Maybe they do, but what's the betting that the 2025 deadline for ending voice calls via landline will be extended due to sheer numbers (probably of the elderly demographic due to our ageing population) who have made no alternative arrangements.
If they are going to do tat then first, they should make a hell of a lot more sure they announce it well enough that everbody will know, and second, they need to vastly improve the cellular network.
There is NO chance I will be getting rid of my landline in the foreseeable future, and I can't honestly see how very many people who don't live on their own can do so.
Currently, where I live, which is in a reasonable sized village in a prosperous and well populated area, mobile reception is poor enough that I really can't use my mobile for voice calls without using voice over IP - which means it is really using my landline.
But even if they improve that reception to the point where I could do so, I would still want the landline for broadband. If you are trying to use cellular data for that, it will be much more restricted (few mobile contracts provide unlimited data, many landline broadband contracts do), probably slower until 5G is available everywhere, and what happens if not everyone in the house has a mobile phone, and the one who does wants to go out with it?
