eSIM Vietnam for Grab: The Ultimate Guide for Travelers (2025)
eSIM Vietnam for Grab is the smart solution for travelers who want instant access to ride-hailing and delivery services in Vietnam. In 2025, Grab remains the top app for getting around cities like Hanoi, Ho Chi Minh City, and Da Nang — but you’ll need a local phone number to sign up and use it. That’s where a Vietnam eSIM with a phone number makes your trip easy and stress-free!
Why You Need an eSIM Vietnam for Grab
Grab is Vietnam’s super-app, offering services such as car and bike rides, food delivery, grocery shopping, and even mobile payments. However, to register for a Grab account, you must have a local Vietnamese phone number to receive SMS codes for verification and for ongoing communications with drivers and couriers.
Here’s why a physical SIM card is no longer the best choice:
- Time-consuming: Buying a SIM card at the airport or a shop can take up to 30–60 minutes, often with passport checks and activation delays.
- Lost opportunity: Without instant connectivity, you might struggle to get a ride or order food upon arrival.
- Phone compatibility: Many modern phones now use eSIM for convenience, making it easier to keep your home SIM active too.
What is an eSIM and How Does It Work in Vietnam?
An eSIM (embedded SIM) is a digital SIM that you install directly to your phone. With a Vietnam eSIM, you can get a local number, call, text, and use data — all without waiting in line or swapping out your main SIM card. The process is entirely online: you simply scan a QR code to activate your plan, which is perfect for busy travelers.
Benefits of Using eSIM Vietnam for Grab
- Instant Grab Registration: Sign up for Grab as soon as you land, without searching for a SIM card shop.
- Seamless App Experience: Receive verification codes and driver updates without delays.
- Convenient Food & Delivery Orders: Order food and packages using your Vietnamese phone number — no hassles!
- Switch Back to Home SIM Anytime: Keep your primary SIM active for banking/OTP while using your eSIM for Grab and local calls.
- Ideal for Both Tourists and Expats: Whether you’re staying days or months, you have flexible options.
Can I Use Grab in Vietnam Without a Local Phone Number?
It’s technically possible to use Grab with some foreign phone numbers, but it’s unreliable. Most drivers expect a Vietnamese number for calls and SMS. For full access to GrabBike, GrabCar, and especially GrabFood or GrabExpress, a local phone number is required. An eSIM with a phone number is the most efficient, hassle-free way to unlock every Grab service.

- Place your order online before departure, or from your hotel upon arrival.
- Receive your eSIM QR code via email within minutes (no physical delivery required).
- Scan the QR code on your smartphone (see full activation guide here).

Is eSIM Accepted on All Phones in Vietnam?
Most modern smartphones support eSIM: iPhones (XS, XR, 11 and newer), Samsung Galaxy (S20 and newer), Google Pixel (Pixel 3 and newer), and other flagship devices. Always double-check your device’s compatibility before purchasing. For a full list, see this [official GSMA resource](https://www.gsma.com/esim/devices/).
Why Travelers Shouldn’t Use Data-Only eSIMs for Grab
Some eSIMs only provide data, not a real Vietnamese number. Grab requires a working local number for sign-up, ride updates, and driver communications. If you use a data-only eSIM, you’ll face verification issues and potential service interruptions. Always choose a Vietnam eSIM with a phone number for the smoothest Grab experience.

How to Fix Grab OTP Issues with eSIM Vietnam
Even with the right eSIM Vietnam for Grab, some users experience trouble receiving OTP (One-Time Password) codes during registration or app login. Here’s how to make sure you never get stuck:
- Double-check your phone number: Always copy-paste the exact Vietnamese number issued by your eSIM provider. Avoid country code mistakes (Vietnam: +84).
- Test SMS before registering: After activating your eSIM, send yourself a test SMS using another app or ask your provider to confirm SMS works.
- Switch off WiFi temporarily: Sometimes WiFi calling or certain VPNs may block SMS; switch to mobile data to receive Grab’s OTP smoothly.
- Check for signal: In some airports or buildings, signal may be weak. Move outdoors if needed during OTP step.
- Use the Grab web version: Occasionally, registering via the Grab website on your browser may solve rare app bugs with OTP codes. Try the Grab web version here.
- Contact your eSIM provider: Good providers (like GoVnSIM) have responsive support to assist if you miss an SMS or have technical problems.
Expert Tips for Using eSIM with Grab in Vietnam
- Save Your Phone Number in Contacts: This avoids copy-paste mistakes and makes it easier to share your number with drivers if needed.
- Set Up Dual SIM Correctly: On iPhone/Android, assign your eSIM as the main line for Grab and data; your home SIM remains active for banking/OTP.
- Keep SIM Profiles Separate: Label your eSIM “Vietnam Local” to prevent confusion in your phone’s SIM settings.
- Enable Push Notifications: Let the Grab app send you real-time updates on driver status, order arrival, and more.
- Top-Up (if needed): Some plans come prepaid, others require topping up for calls/SMS — check your eSIM’s balance and top up online.
