How to troubleshoot a SIM card error message

Reboot your device by powering it off and then back on. Check if this fixes the SIM card error message.

The SIM could be out of place. If you've recently dropped, bumped, or opened your device, the SIM card may need to be adjusted to make sure it is positioned correctly.

Sometimes dust can get between the SIM and your device, causing communication issues. Clean the gold-coloured connectors on the back of the SIM card with a clean, lint-free cloth.

If you bought a new SIM card, it might not be properly activated. Visit our online Activate your Device page and follow the onscreen instructions to activate your SIM card.

If all of the above steps fail, your SIM card may be defective and require replacing. You can purchase a new SIM card at your nearest C Spire store.
