While using a 3G/4G Deco, a SIM card is inserted into it for internet access. To protect your SIM card from embezzlement, PIN Management is available in the Deco app. When enabled, a PIN code is required when you reboot the Deco or reinsert the SIM card to it.

Follow the steps below to learn how to manage the PIN code in the Deco app. Here takes Deco X20-4G as an example. The actual app screen may vary slightly from the product model.


It is not available to use PIN Management when remotely controlled the network from the Deco app.

  1. Launch your Deco app and go to MORE > Advanced > PIN Management.


  1. Enable PIN Code and set a PIN code for SIM card unlock. Then the PIN code is required every time you reboot the Deco or reinsert the SIM card to it.

Note: The number of failed attempts to enter the PIN code is limited. If you enter the wrong PIN code too many times, your SIM card will be automatically locked. Contact your carrier for help if your SIM card is locked.


You will receive a notification in the Deco app as shown below every time you reboot the router or reinsert the SIM card. Tap View Details > UNLOCK SIM CARD. After you enter the PIN code, the network will be online again.
