I was able to use it comfortably, so I recommend it. I got the 100GB per day plan, but I only used LINE, maps, and store search, so I didn't actually use even 1GB per day (lol). It's also helpful that you can check your current usage. I'll use it again next time.

We had some problems with installing the e-sim, but trip.com customer service came to rescue and everything is good and well. Signal is good too.

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've used it several times. At first, I was a little worried because it was so cheap, but it's been working without any issues. 😊 Setup is easy; just press the download button on Drip.com. Then, when you arrive at your destination, switch to the main line at the airport and turn on roaming. It's very useful. ♪

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.
