Install SIM cards

To install SIM cards:

  1. If the 6300-CX device is used in an environment with high vibration levels, SIM card contact fretting may cause unexpected SIM card failures. To protect the SIM cards, Digi strongly recommends that you apply a thin layer of dielectric grease to the SIM contacts prior to installing the SIM cards.
  1. Insert the SIM card(s) into the SIM sockets. Position the SIM cards to match the diagram on the device.
