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.
