Guest Guest “The 4 eSIMs I bought for my whole family for our trip to Japan worked flawlessly throughout the entire trip, including Tokyo, Kyoto & Osaka. The wireless service often faster than the free Wi-Fi in some of the hotels!”
Guest Guest “I used it for a week. Internet was fast and decently priced. Rather easy to install too. No real complaints. ”
