Our Samsung B.A with extraordinary technical knowledge failed to mention one of the very basic thing for VoWifi to work and I'm surprised that no one bothered to question him/her for posting a sponsored dumb post.
For VoWii to work you need a supported phone + some signal strength of supported carrier + supported wifi connection. So even you have a supported phone and your ph is connected to supported wifi but the moment your phone loses connection to mobile tower it simply doesn't work.
So VoWifi helps in situation where there is poor signal but not those places where phone gets frequently disconnected from cell tower due to poor signal.
Shame on Samsung, releasing buggy software where phones are crashing randomly, apps are crashing after android 10 update and they are promoting dumb post.
Samsung focus on what you really need to focus or users will force you to get lost like other brands.
buggy software?and phones crashing i have many samsung smartphones from j7 s8 s8+ s9+ s10lite s10+ s7 edge even m30 m20,one of my friend also has the note 10+......none of them are crashing and neither did i find any bugs in the software....and for apps crashing it isnt necessarily a problem with samsungs software....poor app construction also can cause that
