I bought 3gb/per day and it was more than enough. I activated the esim before my arrival. I never had any problem with it, except for when I arrived, the esim didn't work immediately and I had to restart my phone

Excellent eSIM! I used it while traveling through Serbia and Montenegro. The signal quality and connection speed were excellent even when changing countries. Setting up was also very easy. It was my first time using an eSIM, and frankly, I was worried about how it would work! Turns out I needn't have been. Just follow the instructions.
