I was traveling from Canada to Brazil. The whole process of purchasing, installing and activating the eSim on my Samsung A56 5G was simple, easy and fast. Highly recommended.

This was my second time using data like this. I enjoyed the experience again. It was easy to realize that a quick YouTube video could help solve any issues. The data I used while in the country functioned similarly to how I use it in the States, but my battery kept draining, probably because I was traveling around the country a lot. Still, I really enjoy this service.
