Reviews: [South Korea] LG U+ Combo Card | Unlimited 4G/5G SIM + T-money Transportation Card (from 3 days) | 1–90 Days | Pickup at Incheon, Gimpo, Gimhae Airports
Guest User2025-11-25
I didn't use the call answering function, and I'm not sure if it's activated or not, but the internet speed is definitely fantastic. I'll definitely buy this again next time I go. The card pickup and installation at the airport are extremely convenient. Highly recommended!
It's definitely worth buying; you get what you pay for. The counter is easy to find, and the staff's service is superb. Even though we speak different languages, they made sure you understood. The card is also great for taking the subway and buses; a quick swipe is super convenient and saves you from carrying multiple cards. I can use this again next time.★

Guest User2026-01-26
The SIM card worked perfectly from the moment I inserted it. Fast and stable internet, good coverage both in cities and during trips. I had no issues with connection or speed, even when using maps, social media, and video calls.
Very easy to activate, no additional setup required. Definitely recommend for travelers visiting Korea.★

Reviews: [Free T-money | Korea SIM Card] SKT 4G/LTE High-Speed Data + Call SIM Card + Daiso e-coupon Giveway (Available at Korea Airport/Seoul)
Guest User2026-01-19
In Incheon (Terminal 1), there are counters at various points on the first floor where you can pick up your card. Processing is quick. I couldn't connect to it myself, but a staff member quickly helped. I had no internet issues during the week. Everything went perfectly.★

Reviews: Asia 9 Destinations 5G eSIM | Japan, Thailand, Vietnam, Indonesia, Korea & More | 1–30 Days | Instant QR
Guest User2026-01-11
I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.★

Reviews: South Korea | 5G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code
Guest User2026-01-25
I usually use an unlimited eSIM with a number, but I purchased this for the first time for my two-day stay. I haven't used it in crowded situations like concerts, so I'm not sure, but I didn't have any problems with the signal for normal use. It's not suitable if you need a Korean phone number, but if you don't need a phone number, it's good value for money and I don't think you'll have any problems! I haven't used customer support, so I don't know.★

Reviews: Global (100 countries) 4G/5G eSIM | DayPass/Total | 500MB/day - 30GB Total Data | 1-30 days | 24-hour billing | QR code
Guest User2026-01-25
Excellent SIM card. We used it in the UAE and Oman. We got the 1GB per day plan—it was always enough for both internet and navigation. Search doesn't work well in tethering mode, but social media works fine. It's very easy to set up, the signal is good, and we're completely satisfied with the service.
