How Many Times Can Viettel eSIM QR Code Be Used: Policy for 2025

 

In 2025, Viettel has reinforced a strict one-time-use policy for tourist eSIM QR codes to ensure secure and hassle-free connectivity for international travelers. Each QR code acts as a unique activation key that can be scanned only once, linking the eSIM profile permanently to the device used during the first installation. After activation, the QR code becomes invalid and cannot be reused under any circumstances — not even on the same device after a factory reset, software update, data wipe, or accidental deletion of the eSIM profile.

If travelers switch to a new phone, lose the physical QR code, or mistakenly remove the installed eSIM, Viettel requires them to obtain a completely new eSIM. Replacement options are readily available at Viettel service counters located in major international airports across Vietnam, as well as at official Viettel stores nationwide. While the original tourist eSIM cannot be reissued or re-downloaded, staff at Viettel stores can instead provide a domestic Viettel eSIM that offers reliable coverage, stable data speeds, and full service functionality suitable for short-term visitors.

This one-time QR code policy is designed not only to protect user identity and phone number security but also to maintain the integrity of Viettel’s activation system. By preventing the reuse or duplication of eSIM QR codes, Viettel ensures that customers experience a safer, more stable, and more transparent mobile service throughout their stay in Vietnam.
