Mercury Communications Ltd, London has released details of its UK Personal Communications Network cellular service, to be launched this summer. It will be called One-2-One, the name under which Mercury Personal Communications Ltd will now trade. An integral answerphone will be included, as will Smart Card technology to enable users to share a phone by inserting their own cards. The company says it is aiming to reach 24% of the UK population by April 1994, but under the terms of Mercury’s licence, it must be a nationwide service by the end of the decade. Mercury is cagey on pricing, but it says that an agreement with British Telecommunications Plc means that incoming calls will be 50% to 70% cheaper than calls to cellular phones.
