I have downloaded nokia PC suite.but my Pc is not recognising the data cable.
Check via another USB port and see if it works. If that does not help, switch on the bluetooth of the phone, go to PC Suite and try connecting via bluetooth (if your pc is also bluetooth enabled). Also check if other devices are working when connected via the USB. Otherwise you will have to download and install Nokia PC Suite again and check if you have compatible software for 3500. I have had problems with PC Suite before and after fiddling with connectivity, I tried to reinstall it and it worked. This was for 6600. I used the CD that was given in the box. Hope this helps.
