Why Do People Use Mobile Hotspot?

Mobile hotspot is useful in many real-life situations where regular Wi-Fi is not available or not safe.

Attending online meetings during Wi-Fi outages
Sharing internet in emergencies
Connecting devices without SIM cards
Using private internet instead of public Wi-Fi

How Does a Mobile Hotspot Work?

When hotspot is turned on, your phone uses its mobile network (4G or 5G) to receive internet data. It then converts that connection into a private Wi-Fi network.

Other devices connect using a hotspot name and password. All their internet traffic passes through your phone.
