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.

The signal is unstable. After watching videos for a while each day, the signal becomes extremely slow, and even mobile payment functions become unusable.

For my recent trip to Japan, I chose this 4G/5G eSIM, and I'm so glad I did! What I love most is its convenience. No need to change SIM cards, no worries about losing my original one, and I could connect to the internet as soon as my phone landed – the whole process was incredibly smooth. Setting it up was completed in minutes after scanning the QR code, making it easy even for tech-savvy people. The network speed was amazing. Whether at popular tourist spots, in crowded shopping areas, or while traveling, the connection remained consistently stable. Checking maps, booking restaurants, and sending photos and videos to friends were all smooth and lag-free. It's incredibly reassuring for someone who likes to constantly check information and share their travels. The price is also very reasonable, and the number of days can be flexibly chosen according to your itinerary, making it perfect for independent travelers. Overall, it's convenient, stable, and offers great value for money – a network plan I'll definitely repurchase for future trips to Japan.
