Line is fast and reliable. Very affordable price for short trip. Activation took less than a minute. Once you landed you will have your line.

Reviews: South Korea SKT eSIM | Unlimited Data + 010 phone number | 1-90 days | 24-hour billing | QR code
Guest User2026-02-09
It's easy. I've had issues with cheap SIM cards in the past, but this one is genuine, so I feel safe. I was able to use it right away after it arrived, and there were no problems with the signal. So, although I don't know how the customer center will handle it, I'll definitely use their services again.

Reviews: South Korea 5G eSIM | Daily/Total | 500MB/day - 30GB total | 1-30 days | 24-hour format | QR code
Guest User2026-02-09
I used it in Korea. After arriving in Korea, I realized that the eSIM I had already reserved wasn't enough, so I reserved a new one, which I received an email for immediately. There was a QR card, but when I clicked on the installation URL, it asked me if I wanted to activate it. I selected it, turned on data roaming, and it was ready to use right away! I thought 500 yen for 5G per day was a bargain. With 5G per day, I had plenty of data to search on Instagram and watch videos.

These eSIM cards are a great idea. No need to bother with buying physical ones anymore. Have you tried buying and registering a SIM card in the Philippines? Our friends tried, and it took a terribly long time. Overall, if your phone supports eSIM, I highly recommend buying it here. It's less hassle and cheaper.
