3. What Does “Unlimited” Mean? Details on Fair Use and Throttling

While unlimited sounds like infinite data, most providers implement a fair use policy to prevent network abuse. This means after a certain data threshold (usually between 5GB to 20GB), speeds may be reduced or throttled during peak times.

However, this throttling rarely impacts everyday browsing or streaming significantly.

Understanding these limits helps you choose the right plan based on your expected usage. For example:

• Heavy video streaming might require a higher fair use limit.
• Casual browsing and messaging can work well with moderate fair use thresholds.

4.2 Speed Test Results

Independent tests show that users enjoy average download speeds ranging from 50 Mbps on 4G to over 200 Mbps on 5G networks in central areas like Victoria Harbour and Causeway Bay.
