The only things I subscribe to are periodicals, or publications. I have no subscriptions to any form of social media, although, obviously, I pay a monthly fee for high speed broadband & wifi internet access with what used to be the State telephone company.
I have a paid subscription to The Economist, and to Foreign Policy. Both of these allow for hard copies (to be delivered) and for online access.
Re mobile phones, I used to have a paid subscription, and found it an utter nuisance, as I have often been sent abroad (to the sort of places where that company could not provide any sort of mobile coverage) at short notice for months on end, and thus, had no use whatsoever for it.
Suspending the various mobile phone contracts, with a view to renewing them subsequently, proved impossible, as did arranging any sort of flexibility in these contracts. Anyway, at work abroad, I always had an official work phone, and so didn't have to use my own.
These days, when I am home, I use a pay-as-you-go system on my personal mobile.
For my mother, we have cable TV, which includes the main terrestrial channels and a few cable channels. I am not particularly happy with the service and range, but, as I don't watch much TV, and as my mother (who has dementia) is perfectly happy with it, for now, I have done little except for some desultory research into what other options may be available to us.
