Thing is, yes. Yallo or wingo or all those providers are "cheaper". But - for example in the case of yallo, you get double-natted - which means you could not really set up a home server accessible from the outside world even if you wanted to. Then, there's also the support of wingo and yallo and so on which is... Terrible. I actually ordered yallo Internet at first because I got sold on it over the phone - the next day, before anything got shipped or anything, I wanted to annul my contract because, well, I found out about their shitty stuff. I was redirected like 8 Times across 8 levels of 'support' until I got it through.
I went for init7. Day it was supposed to go up, it didn't. Phone support was competent, said everything looked ok from their end. If I was sure the problem wasn't on my end (router, settings, fiber), they could send a technician along the next day - but if the problem would end up being on my side, I'd have to pay for it. As I was sure about what I was doing, the next morning I had a competent technician in my apartment who within 20 minutes total identified the issue and fixed it (broken fiber in the distribution center). That is good support.
I am willing to pay more to support init7, because they're doing great work.
But yes, we have lots of low cost options. For example, I pay 23 bucks a month with yallo for unlimited 5g data, calls and SMS across the whole of Europe.
