First move somewhere safe, then use a trusted device to contact the place where you last had your phone and secure your accounts. A phone's map location is only a clue: do not confront anyone or enter a private place to retrieve it.
1. Check the most likely operator
Record where and when you last used the phone. Contact the hotel, restaurant, transit operator or airline directly using its official channel. For an item lost at Incheon, use the airport lost-item guide; an aircraft, terminal and airport train may have different contacts.
The Korean police's found-phone service information describes a search and the relevant holding organizations. Its page is in Korean. If the item may be found, ask the office how to prove ownership and whether it has a current record; a similar listing does not establish a match.
2. Secure access from a trusted device
- For an eligible Android device, Google's Find Hub guide describes finding, securing or erasing it remotely. For an eligible iPhone, use Apple's Find My guidance to mark it lost. Availability depends on settings, account access, connectivity and the device.
- Contact your mobile carrier about your line or SIM, and your bank or payment issuer if the phone had payment access. Ask each provider for the safest next step.
- Be cautious with messages claiming to have found the phone. Use official services directly; never give a stranger your passcode or a one-time verification code.
Remote erasure can affect recovery and access to data. Read the manufacturer's current instructions and consider whether you have a backup before choosing it. Do not remove the device from your account merely because someone asks you to.
3. Arrange the rest of your trip
If you need to make a police report, ask a police station or official service what information and identification it needs. Keep any report reference privately. Tell your accommodation or travel companion how to reach you. If you are in immediate danger, call 112 for police or 119 for fire and emergency rescue using an available phone.
