If your Doro Cell Phone displays a SIM card error, first check the installation of the SIM card by removing it and reinstalling it. Also, inspect the condition of the SIM card. If it is damaged, contact your service provider. Finally, wipe the contact surfaces of the SIM card with a clean cloth, as it may be dirty or damp.
