Install SIM cards
To install SIM cards:
- On the WR64 front panel, use a screwdriver to remove the SIM slot cover.
- For high-vibration environments, apply a thin layer of dielectric grease to the SIM contacts.
Note If the WR64 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.
- Insert the SIM card(s) into the SIM sockets. Insert the end of each SIM card with the chamfered corner first and the SIM contacts facing upwards:
- After all SIM cards are in place, replace the SIM slot cover.
