How do I format my wildgame camera sim card? - Wildgame Innovations 10MP WIFI Digital X10

Usually you have to format it inside the unit, as the unit has its own non-standard filing system. However, perhaps you have the wrong type of card?

IMPORTANT: Make sure the camera is powered off before removing or installing an SD card. If you are using an SD card from other cameras, please make sure to format the SD card in your computer prior to use in your camera. New cards are ok to use straight from the package.

Check if defaults to own internal memory, not the SD card.
Many have a small internal memory for when no SD card is inserted.
It'll be under settings options

Was the card formatted using the FTP protocol? It has to be in order for it to work.

Here's a PDF of it:

If you have a laptop that can read SD cards, or an USB adapter to put it in your computer. Then right click on the SD card and click on format.

I can think of a few possible issues:
1. SD card not formatted (format it in the camera)
2. SD card bad. try another one.
3. SD card bigger than camera can handle.

It's not the camera. Look at your memory card. SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

It's not the camera but the memory card. SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

try formatting to FAT32 or NTFS

It's not the camera, it's the memory card. SD/SDHC cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.
