    How do I insert a SIM card in the CareHub?

    Last updated 28 July 2026

    The CareHub uses Wi-Fi by default for internet, with a built-in 4G SIM as backup. For households without reliable Wi-Fi but good mobile coverage, the CareHub can run primarily on a SIM card. This article covers how to insert a SIM card if needed. Most households don't need to do this themselves — it's normally handled by Lumin during setup. But occasionally a SIM swap is needed (network change, replacement SIM), and here's how it works.

    Before you start

    • Use a micro-SIM. The CareHub's SIM slot is sized for micro-SIM. If your SIM is a different size, your provider can supply a micro-SIM, or use a SIM adapter.
    • Power off the CareHub first. Press and hold the power button at the back, choose Power Off, and wait for the screen to go dark.
    • Have something thin to hand — the edge of a credit card or a paperclip can help slot the SIM in firmly.

    Inserting the SIM

    1. Look on the back of the CareHub for the SIM card slot. It's clearly marked with a SIM icon and the word "SIM", so you don't need to count slots or memorise positions — just look for the label.
    2. Insert the SIM with the gold-coloured contacts facing out (away from the body of the device).
    3. Push the SIM in until you feel a small click. Use the edge of a credit card if needed to press it in firmly.
    4. Turn the CareHub back on (plug in power; it'll boot automatically).

    Activating the SIM

    Once the SIM is inserted and the device is on:

    1. Press and hold the power button until three options appear.
    2. Tap Settings.
    3. Tap System Settings and enter the PIN 8888.
    4. On the left side, tap More → Mobile networks (or similar, depending on the hardware version).
    5. Make sure mobile data is enabled.
    6. Verify the SIM is recognised — the device should show carrier name and signal strength.

    If it's not working

    • SIM not recognised. Make sure the SIM is correctly inserted (contacts out) and pushed in firmly. Try removing and re-inserting.
    • No signal. The SIM card may not have coverage at your location, or may not be activated by your carrier. Check with the carrier.
    • Wrong PIN. The PIN for System Settings is 8888 by default. If you've changed it and forgotten, contact Lumin Support. If you're not sure or it's still not working, contact Lumin Support — we can walk you through it over the phone, or in some cases handle it remotely.
