Many telecom providers in Belgium offer packages for TV, internet and mobile phone that also include a landline for a low price. Every provider has a different package but most of them come with a lot of extras. For example a discount on the first month of the subscription or on a smartphone.
Most of the Belgians have a package at home and getting a landline separately is not that popular. That is why there are only two providers that offer a separate landline service: Telenet and Proximus. If you subscribe for this service you can make unlimited calls to other landlines and mostly they also include a certain amount of minutes where you can make international calls and calls to mobile numbers.
