See top eSIM providers in Vietnam and choose the right plan for yourself!
When traveling to Vietnam, choosing an eSIM can simplify your connectivity. Here's why it's the ideal solution:
Vietnam offers expanding 4G networks and growing 5G coverage in major cities, with reliable service in urban hubs like Hanoi, Ho Chi Minh City, and Da Nang. Free public Wi-Fi is common in cafes, hotels, and tourist areas, but speeds and security can be inconsistent.
Having your own mobile data ensures seamless access to Vietnam’s vibrant culture — from ancient pagodas to bustling street markets and hidden gems like egg coffee or motorbike culture. Stay connected for live translations, ride-hailing apps like Grab, and up-to-date travel tips on the go.
Choose your data plan based on your travel style:
Vietnam’s mobile networks are rapidly modernizing, but selecting the right eSIM requires balancing affordability, coverage, and practicality. Here’s what to prioritize for a stress-free experience:
Vietnam’s 4G coverage is strong in cities like Hanoi, Ho Chi Minh City, and Da Nang, but speeds drop in rural areas (e.g., Ha Giang’s mountains, Mekong Delta villages).
Some islands (Phu Quoc, Con Dao) or remote regions may have patchy service. Check if your eSIM provider partners with local giants like Viettel, Mobifone, or Vinaphone — they dominate rural coverage.
Many budget Android phones sold in Vietnam lack eSIM support. Double-check your device’s specs (e.g., iPhone XS/newer, Pixel 3+/Galaxy S20+). Travelers with older or locally purchased devices may need a physical SIM instead.
Few local providers offer English-language support. Choose eSIM brands with 24/7 chat/email assistance (e.g., Holafly, Airalo, or regional services like Gigago). For local SIMs, download translation apps like Google Translate for store interactions.
Avoid providers requiring in-person registration (common with local carriers). Opt for eSIMs that activate via QR code or app. The best thing you can do is to buy and activate your eSIM before arriving — airport kiosks and street vendors often overcharge tourists.

Airalo offers a convenient alternative to traditional SIM cards, removing the need to visit stores, which is especially if you’re arriving in busy cities like Hanoi or Ho Chi Minh City. Thanks to its partnerships with Vietnam’s largest telecom providers, Airalo ensures reliable 4G/LTE coverage in urban areas.
For city travelers, Airalo provides fast internet speeds perfect for everyday use like navigation, social media, and messaging apps. While it works great in major cities, performance can be less dependable in more remote areas, such as Ha Giang’s mountains or the villages in the Mekong Delta.
For example, heavy data users who stream HD videos or need a constant, high-speed connection may find Airalo’s lack of unlimited plans limiting. Its pay-as-you-go data plans are ideal for light to moderate users but may fall short for those who need high-speed access in off-the-beaten-path locations.
Despite these challenges, Airalo’s app is easy to use and activates instantly. Some users have reported delays in rural network switching and processing refunds, but the company offers multilingual support through email and chat, though response times can be slower during busy times.

Though aloSIM offers solid coverage in major cities across Vietnam, users may experience slower speeds or less reliable service in more remote areas like Ha Giang or the Mekong Delta. However, for tourists in bustling cities, aloSIM’s data plans are more than sufficient for navigation and social media use.
One standout feature is aloSIM’s offer of a Hushed international number, which can be helpful for travelers who need a temporary number for registration or verification purposes during their stay. However, like most eSIMs, aloSIM is data-only, meaning no voice calls or SMS capabilities.
