Welcome to Vodafone Community
Friend of mine just bought a phone from you : VODAFONE N9 LITE but there is no polish language inside, there is anything you are planing to do with that or it's impossible. I scroll few forums but phone is brand new and there is nothing written about it.
Thanks in advance
This would depend on the Android software on the handset.
Please keep an eye for Android updates for the addition of the language option.
