FRITZ!Box 7390 – Service

Do telephones connected to the FRITZ!Box work when it is not plugged in?

Your FRITZ!Box must be plugged in; otherwise, you cannot use the telephones connected to it to conduct calls.

Note:However, if the telephone does not require its own power supply and you have a landline, then you can connect the telephone directly to your landline if there is a power outage.
