How much is a SIM card with unlimited data in Vietnam cost? Prices range from 7 AUD to 18 AUD, and Viettel, Vinaphone, or eSIM are the best options for tourists.
Unlimited data SIM cards are popular in Vietnam, especially with tourists and young people, due to low cost and wide coverage. Most operators offer daily high-speed “unlimited” packages for travel and entertainment.
What is an unlimited data Vietnamese SIM card?
While researching and using unlimited data Vietnamese SIM cards during my trip, I realized the concept of “unlimited” can be easily misleading, here are some travel Vietnam tips to help you choose the right SIM.
In reality, the SIM only has a daily high-speed data limit; after that, the network is still usable but at reduced speed or with temporary disconnection, not unlimited high-speed data. The important point is that there are no extra charges, even when I use it heavily for maps and social media.
Regarding where to buy, I found the most convenient way is to purchase directly at the international airport, or at official Viettel, Vinaphone, or Mobifone stores in the city.
Alternatively, I can also order an eSIM online before my trip and use it immediately upon landing, which is very convenient if I don’t want to waste time buying a SIM in Vietnam.
Vietnam sim card unlimited data price
During my travels throughout Vietnam, I found the price of unlimited data Vietnamese SIM cards to be very reasonable and accessible, especially compared to many other countries. The fees weren’t too high, yet they were sufficient for daily use of Google Maps, YouTube, social media, and video calls without incurring extra costs.
Most “unlimited” SIM packages offer a daily high-speed data allowance before the speed is reduced, and in practice, Viettel, Vinaphone, or international eSIMs provide stable connections — perfect for travelers wondering how much is a SIM card in Vietnam.

Top 05 best unlimited data Vietnamese SIM cards
During my recent trip to Vietnam, I tried many Vietnam SIM card unlimited data options to find the best for browsing, watching videos, checking maps, and staying in touch. Here are the top choices for speed, stability, and price, all great for foreigners.
#1. Viettel Tourist SIM – Widest coverage, stable everywhere
Viettel Tourist SIM was my first choice when I came to Vietnam because Viettel has the strongest coverage, even in areas far from the city, such as mountainous or plateau regions.
Packages typically provide approximately 5–10 GB of high-speed data per day, and you can still access the internet at a lower speed after reaching the limit.
The price is usually around AUD 8–14 (120,000–250,000 VND) for 7–30 days. With this SIM, I can watch YouTube, use Google Maps all day, and livestream on Instagram very smoothly.
#2. Vinaphone Tourist SIM – Suitable for using social media and city maps
Vinaphone Tourist SIM is a great choice if you mainly stay in large cities or popular tourist areas. The packages usually include 6–15 GB of high-speed data for 15–30 days, priced at around AUD 9–11 (150,000–200,000 VND).
When I used this SIM card in Hanoi and Ho Chi Minh City, the speed was very good for uploading photos, watching 1080p videos, and searching for destinations using Google Maps.
#3. Mobifone Tourist SIM – Suitable for budget-friendly travel
Mobifone Tourist SIM is suitable for travelers who want to save money but still have stable internet for basic needs. Popular packages usually offer around 4 GB of data per day at a price of approximately AUD 7–10 (120,000–200,000 VND) and often include a few minutes of local calls.
#4. Vietnamobile Data-Rich SIM – Affordable and budget-friendly
Vietnamobile is the option I choose when I want to maximize savings while still having decent data, usually around 5–8 GB/day, at a lower price than major carriers (around 150,000 VND or AUD 7–9).
With this package, I can still access the internet, use WhatsApp, and watch short videos daily. However, when traveling far from city centers, coverage is not as strong as Viettel, and speeds may drop.
#5. Vietnam International eSIM – Suitable for purchasing before arrival
If I don’t want to switch to a physical SIM card when arriving at the airport, choosing a Vietnam SIM card unlimited data eSIM is very convenient. I previously bought a Viettel eSIM and activated it immediately upon arrival in Vietnam.
eSIM packages typically include 5 GB/day or a larger total data allowance depending on the number of days, priced at approximately AUD 10–20 (USD 8–15). eSIMs are suitable for city travel, organized tours, or dual-SIM users who don’t want to waste time at the destination.
05 Notes when buying a Vietnam travel SIM card
After researching and using various SIM cards in Vietnam, I found buying one isn’t hard, but choosing the wrong option can be frustrating due to slow speeds or hidden limits. Here are 5 practical question marks every traveler should know.
- Don’t mistake “unlimited data” for unlimited speed: Most travel SIM cards have a daily high-speed data limit (e.g., 4–10 GB/day). Once this limit is reached, the network still works but at reduced speed, which is enough for basic messaging or searching.
- Ask clearly whether hotspot sharing is allowed: Many SIM cards advertise unlimited data but restrict hotspot usage or limit the number of devices that can share the connection. If you plan to use the SIM as a hotspot for a laptop or other devices, check this in advance.
- Avoid buying SIM cards from unknown providers at the airport: Airport SIMs are often 10–30% more expensive and may not be official Viettel, Vinaphone, or Mobifone packages. If it’s not urgent, buying from official stores in the city is cheaper and more reliable.
- Choose your mobile carrier based on your travel route, not just price: If traveling across multiple provinces or rural areas, Viettel is the most stable. For city travel with heavy social media and map usage, Vinaphone is very suitable. For short trips and budget travel, Mobifone or Vietnamobile is sufficient.
- Carefully check SIM activation and expiration rules: Some SIMs start counting from activation, while others count from the purchase date. For eSIMs or SIMs bought online in advance, make sure the SIM only activates when you arrive in Vietnam to avoid wasting usage days. This is important when deciding which SIM is best for unlimited data
Conclusion
Vietnam’s unlimited data SIM cards help travelers stay connected conveniently and affordably. If you’re wondering how much is a SIM card with unlimited data, choosing the right provider based on your needs and travel itinerary will ensure a stable internet experience and a more enjoyable trip in Vietnam.
