The eSIM worked perfectly after I downloaded and activated it. I had no issues with the installation or the connection. I was also able to extend my data after using up my original allowance, and the process was seamless. The additional data was activated right away, and I had no issues at all. Everything worked perfectly

A very useful card for traveling abroad! Inexpensive! If you can't find Wi-Fi, this card will help you out.

I highly recommend this app! It's fast and cost-effective. When you're about to lose internet access abroad, just turn it on and you'll have internet again instantly. It saved me from almost getting lost and stranded overseas! I suggest buying it in advance without installing it, and then turning it on when you feel your mobile internet is about to disappear.

This is great! I was glad I bought this, it gave me a phone number in France and very convenient to register for apps in Europe (Volt, Uber eats and other transportation apps in Hungary and Prague). Great connection

A great eSIM that delivered exactly what it promised. The installation process was simple, activation was seamless, and I was connected within minutes. Data speeds were consistently good, and the connection remained stable throughout my trip. An efficient, reliable, and convenient option that I would happily use again.

It's easy and convenient to set up. I found a connection in Paris immediately upon arrival. We haven't used the package in other countries yet, but I think it will be great. This isn't our first time using a mobile service, through Trip.
