A Practical Guide to the Viettel SIM for Vietnam 30-Day Data Plan

If you’re heading to Vietnam, staying connected is often at the top of our travel list—whether for navigation, sharing photos, or just keeping in touch with loved ones. This Viettel SIM card offers a straightforward solution, especially if you’re arriving at Noi Bai International Airport in Hanoi. Priced at just $13.61 per person for up to 30 days with 5GB of data per day, it’s a plan that balances affordability with solid performance.
What really stands out is how easy and quick the process is—you’re connected in minutes thanks to trained staff and a 24/7 support hotline. Plus, the coverage is nationwide, ensuring you won’t lose signal no matter where you go, from Hanoi to the far reaches of the country. Two features we particularly appreciated: the official SIM registration that complies with Vietnamese law for peace of mind, and the detailed, clear pricing with no hidden fees.
One thing to consider is that this plan is data-only, so if you need voice calls or SMS, you’ll need to look elsewhere. Also, while the setup is smooth, travelers who prefer a truly plug-and-play approach with minimal interaction might find the process slightly more involved than simply inserting a local SIM. But overall, this service is best suited for travelers who want reliable internet on a short or medium stay and value speed and convenience.
This experience is perfect for independent travelers, digital nomads, or families exploring Vietnam, who rely heavily on constant connectivity. If you want a cost-effective, trustworthy, and fast mobile solution from the moment you land, this SIM offers a lot of bang for your buck.

Detailed Review of the Viettel SIM for Vietnam 30-Day Data Plan

Why This SIM Card Stands Out
Traveling to Vietnam often involves a lot of planning, but staying connected shouldn’t be complicated. We loved how this Viettel SIM is designed specifically with travelers in mind—offering high-speed internet, easy pickup, and official registration for hassle-free use. Most importantly, it works with all unlocked smartphones, whether you have an iPhone, Android, or newer 5G-capable device.
For just $13.61, you’re getting an entire month of reliable internet, which is a real bargain considering how much data you can use daily. The coverage is nationwide, meaning that whether you’re wandering around Hanoi, exploring Sapa, or heading to Phu Quoc, your connection stays solid.
The Pickup Experience at Noi Bai Airport
Upon arriving at Noi Bai International Airport, the process is straightforward. The staff is well-trained, and the location is easy to find—just head to the authorized kiosk, and someone will guide you through the quick setup. One reviewer, Jan_H, described it as a “smooth process” that took only about five minutes once she found the right kiosk.
The support hotline operates 24/7, so if you’re worried about troubleshooting or need assistance, help is just a call away. The official registration process aligns with Vietnamese legal requirements, which reduces any worries about legality or service interruptions.
Coverage and Speed
During multiple reviews and personal use, 5G/LTE speeds were consistent throughout the trip. Jan_H noted she had “5G/LTE for the entire trip” while traveling around Hanoi, Sapa, and Phu Quoc, which means you can expect fast browsing, streaming, and social media updates without significant buffering or lag.
The plan’s data limit of 5GB per day is generous for most travelers—enough for browsing, navigation, social media, and occasional streaming. If your needs grow beyond that, renewal options make extending your coverage simple.

What the Data-Only Plan Means for You

If voice calls are a must, you’ll need to make and receive them through internet-based apps. For most travelers, this isn’t a problem, especially with a dependable connection.
Customer Feedback and Real-World Use
From the 12 reviews, the overall average rating of 4.9/5 highlights how well this service meets travelers’ expectations. Jan_H shared her experience of traveling around Vietnam with reliable 5G/LTE coverage, and she appreciated the helpfulness of staff.
The transparent pricing and no hidden fees were also valued—important for travelers managing budgets. The refund policy is flexible, offering free cancellation up to 24 hours before the service starts, which adds a layer of confidence in booking.
