If ur Nokia phone doesn't have Wi-Fi can u have it installed?

Question

If so, where do they do this?

Answer 1

Practically not possible now but may be possible in the future.

You can do a research on the subject and make it work.

First you have to program a symbian application that will support the wi fi device.

Then you can connect the device through the DKU port and make it work

Answer 2

Have you ever heard of some phone in which you can make hardware additions? Like there would be space there to plug in a WLAN card ...
