From Voda to id on a Sony Xperia XQ-AU51

Hi, the above phone is not on the list of compatible phones. WhatsApp works, internet works, navigation works, phone receives  a signal. However I cannot ring out or receive calls or messages. When I scroll down the settings to “About Phone” under phone number it says Unknown, and I can’t see a way of putting the number in. In  network and Internet, under calls and SMS it says id, under sims it says id. I took my Vodafone number with me, I unlocked the phone with a Vodafone provided code. Not sure what to do next? Thanks Wixxy.
