• Activation: Scan a QR code, install the profile, and you’re online in minutes.

Important: As of 2025, Viettel and MobiFone are the leading networks that reliably issue eSIMs with a Vietnamese number to international travelers. VinaPhone offers limited options and not all sellers can provide a working local number.
