yeah, that’s what I thought. It was kind of opt in in the past, not so anymore it seems.
Funny that when their support called, and I said I see my phone has 4G he did not mention anything about volte, even though I insisted my phone shows 4G in the settings. Well he offered me 100CHF as a gift to buy something from their shop, so I did not complain. Too bad they don’t have any Sony’s int their shop I could put SF on.
