Sources told Reuters on Tuesday that the German group was looking at a sale of the unit as part of a strategy to focus on offering packaged services, which include internet services as well as television and mobile.

Other options under consideration include a partnership, merging T-Mobile Netherlands with another company, or swapping the unit for a minority stake in another company, the person said. Deutsche Telekom earlier this year swapped its EE mobile phone operator for a stake in London-listed BT Group.
