It depends on which model of the Galaxy Tab 4 you have. The unlocked Galaxy Tab 4 3G is compatible with the Straight Talk GSM network and has a SIM card slot. There is a Wi-fi only model which will only talk to a cellular network through a hot-spot device.

I hope this helps.

Support - Wi-Fi Tabs GT-P5113 ' Samsung Galaxy Tab

• First, tap on your Settings app (or icon if you have a shortcut on one of your home screens). It's the one that looks like a cog or gear. This will bring up the Settings menu.
• On your Settings menu, tap on Wireless and network.
• You should now see a list of wireless-related menus. Tap on the Flight mode - also generally known as Airplane mode - to disable all wireless connections. You'll know it's working because you get an airplane icon on your notifications bar.
• Great, now you won't be getting any incoming calls. But wait! Now your Wi-Fi connection isn't working, either. Nice going, Jason, you regular Einstein. Hold on your horses, though, because we're not done yet. On that same wireless submenu, tap on Wi-Fi settings.
• Click the option to Turn on Wi-Fi.
• Look at your notification bar on your home screen again. You'll still have the airplane icon on, indicating that you won't get any calls. But you will also start seeing a Wi-Fi signal icon. Voila! Now you can connect to a Wi-Fi enabled router or hot spot without worrying about getting roaming charges.

It's a good idea to access Wi-Fi whenever possible to avoid data charges. After you've activated the Android tablet's Wi-Fi radio, you can connect to an available wireless network. Obey these steps:

1. Open the Settings app.
2. Choose Wi-Fi.On some Samsung tablets, you find the Wi-Fi item on the Connections tab. Choose Wi-Fi to view a list of available Wi-Fi networks on the right side of the screen. Otherwise, the list shows up full screen.
   
3. Choose a wireless network from the list.When no wireless networks are listed, you're sort of out of luck regarding Wi-Fi access from your current location.
4. If prompted, type the network password.
   Touch the Show Password check box so that you can see what you're typing; some of those network passwords can be long.
5. Touch the Connect button.
   The network is connected immediately. If not, try the password again.

When the tablet is connected to a wireless network, you see the Wi-Fi Connected status icon. This icon indicates that the tablet's Wi-Fi is on, connected, and communicating with a Wi-Fi network.
Some wireless networks don't broadcast their names, which adds security but also makes connecting more difficult. In those cases, touch the Add icon. This icon might also be labeled Add Wi-Fi or Manually Connect. To make the connection, type the network name, or SSID, and choose the type of security.
You also need the password, if one is used. You can obtain this information from the girl with the pink hair who sold you coffee or from whoever is in charge of the wireless network at your location.

• Not every wireless network has a password. Still:
• Be careful when connecting to a non-password-protected network. It's possible that the Bad Guys can monitor such a network, stealing passwords and other information.
• Some public networks are open to anyone, but you have to use the web browser app to find a login web page that lets you access the network: Simply browse to any page on the Internet, and the login web page shows up.
• The Android tablet automatically remembers every Wi-Fi network it has ever been connected to and automatically reconnects upon finding the same network again.
• To disconnect from a Wi-Fi network, simply turn off Wi-Fi.
• Use Wi-Fi whenever you plan to remain in one location for a while. Unlike a mobile data network, a Wi-Fi network's broadcast signal has a limited range. If you wander too far away, your tablet loses the signal and is disconnected.

Solution 1.Check wireless connection.
The first step of diagnosis have to any other device connected to the same network, ensure the wireless connection is working fine, or verify the settings of your wireless router to correct it.

Save changes and exit all the screens. Your Wi-Fi will never get disconnected again due to this policy.

3.Check signal strength of wireless connection.
The performance of a wireless network connection depends in part on signal strength.
You have to connect the Wireless network where the signal strength is strong.
Check Wireless network signal strength icons in notification bar.

4.Try to turn off/on Wi-Fi on the device.
First to turn off Wi-Fi, [Settings]>>[Wi-Fi] >>[turn Wi-Fi to off].
And then to turn on Wi-Fi, [Settings]>>[Wi-Fi]>>[turn Wi-Fi to on].

5.Try to forget network on the device.

[Settings]>>[Wi-Fi]>>Press & hold your[Net Work Name(SSID)]for 2 seconds.
>>Select[Forget Network]>>Re-Connect your wireless networks if it's disconnected.

7.Make sure your firmware is up-to-date.
>>Select[Settings]>>[About tablet]>>[System Firmware Update]>>[Check Update].

8.Try to reset your device.
