I’ve got a SOLUTION!
My logic was this: if Iliad is the only one in Italy that works out of the box, what is the reason? Of course you know why, it’s the only italian provider that still doesn’t have VoLte enabled, so on our SFOS devices it just doesn’t get registered or whatever, so data works.
So, I’ve done this: firstly I checked on my account area of WINDTRE and saw VOLTE service enabled since 2022 when I used an iPhone 7. WINDTRE has a list of supported devices, none SONY devices there.
So, I’ve called them and asked to disable VOLTE on my line… waited some minutes then ok. all done.
So, next… just wait!
When your line gets VOLTE no more as a feature, you know, you’ll have your data working on Xperia 10 III on SFOS!!
Currently enjoying on 4.5.0.24 with both 3g and 4g! Edit: seems to work better on 3G.
So the SOLUTION to this, is call your provider, Vodafone (need to check), WINDTRE (they can do this), TIM or PosteMobile etc and ask them to DISABLE volte. You’ll have it!
