Will my eSIM work as soon as I land in South Korea?

Yes — install it at home on Wi-Fi before you fly, then switch the line on when you land. It joins a partner network in South Korea automatically, usually before you reach baggage claim. Your days only start counting at that first connection.

Do I keep my own number and WhatsApp in South Korea?

Yes. This is a data-only eSIM that runs alongside your home SIM. Your number stays active for calls and texts, and WhatsApp keeps working on your usual number the whole trip.

When do my days start counting?

Only when the eSIM first connects to a network in South Korea — not when you buy or install it. Buying ahead of your trip is completely safe.

Which phones work with a South Korea eSIM?

Most phones from 2018 onward: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, plus many recent Xiaomi, Oppo and Motorola models. Your phone must also be carrier-unlocked — check yours in 30 seconds on our compatibility page.

Can I hotspot my laptop or tablet in South Korea?

Yes — tethering is included wherever the local partner network allows it, at no extra cost. Handy for sharing data with kids' tablets or getting a laptop online.

How much does a South Korea eSIM cost?

Unlimited data from £2.35 per day — the longer the trip, the lower the day rate. A one-week plan starts from £3.28 in total, always shown in full before you pay. No roaming charges can ever appear afterwards.

The South Korea eSIM guide.

A travel eSIM is the simple way to stay connected in South Korea: unlimited data at a clear per-day price, delivered as a QR code the moment you order. No airport SIM queues, no roaming bill when you get home, and your own number stays live for calls and WhatsApp the whole trip.

How it works on the day

Install the eSIM at home on Wi-Fi — it takes about two minutes — then switch the line on when you land in South Korea. It connects to a partner network automatically, and your days only start counting from that first connection.

Choosing your days

Short breaks run at the standard day rate, and longer Asia trips earn an automatically lower rate from 7 days up — with the deepest discount at 30 days. From £2.35 per day, unlimited.
