Reviews: South Korea 5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | 1-30 Days | QR Code

I purchased a 4-night, 2GB daily plan. I used Wi-Fi at the accommodation. Outdoors, I used maps, web searches, Google Translate, and occasionally Instagram. The speed never slowed down, and it was very comfortable! I didn't use customer support this time, so I'm giving it an average rating.

Upon arriving in Busan, there was no Wi-Fi available to activate my eSIM right after disembarking, which made me a little nervous (because I needed to use Uber later). After clearing customs, I found Wi-Fi in the airport terminal, though the signal wasn't very stable, and I could activate my eSIM there. I spent five days in the west side of the airport, and while the signal was unstable for a few short periods, it was generally good. A friend suggested activating the eSIM while there's a Wi-Fi signal in Taiwan so it's usable upon arrival, but this might start the activation time earlier, so it's a matter of personal preference. I would definitely consider repurchasing it later.

Reviews: South Korea SKT eSIM | Unlimited Data + 010 phone number | 1-90 days | 24-hour billing | QR code
Guest User2026-03-15
Registration was easy, and it worked without any problems! I chose this because I wanted a phone number, but because I arrived early in the morning, I couldn't complete the verification process, so I had to go to a manned counter to have it set up so I could receive messages! It didn't take long, and they did it right away, but be aware if you arrive before 8am and want to use it immediately!

Guest User2026-03-17
The internet is good, fast, strong, and uninterrupted, usable in all areas: on the mountains, outside the city, on the train, in crowded areas. Paying this price, with easy, convenient, and fast installation—just click once—is worthwhile. If you're going to Korea, get it. It's worth it.
