Realistic Openline speeds in Vietnam

  • 4G/LTE: 20-80 Mbps down in urban areas, 5-20 Mbps in suburban areas.
  • 5G: 100-500 Mbps down where deployed (major cities).
  • 3G fallback: 1-5 Mbps in rural areas where 4G isn't deployed.

Factors that affect your speed

  • Which partner you're attached to. Try manual network selection if speeds are slow.
  • Congestion — busy areas at peak hours may be slower.
  • Signal strength — check bars; low signal = low speed.
  • Time of day — evenings are peak in most countries.

Country-specific note

Hanoi, Ho Chi Minh, Da Nang strong. Some throttling of international services.

To check your current speed

Use Speedtest.net or Fast.com from your Openline connection.
