Hi steelmalc
Thanks for replying, that's interesting, I also find that the Wifi Calling will work if I travel to friend/family but eventually (at what point is a mystery and very difficult to pin down) I find that the Wifi Calling and VoLTE will always eventually stop working and the only way to restore is to reboot the phone.
This will happen every day if I travel, but if I stay at home both services will work fine for days.
Its very frustrating
Can I ask, is your phone running the same software versions as mine?
*Edit* I also notice from your post on page 1 of this thread that you also have to "VoLTE calls SIM 1" option in Network settings, my phone does not have this option even though VoLTE works most of the time.
Yer seems to be the same ..don't know if it's because mine is unlocked (SIMFREE)from Samsung you could look under connections /mobile networks/then access point names mine say contract wap don't know if it will do anything but could be worth a look
Ahhh, I think the difference could be that yours is direct from Samsung and so doesn't have the Voda "Variant" firmware.
That would also explain why you also have the VoLTE menu option and mine doesn't.
Its Ironic as the reason I purchased mine though Voda was that I specifically wanted to make sure the Wifi Calling and VoLTE worked.
This makes me more convinced its a Voda issue in their "Variant" firmware.
I assume yours must say different in the "Service provider software version" under About Phone/Software information.
It's not much different apart from the service provider software version so yer that could be something to do with it to be honest iv never liked buying from a provider was never keen on the software they install on them so I always try and buy direct ie Samsung
