No issues at all
I bought it for half the price of other service providers, used it on a trip to Copenhagen in April 2025, and had no problems. I just have to recommend it. I was very satisfied.

Kudos to whoever did this
Kudos to whoever did this. I had no problems at all, I downloaded the program a week before going abroad. I chose the country I was going to and bought an internet package. It said it was waiting for activation. I started using internet as soon as I enter

Great price and smooth connection
I travel a lot and always use eSIM io. It is affordable, easy to install, and works everywhere. Very practical for those who travel a lot. I definitely recommend it.

Amazing!
I bought 10 gb data for around $13. I use it in Germany. It is very efficient and was activated immediately. I felt the need to write this just as a guide for new users. iOS users, turn on international roaming from the settings when installing, otherwise

It is a very nice application
It is a very nice application, it gives you $5 on your first login, which means you get 3GB data for free (for 30 days) It will come in handy in difficult times, thanks again eSIM♥️
