Company history


Former logo of the mobile phone business in Germany

The origins of T-Mobile's business lie in the car phone activities of the Deutsche Bundespost , namely the so-called B and C networks , which were in operation until 1994 and 2000 respectively.

On July 1, 1992, T-Mobile Deutschland started operations as an economically independent company with 1200 employees under the name De.Te.Mobil Deutsche Telekom Mobilfunk GmbH . At the end of the following year, the company had 480,000 customers. In March, the first short message ( Short Message Service , SMS) went over the D1 network. The Scall paging service was introduced. In 1995 the name was changed to DeTeMobil Deutsche Telekom MobilNet GmbH ( T-Mobil for short ). In 1996 the paging service Skyper was introduced, in 1997 the first German prepaid card . In 1998, the Regulatory Authority for Telecommunications and Post (RegTP) assigned T-Mobile to 0171 as an additional area code .

On January 1, 2000, Deutsche Telekom bundled its international mobile communications activities in T-Mobile International AG . In addition to T-Mobile in Germany, the new holding company initially included the British One2One (now T-Mobile UK ) and the Austrian max.mobil. (now Magenta Telekom ) as well as the majority and minority holdings RadioMobil (now T-Mobile Czech Republic ), PTC ( Poland ) and MTS ( Russia ). The area codes 0160, 0175, 0151 were introduced. In August, T-Mobile acquired a UMTS license with three frequency blocks. In June, T-Mobile is the first operator in the world to start the technical network start of the data transmission standard GPRS ( General Packet Radio Service ). The analog C-Tel network was switched off. The radio call services Scall , Skyper and Cityruf were sold to the Berlin based e * Message WIS Deutschland GmbH (e * Message) and continued to be operated by them.

In February 2002, DeTeMobil Deutsche TelekomMobilNet GmbH was renamed T-Mobile Deutschland GmbH . In July, T-Mobile launched the Multimedia Messaging Service (MMS). In 2004, T-Mobile became the second German mobile operator to activate its UMTS network for all customers. In September 2004, T-Mobile was the first German network operator to show the push-to-talk feature at the YOU 2004 youth fair . In November 2005, T-Mobile received numbers in the area code 01515.

On June 19, 2007, T-Mobile switched to the third expansion stage of HSDPA in important connection areas, which should now enable speeds of 7.2 Mbit / s. At the same time, HSUPA started operating and, in addition to significantly improved ping times, also offered an upload of a maximum of 1.4 Mbit / s. From 2008 numbers in the area code 01512 and 01514 were assigned. Furthermore, the entire EDGE network infrastructure was upgraded to a possible bandwidth of up to 260 kbits / s. In October, T-Mobile shows the world's first LTE handover .

On April 1, 2010, Telekom Deutschland GmbH officially launched. T-Mobile Deutschland GmbH was merged with its sister T-Home in this company.

On May 20, 2010, Telekom successfully participated in the largest German frequency auction to date in Mainz . On December 1, pilot customers in Brandenburg and Baden-Württemberg tested LTE. On April 5, 2011, LTE started with the Call & Surf Comfort tariff via radio . The tariff is intended as a DSL replacement for underserved areas. Since June 1, Cologne was the first metropolitan area in which Telekom enabled the fastest mobile data connection to date with LTE (1800 MHz). On November 2nd, the company introduced HD Voice in the UMTS network.

On August 30, 2012, the partnership with the music streaming service Spotify was announced. Since October the group has been offering a tariff (Special Complete Mobile Music) that already includes the Spotify Premium option. At the beginning of December, the additional booking option for landline and mobile customers followed. The online use of the Spotify streaming service is not offset against the data volume included in the tariff and after the monthly data volume has been used up, Spotify has been excluded from the throttling of Internet traffic. As of April 28, 2016, Spotify will no longer be exempted from throttling Internet traffic after the monthly data volume has been used up. Since August 2, 2016, the Spotify tariff for new customers has only been offered without Spotify's exception to the monthly data volume.

On April 15, 2013, the company announced that it would replace the previous Complete Mobile tariff portfolio with the new Complete Comfort tariffs on May 22, 2013.

On June 17, 2014, the company announced in a press release that it would offer LTE roaming in six European countries (Belgium, France, Italy, Norway, Poland and Spain) at no extra charge. Great Britain and other countries are to follow shortly.

At IFA 2014, the company presented the Magenta-Mobil tariffs, which replace the Complete Comfort and Complete Premium tariffs.

In mid-November, the company increased the speed in the LTE network by means of bundling (also called carrier aggregation ) from 1800 MHz and 2600 MHz spectrum to 300 Mbit / s.


On June 1, 2006, the Federal Court of Justice approved the merger of T-Online International AG with Deutsche Telekom AG. The merger was finally completed on June 6, 2006 with the entry in the commercial register. All previous business activities of T-Com and T-Online have thus been merged under the T-Com brand . T-Online became an independent business unit of T-Com.

At the presentation of the new corporate strategy of Deutsche Telekom AG on March 1, 2007, CEO René Obermann announced that from summer 2007 the brand image will be radically simplified in order to better orient private customers in Germany: T-Home is to stand for all telecommunications offers of Deutsche Telekom, that are used at home. T-Home was launched with an advertising campaign on May 19, 2007, and landline telephony, Internet and IPTV products have been marketed under this brand ever since.

Customer communication for invoicing takes place up to and including March 2008 under the T-Com letterhead . Since April 2008, the simple Telekom logo (Magenta-T with the digits) has been used on the invoice letterheads without any other brand names. T-Com disappeared from the sender details in March 2008.

Fields of activity

Until the merger with T-Online, T-Com was the classic business area of ​​Deutsche Telekom AG, which it took over from its legal predecessor , the Deutsche Bundespost , after the postal reform . The fixed line division is the area that has generated the greatest profits over the past few years and thus enabled the establishment of the new business areas of mobile communications, online and business and system customers . T-Com had recently marketed 39 million telephone connections, 33 million of them in Germany, which made T-Com a quasi-monopoly there.

T-Com operates two line networks in Germany: On the one hand, the digital T-Net , also known as the classic circuit-switched telephone network in Germany, and on the other hand, the DTAG-IPnet , a high-performance fiber optic network ( backbone ) between 74 locations in Germany and several others abroad, which is used for the transmission of Internet data traffic. T-Com is currently building an NGN -O platform ( Next Generation Network Overlay) with which the functions of these two separate networks will be temporarily connected. The NGN overlay platform ensures a transition between the Internet and the conventional telephone network (click to dial).

In south-eastern Central Europe, T-Com is an established network operator in the case of the Hungarian Magyar Telekom , Slovak Telekom and Croatian T-Hrvatski Telekom, as in Germany . Bosnia-Herzegovina occupies a special position , where Deutsche Telekom AG received the order to rebuild the telephone network that was destroyed by the civil war.

In the case of its former foreign holdings in Western Europe, on the other hand, it was present on the markets as a competitor without its own last mile , who used the advance services of the established providers there to connect customers. After the network operator activities in Austria had been discontinued a long time ago, the Internet subsidiaries Club Internet in France (to Neuf Cegetel ) and in Spain as well as Terravista in Portugal to France Telecom were also sold in spring 2007 because there, despite Establishing own ADSL2 + access networks, a sufficient broadband market share could not be achieved. These foreign holdings were held by T-Online AG before the reintegration into T-Com.

In the future, Deutsche Telekom plans to concentrate its foreign holdings on the mobile communications sector, where greater growth potential is expected.

Other business activities of T-Com include a. the operation of the Telekom Shops (formerly T-Punkt ), which has now been spun off into a GmbH , in which it sells its own products and services as well as those of the other DTAG business areas to end customers; and the publication of telephone books via its subsidiary DeTeMedien .

In November 2018, Telekom Deutschland GmbH announced that it would build a charging infrastructure for electric cars through its subsidiary COMFORT CHARGE. For this she would receive funding from the federal government. However, the first tariff models were unattractive for the target group. Telekom Ladestrom was founded as a subsidiary in December 2018. Telekom Ladestrom cooperates with existing charging station operators. The charging card, which is required together with an app for charging and billing, can be ordered online. With the RFID chip contained in the charging card, charging stations for electric cars can be activated. In the introductory phase until the end of March 2019, every minute of charging time at the preferred charging stations costs 2 cents. The charging current can also be obtained from a number of other charging stations - albeit at unattractive prices. On April 1st and 2nd, charging at the preferred charging stations is free. On April 3, 2019, Telekom Ladestrom will be renamed GET CHARGE. The charging of electric cars is then no longer billed according to the charging time, but according to the amount of energy used in kWh.

Brand history T-Home

Originally, Deutsche Telekom marketed a variant of its broadband Internet connection T-DSL under the T-Home brand from 2006 , with which you could also watch television programs in full resolution on your computer or television, making it the fourth distribution channel in competition with the three classic reception options terrestrial , cable and satellite should be used. (Conversely, the cable companies had recently started offering telephone and Internet connections.) This service is still offered by Deutsche Telekom (under the name Telekom Entertain ).

However, the use of the T-Home brand changed fundamentally from May 19, 2007: Since then, all of Telekom's landline- related services ( landline telephones (analog and ISDN ), Internet , DSL and IPTV ) have been grouped under the T-Home umbrella brand ; the previous umbrella brand T-Com was given up in Germany, but is still used in numerous other countries (Croatia, Montenegro, Slovakia) today. Only in Macedonia and since the end of 2008 in Hungary have they also switched to T-Home .

T-Home was chosen as the name in order to set it in clearer contrast to the mobile services grouped under T-Mobile ( mobile communications , hot spots ).

Under the former CEO Kai-Uwe Ricke , T-Com had only replaced the original T-Net brand a few years ago, which originated from the time of the first Telekom CEO Ron Sommer . With this, apart from the two interim board members Helmut Ricke and Helmut Sihler , every CEO of Deutsche Telekom has renamed the fixed-line business.

Advertising and sponsorship

Telekom Deutschland GmbH is active as a sponsor in culture and sport, for example at the 2004 European Football Championship and the 2006 FIFA World Cup finals in Germany.

From 1991 to 2007 Telekom also supported the professional cycling team Team T-Mobile . On November 27, 2007, however, the Board of Management of Deutsche Telekom AG announced that it would withdraw from cycling with immediate effect in order not to further damage the Group's reputation with the doping scandals of 2007 . With the Telekom Extreme Playgrounds event series, which combines action sports and music, Telekom is deepening its cycling commitment in the BMX sector.

With the Telekom Streetgigs, a free series of concerts was launched. So-called “ mobile tickets ” are used here. Since July 16, 2002, there has been an official learning partnership between Telekom Deutschland and the Carl-von-Ossietzky-Gymnasium (CvO) in Bonn.

From 2006 to 2009, T-Home (initially under the old name T-Com) was the official sponsor of the 1st and 2nd Bundesliga, the T-Home logo was on every soccer jersey of the teams from both leagues see left sleeve. In addition, Deutsche Telekom would have had the right to change the brand name “Bundesliga” to “T-Home Bundesliga” for a surcharge. B. is the case in Austria (" tipp3-Bundesliga powered by T-Mobile "). However, in consultation with the German Football League , this right was waived.

Since 2002, Deutsche Telekom has been the main and jersey sponsor of FC Bayern Munich , which is responsible for the T-Home and LIGA total! advertises. On July 18 and 19, 2009, Deutsche Telekom hosted a football tournament called the T-Home Cup (2010–2012 LIGA total! -Cup , today Telekom Cup ) for the first time.

1 & 1 vs. Telecom

Since September 2015, there has been a public dispute between Telekom Deutschland GmbH and 1 & 1 . 1 & 1 started with a comparative commercial : at an Oscar- style award ceremony , the company competed for 1st place in Telekom's “Best Network”. In the commercial, the company referred to the test result in the DSL test conducted by Connect magazine . Telekom's reaction to this was also a commercial in which it alluded to poor cell phone reception at competitor 1 & 1. In the spot, Telekom also referred to a test result from the same magazine, albeit on the result of a mobile network test. In this test she was able to take first place four times in a row.

“Surprise winner 2015: The active provider from Montabaur buys mostly cables and services - but obviously the right ones. 1 & 1 ends up in first place. "

- Hannes Rügheimer : DSL test from Connect 2015


Since 2015, Telekom has switched to IP telephony for private analogue and ISDN telephone connections . The company is not afraid of issuing a forced termination after the end of the contract period. A serious disadvantage with this technology: If the power fails, the telephone line is automatically interrupted. Especially people who use a home emergency call system are dependent on this reliability.

Telekom also uses its large customer base to offer service providers peering contracts that are well above the market price. The strategy is to keep the capacities artificially small by too high prices and to recommend the affected customers to file a complaint with the hoster, so that the pressure to expand capacity (with a correspondingly high price) increases. On the other hand, Telekom justifies the resulting bottlenecks, "It is up to the remote station and not us" in order to give the affected customers the feeling that they are still using the best network. Telekom was criticized in this regard because there were problems with YouTube in 2015, with Apple at the end of 2018, with Fastly at the beginning of 2019 (e.g. Reddit is hosted there) and partly also with Steam, where Telekom customers play very slowly in the evenings and were able to download updates, although customers from other operators had no problems. Telekom was also sued for its act. The hosting provider " Hetzner " and the Internet provider 1 & 1 Versatel have each published articles on the subject. For the customer, it means above all that some services may only be usable to a limited extent or not, although customers of other providers do not experience any problems.
