Are you trying to add cell service or increase memory? If you are trying to add cell service then you should contact a cell phone vendor. If you are trying to copy data from one device to this one, the format may not work on the tablet.
It sounds like the SD card is either not formatted or is formatted in a way the tablet can not read. There should be some system tools on the tablet that will format the SD card. Also, check to make sure that the lock switch is in the unlocked position.
