Grab OTP Vietnam eSIM – Practical Guide for Travelers in 2025
When visiting Vietnam, many travelers rely on Grab for transport and food delivery.
But there is one catch: Grab requires an OTP (One-Time Password) via SMS to log in, confirm payments, or re-verify the app.
Without a local phone number, OTP often fails. In this article, we explain how Grab OTP Vietnam eSIM solves the problem,
using real cases, statistics, and practical tips to ensure your trip runs smoothly.

📲 Why OTP Matters in Vietnam
Grab uses SMS OTP for several functions:
- ✔ Account registration for new users
- ✔ Login on a new phone or after reinstalling the app
- ✔ Verifying GrabPay wallet or linking a payment card
Without OTP, you cannot complete these steps. International SIMs often fail because roaming SMS may not be supported or may incur high fees.
🌍 Common Traveler Problems with Grab OTP
In online expat forums, travelers frequently report issues like:
- ✘ Roaming SMS delayed or never delivered
- ✘ Data-only eSIMs cannot receive SMS at all
- ✘ Grab blocks VoIP numbers such as Google Voice or Skype
Example: a traveler from France tried to use Grab with his Orange SIM while roaming. The OTP cost €0.75 per message,
and one verification SMS took more than 20 minutes to arrive—making the service unusable.
