Solid eSIM for South Korea. Used it mainly for work emails, video calls, and navigation during my business trip. Coverage was excellent in the cities. Price was very competitive compared to other eSIM providers I checked.

This was my first time using an eSIM and I was a bit nervous, but the process was incredibly simple. Bought the plan the night before my flight to South Korea, installed it in under a minute. Worked perfectly the entire group tour. Will definitely use again.

Bought eSIMs for our whole family for South Korea — the family pack discount saved us quite a bit. All four phones connected without any issues. Kids were happy they could use their apps, and we didn't have to worry about roaming charges.

Reliable service during my work conference to South Korea. Appreciated that the data validity starts when you first use it, not when you buy it — so I purchased it a week early with zero waste. Would recommend to anyone traveling to South Korea.

Used TripoSIM for my backpacking trip to South Korea. Setup took 2 minutes — scanned the QR code at the airport and had 4G immediately after landing. Speeds were great for maps, video calls, and uploading photos. Much cheaper than my carrier's roaming package.
