Reminders
eSIMs must be activated within 30 days of issuance. It is recommended to activate them immediately upon arrival to ensure proper use. Or install in advance and turn on the eSIM after arriving at the destination
If you need to manually add an eSIM, please refer to the detailed information in the "Pre-departure Reminder" and copy and paste the SM-DP Address and Activation Code into the designated box. You do not need to enter the confirmation code.
If you install an eSIM before arriving at your destination and see "Activating" or "Unable to activate eSIM," do not delete the eSIM. Instead, temporarily disable the eSIM and then re-enable it after you arrive.
If an error message appears when scanning the QR Code, it does not mean that the eSIM has expired. Please go to "Settings → Mobile Services" to confirm whether another SIM card option appears.
No refund will be provided if some applications are unavailable due to device compatibility or regional restrictions; no additional compensation will be provided, including roaming fees, transportation fees, etc.
The Viettel eSIM QR Code is for single-use installation only. After installation, please do not delete the eSIM. If it becomes invalid due to deleting the eSIM, resetting the phone, or changing devices, it cannot be reinstalled or reissued.
