My first phone was a Nokia brick - on Vodafone analogue, contract was with UniqueAir (Unipart group, later bought out by Vodafone).
Can't remember the costs and prices, but was in my final year at university, so was around 1995/6 ish.
My first GSM phone was the Nokia Orange 5.1, unsurprisingly on Orange contract. Didn't even have SMS at first, then I added the SMS option to my contract at something like £2 a month!
