Hey, yes, sorry, i messed up the version numbers. I was talking about ii and iii.
Right now i have two sim cards, one t-mobile and one simOn mobile (both german 900 MHZ D net).
If i insert them in my Xperia 10 ii (2) i get an IPV4 address assigned over mobile network (see the attachments with “ii” in their names if you like). Software version on ii right now is 4.4.0.68 but i’m 97.5% sure that PV4 assignment worked on all previous versions as well.
On my Xperia 10 iii (3) i get no (!) IPV4 address assigned over mobile network (see the attachments with “iii” in their names if you like) (version 4.4.0.72 but didn’t work on 4.4.0.68 (and 4.4.0.64) neither).
On my Xperia XA2 i’m quite sure i got IPV4 addresses assigned.
So for me it’s evident that only the Xperia 10 iii (3) is missing an IPV4 address assignment.
P.S.: if i got it right at the passed IRC meeting there will be a new software version in January and it will include some rework on connection establishing / switching. Maybe this topic gets fixed by this update, too. But i’m not sure if i’ve understood it right.
