Each QR code can only be scanned once by one mobile phone. Once bound, it cannot be changed to another device or deleted. Once deleted, it cannot be re-scanned and installed, and a new purchase will be required. If the eSIM is already installed, please do not remove it.
If an error message is displayed after scanning, it does not mean the eSIM is invalid. Please restart your phone and go to [Settings > Mobile Services] to check if the eSIM has been added. Alternatively, contact customer service for assistance. Do not scan other QR codes, as this may result in multiple eSIMs being installed on one phone.
Installing an eSIM requires internet access; it is recommended to install it before departure or by using the free Wi-Fi at the airport at your destination.
Please remember to turn off data roaming on your original SIM card to avoid using the original SIM card's mobile network and incurring high roaming charges.
You can install an eSIM before arriving at your destination, and activate the plan upon arrival; the usage period will then begin.
Days are calculated in calendar days. The first day is considered to be from the date the eSIM is activated until 23:59 (GMT+7) on that day. (If a user purchases a 3-day data plan and activates it at 10:00 AM on September 1st, this plan will terminate at 23:59 on September 3rd.)
The local eSIM provided by Viettel may display "Activating" when used outside of Vietnam. Upon arrival in Vietnam, please activate this eSIM; it will automatically connect to the network. Please disable data roaming and set your mobile data to this eSIM.
eSIM usage check: Send the text message "KTTK" to 191.
Please delete the profile on your iPhone (check steps: Settings -> General -> Device Management, scroll to the bottom; if there is no profile, it is normal), to avoid problems with smooth operation.
