"We live in a world where people can do price comparisons online."
You assume the average mobile customer is savvy enough to know this. My experience is that most people are stupid and just want to get by their day. They'll listen to word of mouth or (gasp) check out the deals in the windows. And since many people in the upper crust depend on stupid people to maintain their standard of living, stupid people will never go away.
"Its the same with broadband. We all know BTs claim to have the best wifi in the country is bollocks."
No we don't. Remember P. T. Barnum's words: "a sucker born every minute."
"How many of you want to rush out and sign up for BT on the strength of their crappy router?"
More than you think.
"Give me a £50 a month SIM only genuinely unlimited package and im in. No throttling, no peak time bullshit, no tethering restrictions (another bullshit arbitrary restriction) and no fucking about."
They'll never give it. Limited spectrum and cartel behavior guarantee this via a captive market, leaving you with the Hobson's Choice: take it or leave it, and then find yourself in the lurch when you REALLY need to be accessible in the field.
"Also, why not make mobile networks regional rather than national like the energy companies. We'd all be better off that way since operators will be responsible for smaller areas of coverage and wont be tempted to only install infrastructure in 'profitable' areas."
Because spectrum is a NATIONAL resource, controlled by the central government (has to be that way due to other radio functions like weather, television, and especially mandated things like the military, plus it's inherently an interstate/interregional business). Makes it pretty much an all-or-nothing.
