I'm going to iran for 10 days and i want to use my iPhone and i don't know if i should unlock it or what please help

I think you can contact your cellular provider AT&T or Version whatever you have and you can pay a little bit extra and you can get coverage even over seas. My friend did that once when she was going to Europe.

You can contact your service provider. They'll supply you with an international simcard (if applicable) and/or set you up, however, you need to realize that their rates apply! It could be expensive. Most newer handsets such as the iPhone 5 are factory unlocked. If you happen to have a foreign simcard, you could just pop it in and have local service. Another option is to use a Wi-Fi app to make VoIP calls for free. Your best bet is to discuss your international options with your provider.

If you buy an " Irancell " simcard you can use their service and call all over the world.

simcard price is about 5 dollar

you can find international call prices in this page:
