TMN Enters New Stage of 3G Strategy

Lisbon, Portugal, 1 June 2005 – Portugal Telecom, SGPS, S.A. (PT) announces that TMN, its domestic mobile subsidiary, has entered into a new stage of the development of 3G services in Portugal, in line with its strategic objective of reinforcing its leading position in the Portuguese mobile market. TMN currently has over 5 million mobile customers, which represents approximately 50% market share of active customers.

Having completed one year since the commercial launch of 3G services in Portugal, TMN is leveraging on the experience gained during this period to initiate a new stage in its 3G strategy.

Based on the encouraging outcome of the usage and ARPU patterns experienced by the customers that migrated to 2.5G and to 3G, TMN believes that it should now initiate a proactive strategy of customer migration into 3G. TMN expects to achieve a total of 1 million 3G customers by the end of 2006. TMN believes this enhanced migration should underpin customer revenues, partially offsetting the negative impact of the recent regulatory measures with regards to cuts in terminating fees. Preliminary data indicates that the ARPU of a customer that moves to 3G increases on average by 20%.

To date, TMN has launched a set of innovative 3G services, such as video-calling, video-mail, video-portal, video-call-centre. TMN has announced that it will be the first operator to launch video-sharing in the Portuguese market in June. In terms of the corporate segment, TMN provides an outmail service (using Qtek handsets) to its customers, as well as the only datacard in the Portuguese market compatible with GPRS/UMTS/WiFi. TMN expects to increase the weight of non-SMS revenues from the current level of 15% of data revenues to 20% by 2006. This should drive total data revenues contribution to service revenues from the current level of 11% to 15% by end of 2006.

The expectation of a continued decline in the price of 3G handsets combined with the improvement of the quality and breadth of the handset portfolio also contributed towards TMN’s decision to enter this new stage of 3G rollout. The price of high-end 2.5G and 3G handsets is now similar, while in terms of mid-range phones the gap is expected to close by the end of the year. TMN has already reached an agreement with Nokia and Samsung for exclusive handsets in the high-end range. Additionally TMN has also entered in several content agreements, in the areas of news, sports, entertainment, finance, among others, with special emphasis on local content as a differentiating factor. TMN believes that these agreements for handset and content will create a competitive advantage in the 3G market which should reinforce TMN’s leading position in this segment.

TMN will also leverage on its strong cash flow profile and underlying profitability to step up the commercial efforts related to this new stage of the 3G strategy in Portugal. Considering the higher level of subscriber acquisition and retention costs (SARC) and the increase in telecom costs related to a more aggressive rollout of the 3G network, TMN believes that EBITDA could decrease by 5% to 10% in 2005 compared to 2004. Capex should increase to a range of Euro 200-220 million in 2005, as a result of a faster rollout of the 3G network. Approximately 70% of network capex should be spent on 3G in 2005. TMN plans to have coverage of 65% of population and 30% of the territory at the end of 2005 and over 80% of population and 50% of territory at the end of 2006.

• Total capex of Euro 200-220 million in 2005, as a result of acceleration in 3G rollout (Euro 20-40 million);
• Net additions of 200-250 thousand in 2005;
• 3G Customers: 1 million at the end of 2006;
• Target of 50% market share of 3G customers;
• Increase in operating costs in 2005 as a result of:
  • Costs related to subscriber acquisition, retention and migration: Euro 40-60 million;
  • Costs related to acceleration of network rollout: Euro 15-20 million;
• Negative impact of cut in termination rates in 2005 of circa Euro 80 million in revenues and circa Euro 50 million in EBITDA;
• Revenue growth of 0% to -5% in 2005;
• EBITDA growth of -5% to -10% in 2005, assuming a continued increase of data revenues and customer growth until the end of the year.
