Ratings and reviews

the app is almost good 👍 but it needs to press "more" many times to see countries which is inconvenient. prices - some good some not. • One more thing to fix: even though I switch to EUR currency, the prices are still shown in USD - this needs to be fixed.

It just works. Support team is very responsive and helpful. Used their data-only eSim for travel on several occasions for a couple of years.

I'm really satisfied with unisim. The price is always much much lower than the usual sim card I pay. the support works very fast and helpful 100%. if I could I put 10stars
