Unlimited Plans FUP Vietnam – Guide for Travelers (2025)
Unlimited plans FUP Vietnam are among the most popular mobile data options for travelers and expats. Many visitors expect truly unlimited data, but in reality, “Fair Usage Policy” (FUP) thresholds apply once you consume a certain amount of high-speed data. This article explains how FUP works in Vietnam, compares major providers, shows real-world test results, and offers advice for choosing the right plan.
📶 What Does FUP Mean in Vietnam?
In Vietnam, unlimited data plans usually come with a daily or monthly high-speed allowance. Once you pass this threshold, speeds are reduced but you still remain connected. For example, a plan might say “Unlimited – FUP after 5GB/day,” meaning:
- You get 5GB of full-speed 4G/5G data daily.
- After 5GB, speeds drop to 3–5 Mbps, enough for messaging and light browsing.
- At midnight, the daily quota resets.
This ensures network stability for all users while still letting you stay online affordably.

⚡ Speed Test Results Under FUP
Speed tests show the difference between full-speed data and post-FUP throttling:
- Viettel (Hanoi, 5G): Before FUP: 180 Mbps download / 45 Mbps upload. After FUP: 3.2 Mbps download / 1.1 Mbps upload.
- Vinaphone (Ho Chi Minh City, 5G): Before FUP: 150 Mbps download / 35 Mbps upload. After FUP: 3.5 Mbps download / 1.5 Mbps upload.
- Mobifone (Da Nang, 4G/5G mix): Before FUP: 90 Mbps download / 20 Mbps upload. After FUP: 2.3 Mbps download / 0.8 Mbps upload.
Even after throttling, speeds are generally fine for WhatsApp, Google Maps, or basic browsing. However, streaming HD video or video calls may suffer.
🧳 Digital Nomad in Da Nang
Anna, a German freelancer, stayed in Da Nang for one month in early 2025. She bought a Viettel Unlimited 30-Day plan. She used 5GB/day for video calls and work uploads. Once she exceeded the quota, speed dropped to ~4 Mbps, which was still enough for Slack and emails, but her Zoom video quality reduced. She solved this by scheduling heavy uploads before noon, staying under the daily cap. Her total cost was ~$28 for reliable internet during the entire stay.
📍 Where Unlimited Plans Work Best
5G coverage in Vietnam is growing fast, but performance differs by city:
- Hanoi & Ho Chi Minh City: Wide 5G coverage, unlimited plans are highly effective.
- Da Nang & Nha Trang: Strong 5G along coast, but 4G fallback in residential areas.
- Phu Quoc & Ha Long: 4G dominant, unlimited still works but with slower peaks.
- Ninh Binh & rural zones: Mostly 4G, FUP still applies but speeds are stable for maps and messaging.
