A comprehensive guide to choosing the best eSIM in Hanoi. Compare updated 2025 prices, coverage insights, and traveler case studies to stay connected with ease.
📲 Why Choose an eSIM in Hanoi?
eSIMs have become the preferred choice for international travelers in Hanoi. Instead of queuing at kiosks in Noi Bai Airport or dealing with physical SIM swaps, you can activate an eSIM instantly with a QR code sent via email. This means you step off the plane and already have internet access for maps, ride-hailing apps, and hotel check-ins.
According to a 2024 VNAT survey, nearly 48% of tech-savvy visitors used an eSIM during their stay in Vietnam, and this number continues to grow in 2025 as more phones adopt eSIM-only slots.
