I am looking at switching myself and my wife over to ID Mobile. I have a sim free Sony Xperia 5III (O2 sim card), my wife has a sim free Sony Xperia 5IV (Vodafone sim card).
Whilst my phone has VoLTE enabled and working, Vodafone are disabling the feature on my wife's phone (my sim card works in her phone, VoLTE appears in the settings).
Would both phones get VoLTE if we switch to ID Mobile sim cards?
