Why ?

whats happens when you try

what are you doing to initiate the process

Do have WiFi and Bluetooth enabled

Does your Mobile operator support tethering or do they require payment for activation and data usage

Many questions need YOU to tell us about before we can help as we are humans and are not telepathic!
