Pocket Wi-Fi prices in South Korea
| Rental | Price | Data | Deposit |
|---|---|---|---|
| KT WiFi Router | 4,400 KRW a day (about $3.32), or 55,000 KRW for 30 days | Unlimited at 20 Mbps; several devices | Credit card in your name (no debit cards), passport |
| LG U+ Pocket Wi-Fi | 4,400 KRW a day (about $3.32) | 4 GB a day of LTE, then up to 5 Mbps; up to 10 devices | 1,111 KRW card authorization, or 70,000 KRW on a debit card |
Both are picked up at Incheon Terminal 1 or 2, Gimpo or Gimhae. LG U+ takes the router back at any of those counters; KT's routers run 9.5 to 30 hours on a charge depending on the model, and KT rents at most four per person.

A South Korea eSIM is installed at home on Wi-Fi and works when you land, with no counter, no deposit and nothing to return. Going on to Japan? Japan and South Korea on one eSIM compares the options.
When pocket Wi-Fi is the better pick
- A group of four or more sharing one connection all day: one router splits the cost.
- A phone that is carrier-locked or has no eSIM.
- Laptops and tablets without mobile data (an eSIM can share a hotspot too, but the phone then does the work).
Lost or damaged routers are charged; LG U+ refunds the charge only if the device turns up within 14 days. Set a reminder for the return counter on your last day.
