So I have an interesting situation.
Both partner and I have same iPhone and we were on Telstra pre-paid with Visual Voicemail.
Switched to More, I only have regular Voicemail yet partner still have VV.
More says that don't have VV yet its working on partner's phone.. we've tested and confirm the number have ported across.
Any ideas….???
I have no idea how it works, as I recently changed from Telstra to Belong and ran into the same issue. I wrote it off as a learnt lesson, as Belong state VV does not work. And I received Voicemails the old-fashioned way for a few days, but then randomly received one in VV style. It's weird.
