📑 What Is FUP and Why It Matters

Fair Use Policy (FUP) is a hidden limit used by most providers. They allow high-speed data up to a threshold (e.g., 2–5GB per day), then throttle speeds once you exceed it. For travelers relying on maps, Grab, or video calls, FUP can turn “unlimited” into frustration. Understanding unlimited pocket wifi vietnam fup helps avoid costly surprises.

⚙️ How “Unlimited” Pocket WiFi Works in Vietnam

• Daily allowance: Most routers include 2–5GB/day at 4G or 5G speed.
• Throttle speeds: After that, speeds drop to 128kbps–512kbps — too slow for video calls or streaming.
• Reset cycle: High-speed data resets every 24 hours.

Providers use “unlimited” to attract customers, but the fine print usually reveals strict FUP caps.

💸 Cost vs FUP: What Travelers Actually Pay

In practice, prepaid eSIMs provide equal or more daily data at 20–30% lower cost, without deposits or throttling surprises.

🧭 Traveler Story: Conference in Ho Chi Minh City

David, a consultant from the US, rented a Pocket WiFi with “unlimited data” at Tan Son Nhat Airport for US$6/day. During his first day, he streamed a webinar and quickly exceeded the 3GB/day limit. Speeds dropped, making his video calls almost impossible. The next day, he switched to a prepaid eSIM (~US$18.50 for 30 days, 6GB/day) and had stable connections throughout his stay.

🧭 Traveler Story: Backpacking in Ha Giang

Linda from Taiwan used a Pocket WiFi on her rural motorbike loop. The router capped her at 2GB/day before speeds slowed dramatically. Her friend used a Viettel-based prepaid eSIM (5GB/day) with no noticeable throttling. In rural areas, carrier choice and daily limits mattered more than “unlimited” marketing claims.
