Reviews: South Korea 5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | 1-30 Days | QR Code
Guest User2026-01-28
Signal was very strong throughout the entire trip in Seoul. There are a lot of free wifi spots in Seoul (such as buses, train stations), so 2GB/day was plenty for us.★

Reviews: South Korea | 5G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code
Guest User2026-01-27
I always use this eSIM, which is the cheapest. The QR code is sent immediately via email, and it's very easy to use. The signal is good in Korea, but the only inconvenience is that I can't view photos on Naver Maps. While this may not be the eSIM's fault, I can view photos when I connect to public Wi-Fi in Korea.★

Reviews: South Korea 5G eSIM | Dual Network Coverage | ChatGPT | 1–30 Days | Instant QR
Guest User2026-01-28
First time using eSIM, so the initial installation asked customer service 10 points friendly quickly answered the question! It turns out that installation 10 points easy, after installation to the local open roaming to use, more convenient than the previous SIM card replacement, stable and fast connection, good coverage of the place will not be received, GB number is enough! Will repurchase again next time!★

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!★

Reviews: [South Korea] SKT Native Card|unlimited data|Includes local number|3–90 days|4G SIM cards|Pick up at South Korea airport
Guest User2026-01-25
Using the SKT SIM card in South Korea during this trip was a very stable experience overall. The network connection was fast, and I hardly encountered any disconnections or lag in the city, subway, or major tourist attractions. Navigation, researching information, and uploading photos were all smooth, and it handled everyday use without much difficulty.
The installation and activation process was intuitive; simply follow the instructions. It's very user-friendly for travelers. Hotspot sharing worked normally during actual use, which is convenient for those who need to connect multiple devices.
The only thing to note is that different plans have different restrictions on call and SMS functions. If you need to receive verification codes or make calls, it's recommended to check the plan details beforehand.★

Reviews: South Korea SKT eSIM | Unlimited Data + 010 phone number | 1-90 days | 24-hour billing | QR code
Guest User2026-01-25
This is my second time visiting Korea. I also used this service on my previous visit. Unlimited data is something no other carrier offers, so it's very useful. However, the signal strength can be poor from 2:00 PM to 4:00 PM, but as long as you can tolerate that, it's an eSIM that works without any issues.
