The CTM-500 supports two mini 2FF style SIM cards. One or two SIMS can be installed. For single SIM card installation, the SIM card may be inserted into either slot, labelled SIM1 and SIM2.
‘SIM2’ slot is located at the top and ‘SIM1’ slot is located at the bottom.
SIM card insertion and removal
Unlock the SIM card door by sliding it to the left until the door unlocks, then swing the door open.
For single SIM card installation, insert the SIM card into either of the slots of the dual SIM holder. Ensure that the copper contact is facing upwards (chamfered corner to the front left).
If applicable, the second SIM card can be inserted into the other slot of the dual SIM holder.
Close the SIM door securely by sliding it to the right until a ‘click’ is heard.
