I installed everything according to the instructions. There were no complications. I also installed it in Russia before my flight. Once I arrived, everything connected quickly and easily. The internet lasted for 10 days; you can get less GB. So, everything is fine.

The signal in Seoul is good and stable, and the coverage is also acceptable. It’s easy to install — you can set it up before your arrival, but make sure to turn off the line and do not activate it yet. For my usage, 4–5 days with 10GB is sufficient for browsing and navigation.

The best e-SIM. I had a different one before and switched to this one. I'm happy with it. I had a number, could make calls, and had unlimited internet access. I was delighted, and next time I'll get this e-SIM too. It was a great experience.

I used this for four days during my trip to Korea. I usually use WiFi, but this time I tried this service. It was easy to set up and I just had to switch it on when I arrived, so it was very convenient. I was able to use it on the subway and everywhere else without any problems, so I'd definitely use it again when I travel!
