OTO 무료로밍서비스

When roaming overseas, a carrier's automatic roaming service will cost you 1,000 won per minute just to answer an incoming call.
(If you receive a 20-minute call in the United States, you'll be charged a roaming call for around 90.)

That's why OTO, always thinking about what customers need, launched OTO Free Roaming Service to solve the roaming charge bomb.

OTO Free Roaming Service is a free service that does not cover any reception fee.
Now you can enjoy talking with your family and friends in Korea without worrying about roaming charges.
