I've repurchased this multiple times. It's ready to use immediately upon arrival, and renewals are very convenient. Checking usage on the website is easy, and data sharing is supported. Internet connectivity is consistently smooth across different locations in Spain.

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.

This is my second time buying an e-SIM with this offer. I bought it for my wife for the remaining couple of days in Paris. Everything worked flawlessly, too. Very easy and inexpensive. I recommend it. We received a credit card number, scanned it, and the e-SIM was added. We enabled data roaming on our iPhone, and everything worked in a minute. The SIM card worked in Italy, France, and even during our layover in Istanbul, it worked without a problem. Very convenient.

I used it in China and Sri Lanka. I downloaded it in China, but I couldn't use it properly. I got help from a Chinese guy in his 20s, and luckily I was able to connect just as I left the express train's Wi-Fi area. I think it's important to check if it works at the airport and when the airport Wi-Fi is cut off, but I think it was a good idea. I extended my trip, so I purchased it for a slightly longer period, so this was also good.

I used it on a trip to Spain, Italy (Vatican City), and France. It occasionally dropped to LTE, but the signal quality was generally good. It was very convenient.
