Does It Work InDoes It Work in Vietnam?
Southeast Asia · Last verified 2026-11-11Vietnam 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.
Pre-departure takeaway: 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)
| Service / App | Status | On-the-ground reality & rules |
|---|---|---|
| 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. Read guide → |
| 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. |
