missing watsapp contacts on new phone with same sim i changed my sim from my old phone(nokia n8) to a new phone(samsung GT-S6310L)

on my new phone....i am not seeing few 

numbers of my friends in the watsapp contact list.how can i get or restore their 

numbers?
Transfering the sim does NOT transfer the contacts as well.

You should try using bluetooth to transfer your contacts between the two phones, I believe NOKIA has a built in feature for that in their Symbian Models.
