Possible Causes

Improperly seated SIM card, Expired or locked SIM, Faulty 4G/LTE modem module, Poor mobile signal at installation site

How to Fix / Troubleshooting

Safety first: Cellular components are low‑voltage but inside a mains enclosure. Only qualified personnel should open the charger.

Steps to try:

  • Check signal: Verify that mobile coverage is adequate at the charger location using a phone on the same network.
  • Reboot the charger: Turn OFF and ON the charger’s breaker to reset the modem.
  • Technician SIM check: A technician can open the unit, reseat the SIM card, and verify that the SIM is active and not PIN‑locked.
  • Replace modem module: If the modem remains offline with a known‑good SIM and signal, replace the 4G/LTE module with a Hager‑approved part.
