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

The signal and network speed are both great. I don't know how those negative reviews came about. I'm using an iPhone 17 Pro with this eSIM and the experience is excellent, including in Seoul. I also went to Busan and the signal was still great. The key is the affordable price. I'll definitely buy this again next time I go to Korea.

Reviews: South Korea SKT eSIM | Unlimited Data + 010 phone number | 1-90 days | 24-hour billing | QR code
Guest User2026-06-02
esim was simply effective. coverage was crazy stable no matter where i was, and phone number came in handy for restaurant reservations and signups :) 100% recommended and fuss free with the one-tap install too. however, have to sign up with your passport on another site once during office hours, so might be tough for those who arrive in korea at late timings~

Reviews: Asia 10 Regions 5G eSIM | Multi-Network • ChatGPT | 1–30 Days | QR Code
Guest User2026-06-02
I had a great experience using this eSIM. The activation process was quick and easy, and the connection stayed stable during my trip. Internet speed was good for maps, social media, video calls, and streaming. It saved me a lot of time and money compared to buying a physical SIM card. Customer support was also responsive when I had questions. I would definitely use this service again while traveling.

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 User2026-05-28
I bought a 5G plan, but for some reason, my 5G-enabled phone only shows as 4G+ in Korea. I tried three phones: a Vivo showed 4G+, a Huawei showed 4G, and an iPhone 11 showed LTE. The 4G+ signal was very stable and sufficient, so I didn't contact customer service (the staff at the activation counter also didn't know why it wasn't showing 5G). When activating it at the LG U+ counter at the airport, the staff asked if I wanted to purchase more call minutes. I thought about it and decided not to, since I didn't need many. And indeed, I didn't need them; receiving calls and verification codes was enough. After inserting the data SIM card into my phone, I could top it up at the subway station. The design is very nice, much nicer than the regular T-Money cards sold in Korea.
