Check that the device is receiving power and verify the polarity of the power connections; the unit has reverse‑polarity protection but will not operate until the correct polarity is restored.
Remove the two bottom screws and the antenna screw, open the case, insert the SIM card into the slot as shown, then re‑assemble the case.
Use a DC power source of 5 V/500 mA or higher; the device can accept 5–60 V DC but a stable 5 V/500 mA supply is recommended for reliable operation.
