Does Grab work in Vietnam?
Yes — works normally
Yes. Grab works normally in Vietnam over mobile data — there is no China-style block. Just get online with a Vietnam eSIM and open the app as usual.
Detail: The main ride & food app in Vietnam. Sign-up and driver call-backs need a phone number that can receive SMS/calls.
Heads up: Grab needs a Vietnamese phone number to receive the sign-in code (OTP). Our Vinaphone eSIM includes a real +84 number that receives SMS and calls; Viettel and Skyfi are data-only.
Using Grab on a Vietnam eSIM
Install a Vietnam eSIM before you fly, set it as your data line on arrival, and open Grab as normal. 5GB/day easily covers messaging, maps and video calls.
