It's all dependent on where you are and your access to a solid 5G connection. You can get a 5G router through Vodafone for £35 a month with unlimited everything, and then you can take that on the go if you needed/wanted to work away from a lined connection. You'll get faster speeds in a good connection area than you are likely to find on anything non-fibre on 5G (quick test on my iPhone gives me 108mbps down, 22mbps up).I'm working at home a lot now, and cannot really afford for the internet to go down. In short, and lay terms as I do not know much bout this, I have a regular domestic internet service but want back-up in case this goes down. I can use my phone hotspot for short disuptions, which I have done recently, but it got me thinking what if it went down for a long period.
Thanks for the help everyone.
For what you seem to need it for this is probably the most convenient bet. Very unlikely to find two outages at the same time from two completely different sources.
