To make your phone a hotspot for free, follow these steps: 1. Open the Settings app on your mobile phone. 2. Look for the "Hotspot" or "Mobile Hotspot" option and tap on it. 3. Enable the hotspot feature by toggling the switch to the "On" position. 4. Configure the hotspot settings, such as the network name (SSID) and password, if necessary. 5. Once the hotspot is active, other devices can connect to it by searching for available Wi-Fi networks and selecting the network name (SSID) of your phone's hotspot. They will need to enter the password you set, if applicable. Please note that using your phone as a hotspot may consume mobile data from your cellular plan, so ensure that you have sufficient data allowance or an unlimited data plan. Additionally, check with your mobile service provider to ensure that tethering/hotspot functionality is included in your plan without any additional charges.
