- Make sure that you have correctly inserted the SIM card
IMPORTANT NOTE – Do not insert the SD card to the SIM slot. This may damage the SIM card reader contacts and the SIM card will not be able to be read. The device will need to be returned to the Service centre.
- If correctly fitted and the message is still displayed, please clean the contacts of the SIM card using a dry cloth
- If still unrecognised, please call your Network Provider to ensure the SIM card has been enabled or to check if they have any further instructions
