Make sure that your mobile phone is connected to a cellular network. On your mobile phone, open the settings app. Tap on "Network & internet" or "Connections". Tap on "Tethering & portable hotspot" or "Mobile hotspot & tethering". Tap on "Wi-Fi hotspot". Enter a name and password for your hotspot. Tap on "Save". On the other device that you want to connect to your hotspot, open the Wi-Fi settings. Select your mobile phone's hotspot from the list of available networks. Enter the password for your hotspot. Tap on "Connect". 🤷‍♂🤷‍♂
