Our mobile phones connect to the internet using 3G, 4G or 5G called ‘Mobile data’. To use a phone as a hub to connect to the internet turn on ‘Hotspot’ then sign in to that WiFi network. On an iPhone go to Settings ❯ Personal Hotspot – ON. On Android, Settings ❯ Connections ❯ Mobile Hotspot and Tethering ON (tap to set a password and see instructions)
