Vodafone Group Plc's sweeping disclosure of wiretapping on its network worldwide means technology and phone companies could follow by revealing how much access governments are seeking to phone calls, data and e-mails. Deutsche Telekom AG, with 145 million wireless customers in Europe and the U.S., said it may increase disclosure after Vodafone last week released its law-enforcement transparency report, the most comprehensive by a global telecommunications carrier. Vodafone said 29 governments from Albania to the U.K. asked for access to its network or user data, with requests ranging from intercepting calls and messages to accessing data such as conversation and Web-browsing records.
