What is Vietnam Unlimited eSIM for tourists?
I just finished my trip and loved how convenient eSIM Vietnam Unlimited is when I travel Vietnam. It’s a built-in digital SIM that lets you use unlimited data without swapping physical cards.
My experience was incredibly smooth, a simple QR code scan was all it took to connect to the internet as soon as I landed.

Top 03 most used Vietnam Unlimited eSIMs
After my recent trip across Vietnam, I found that eSIM Unlimited is the key to a perfect journey. Essentially, this type of eSIM provides a huge amount of high-speed data every day and maintains a continuous connection at a regular speed (FUP) without worrying about losing connection midway.
#1. Viettel eSIM Vietnam Unlimited | 5 – 10GB/day ($7 – $30)
This is the strongest option in terms of coverage, reaching 99% of Vietnam’s territory. In my experience, Viettel’s network speed is the highest and most stable, even when I travel in mountainous areas in the North like Sapa, Ha Giang, making it a top choice for anyone looking for a Vietnam eSIM unlimited solution.
Or even to remote islands like Phu Quoc. This package is extremely suitable for those who travel for extended periods and move through many different provinces and cities.
Regarding pricing for international travelers on eSIM travel platforms, typical packages range from $7 to $30 depending on the validity period 7 to 30 days. If you need more intensive Unlimited FUP packages, the price may be higher, approximately $25 – $60.
During my recent trip, I chose this package $11 for 10 days. Easy to use. I ordered it online, then simply went to the mobile settings on my phone, scanned the QR code sent via email, and the network activated immediately. It was incredibly fast and there were no dead spots in the signal throughout the journey.
#2. Vinaphone eSIM Vietnam Unlimited | From 2 – 6GB/day ($9 – $15)
Vinaphone boasts incredibly impressive internet speeds in urban areas, making it ideal for video streaming and other entertainment needs. My actual measured speeds in the city ranged from 40–80 Mbps, ensuring smooth performance for all entertainment activities.
This network provider offers flexible Vinaphone eSIM Vietnam plans 7 days costs about $9–$12, 10 days about $11–$15, and longer packages like 15–30 days range from $13 to $31.
While in Hanoi, I bought the package 5GB/day at a price of approximately $13 for 10 days via Govnsim. After using up the 5GB of high-speed data for the day, the network switches to a lower-speed unlimited mode, but it’s still enough for me to check maps or send WhatsApp messages.
The setup was also done via a simple QR code, allowing me to have internet access as soon as I landed at the airport so I could book a ride to the hotel without having to queue to buy a physical SIM card, no question marks about connectivity at all.
#3. Mobifone unlimited data | From 1 – 8GB/day ($8 – $12)
If you need a balanced option between price and quality for your basic needs, Mobifone is a name worth considering. Internet speeds in the city are quite stable, reaching around 50–90 Mbps.
Their packages offer a variety of durations: 7 days price from $8 – $10, package 10 days about $9 – $12, and packages 15 – 30 days priced around $13 – $20.
My personal experience using the Mobifone unlimited data package was 4GB/day at around $11 for 10 days. I’m very satisfied with my experience in Da Nang. I ordered my SIM card from Vietnamesim and activated it via QR code in just a few minutes.
A major plus is strong hotspot support, making it easy to share with my work computer. While coverage is weaker than Viettel in remote areas, Mobifone is still a budget-friendly choice for tourist spots and a solid Vietnam eSIM unlimited option.

05 Notes when buying Vietnam Unlimited eSIM
To ensure your trip goes smoothly, choosing the right eSIM isn’t enough, you also need to know a few “tips” to avoid wasting money. Below are 5 important points I’ve learned from my personal experience in Vietnam:
- Check for compatibility: before buying, you need to make sure your phone supports eSIM and is an international version (not network locked) to avoid wasting money.
- Understanding high speed limits: most unlimited data plans are actually high-speed data limits per day, after which the network switches to a standard speed (FUP) so you can still text or view maps.
- Activation time: the usage period usually starts counting as soon as you scan the QR code, so you should set it up right before your flight or immediately after landing to optimize the number of days you use it.
- Choose your path: prioritize Viettel if you’re traveling to remote mountainous areas, but if you’re only staying in major cities, Vinaphone or Mobifone are more economical choices.
- Store QR codes: i always take a screenshot of the QR code and save the seller’s support information for quick troubleshooting if I accidentally delete the eSIM or encounter connection problems.
Conclusion
eSIM Vietnam unlimited is the top choice for enjoying your trip to the fullest without worrying about losing connectivity or wasting time switching physical SIM cards. Depending on your travel route, choose Viettel for remote areas or Vinaphone and Mobifone to optimize costs in major cities.
