It was my first time traveling to Asia and I was really worried about the connection. It turned out I was completely unfounded!!! The SIM card quality was SUPERB! The internet was flying! I didn't have to contact customer support, hurray.

I used this service for a 3-night, 4-day trip to South Korea. It was my first time in Korea, but it was incredibly convenient, and I had no problems with internet access during my trip. I didn't use the phone function, but having a phone number associated with it gave me peace of mind in case of any issues. I would definitely use it again when I go to Korea.

Buying a virtual card is easy. Installing it was a bit confusing at first. We received a few. Just enable roaming on the virtual card and it's up and running. It works well everywhere, even on the subway. 5G. I highly recommend it.

Naver Map has low latency for small detours and navigation switches. The wide range of plans helps me avoid overbuying data.
