This depends on your carrier and plan. Many modern plans allow tethering at no extra cost, drawing from your regular data allowance. Some prepaid or budget plans throttle or block tethering entirely, or require a separate add-on package.

Tethering / Hotspot: Definition & explanation
In a nutshell
Tethering means sharing a smartphone's mobile data connection with other devices. Using a Wi-Fi hotspot, USB cable, or Bluetooth, laptops, tablets, or other phones can access the internet through the phone.
How does Tethering / Hotspot work?
Tethering turns your smartphone into a mobile router. The device uses its SIM card and data connection to share internet access with other devices. The most common method is the Wi-Fi hotspot: the phone creates its own password-protected wireless network that other devices can join. Alternatively, tethering works via USB cable (more stable, faster connection, simultaneous charging) or Bluetooth (more power-efficient but slower). This feature is typically activated in network settings under 'Personal Hotspot' or 'Tethering'. It's important that your mobile plan includes enough data, since all connected devices draw from the same data pool. Some carriers throttle or charge extra for tethering, especially with older or prepaid plans. Modern smartphones often support multiple simultaneous connections and display data usage per device. Tethering is particularly useful on the go when no Wi-Fi is available—on trains, in cafés without network access, or during business trips. It's also handy as a backup when home internet fails. A Wi-Fi hotspot typically has a range of 10-15 meters.

Frequently asked questions
USB tethering offers the most stable and fastest connection, plus it charges your phone simultaneously. Wi-Fi hotspot is most flexible for multiple devices but uses more battery. Bluetooth suits power-efficient connections with low data needs.
Use a strong, unique password instead of the default setting. Enable WPA2 or WPA3 encryption in hotspot settings and change the network name periodically. Turn off the hotspot when not in use.
