Good price, easy setup. Thank you!
Thank you for the great review! We’re happy to know you enjoyed the pricing and had a smooth setup experience with our eSIM service. We truly appreciate you choosing us.
Perfect
Thank you so much for your feedback! 😊
We’re glad to hear everything worked perfectly. If you need any assistance in the future, feel free to reach out.
very similar price to a WiFi hotspot unless the WiFi hotspot is being used for many people. Connection was mostly 4G in the Central Japan area. Receiving and sending were fast, including photos and videos. One suggestion, particularly for first time users if they are not really smart phone savvy is to have a “one page” pdf instruction sheet summary that can be downloaded from how to order, activate and then disconnect when returning home. The information is all on the website but in different places. I created my own one page instruction sheet that I will share with friends who want to try an eSIM. I’m switching over from using a WiFi hotspot to eSIM for future trips. thank you.
Thank you so much for sharing your detailed and thoughtful review!
We’re glad to hear that you found the connection reliable in Central Japan and that data speeds worked well for sharing photos and videos. It’s also great to know that the eSIM experience has encouraged you to switch from a WiFi hotspot for your future trips.
We truly appreciate your suggestion about providing a one-page PDF instruction sheet, especially for first-time or less tech-savvy users. Your feedback is very valuable to us, and we’ll certainly share this with our team as we work on improving the overall user experience.
Thank you again for choosing our service and for recommending it to your friends. We look forward to supporting you on your future travels!
