UK's first mobile phone user remembers his call 30 years on
Michael Harrison has recalled making history 30 years ago on New Year's Eve, when he left a family party to make Britain's first mobile phone call.
The recipient was his father Sir Ernest Harrison, the chairman of a new firm called Racal Vodafone.
Vodafone was one of two firms given a licence to operate a new cellular phone network - and it was in a race to beat its rival BT Cellnet to get up and running first.
It succeeded - Cellnet's first call came a few weeks into 1985.
