Orange Nederland merged with T-Mobile Nederland in 2007. The merged entity retained the T-Mobile brand. This was unlike the merger between Orange and T-Mobile in the United Kingdom, where both Orange and T-Mobile were discontinued in favour of a new brand (EE).
In 2002, Deutsche Telekom acquired Ben from Belgacom and Tele Danmark and launched operations with the T-Mobile brand, with the Ben brand being discontinued (it was revived in 2008).
In November 2018, T-Mobile Netherlands merged with the Dutch subsidiary of Swedish telecom company Tele2. The merger was completed in January 2019, with Deutsche Telekom owning 75% of the merged company and Tele2 the other 25%.
