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.

During a two-week trip to Portugal, I decided to try an eSIM and ordered it directly through Trip.com. The process was simpler than I expected: after payment, I immediately received a QR code via email, and the Trip.com app clearly explained how to add the profile to my iPhone. The speed was quite comfortable, sufficient for both maps and calls in messaging apps. The only thing is, it's best to activate it in advance.

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.

eSIM in 30 seconds: 🔥 Great: Activation in a couple of clicks in the app. When traveling, you can buy an internet package before leaving the plane. Frees up space on your phone. I've decided for myself: If I travel often, this is an indispensable thing.

The card was functional only in FRANCE. Check well and claim before. What I recommend... Take a map directly with your destination COUNTRY. La carte était fonctionnelle uniquement en FRANCE. Bien vérifier et réclamer avant. Ce que je recommande… Prenez directement une carte avec votre PAYS de destination.
