To do so, perform the steps listed below.

1. Open your iPhone, tap Settings, and then tap General
2. Select Personal Hotspot (if this option is not present, contact your network provider. By paying an extra fee you most probably will be able to add tethering)
3. Turn Personal Hotspot on (by default this option is switched off)
4. Enter a name and password for the mobile hotspot

Next, open your iPad or laptop and select the mobile hotspot just created.
