Digital Environment and Connectivity in Vietnam: real experience from chats
From real experience
how-toWhen installing a Vietnamese eSIM (e.g., Viettel) purchased via Trip.com, a network error during the activation process can render the QR code 'already used' without actually adding the profile to the device.
In this case, users should contact Trip.com support immediately. Despite non-refundable policies, support frequently issues a new QR code or processes a full refund. Disabling the physical SIM card during eSIM setup can prevent activation errors.
