International visitors to Vietnam can now get a free MobiFone eSIM with 10GB of high-speed data, valid for 24 hours. You register online before you arrive using your passport and a portrait photo, receive a QR code for your eSIM, and then dial 900 after you land to activate it. This is an official connectivity service from MobiFone, one of Vietnam’s leading mobile operators, created so that international tourists can get online the moment they step off the plane — no physical SIM card, no queues, no language barrier at the airport.
For travellers coming from India, this is one of the easiest ways to stay connected in Vietnam without paying expensive international roaming charges. Below is a simple, step-by-step guide to claiming your free MobiFone eSIM in Vietnam, plus what to use once the 24 hours are over.
What Is the Free MobiFone eSIM in Vietnam?
The free MobiFone eSIM is a complimentary travel data package for international tourists: 10GB of high-speed data that stays valid for 24 hours once activated, limited to one eSIM per passport. An eSIM is a digital SIM built into your phone, so there is nothing physical to insert — you simply install it from a QR code and switch it on.
Because the MobiFone eSIM is delivered digitally, you can set everything up before your flight and arrive in Vietnam already prepared to connect. The 10GB allowance is enough for maps, ride-hailing apps, messaging, hotel check-ins, and sharing photos during your first day in the country.
The offer reaches travellers through more than one channel. Many visitors receive the registration link in the approval email for their Vietnam e-visa, and MobiFone has also run the same 10GB offer with partners such as Vinpearl and VinWonders. Each passport can claim the free eSIM only once, so if you already received it with your e-visa email, you cannot claim it again through a partner promotion.
Why Free MobiFone eSIM in Vietnam Is Useful for Indian Travellers
The free MobiFone eSIM lets Indian travellers use maps, Grab and WhatsApp the moment they clear immigration, without paying roaming charges or queuing at an airport SIM counter. For Indian tourists, getting online quickly after landing is usually the first hurdle of any trip, and the free eSIM removes it. Instead of searching for a SIM counter at the airport, comparing tourist packages, or waiting for activation, you arrive with data ready to go.
This means you can open Google Maps, book a Grab ride, message family back home, or pull up your hotel booking the minute you clear immigration. It is especially useful at the busiest arrival points, Noi Bai in Hanoi and Tan Son Nhat in Ho Chi Minh City; our guide to the international airports in vietnam explains which one your flight from India is likely to land at and how to get into the city.
Once you are online, booking your first ride is simple. Our guide to transportation in vietnam compares Grab, taxis, metro lines and private cars, so you know what a fair fare looks like before you leave the arrivals hall.
How to Get the Free eSIM: Step by Step
Claiming your free MobiFone eSIM takes three steps: register online with your passport, install the eSIM from the QR code, and dial 900 after you land in Vietnam. The first two are done before you travel, and the last one is done after you arrive.
Step 1: Register Before You Arrive
Before your trip, scan the QR code provided by MobiFone, or open the link in your e-visa approval email, to reach the registration website. On the website, upload a photo of your passport and a portrait photo of yourself for identity verification. This verification step is required by Vietnamese regulations, so make sure your passport image is clear and readable and that the details match your visa. If you have not applied yet, our guide to the vietnam visa for indian passport holders walks through the e-visa application step by step.
Step 2: Receive Your eSIM
After your registration is successful, you will receive a QR code for your MobiFone eSIM on screen and by email, along with the free package — 10GB of data valid for 24 hours. Install the eSIM on your phone by following the on-screen instructions, ideally while you are still at home on Wi-Fi. At this point, the eSIM is installed on your device but is not yet active. Your free data allowance has not started counting down, so there is no rush to activate it before you reach Vietnam.
Step 3: Activate on Arrival
Once you land at the airport in Vietnam, simply dial 900 from your MobiFone eSIM to activate the free package; the call is free. Your 24-hour countdown begins only after this activation call — not when you register and not when you install the eSIM. This is an important detail: activate the eSIM only when you are ready to start using your data, so you get the full 24 hours during your time in Vietnam. Turn on data roaming for the MobiFone line in your phone settings if the data does not start straight away.
Need More Data?
When the free 24 hours end, you can buy a MobiFone top-up with a Visa or Mastercard card, or switch to a longer tourist SIM or eSIM for the rest of the trip. MobiFone’s paid packages do not need a Vietnamese bank account or local cash. For current top-up options and prices, check the official MobiFone website.
Most Indian travellers spend 7 to 10 days in Vietnam, so a full-trip data plan is the better buy after day one. Our guide to the best vietnam esim for indians compares Viettel, Vinaphone and MobiFone tourist packages by data, validity and price, and shows where to buy each one.
Important Notes for Indian Travellers
A few things are worth knowing before you rely on the free MobiFone eSIM.
First, your phone must support eSIM and be unlocked. Many phones sold in India are carrier-locked or do not have eSIM capability, so check your device before you travel. Most recent iPhones and many newer Android models support eSIM, but it is always worth confirming.
Second, keep your Indian SIM active alongside the eSIM. Bank OTPs and verification codes from India are usually sent to your home number, so you will want to keep receiving SMS on your primary SIM while using the MobiFone eSIM for data.
Third, plan for coverage. MobiFone offers strong coverage across major cities and popular tourist areas. However, signal can be weaker in remote mountainous regions and rural areas, so if your itinerary includes places like Sapa, factor this in and do not depend on a single network for the whole trip.
Finally, remember that the free package lasts only 24 hours and the offer depends on MobiFone’s current campaign. It is meant as a convenient first-day connection, not a full-trip data plan, so check that the registration page is still open before you fly and arrange a top-up if you are staying longer.
