Step 3: Toggle Cellular Data On

Find the switch next to ‘Cellular Data’ at the top of the screen and toggle it to the green ‘on’ position.

By flipping this switch, you’re giving your iPhone the green light to use cellular data. It’s like saying, “Go ahead, iPhone, jump onto that mobile network and bring me the internet!”

After you’ve completed these steps, your iPhone will connect to your mobile network and start using cellular data. This means you can browse the internet, check emails, and use apps that require a data connection even when you’re not connected to Wi-Fi. It’s a game-changer for staying connected on the go!
