# Does It Work in Vietnam? (2026-11-11)

Vietnam relies heavily on Viettel for rural 4G/5G coverage and Grab for urban transport, while third-party airport SIM kiosks frequently sell unverified SIMs that deactivate mid-trip.

> **Quick take:** Choose a travel eSIM that roams on Viettel (Airalo Xin Chao or Nomad) rather than Vietnamobile, and link your foreign card in the Grab app before leaving home.

## Service Compatibility Matrix

- **Vietnam eSIMs, Grab & Foreign Card Payments** [conditional]: eSIMs backed by Viettel or Vinaphone work nationwide; cheap airport SIMs on Vietnamobile lose signal outside Hanoi/HCMC or get deactivated after 3 days due to stricter subscriber ID checks.

- **Grab & Be Ride-Hailing** [works]: Grab accepts foreign Visa, Mastercard, and Wise cards seamlessly; avoids taxi meter scams at Noi Bai (HAN) and Tan Son Nhat (SGN) airports.
- **Zero-Fee ATM Withdrawals (VPBank & TPBank)** [works]: VPBank and TPBank ATMs charge 0 VND local ATM operator fees for foreign Wise and Revolut debit cards.
