Cell Phones & Keeping in Touch

Preparing for Your Move | Getting Settled | Making Osan Home

Use Your Phone from Home

Most modern-day smartphones will work in Korea without any problems. Currently, Samsung, LG and Apple are the most popular among locals, with a continuously growing 5G network available. Most military members simply switch their SIM card and opt for a year-long local cell phone plan for their tour. The major Korean service providers are Korea Telecom (KT), SK Telecom, and LG U+.

Switching SIM cards will change your number and you will not receive calls or texts to your previous number until the SIM cards are swapped back.

Pro Tips

  • Unlock your phone prior to coming: Call your carrier to make sure your phone is “unlocked” before traveling overseas
  • 2-Factor Authentication: Before traveling overseas, it’s recommended to update your accounts’ 2-Factor Authentications to email in case you switch SIM cards and cannot readily access your US number
  • Avoid monthly plans as they do not have a military clause that allows you to cancel your contract for operational reasons
  • Check before buying! Some newly purchased phones may not be able to be “unlocked” for several months after purchase in the States
