We apologize for any disappointment caused! We provide travel eSIMs and their usage pattern is different from how you would use your home Wi-Fi.
However, please don't hesitate to contact our support team directly in the app. I'm sure they'll help you configure your connection to ensure the highest and most stable speed possible.
Very good app
Very good app. Very good internet coverage. And the best part- support group- always in contact, always helping. Recomend!
