Portugal Telecom SGPS SA (also known as PT) is the largest telecommunications service provider in Portugal. Although it operates mainly in Portugal and Brazil, it has also a significant presence in Guinea-Bissau, Cape Verde, Mozambique, Timor-Leste, Angola, Kenya, and São Tomé and Príncipe.
Due to its large market share, Portugal Telecom is considered a de facto monopoly in fixed telephony in Portugal.
In 2013, Oi announced its merger with Portugal Telecom, the largest telecommunication company in Portugal, in order to strengthen the Brazilian firm and simplify its ownership structure.
