FRITZ!Box 6850 LTE Service

Setting up FRITZ!Box for internet access via the mobile network (LTE/UMTS)

The FRITZ!Box Cable is ideally prepared for internet access via the mobile network. All you have to do is insert your SIM card into the FRITZ!Box and enter the PIN in the FRITZ!Box user interface, and then the complete FRITZ!Box range of functions for internet, telephony, and multimedia is available to all devices in your home network without restriction.

Requirements / Restrictions

  • Depending on the mobile network operator, functions that require a public IP address (for example receiving incoming VPN connections) are either not available, only available with at home packages, or only available to a limited extent.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Inserting the SIM card into the FRITZ!Box

  1. Insert the SIM card (mini-SIM, 25 x 15 x 0.76 mm) that you received from your mobile network operator into the SIM card slot with the slanted edge of the card on the left and the contacts facing down.

    Important:Do not use SIM card holders with micro or nano SIM cards that have already been punched out because they can get jammed and damage the SIM slot.

  2. Push the SIM card gently into the SIM card slot until it clicks into place. A few millimeters of the SIM card protrude from the SIM card slot.
