Update:
Although device registers with VoWiFi, calls fail immediately when trying to call out. Perhaps "roaming" needs to be enabled, but Telkom works flawlessly
Good luck then. As critical stuff like VoLTE and VoWiFi is not enabled for AirMobile from the start, and Afrihost cannot provide any insight into when it will be enabled.
Yet, Pi by MTN (also virtual mobile network) runs on the same MTN network and has got those 2 features enabled by default...
Perhaps try Pi by MTN, as they support VoLTE & VoWiFi, so that might help to say if you're running into issues with the switch back (4G/LTE > 3G) to receive incoming calls.
This is a thing with Pi by MTN as well. Makes so sense, but I think the worse of them all is Telkom. A while ago, had to get a new eSIM because of this exact same situation, just to be told, they don't have stock of eSIMs :ROFL:
When will this switch/change take place?
And would this be staged per region or FNO? Will both systems run concurrently or one big bang switch?
Really need to know beforehand, as this change is pretty big, and working from home, I'd like to ensure I have an sufficient backup (or potentially...
IPv6 would have been great, but I've never ever been able to get IPv6 working on my Mikrotik with Frogfoot.
In the past, I've provided a TCP dump where it's clear the Mikrotik asks for IPv6 delegation (or whatever it does), but there is just never a response back.
So as now, I can 100% confirm...
