They're all the same
They seem to all manage to have the same amount of confusion on their websites, making it as difficult as possible to find basic information.
The actual bundle prices with a phone are almost always more than buying a phone outright + a phone plan by a considerable margin too which is insane - you'd expect a discounted rate.
I've never really understood why anyone does it - but I imagine it's to do with the effective ease of the credit, plus the fact that many people really really don't understand what things cost - my friend for example changes his car every 3 years 'for free'...
"I pay £500 a month for my car loan. when it's finished after 3 years, I change to a new car and it still just costs me £500 a month) so it's free - why wouldn't you change"
that's their logic.. the fact my car was paid for 5 years ago and costs me nothing a month (in loans) is irrelevant apparently..
"no no you are missing the point - this new car is costing me no more than the old one"
IT'S A LOAN YOU ARS$HOLE! YOU JUST SPEND ANOTHER 15K ON A NEW CAR FFS.
and yeh - we're talking about a 'smart' guy - degree, good job...
now think of the young folk buying these 600 quid phones... it's them more than the oldies that the telcos are ripping off - but they seem too stupid to care.
