Can I make a phone call and send a short message on my laptop when I surf the Internet with a wireless network card?

Yes, you must install a network card driver to access the Internet with the network card. There will be a small software on the desktop to control the wireless network card to access the Internet. There are many options in that software, including the option of receiving calls and sending short messages. The wireless network card has an earphone socket, so you can receive calls and send short messages by plugging in the earphone of the wireless network card. Just like a daily mobile phone, you can receive calls from others. I'm using this wireless network card now, the EDGE network card of China Mobile.
