=== Rebranding ===
In 2002, the Matáv Group obtained group-level certification in accordance with [[ISO-9001:2000|ISO 9001:2000]], certified by [[SGS S.A.]]<ref name=":0" />

Matáv also wanted to lead telecommunications and Internet services in Hungary, as evidenced by the 100,000th [[ADSL]] subscription acquired in December 2003. In mobile telephones, number portability was a minor difficulty, but the Westel division of the group solved the problem in 2004.<ref name=":0" />

In March 2004, the group decided to replace the Westel name, which had existed since 1989, and joined the global [[T-Mobile International AG|T-Mobile]] brand on 1 May 2004. Subsequently, the Matáv Group decided to consolidate and merge, subordinating the structure of the group of companies on 1 January 2005, and then on 6 May all its services and operational organizations under central management and the group of companies. It changed its company name, and from that date, the Magyar Telekom Group operated as a group of "T" brand names.<ref>{{Cite web|date= 5 April 2005 |title=Hungary's Matav Changes Name|url=https://www.lightreading.com/hungarys-matav-changes-name/d/d-id/613198|access-date=23 June 2020|website=Light Reading|language=en}}</ref>
