How to Turn Your Android Phone Into a Wi‐Fi Hotspot

1. Check with your carrier. While some services include free mobile hotspot usage on all plans, not all wireless services allow the use of mobile hotspots without paying an extra fee.
 >If your plan does not support mobile hotspots, you will not be able to enable your hotspot
2. Open the Settings menu.
 > You can access this from the Settings app on your Home screen or App Drawer, or by pressing your phone's Menu button and selecting "Settings".
 3. Tap "More" in the "Wireless & networks" section.
4. Tap the "Tethering and portable hotspot" menu.
 >This is typically located in the Wireless & Networks section of the Settings menu.
 >You may need to tap "More..." to find it.
 5. Tap the "Set up Wi-Fi hotspot" option to change your settings.
 >Adjust your hotspot settings. 
 >Before activating your mobile hotspot, you should ensure that it is properly secured and that the SSID (network name) does not contain any personal information.
 >Network SSID - This is the name of the network that will be broadcast. Anyone nearby will be able to see this name, so make sure that there is nothing that can identify you in the name.
 >Security - Unless you're trying to connect old devices that don't support newer security protocols, you should always have this set to WPA2 PSK. Hotspot frequency band - By default this is set to 2.4 GHz. You can usually keep this setting, but you may want to change it to 5 GHz in crowded areas. 5 GHz will lower the range.
 >Password - You should always have a password set, without exception. Make sure that it is strong, but memorable, as you will need to enter it on the devices that you are connecting to the hotspot with
.6. Check the "Portable Wi-Fi hotspot" box to enable the hotspot. Your service plan will be checked to see if you are allowed to create one. 
>If you receive an error, you will need to contact your carrier and inquire about setting up a mobile hotspot on your plan. You may not have access to it unless you spend more money.
 7. Connect to the hotspot on another device. Open the "Connect to network" menu on the device that you want to connect to the hotspot. You should see your new hotspot in the list of available networks.
 >Select it and enter in the password you created. Your device will now connect to the hotspot. 
>See this guide for detailed instructions for a variety of different devices. 
8. Tap the "Data usage" option in the Wireless & Networks section of the Settings menu to monitor your data usage. Using a hotspot will typically burn through your allotted data much quicker than simply using your phone to browse the internet. Be prepared to see your usage increase when using your hotspot.
