Sim Card Precautions - MTX -GTW II User Manual

3. SIM Card Precautions

Before handling the SIM card in your application, ensure that you are not charged with static electricity.
Use proper precautions to avoid electrostatic discharges.
• When the SIM card hatch is opened, the SIM card connectors lie exposed under the SIM card
holder.
Caution! Do not touch these connectors! If you do, you may release an electrical discharge that could
damage the modem or the SIM card.
• When designing your application, the SIM card's accessibility should be taken into account. We
always recommend that you have the SIM card protected by a PIN code. This will ensure that
the SIM card cannot be used by an unauthorized person.
