How to choose for a multi-city 10-day route
Decide based on three simple factors: daily consumption, sharing needs, and travel pattern.
Daily consumption
- Light (maps, messaging, photos): 5–10GB total or 1GB/day plan is usually enough.
- Moderate (frequent navigation, social uploads, short videos): 10–20GB or unlimited if you don’t want to track usage.
- Heavy (working remotely, daily video calls, continuous uploads, streaming): choose unlimited to avoid throttling or top-ups.
Sharing and hotspot
All listed plans include unlimited hotspot. If you’ll tether a laptop or share with travel companions on buses/trains, pick unlimited to prevent unexpected slowdowns.
Moving between cities
Both Viettel and MobiFone cover major routes (Hanoi–Da Nang–Hoi An–Nha Trang–Ho Chi Minh). Unlimited gives peace of mind on long train or flight days when you rely on maps and mobile tickets.
Practical scenarios: which plan fits your trip?

| Backpacker, photo-heavy | Uploading photos to cloud each evening, social media stories | Unlimited 10-day ($24.99) — avoids running out during itinerary changes |
| Remote worker on the move | Video calls, VPN, large file transfers | Unlimited 10-day ($28.99–$29.99) — hotspot support for laptop, stable speeds |
| Family sharing one line | Maps, messaging, occasional streaming | Unlimited 10-day ($24.99) or 20GB ($41.99) if you prefer capped cost |
| Budget short-stay user | Light use, offline directions, occasional browsing | 10GB (1GB/day) $22.99 or 5GB $12.99 if you strictly limit streaming |
