There is sim slot in laptop. Just the tray out and put sim in it and insert again. You must have drivers for WWAN and PCI card drivers for this to work. After inserting sim tray in laptop back you system will detect it and open the WWAN software and try to connect.

Sounds like your taxing your system too hard. Perhaps you need to purchase a beefy-er CPU, graphics card, or cooling fan.

There is only blank slot given in this laptop and the hardware is not there according to me. I have the same laptop.

The SIM card is for mobile broadband (wireless internet anywhere you have cellphone service).
Before using Mobile Broadband, you first need to choose a mobile networkoperator (such as Sprint, Verizon, AT&T, T-mobile, etc.) and make sure you are in the coverage area of the network.
After that, you also need:• To activate the Mobile Broadband service through your local mobile network operator. Youwill get a Subscriber Identity Module (SIM) card after activation.

TO ACCESS INTERNET ON YOUR MOBILE YOU SHOULD HAVE

1. GPRS ENABLED DEVICES.
2. WORKING GPRS NETWORK.

FIRST OF OF ALL YOU HAVE TO CALL YOUR SERVICE PROVIDER TO ACTIVATE GPRS ON YOUR SIM CARD (YOUR NAME SUGGEST THAT YOU ARE FROM INDIA SO IF YOU HAVE AIRTEL SIM THEN DIAL *567# OR HAVE TATA DOCOMO SIM THEN DIAL *141# TO ACTIVATE GPRS BY YOURSELF.)
AFTER GPRS ACTIVATION AGAIN CALL CUSTOMER CARE AND ASK THEM TO SEND SETTING ON YOUR DEVICE(IN AIRTEL SEND "MO" TO 543210 FOR TATA DOCOMO SEND "INTERNET" TO 52270)
AFTER RECEIVING SETTING SET THEM AS DEFAULT SETTING.
