Starting June 15, 2026, VinaPhone subscribers (including Nha Trang residents) must pass facial biometric verification when installing a SIM card in a new device. Failure to confirm identity within 2 hours will result in blocking of outgoing calls and SMS (incoming calls and internet remain active). After 60 days, the block becomes two-way, and after an additional 5 days, the number may be disconnected. Identity can be verified online via the My VNPT app or offline at a VinaPhone store (chip-based CCCD required). Free hotline: 1800 1091.
