If your Reolink 4G camera is offline or disconnected, please follow the step-by-step troubleshooting guide below to help restore the network connection.

Applies to: All 4G cameras.

Step-by-Step Troubleshooting

Step 1: Ensure your Reolink 4G camera is powered on

Restart the camera and observe whether the indicator light near the lens turns on. You can also press the reset button and check if you hear any voice prompts from the camera, indicating that it has power.

If the camera doesn’t seem to have power, please charge it using a DC 5V 2A adapter and observe its connection status again.

Step 2: Check SIM Card Installation

Before performing any further actions, make sure the SIM card is properly inserted into your Reolink 4G camera.

  • Power Off the Camera: Ensure the device is completely powered off before handling the SIM card.

  • Remove and Reinsert the SIM Card: Take out the SIM card, inspect it for dust or damage, and reinsert it carefully into the correct SIM slot based on the user manual. Make sure it is fully pushed in.

  • Power On and Wait: Turn the camera back on and wait 2–3 minutes, allowing the camera enough time to search for and connect to the mobile network.

If your Reolink 4G camera still cannot connect, refer to the following sections based on the SIM card you are using:

Scenario 1: you're using a third-party SIM card (not provided by Reolink)

If you're using a SIM card from another carrier, it's likely that network difficulties stem from compatibility or the mobile data plan.

  • Check carrier compatibility: Not all third-party SIM cards are compatible with Reolink 4G cameras. Please refer to our official compatibility list to ensure your SIM card is supported.

  • Verify your data plan: Ensure your SIM card includes a valid data or IoT plan and is not suspended or unpaid. Some phone-only SIM plans may not work properly with Reolink 4G cameras.

  • Recommended: If your camera comes with a Reolink SIM card, we highly recommend using it for the best experience and hassle-free setup. The Reolink SIM card is specifically designed for Reolink 4G cameras, once inserted and activated, it works immediately—eliminating the need for complex compatibility checks.

Scenario 2: you're using a Reolink SIM card

If you're using a Reolink SIM card, follow the steps below:

  • Make sure the SIM card is activated: Reolink SIM cards must be activated before use. If you haven’t done this yet, please visit our activation page. Here is a detailed guidance for your reference: How to Link Reolink SIM Card to Reolink Account.

  • Check the validity of your data plan: Make sure your SIM card has an active data plan with sufficient remaining data, as an expired or depleted plan can prevent the camera from connecting to the network.

  • Contact Reolink Support: If the SIM card is already activated and properly installed but your camera still won’t connect to the network, the cause may be related to carrier or the SIM card itself. Don’t worry—our support team is here to help!
