Cell Phones & Keeping in Touch
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.
