I would highly recommend Travelkon for anyone looking for an eSIM
I would highly recommend Travelkon for anyone looking for an eSIM. The customer service was absolutely fantastic where we were able to get help while overseas via WhatsApp. They even supplied me with a temp eSIM when I was having issues with my verification in Hong Kong. 10/10 😊
