How to use a VPN for overseas travel: 5-step guide from before leaving the country to returning home

Step 1. 1-2 weeks before departure: How do I install and test connect?

The goal for this step is to install StageVPN on each device you plan to take with you a week or two before leaving the country, and try connecting to it once on your home Wi-Fi. Local data may be expensive or slow, and it may be difficult to receive an account verification text. If you complete the installation, login, and permission screens that appear when connecting for the first time in Korea, all you have to do is press the connect button locally.

1. Install the StageVPN app on your smartphone and StageVPN for Chrome on your laptop's Chrome browser. Install from official sources, such as the App Store for iPhone and Google Play for Android. We do not install installation files or configuration profiles from unknown sources.
2. Log in and check your access location. The default location is South Korea. You can choose a country in the app or use automatic selection.
3. Press the Connect button. iOS will ask you to add a VPN configuration, and Android will ask you to allow the VPN connection request. Verify that the requested app is StageVPN and allow it.
4. After checking the connected sign, try opening a website. When it opens, the test connection is complete. Also check that the permission screen does not appear again when you disconnect and reconnect.
5. Check the VPN regulations of the country you are visiting. Ministry of Foreign Affairs Safe Travel OverseasPlease check with the local embassy information. Some countries restrict the use of non-government approved VPNs (as of September 2026).
6. Choose a rate plan that suits your travel period. It costs 8,000 won per month and 50,000 won per year, and both are auto-renewable subscriptions. Even if you cancel, you can use it until the end of the payment period.

In a test connection, try connecting automatically to Korea once. When using domestic services while traveling, choose Korea, and when the only goal is to protect public Wi-Fi, choose a nearby location. If you check in Korea whether both methods are working properly, you will not be at a loss while on the spot. If your family or group travels together, they will each take the same test on their own devices.

Step 2. The day before departure: What updates and accounts are checked?

The day before departure, check anything that may be difficult to change during the trip. These include operating system updates, subscription status, payment method, 2-step verification method, and banking settings. Local update capacity is a burden, and account recovery is blocked if you do not receive a verification text.

1. Update your operating system and StageVPN app to the latest version. Save data by installing on your home Wi-Fi.
2. Check your subscription status where you paid. Make sure your payment method expires during your trip.
3. Check the two-step authentication method for your StageVPN account and your email/messenger account. Have an authenticator app or recovery code handy as you may not be able to receive texts overseas.
4. Make sure the Foreign IP Blocking service is turned on in the security menu of your banking app. If cancellation is necessary, it will be processed according to the bank's instructions. Some banks require a branch visit.
5. Make sure screen lock and find device are turned on on the device you're taking. How to set it up 10 smartphone privacy settingsIt is in

Preparation also includes reducing the number of times you connect to public Wi-Fi. Save offline maps from the Maps app, flight and hotel reservation confirmations, and travel insurance policies on your device so you'll be less likely to have to rush to find Wi-Fi at airports and hotels. The banking app checks that the certificate and authentication app are working properly by logging in once before leaving the country.

Step 3. Airport Wi-Fi: What order do I connect to?

For airport Wi-Fi, check the official network name, connect to Wi-Fi, complete the login screen, connect to VPN, and check status. The login screen is called a captive portal. A captive portal refers to a Wi-Fi login screen that opens the Internet only after agreeing to the terms and conditions or entering information. If the VPN is turned on first, your device may not be able to get to the login screen and it may seem like you have no internet at all.

1. Check the airport signage or staff for the official Wi-Fi name. If you see several similar names, select only the ones you see.
2. Connect to Wi-Fi. When the login screen appears automatically, complete the process, including agreeing to the terms and conditions.
3. If you don't see the login screen, make sure your VPN is turned off and try opening any website in your browser. It often takes you to the login page.
4. After confirming that the internet is open, connect from the StageVPN app.
5. Check the Connected sign and then use Mail, Messenger, or Banking apps. Data sent or received before the connection is complete is not protected by the VPN.

CISA's travel guide for the U.S. also covers Bluetooth and charging habits, along with public Wi-Fi. Turn off Bluetooth when not in use, and connect your charger directly to a power outlet if possible. If you take out your laptop, set the network profile in Windows to Public and turn off file sharing. These settings operate independently of the VPN, so you must check them separately even if you turn on the VPN.

Step 4. Local accommodation and on the go: what to look for?

Locally, logging into your property's Wi-Fi, choosing a server location, and checking the status when the network changes are key. Hotel Wi-Fi often requires you to log in with your room number and last name, and may require you to log in again after a few hours or a day.

1. When checking in, confirm your hotel's official Wi-Fi name and login method. Entering your room number and last name is common.
2. Follow the same steps as at the airport, go through the login screen first and then turn on the VPN. If your internet suddenly disconnects, your login session may have expired. Turn off the VPN for a moment and check the login screen first.
3. Choose a server location that suits your purpose. If your goal is to protect public Wi-Fi, select a nearby location or select automatically, or select Korea if you want to use domestic services as usual. Available locations may change and are therefore based on the listing shown in the app.
4. After changing from Wi-Fi to mobile data or losing signal inside a subway or building, check the app's connection status. WireGuard is designed to recognize the device and continue communication with the same public key even if the device's IP changes, but it is safe to check the status after the signal has been lost for a long time.
5. If the local map, transportation, or delivery app does not work with the VPN turned on, turn it off for a while before using it. Avoid sensitive tasks such as logging in and making payments while on the phone.

VPNs use slightly more data due to added encryption and headers. WireGuard adds 60 bytes for IPv4 and 80 bytes for IPv6 to each packet. Based on large packets of around 1,400 bytes, the increase increases by about 4 to 6%, and in communications with many small packets, the ratio can increase even further. If your roaming or eSIM data limit is low, set photo backup to only be done over Wi-Fi. If your VPN frequently disconnects after turning off the screen on Android, battery optimization may be limiting StageVPN. Things often get better if you turn off usage restrictions in the battery settings in app information.

A VPN also makes sense when using mobile data. For roaming, you can borrow a base station from a local telecommunication company, and for travel eSIM, there are products where the Internet connection point is located in a third country other than your travel destination. A VPN obscures the content and destination of communications in a route where it is difficult to know which service provider it goes through. To access domestic services using a Korean IP, select a Korean server. Even in this case, the policies of each service take precedence and use is not guaranteed.

Step 5. After returning home: what to bring back and what to erase?

After returning home, restore any settings you changed during your trip, erase any traces of your destination network, and check your account login history. If you leave your saved hotel/airport Wi-Fi on, it may automatically connect to a fake access point with the same name in the future.

1. Delete hotel, airport, and cafe Wi-Fi connected during travel from the list of saved networks.
2. I reapply for the bank's overseas IP blocking service that I canceled before leaving the country.
3. We summarize travel eSIM profiles and roaming additional services.
4. Check login history and security alerts for key accounts. If you have a device you don't know, log out and change the password.
5. If your subscription is only meant to be used during your trip, turn off auto-renewal at the place you paid. Even if you cancel, you can use it until the end of the payment period. Subscriptions paid for in the app market must be canceled at the relevant store.

This is also an opportunity to change plans if you plan to keep your subscription. Changing from monthly to annual will take effect immediately and prorated for the remaining period. Changing from yearly to monthly will take effect at the end of the current period. If you change payment platforms, updates to the previous platform will stop.
