Mobile Networks
===============

The Librem 5 is designed to work on a wide range of mobile networks. The modem you chose should already be installed in the phone, and it should be suitable for your region. To start using the phone for calls, messaging and cellular data services, you need to install a SIM card and enable it. This is normally done when you :ref:`set up the phone <librem_5_setup>`.

The sections below cover each step in the process.

Switch on the Modem
-------------------

The phone cannot configure the mobile network without access to the modem. If the modem is disabled, slide the switch into the enabled position, away from the SIM slot.

The modem should now be enabled.

Unlock the Phone Screen
-----------------------

If the screen is locked, unlock it by sliding the arrow up to reveal the keypad. Unlock the phone by entering your passcode as usual.

If the SIM card was not unlocked when the phone was powered on, this page will show that the SIM card is locked.

Press the **Unlock** button to start the process of unlocking the SIM card. You will be prompted to enter the PIN code for the SIM card -- this will have been supplied by your mobile network service provider.

Enter your PIN code using the on-screen keyboard and press the **Unlock** button. You only have a limited number of attempts to enter your PIN code, so take care to enter it correctly. Once the PIN code has been entered, the settings will be shown.
