> It has the advantage of working pretty much anywhere with a view of the sky so no relying on mobile network coverage.
I'm also not sure if $25/month is anything close to the global average for unlimited 4G/5G data (if even available).
US plans just aren't comparable as they've been historically f'd with astronomical monthly payments.
Orange Yoxo is the only one which has actually-unlimited, all the others have a fine-print somewhere with "up to X GB/month, then bandwidth is severely throttled".
I'm using the 4.9€ plan for a mountain webcam[1] and they have been true to their word, no throttling so far.
I can get close to £10/mo but that's because I'm already paying that carrier ~£30/mo for two separate SIMs (mine and my kid's).
The £9/mo deal offered below is just half price for 6 months, it then becomes £18/mo.

The bottom of the page does give some details about what "unlimited data" means here in the UK between the different carriers. Some cap speeds, some monitor usage and then either turf you off on "fair use" grounds or do traffic management/shaping. The general rule seems to be 650GB in 6 months is just about the limit of what is ok.
That wouldn't be anywhere near enough for me. Looking at my router I see I've downloaded 522GB in the last 34 days alone.
Also when there's a fiber cut, it usually takes out everyone since there are frequently shared conduits or poles.
Everyone reverting to mobile usually takes everyone out.
Local failures don't matter unless your country doesn't allow landing user traffic in other countries (Indonesia, Bangladesh)
