you are traveling abroad and would like to use your phone on a foreign network while away. Usually they will give it to you in that case.

Yes, with a tracfone, the system automatically deducts minutes when you receive or make a call, it also deducts minutes when you text message
No, receiving a call does not cost anything it is the person making the call that pays for it
