If your card is very thin (<0,7mm) it can have problems making contact properly when inserted. If you put a piece of tape on the logo-side to make it 0.75-0.8mm thick, it will sit better in the slot and make better contact.

Sadly there is a lot of difference between the thickness of cards from different manufactorers. I have seen from 0.65 to 0.82 mm thickness.

There is also a small feathering spring on the slot itself that can be bent down to make the card make better contact:

(scroll down, first note)

SD card specification states operating temp from -25C to 80C
