No, the internet is open! This is a common misconception. Unlike China, Vietnam does not have the "Great Firewall." You can freely access Google, Facebook, Instagram, WhatsApp, TikTok, and all your favorite apps without needing a VPN. Our eSIM gives you unrestricted, high-speed access to the open internet.
This specific plan is valid only within Vietnam. This is the most important question for backpackers. If you are on the "Banana Pancake Trail" and cross the border into Cambodia or Laos, your connection will stop. For a seamless multi-country journey, we highly recommend our Asia Regional eSIM, which covers Vietnam, Cambodia, Thailand, and Laos with one single plan.
Yes, but it varies. You will have excellent 4G/LTE coverage in all cities (Hanoi, Ho Chi Minh, Da Nang) and towns. On Ha Long Bay cruises, the signal is strong when near the coast but can be intermittent or slow when sailing deep into the limestone karsts. For mountainous areas like Sapa and the Ha Giang Loop, you will have a good signal in the towns but should expect dead zones while driving on remote mountain passes.
To give you the best coverage in this long, thin country, our eSIM connects to the top-tier providers, typically Viettel or Vinaphone. Viettel is widely considered the best network (like the military's network) with the most extensive coverage, especially in rural and mountainous areas, ensuring you stay connected where other networks fail.
Yes, absolutely. Grab is the essential "super-app" in Vietnam for booking ride-hailing (cars and motorbikes) and food delivery. Our eSIM provides fast, low-latency data, which is crucial for ordering a Grab from the airport (Hanoi - NOI or Ho Chi Minh - SGN), tracking your driver in real-time, and using Google Maps to navigate the chaotic streets.
Most modern phones do, but you must check our specific list here: eSIM Compatible Devices to be 100% sure before purchasing.
You will have 4G signal for most of the coastal journey between Hanoi and Ho Chi Minh City, but expect the connection to drop in tunnels or remote sections near the Hai Van Pass.
Yes. Coverage is strong in Can Tho and on the water at the Cai Rang Floating Market, allowing you to share photos of the boat vendors instantly.
You will generally have signal at the visitor centers and entrances of Paradise Cave or Phong Nha Cave, but coverage is naturally lost once you go deep underground.
Yes. Coverage is excellent in the pedestrian-friendly Hoi An Ancient Town, which is essential for using translation apps with local tailors or finding the best banh mi spots.
