Getting Connected in Vietnam: A Practical Review of the Viettel 10-Day 5GB/Day SIM
When you land in Hanoi, having a reliable internet connection is about as essential as your passport. The Viettel 10-Day 5GB daily data SIM—available as both eSIM and physical SIM—offers a straightforward way to stay online without the fuss. Priced at just under $8 per person, this SIM provides high-speed 4G LTE/5G across Vietnam, making it perfect for travelers who want to navigate, share, and explore without worrying about roaming charges. The process begins right at Noi Bai International Airport, where professional staff set you up quickly—no long waits, no hidden fees.
What we especially appreciate is how simple and transparent the experience is—full compliance with Vietnamese regulations means no surprises. Plus, the 24/7 multilingual support is a comfort if you run into any hiccups. The second highlight? The versatility of options—whether you prefer a physical SIM or the convenience of an eSIM, both are included and compatible with all unlocked smartphones. That’s a real plus for travelers with different devices.
A potential consideration? This package is data-only, so if you need to make calls or send SMS, you’ll need to use your own plan or apps. Still, for most travelers focused on navigation, social media, and quick communication, this isn’t a dealbreaker.
This SIM is ideal for independent travelers, digital nomads, or anyone wanting reliable, affordable connectivity from the moment they land—especially if you value simplicity, speed, and good customer support.

The Essentials: What’s Included and How It Works
This package provides a 10-day validity period with 5GB of data per day—a generous amount for most travelers. It’s designed purely for data, so if you’re looking to make calls or send texts, you might need to use messaging apps like WhatsApp or Viber, which utilize data instead of traditional voice lines.

The Pickup Experience at Noi Bai Airport
One of the standout advantages is how convenient and straightforward the pickup process is. Arriving travelers have praised the professionalism of staff like “helped and happy” service providers—no long lines, no confusing instructions. Just walk up to the airport counter, where setup is fast and fully compliant with Vietnamese regulations. The full transparency on fees and process means you won’t be surprised by hidden charges.

Cost-Value Analysis
At $7.93 per person for 10 days, this SIM offers excellent value, especially considering the convenience, speed, and nationwide coverage.
