You can also look around the sides of the tablet or behind its battery for any slot that a SIM card might fit in. It’s a small slot only a little larger than that of a memory card, and is very easy to find.
the first is by purchasing a prepaid type SIM from your local gadget store. You can get these SIMs for under $5, depending on the provider it’s from. You also don’t have to pay any monthly bill, just top-up from your local store or carrier outlet before you use it. The second way is by getting a postpaid SIM directly from a mobile carrier. Unlike prepaid SIMs, you can get a postpaid SIM card for free, but you have to pay a monthly phone bill to keep it working.
For tablets with the SIM slot located along the sides, you no longer need to turn off the device first before you put the SIM card in. For the other models, switching off your tablet may be necessary before inserting the SIM card. After inserting the SIM card, you should see the signal icon on the upper right-hand corner of the screen go up, telling you that it’s now connected and receiving signals from the SIM card provider.
To end the call, simply tap the red phone icon and the call should terminate at once, leading you back to the home screen.
Tap the “Recipient” field found at the top of the app screen and type in the phone number where you want to send the message to. If you already have contacts saved on your Galaxy Tab, suggested names will appear as you type in the number.
Enable mobile data. Open the notification tray by sliding your fingers from top to bottom of the tab’s screen. Once the notification tray has been expanded, tap the “Mobile Data” quick setting button (the arrows point up and down) found on the upper portion of the tray to enable this feature. Start surfing. Tap the “Internet” application from the home screen to open the tablet’s native web browser. Type in the address of the website you want to visit and press the “Go” button on the keyboard to start surfing.
