Neither Nokia nor a Nokia reseller will replace/exchange models, as far as I know.

A network operator (carrier) might give you a new/different model if/when you make or renew a contract with them.

Otherwise, sell the old one and then buy a new one with the money you get (+ whatever extra you need). You may need to wait with the selling, if you don't have the difference yet, and need to save up for that.

Nokia does not offer any exchange of its devices as far as I know. All you can do is to sell your phone and add an extra amount to get yourself a new phone.
