Customer Reviews
Easy setup for USA trip
I needed an eSIM for my US trip, so I picked up the USA travel eSIM. It was pretty straightforward to get it going, just followed the instructions. Had good signal most of the time, though it was a bit slow in one small town in Colorado. Overall, it did what I needed it to do for calls and maps. No big drama, which is always good.
Worked perfectly in Europe
I got the Europe 33 countries eSIM for my recent vacation and it was fantastic! Super easy to set up, and I had data everywhere I went, from France to Italy. I didn't have to worry about roaming charges at all. I definitely will shop here again for future trips!
Good value for Japan travel
I was looking for the best deal for my trip and the Japan unlimited data eSIM caught my eye. The price was competitive, especially with a small discount I found. It worked great the whole trip, felt like a solid purchase for the money spent.
