It sucks! Pages with lots of separate bits of content can take quite a long time to load, often over 30 seconds
I’ve just acquired a 2nd hand 4G phone, and discovered download speeds up to 5X faster than I get with Skymuster (best so far 111Mbps), and uploads speeds more than 10X faster (best 65Mbps so far), along with ping times >30X less (20-24ms vs ~700ms)… in places where I have 3 bars of signal. Unfortunately that isn’t at home, but even so the performance is far superior to nbn satellite.
I think I’ll be hotspotting my phone for much of the time when home, and am in the process of changing to a phone plan with 30GB/month as I type this.
