What to do if my Doro Cell Phone shows a SIM card error?
- RRebecca DeckerAug 17, 2025
If your Doro Cell Phone displays a SIM card error, check the condition of the SIM card. If it is damaged, contact your service provider. Also, check the installation of the SIM card by removing it and reinstalling it. Ensure the contact surfaces of the SIM card are clean by wiping them with a clean cloth.
