Choose your South Korea plan

Fixed 5GB suits lighter use between Wi-Fi connections. Essential is the balanced daily option for a two-week trip; Plus gives more daily high-speed data for heavier uploads or sharing where hotspot is supported. Compare the allowance, duration and price against your expected use before choosing.

Prices may change. Always check the product page for the latest prices before purchasing.

How daily Unlimited works

• Unlimited Lite: 1GB/day high-speed, then up to 512 kbps.
• Unlimited Essential: 1GB/day high-speed, then up to 1.25 Mbps.
• Unlimited Plus: 2GB/day high-speed, then up to 2 Mbps.

Standard Unlimited options are Lite. Lite, Essential and Plus are selectable for 1, 3, 5, 7, 10, 15 or 30 days. High-speed allowances refresh daily; reduced speeds apply for the rest of the day after that day's allowance is used. Unlimited does not mean unrestricted high-speed data. Fixed plans end when their total allowance or validity runs out, whichever comes first, without reduced-speed continuation.

South Korea coverage on SK Telecom

The listed partner is SK Telecom, with 4G/5G support. Available technology and speeds depend on your selected package, device and local conditions; 5G is not guaranteed everywhere.

City transit, KTX journeys and Jeju routes

Keep tickets, accommodation details and maps offline for Seoul Metro rides, KTX journeys and remote Jeju or mountain routes. Signal can drop in tunnels, underground or away from populated areas. Confirm essential remote locations before buying and arrange appropriate backup communications where needed. A larger allowance does not extend coverage.

Mobile data does not guarantee that every local booking or navigation app will accept a foreign account or work without a Korean phone number. This plan does not provide Korean SMS identity verification.

Hotspot and data-only service

Hotspot sharing is available where supported by your device and network. Shared usage counts toward the same total or daily high-speed allowance and speed limits. Confirm selected-plan sharing terms before buying if tethering is essential. Large uploads, backups and streaming can use data quickly.

This eSIM does not include a Korean number, ordinary calls or SMS. Internet-based messaging and calling depend on connectivity and app availability. If keeping your home SIM enabled, check its roaming charges, turn off its data roaming and avoid automatic mobile-data switching.

Compatibility, installation and activation

1. Check that your exact device model and regional version support eSIM and that the device is carrier-unlocked.
2. Install the emailed QR code over stable Wi-Fi through your cellular or SIM settings, following your order's instructions. Keep the QR private.
3. When ready in supported South Korean coverage, enable AloOui, select it for mobile data and turn on its data roaming as instructed.

Validity starts when the eSIM connects to a supported South Korean network, not QR delivery or installation alone. If already in South Korea, enabling the line and connecting can start the plan. Follow your purchased option's activation deadline and expiry instructions.

APN, connection help and support through the Help Center

1. Check that AloOui is enabled, selected for mobile data and has data roaming on.
2. If manual APN setup is needed, enter data.esim with username and password blank, then save/select it. Some devices configure this automatically; follow your order if its settings differ.
3. After installation finishes, toggle airplane mode briefly or restart. Try 4G/LTE if 5G is unstable.
4. Start with automatic network selection; if needed, select SK Telecom according to your order or support's instructions.
5. Check remaining data and validity. Keep the eSIM installed while troubleshooting.

Ask support before deleting the profile, changing devices or rescanning the QR code; do not assume transfer, reinstallation or QR reuse is supported.

AloOui provides customer support through the Help Center. Share your order number, exact device model, location and error privately.

Check every stop and the regional product's own allowance, validity, networks and current price before buying. It is a separate purchase, not extra coverage included with this South Korea plan.
