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.

Installed quickly before departure, connection quality was good, I only occasionally had no network, but that was also the case for my friends with local SIM cards, so I think it's due to the infrastructure and not the eSIM.

I liked Esim. It's my second day in Spain, and everything works fine. Installation was easy, everything was clear, and the instructions were detailed. I installed it in Russia the day before to avoid any hassles at the Turkish airport. I was a bit stingy and bought 3GB for each day, but so far I've only used 1GB in two days.

I bought it before my trip to Europe. Everything worked fine. The main thing is to enable data roaming on your phone and manually change the carrier in Redis for each country. I bought 100 GB. It was more than enough.

In simple words it’s outstanding, I used it in Malaysia where it worked outstandingly then I used it in Dubai and later on I’ll use it in Europe, however I haven’t experienced it in Europe yet, I am pretty sure that it’ll work perfectly over there as well. Highly recommended. I purchased it in china, I have 3 days package 1GB daily. The price is also reasonable
