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.

Drei is the carrier. It works great, it's easy to set up (scanning a QR code installs the SIM card right away), and I've tested it – it has a good signal and good speeds in Turkey, France, and Spain. I'll buy more when I need them.

My first eSIM! It was so convenient!!! I used it when traveling to Saudi Arabia. There was Wi-Fi at the airport and hotels, but I think you need to be prepared when traveling around town. Pocket Wi-Fi would be a bit of a hassle to carry, and I wasn't sure if I could buy a SIM card locally, so I bought an eSIM. I previously purchased an eSIM from another place, but I had trouble using it. This time, the instructions were detailed, the installation was easy, and after a little setup once I arrived, I was able to use it without any problems! It was so convenient that I'll definitely buy from here again!

Booked this sim card for my wife and myself. The best e-sim card covering parts of Europe so far.
