The countdown to launch of the Personal Communications Network cellular mobile telephone service in the UK is well under way, and Mercury Communications Ltd’s Mercury One-to-One has released further details of its planned Personal Communications service, which will include cost control features. BillCheck, which will be part of the standard service available to all customers, enables users to call Customer Services at any time to check on how much they have spent so far in that month. The optional BillLimit feature enables customers to budget by setting a monthly limit. Mercury will then let customers know when they have reached that limit, so that users can choose whether or not to make further calls. Call waiting, call divert and call barring facilities will also be included in the package. Mercury One-to-One has also confirmed that it is to beta test the service before the launch, which is planned for this summer. A limited number of mainly business customers will be invited to try the service out.
