Bought the eSIM via WAUG right before landing in Hanoi. QR code came right away, scanned it, and boom — connected! Used it for maps, Grab, and IG all day with no issues. Highly recommend for solo travelers.

What to Remember
Don’t forget to check all the important details.Cancellation and Refund
Refunds are available within 7 days of purchase.
However, refunds processed in the following month may be difficult, and refunds are not possible if the product has been used or already registered on your device.
Due to the nature of products used overseas, refund requests due to activation failure, unavailability, or eSIM defects may be due to issues with the device in use, unfamiliarity with settings, or temporary communication failures, rather than product issues. Therefore, refunds will only be processed upon approval after consultation with customer service (phone, email, KakaoTalk) using local Wi-Fi or similar.
Refunds requested after returning home without prior confirmation may not be processed.
Cancellations/refunds are only applicable to requests received during business hours (Monday-Friday, 9 AM - 6 PM).
