Customer Reviews

Inexpensive, easy to set up, and excellent support... I had no complaints at all. This time I used it in Taiwan, and I will consider this provider first the next time I go abroad.Translated from Japanese.
Very easy installation, very good speed and different network, 5G coverage and very good value for money
I had been using eSIMs from other providers, but even the ones advertised as unlimited would slow right down after about 5GB in a day. I tried Xiao Long's eSIM half expecting the same, but the speed held up past 5GB, and even past 7GB I was still watching Netflix at the highest picture quality. I was genuinely surprised, and it is inexpensive too. I will keep using it.Translated from Japanese.
As you may know, mainland China runs on QR code payments. It is no exaggeration to say you cannot even go shopping without mobile data, so you really want a connection that works from the moment you cross the border.
On my last trip to Shenzhen I used up the mobile SIM I had bought in Hong Kong and ended up rushing to Luohu Station to buy another. Getting by on public Wi-Fi, the way you might in Japan, is hard work. Whether or not you have a connection you can rely on makes a real difference to the trip.
This time I used Xiao Long's eSIM. Two things sold me on it: I had been reading about it on Twitter for a while, and there was a truly unlimited plan. That second point matters, because throttling is a nuisance and slower speeds spoil the experience. I am not exaggerating: keeping your bandwidth really does matter.
There was one more thing worth recommending, and that is how quickly support responds and how well they solve things.
After crossing the border I confirmed the connection and used a ride-hailing app straight away. The ride itself was fine, but my connection dropped as I was getting out and I nearly had a dispute with the driver, though we managed to sort it out.
Losing the connection is a real problem, so I contacted support once I reached the hotel. They dealt with it the same day and even looked into the cause. When the internet matters, support matters. For all of these reasons, this is an eSIM I can recommend with confidence. Thank you.Translated from Japanese.
I used it for four days in Seoul and at Yeoju Premium Outlets.
First of all, setting up the eSIM was very easy and I was up and running smoothly.
The connection was fast on the ground and comfortable to use even while moving around. Video calls on LINE in particular were excellent for both sound and picture, with no stress at all. Because it is truly unlimited, I could use it without worrying about how much data I had left.
I think this is a great eSIM for a trip to Korea. I would love to use it again next time.Translated from Japanese.
I bought it before my flight and it worked right after landing. The connection held up all the way from the airport to the industrial area. I could listen to Amazon Music and YouTube Music, watch Netflix, and the flat price was reasonable too. When I happen to watch Netflix on the TV and a video on my phone at the same time, a speed-boost option would be a nice addition.Translated from Japanese.

I'm currently living in China for work.
I usually watch content through a VPN, but the VPN connection sometimes becomes unreliable, so I was looking for an easy-to-use eSIM just in case.
It works without any problems.
Now I can feel at ease even when the VPN isn't working.Translated from Japanese.
