Your SIM card is a small rectangular plastic card that stores your phone number and important information about your wireless service. The FX4100 cellular router supports only Nano SIM cards. To replace a SIM card, select the correct SIM for this device.

CAUTION! Always use a factory-made SIM card supplied by the service provider. Do not bend or scratch your SIM card. Avoid exposing your SIM card to static electricity, water, or dirt.

To replace a SIM card:

1. Remove the SIM/EXTERNAL ANTENNAS cover on the back of the router.

2. Remove the existing SIM card.

3. If necessary, remove the SIM card from the protective sleeve, being careful not to touch the gold-colored contacts.

4. Insert the SIM card into the SIM slot notch first, with the gold-colored contact points facing down.

NOTE: Should your SIM card be lost or damaged, contact your service provider.
