Using iPhone internationally?

If I travel to a country In Asia for a few days. Can I use my iPhone 5? I have att and its not unlocked. I want to know what my options are. Can I put a sim from some carrier in that country or would I have to buy an international plan? Or is there something else I can do?

Yes, you can unlock it for 15$ within 12 hrs. If you are interessted, send me an email at stefan.zxcvb@live.com

If you unlock your iPhone, you can use it anywhere. I bought an iPhone 5 last week, i was looking for a way to unlock it that i found some websites doing that, prices were so high but i finally found an unlock company doing that for just $25, i ordered the service and they unlocked my iPhone in about 20 hours with my iPhone imei number, no jailbreak, no softwares. It seems they are official apple unlockers doing unlocks through apple.
i'm writing these in mexico with my iPhone 5 in my pocket loaded with a local mexican simcard.

check their website for more info:

  • Will Sprint Unlock My iPhone if I'm Traveling Internationally? I'm going to Philippines with my friend in two months and I was wondering if Sprint would unlock our iPhones. If they will, would it be free? Cause I plan on using it in Philippines. We're just going to buy a sim card. When I was with T-Mobile, they unlocked my phone for China.
  • Why won't my iPhone 4S make or receive calls when traveling internationally? Celluar data is turned off because i don't want to get charged. My phone worked the first week I was in France.

  • Why many Iphone apps aren't available internationally? Why many Iphone apps are not available internationally? I live in Finland and I use of course Finnish Appstore. But I can't download many apps I'd really like to get (Metacritic's, GameSpot's and Eurogamer's Iphone applications for example).It seems that they are only available in US Appstore. Is there any way to get those to Finnish iDevice? There are many more examples, I just named a few.
