SD cards and my phone
Some Windows Phones have a Secure Digital (SD) card that's used to expand the amount of storage space on the phone. If your phone has one, it's in an SD card slot underneath the battery cover on the back of your phone.
Windows Phone uses a special high–performance SD card that works differently than SD cards in other devices. When your phone is built and first set up, its internal storage and SD card are combined and recognized as one storage system.
You should not remove the SD card in your phone or replace it with a new one because your Windows Phone won't work properly. Existing data on the phone may be lost, and that SD card can't be used in other devices or Windows Phones.
