Yes - I'd echo what Andrew says, 4G may be a solution.
For example - I'm on a 2.5 Mbps download / 0.3 Mbps upload ADSL (not even ADSL2+) connection, on a long EO (Exchange-Only) line, in a rural area, with little to no chance of ever getting FTTC or FTTP.
Also - I can't even get a 4G signal on my phone (and 3G is very poor too).
However - using a special 4G router, there's one location in 1 window upstairs that I can get 1 bar of 4G signal, as the external antennae for the router are much more sensitive than in a smartphone. I've also got an external omni-directional antenna, in case I need it.
I use EE - check your coverage to see if you can get 4G in your area:
EE Coverage Checker
If you can get coverage - then check out the Data SIM-only plans:
EE Data SIM-only Plans
I've got the 32Gb rolling 30-day plan, it was on special offer recently at half price (£14.50 per month), keep an eye out (via the EE website and also
HotUKDeals.com) as they often do similar deals every few months. And if 32Gb data per month isn't enough, there are 50Gb, 64Gb or 100Gb options available, although expensive (unless on special offer).
And if you can't get coverage with EE - then maybe you can with Three, O2 or Vodafone (or one of the networks based on these) - just get a trial SIM and put some credit on it to try it out.
The router I use is:
TP-Link Archer MR200
External Antenna:
Solwise External Omni-Directional 4G Antenna (I haven't actually needed to use this yet, but will try it when the weather improves, and install it if it boosts my 4G signal strength).
As the 4G router is upstairs, I use Powerline adapters to "pipe" the connection via Ethernet & WiFi to other parts of the house.
I get, on average, 20 Mbps downstream (sometimes more) and 10 Mbps upstream speeds, much better than my ADSL.
I still use my slow PlusNet ADSL connection too, as this has unlimited data cap, so the 4G doesn't replace it, just acts as a "turbo speed booster" for when I really need it - in your case, you could use a 4G connection to upload your YouTube videos, for example.
Good luck anyway - maybe 4G will be a viable option for you, at least for now until / unless you eventually get a fibre-based fixed line solution.
I do agree with everyone else though - I don't think broadband is a Human Right, it's more a "nice-to-have" utility (a bit like mains gas - where I am, there's no mains gas, we do have water & electricity though!!).
Water and shelter & warmth & food are human rights.
Like you, I'd love a much better fixed-line broadband - but I doubt I'll ever get that (maybe it will improve in the next 10 years, things can change), so it's worth exploring other options. I'm self-employed and run a business from home (although have to supplement it with extra part-time employment), so I'm well-aware of the frustration that slow internet connections can cause. People in our situation will just have to be patient!
I hope this helps a bit.
Kind regards,
Adam.
