Replacing a SIM card
Your SIM card is a small rectangular plastic card that stores your phone number and important information about your wireless service. The FX3100 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 existing SIM card.
2. If necessary, remove the SIM card from the protective sleeve, being careful not to touch the gold-colored contacts.
3. 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 network operator.
