FRITZ!Box 6840 LTE Service

Setting up the FRITZ!Box for internet access via LTE

The FRITZ!Box automatically connects to the internet when you insert your SIM card into the FRITZ!Box and enter the PIN in the FRITZ!Box user interface. All of the computers, smartphones, and other devices connected to the FRITZ!Box can then use the internet connection at the same time and have equal status.

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. Pull the card holder completely out of the SIM card slot (see fig.).
  2. Place the SIM card (mini-SIM, 25 x 15 x 0.76 mm) supplied by your LTE provider with the slanted edge in the bottom right corner with the contacts facing downwards. Do not use micro or nano SIM cards that have already been punched out.
  3. Insert the card tray with the SIM card back into the SIM card slot.
