First time I have used an eSIM so was a bit nervous re ensuring it was set up correctly so that I did not incur any charges so I had to email a couple of times. The response to my emails were very prompt and able to give me the guidance I needed. I was very impressed with the support and service given.
Thank you for sharing your experience! We understand the concerns that come with using an eSIM for the first time, and we’re glad our team could guide you promptly and clearly. It’s great to hear that the support and service left a strong impression — we’re always here to help whenever you need us.
Performed just as advertised in all 3 countries and I never experienced any slowdown or throttling. Finally…a product that does what it says!!!
We’re so glad to hear the eSIM worked seamlessly in all three countries. It’s great to know you experienced smooth, reliable service with no slowdowns. Thank you for sharing your experience, and we can’t wait to support you on your next trip.
I hate the speed control. When I opted-in, it was for unlimited data but without speed control. What a joke.
great value for the price. Connection is strong and stable, i had good internet everywhere.
We really appreciate your feedback. It’s awesome to hear that you’re getting great value for the price, with strong and stable connections everywhere. That’s exactly what we aim for.
Fine
