Lite, Essential and Plus have selectable durations up to 30 days. Premium is not listed among this product's selectable variants. Review the specific plan terms and current price before checkout.

Use data around Busan

Plan your route into the city, check metro connections and keep lodging details handy while visiting Haeundae, Gwangalli or markets. Save your accommodation pin and key bookings offline before navigating crowded stations or underground stretches where service may vary.

Busan to other Korean destinations

If you are continuing by train to Seoul or visiting Gyeongju, choose validity covering the entire route. Download tickets and offline maps before boarding, since mobile signal can drop in tunnels. For island trips, check the chosen plan's destination coverage and allow for variable signal during ferry travel.

Set up before arrival

1. Confirm your exact device is eSIM-compatible and carrier-unlocked.
2. Choose a total allowance or daily tier for your full South Korea trip.
3. Install over stable Wi-Fi using the QR code emailed after purchase.
4. On arrival, select AloOui for mobile data and follow activation guidance. Review roaming on your home SIM to avoid unwanted charges.
