Many Android phones allow you to activate Wi-Fi by swiping down on the home screen and tapping the hotspot symbol.
For some, you will need to first enter the hotspot settings on your phone. Your steps will vary depending on what model of phone you have, but will be similar to this:
• You can access the Mobile Hotspot tab by going to Settings > Connections > Mobile Hotspot and Tethering > Mobile Hotspot.
• Tap to turn it on or off.
• If necessary, you can tap Password to change the password.
