I gave up after spending hours with Amaysim / Optus help desks, who wanted to reset APN settings etc. All to no avail.
Purchased a Telstra Sim and ported account over from Amaysim.
MMS works with Telstra.
Anyone else managed to get the Android OS version upgraded? I can't seem to find it online or via OTA?
WW_220.127.116.11 just installed itself. Seems that this fixed it!
Hey Guys same here finally ASUS has got their shit together & their latest release of 18.104.22.168 has fixed the MMS but no sign of VoLTE yet for AU ASUS Zenfone 8.
Only just came back to this. The version I have is 22.214.171.124. MMS fine but no VoLTE.
No VOLTE but HD voice is working now (Orange PL)
We fixed the MMS issue and enabled HD Voice in this version.
Any update on when VoLTE will be added to Zenfone 8?
I'm having the same issue with my ZS590KS on both ASUS's latest Android 11 and it's Android 12 Beta 1. I've tried Signal, Android Messages and Microsoft's SMS Organizer. I'm on Mint Mobile (TMO) in NA. Using Mint's APN. Very frustrating, no MMS problems with iOS...
