Be sure to secure your iPhone or Android Smartphone whenever you travel. Precautions will help prevent disaster.

The iPhone or any Android Smartphone is an essential tool when traveling to Korea for  tourists of any country. Google maps, travel guides, language translation, and many other apps are extremely useful. We used them all the time. Using our American AT&T iPhone in Korea was tricky. Most Verizon iPhones from the USA do not work internationally, since they use CDMA technology. Verizon does carry several “World Phones” which work with SIM Cards. We have done the research on our last trip and are sharing the findings with you.

We also have articles on using prepaid SIM cards in other countries:

Here are some tips on using your iPhone in Korea

You can only use foreign SIM cards in an unlocked iPhone or Android Smartphone. A locked smartphone only works on the original cell phone carrier. Most cell phone carriers in the US, including AT&T, allow you to unlock Smartphones after your 2 year contract has been fulfilled. T-Mobile requires 18 months of payments before they will unlock a cell phone under contract. You can alternately purchase an unlocked Smartphone from Amazon, eBay, etc.

If you prefer to unlock your iPhone, you can try jailbreaking it. Jailbreaking and unlocking iPhones are not easy tasks. One slip and you may have bricked your expensive smartphone. You can buy a pre-jailbroken/unlocked used iPhone from eBay or Craigslist. iPhone 4’s typically cost around $150.

This article also applies to using prepaid SIM Cards in the iPhone 5s, 5c, 5, 4s, 4, 3gs, and iPad with 3G or LTE. Android Smartphones utilizing GSM technology are also supported.

Different Smartphones use different sized SIM cards. Most foreign cell phone carriers sell smaller micro-SIM (iPhone 4, 4S, iPad) and nano-SIM (iPhone 5, 5s, 5c, iPad mini) for use in a variety of Smartphones. You should remove the SIM card from your phone before you attempt to purchase a prepaid SIM card in another country.
