We need to rule out a problem with the card or the phone.

Do you have a card reader or another phone you can use to check the card? Can you read it in a reader/another phone?

What happens if you try and boot the phone up without a card in or another card?

It might be better if you registered an account so we can talk you through some potential fixes!
