Is there a place for a sim card?
There is a slot for a micro sd card, but I do not see a slot for a sim. Do I need to take the back off to access it?
The third generation of the Samsung Galaxy tablet with a 7-in. screen announced on June 24, 2013. Repair of this device requires screwdrivers and prying tools. The device is available in white or gold brown with 8, 16, or 32 GB of storage, and includes a microSD slot that can hold up to an additional 64 GB of memory.
If your tablet supports it the sim card will be located on the same side of the tablet as the sd slot however not all tablets are made to support a sim card . This video shows how to change it out if its supported
Hope this helps
