I have an iPhone5 that AT&T has confirmed is eligible to be unlocked and that process is in the works as I type this. My question is, what cellular carriers in the US can I use the unlocked iPhone5 with and what about carriers outside of the US? Can I use a prepaid carrier's Sim card, if so whose? I plan on keeping this phone for a couple of years and will be doing some traveling internationally as well as domestically.

Any GSM SIM card will work. You can use it with T-Mobile or any of the smaller GSM networks in the US. When you travel outside the US, you can buy prepaid SIM cards in the countries you visit.
