With my factory AT&T unlocked iPhone. What other carriers can I use. I always thought the phones were able to use with any carrier now. Is this true or is tmobile the only one in the U.S.

How will it work in other countries like Peru (plan on going there soon)?

You can use it on T-Mobile or any other GSM carrier in the US or any other country. Most worldwide carriers are GSM so it will likely work in Peru. It won't work or Verizon or Sprint because they are CDMA. CDMA iPhones have GSM chips, but GSM iPhones only have GSM.
