GPRS Connection Problem

[sarpras]

I connect internet using cell phone (Nokia 3110 Classic). I use Bluetooth for connect computer to cell phone. I use Airtel, unlimited internet facility (GPRS). I registered Airtel GPRS package that provide unlimited net connection for computer.

My problem is, my cell phone clearly connect with computer through Bluetooth, but I connect internet, I get below error

"Registering your computer on the network
Error 734: The PPP link control protocol was terminated."

My cell phone also display
Subscribe data packet first

But, I easy browse internet on cell phone using same package. I not get
"Subscribe data packet first” error.

My computer clearly connect internet using other Dial up connection (land phone).

Please help me.

If I use new data cable or new Bluetooth, Problem is solved?
