Usage tips
Compound word
'Festnetz' (landline network) is a compound noun made from 'fest' (in the sense of 'fixed', 'not movable') and 'Netz' (network). So it describes a network that is tied to fixed lines and locations.
EXAMPLE
Früher hatte fast jeder Haushalt einen Anschluss für das Festnetz.
In the past, almost every household had a landline connection.
Correct preposition
A distinction is made between 'im Festnetz' (when you are calling via a landline connection) and 'ins Festnetz' (when the destination of the call is a landline connection).
EXAMPLE
Ein Anruf ins deutsche Festnetz ist in meiner Flatrate enthalten.
A call to a German landline is included in my flat rate.
Typical collocations
Common phrases are 'aus dem Festnetz anrufen' (to call from a landline), 'ein Anruf ins Festnetz' (a call to a landline), or 'ein Festnetz-Anschluss' (a landline connection). The term is often used in price lists from telephone providers.
EXAMPLE
Wie lautet deine Festnetz-Nummer?
What is your landline number?

Festnetz vs Handy
mobile phone / cell phone
'das Handy' and 'das Festnetz' are both related to making phone calls, but they stand for different types of connection. A 'Handy' is mobile and works via the mobile network. 'das Festnetz' is tied to a fixed connection and runs through physical lines. The words can be confused when someone asks for a phone number. A mobile number usually reaches a person while they are out and about; a landline number is more likely to belong to an apartment, an office, or a fixed connection. The simple contrast is: 'Handy' means mobile, 'Festnetz' means fixed-line.
Festnetz
Über das Festnetz erreicht man meine Eltern abends am besten.

Handy
Bei der Bewerbung gebe ich lieber meine Handynummer an.
For the application, I prefer to give my mobile number.
