Overview
Optimus Comunicações, S.A. was a Portuguese mobile telecommunications operator offering GSM, UMTS and later LTE-related services under the Optimus brand. It began commercial operations on 15 September 1998 as a challenger to the two established Portuguese mobile operators, TMN and Telecel, the latter later becoming part of Vodafone. Optimus entered the market with an unusually aggressive customer-acquisition strategy, combining low introductory pricing, prepaid services and wide retail reach through businesses associated with its parent group, Sonae. A central element of the launch was the Pioneiros programme. Customers who registered before the commercial start could make calls to other Optimus users at a very low fixed rate for the life of the offer. The proposition helped the new operator build a community of early adopters and gave customers an incentive to recruit other Optimus users. Sonae's ownership of the Continente hypermarket chain also provided a large and accessible distribution network for acquiring customers and selling prepaid products. Optimus reached approximately 700,000 customers within its first year and held about 13 percent of the Portuguese mobile market by October 1999. The company continued to compete through prepaid plans, tariff innovation and mobile data services. Its Boomerang offer built on the prepaid-card model that had become especially important in Portugal. In 2000, Optimus's numbering prefix changed from 0933 to 93 as part of a national numbering-system change. The operator passed one million customers in June 2000, with prepaid users representing roughly four-fifths of its base, and its market share had risen to approximately 16 percent. It also secured one of Portugal's four UMTS licences in December 2000, positioning it for third-generation mobile services. Optimus expanded beyond basic voice and messaging through services such as Optimus Zone, a mobile portal launched in 2003, and Kanguru, a wireless internet-access proposition introduced in 2005 using GPRS and 3G. Kanguru Xpress followed in 2006 with HSDPA-based service and higher advertised download speeds. In 2008, the TAG tariff combined a monthly fee with unlimited or substantially discounted communications among TAG users, including voice, video calls, messaging and instant-messaging services. The offer triggered competing responses and contributed to a period of intense tariff competition among Portugal's three mobile operators. The brand's visual identity changed during the 2000s, including a move from green to orange in 2004, although the company did not become the Orange brand. Its advertising was handled by BBDO Portugal from 1998 to 2008 and by Euro RSCG Portugal from 2008 until the end of the Optimus brand. Campaigns and product innovations helped make Optimus a significant market challenger, even though it generally remained the third-largest Portuguese mobile operator by market share and financial performance. From 2012, Optimus's parent group and ZON Multimédia pursued a merger. The transaction received the relevant competition and media-regulatory scrutiny and was completed on 16 May 2014. Optimus Telecomunicações and ZON Multimédia were combined into a new company initially known as ZON Optimus and subsequently branded NOS. The Optimus brand therefore ceased to operate as an independent consumer mobile brand, while its network, customers and activities became part of NOS's Portuguese telecommunications business.
History
Optimus was established as a Portuguese mobile-network challenger in the late 1990s and began operations on 15 September 1998. Its initial competitors were TMN and Telecel, the two longer-established mobile operators in Portugal. The launch was supported by an extensive advertising campaign and by Sonae's retail presence, particularly through the Continente hypermarket chain. The operator's defining early commercial device was Pioneiros. Customers who registered before launch received a very low long-term calling rate for calls to other Optimus customers. This created an incentive for users to join the same network and helped Optimus overcome the disadvantage of entering a market dominated by established operators. The company also adopted prepaid products, including the Boomerang tariff plan. Within approximately one year, Optimus had reached 700,000 customers and about 13 percent market share. In 1999, Sonaecom broadened its communications activities by launching Novis as a fixed-line operator and Clix as an internet service provider and web portal. Optimus itself received international recognition in 2000 for Taxi Digital, which used its network for data communications between taxi-dispatch centres and vehicles. In the same period, Portugal changed its mobile numbering system, and Optimus's 0933 prefix became 93. The company reached one million customers in June 2000, while prepaid subscribers accounted for approximately 80 percent of its base. It also obtained a UMTS licence, preparing for the deployment of third-generation services. Optimus developed mobile content and data services during the 2000s. Optimus Zone, a mobile portal, was launched in 2003. In 2004, France Télécom became the major shareholder through its holding structure, while Sonaecom remained the relevant corporate context for Optimus. The brand's colour scheme changed from green to orange, leading to speculation that it might be replaced by Orange, but Optimus retained its own identity. Kanguru launched in 2005 as a wireless internet-access service using GPRS and 3G. Kanguru Xpress followed in 2006 using HSDPA technology, offering faster mobile broadband. In April 2008, Optimus introduced TAG, a tariff built around a monthly fee converted into communications credit and network-community benefits. TAG covered services including voice, video calls, SMS, MMS and instant messaging, with a computer-based communication application also available. Rival Portuguese operators introduced comparable offers, producing a period of aggressive tariff competition. The brand remained a significant but generally third-ranked mobile operator in Portugal. Its slogans and advertising identity changed several times, and its agencies included BBDO Portugal from 1998 to 2008 and Euro RSCG Portugal from 2008 to 2014. The company reported 3,639,400 customers in 2011, alongside average monthly revenue per user of €12.90; these figures are historical company metrics and do not describe the post-merger NOS business. Optimus and ZON began merger discussions in 2012. After regulatory and competition-related review, the transaction was completed on 16 May 2014. The combined company became known first as ZON Optimus and then as NOS. Optimus consequently ceased to exist as a standalone operator and consumer brand, with its business incorporated into NOS.
