Ask HN: Bonding Internet Connections

Hi Guys - I'm based in Australia and have slow ADSL2+ (4Mb/1Mb down/up). I live semi rural so have limited to no mobile reception. I can get 'skymuster' which is a satellite connection that should provide about 20Mb down. That said I've has mixed reviews like it 1) stops working in heavy rain plus 2) accounts are limited to 200bg and I probably use double that in a month and 3) I run my mobile calls over wifi so worried about the latency of satellite only.

I’ve started looking at signing up to both services to get the best of both and bonding these 2 connections. The solution to bond connections that keeps showing up is Speedify. There doesn’t seem to be a huge amount of options for a non-technical person like me. I'm wondering if people have any recommendations on the best way to bond 2 internet connections?
