Can I watch 4K Netflix on 20 Mbps?

Yes. Netflix 4K is rated at 25 Mbps but adaptively scales — at 20 Mbps you get genuine 4K on most titles, occasionally dropping to 1080p on the most demanding scenes.

Is 20 Mbps enough for a couple working from home?

For one person on Zoom/Teams while the other browses or streams — easily. For two simultaneous video calls plus background streaming, step up to 40 Mbps.

How does 20 Mbps compare to 10 Mbps?

Double the headroom for streaming, real 4K support and comfortable space for a second device. For couples, 20 Mbps is the meaningful upgrade — 10 Mbps starts to feel tight the moment two people are home.

How much does 20 Mbps fibre cost in South Africa?

Typically R449–R549/month uncapped, depending on the network and ISP. See the live deals table above for current pricing across Webafrica, MWeb, Afrihost and RSAweb.
