The signal is excellent. I was driving through Sapporo, Toyako, Hakodate, Niseko, Asahikawa, and Furano, and I could still use Google Maps to find information.

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.

I purchased it in advance, and when I had some questions about setting it up, I contacted them via chat and they responded quickly and solved the problem. I was able to connect immediately when I arrived in Korea, and I was able to use the internet comfortably without any issues during my trip. I would like to use it again next time.

Using the SKT SIM card in South Korea during this trip was a very stable experience overall. The network connection was fast, and I hardly encountered any disconnections or lag in the city, subway, or major tourist attractions. Navigation, researching information, and uploading photos were all smooth, and it handled everyday use without much difficulty. The installation and activation process was intuitive; simply follow the instructions. It's very user-friendly for travelers. Hotspot sharing worked normally during actual use, which is convenient for those who need to connect multiple devices. The only thing to note is that different plans have different restrictions on call and SMS functions. If you need to receive verification codes or make calls, it's recommended to check the plan details beforehand.

I've been buying this eSIM for two trips in a row now. It's a reliable, uninterrupted connection with smooth coverage. I highly recommend it! 👍
