Guest User2026-03-31

The staff responded to chats quickly, but some didn't check the information before responding, resulting in inaccurate details. The internet signal was excellent and uninterrupted. Highly recommended!

★

Guest User2026-03-15

It's very fast, powerful, and stable. Easy and hassle-free installation. Say goodbye to constantly removing and inserting your travel SIM card. The price is also reasonable.

Guest User2026-03-30

I usually use an unlimited data plan, but I thought a 1GB/day plan might be okay for my child, so I tried this cheaper option. I set it up in Japan and was able to use it as soon as I arrived in Korea. It wasn't particularly slow and worked without any problems. I would like to use it again next time.
