Vietnam eSIM Unlimited Data – Is It the Best Choice for Tourists?
📱 Curious about Vietnam eSIM unlimited data for your trip in 2025? This guide covers what “unlimited” really means, compares real plans, speed, and limitations, plus tips for choosing the best option for tourists. Data and examples are all verified (July 2025) – no hype, just facts!
🌏 What Does “Unlimited Data” Mean for Vietnam eSIM?
- 🚀 Unlimited ≠ Uncapped: Most Vietnam eSIMs offer unlimited data with a fair-use (FUP) speed limit. For example, “5GB/day high-speed, then unlimited at 128kbps” (Viettel/Mobifone plans via GoVnSIM, July 2025).
- 📉 After daily limit: Your speed drops from 4G/LTE (30–90 Mbps) to ~128–256 kbps (enough for chat/WhatsApp but not video).
- 🔄 Reset daily: The high-speed quota resets every 24 hours (not total for the month).
- 📝 Data-only eSIMs: Some “unlimited” plans are data-only and don’t offer a phone number or SMS/OTP for Grab, Zalo, etc.
Case Study: Alex (UK, 12 days in Vietnam): Used Viettel eSIM 5GB/day unlimited. After hitting 5GB, speed dropped but WhatsApp and Maps still worked. Needed high-speed for YouTube, so used WiFi in evenings.
🛒
| Provider | Plan | High-Speed Data | Unlimited Data | Phone Number | Validity | Price (USD) |
|---|---|---|---|---|---|---|
| Viettel (GoVnSIM) | eSIM 30-Day | 5GB/day | Yes (128kbps after 5GB) | +84 included | 30 days | $18.5 |
| Mobifone (GoVnSIM) | eSIM 30-Day | 6GB/day | Yes (128kbps after 6GB) | +84 included | 30 days | $14.5 |
| Vinaphone | eSIM 30-Day | 2GB/day | Yes (128kbps after 2GB) | +84 (check availability) | 30 days | $17–22 |

💡 Who Should Choose an Unlimited Data eSIM for Vietnam?
- 🏄♂️ Great for: Tourists who use lots of maps, ride-hailing, social media, email, but don’t need constant HD video streaming.
- 🛫 Ideal for: Digital nomads on short trips, expats who want daily reset, travelers with multiple destinations.
- 🎬 Not for: Users who need unlimited HD streaming or huge daily uploads (YouTubers, streamers) – use hotel WiFi for heavy tasks.
Example: A tourist with average use (navigation, calls, Instagram, a few YouTube videos) rarely exceeds 5GB/day high-speed.

- 📈 High-Speed Data (4G/LTE): Most tourists get 30–90 Mbps download in big cities (Hanoi, HCMC, Da Nang), checked with Speedtest July 2025.
- 🏖️ Coastal/remote areas: Expect 10–40 Mbps in places like Nha Trang, Phu Quoc, Sapa (Viettel is best for rural/mountain).
- 🔄 After daily quota: Speed drops to 128–256 kbps (text/chat only, slow for video/browsing) until midnight reset.
- 📶 5G available: In parts of Hanoi and HCMC with some new devices (Mobifone/Viettel eSIM, not guaranteed everywhere).
- 🌏 Network Coverage: Viettel & Mobifone cover 99% of Vietnam’s population, including most rural and tourist sites.
Tip: Use public WiFi at hotels/cafes for heavy tasks after daily FUP, but don’t rely on free WiFi for privacy or reliability.
🧳 Case Study: Using Unlimited eSIM Data as a Vietnam Tourist (2025)
Case: Emma & Leo (Singapore) traveled 10 days from Hanoi to Phu Quoc using Viettel eSIM (5GB/day “unlimited”). Both worked remotely (video calls, Google Maps, IG, Grab, Zalo).
Real experience: “Never hit the daily FUP limit except for 2 days with heavy streaming. Data always reset at midnight. Grab, Zalo, OTPs all worked with local number. In Sapa, still had 4G for maps & messages!”
Summary: High-speed was enough for all typical tourist needs, even in remote areas.
