MTN status on eSIM, VoLTE (iPhone) and WifiCalling

Your home ISP should not matter though?
:unsure:
Point of it is that it should work as long as you have an active WiFi connection on the phone even overseas , at least on our vodacom phones its working that way

Theoretically yes but in practise no.
On vumatel-cellc based WiFi I can connect to MTN VoWifi.
On vumatel-websquad based wifi I can't connect to MTN VoWifi but I can connect to cellc VoWifi no problem on both networks.
All speculation but I think MTN are opening it to various networks slowly and steadily, but i have no idea what their criteria or reasoning for it is.
Earlier in the thread, another user said they couldn't access it on rain wifi for a period and then it started working.
So I'm trying to establish which ISP's are working and which ones aren't.

Yip I agree it shouldn't as it needs to work overseas but for some reason it does.

I wonder if it might be a network traffic type issue?
like your ISP or even on your router you needs to ensure a certain types of traffic is allowed.
Open NAT that sort of thing

I've tested in the following manner:

Telkom via Hotspot and lte router. Cell C vowifi works.

Telkom via Hotspot and lte router MTN doesn't work.

Rain on the same lte router Cell c and MTN works.

That is possible and is something I considered, but the anecdotal evidence from myself, @Sayf777 and tector lead me to believe otherwise.
I have a dual SIM phone and my cellc VoWifi is working on my home network, which isn't enough to guarantee it to work but shows that VoWifi is possible to some degree on my router and isp. Sim1 is MTN and sim2 is cellc.

I have reached out to WebSquad and they have reached out to MTN regarding it but I think until MTN officially have a product page for vowifi on their website, it's all just a waiting game.
They could probably make the argument that VoWifi isn't needed overseas at the moment because of international travel ban, etc, that there would be such a low demand of people needing it at the moment.
 
Here is cell c ISP over vumatel fibre where both MTN and cell c Sims work on VoWifi.

ok so the other day during load shedding Vumatel went down (power failure on their side strangely enough :ROFL: ) MTN signal in my area is bad enough normally but non existent when power is out, so i pulled out my Mifi device with a standard bank sim (i think it works off Cell c) and literally as her phone(A51) connected my Daughter goes Hey my phone is showing Vowifi now.

And all i can think is why are MTN systems so bloody complicated.

I have no idea how the technical side works but it doesn't make sense to me.

For interest sake, what csc number is that A51?

I see you referred to two A51s above, one XFA and one XFV.

Thanks, some more anecdotal evidence that not all networks are allowed.
Who is your ISP on vumatel?

No idea as well and as soon as my home internet came back the Vowifi signal went away

Mind the speed
but this does not make sense to me - wifes vodacom sim/phone vowifi on the same ISP
and logically at least to me a fibre network should have better chance of working on vowifi then a Mobile one (competitor network to boot)

Managed to test an XFA Galaxy A51,
All network's volte (ex cell c (doesn't have) and vowifi work on it.

Cell c, telkom and MTN have an always on vowifi and Vodacom have it active in bad signal (since Samsung doesn't have a wifi preferred setting for wifi calling).

this VOwifi on our networks is giving me a headache

ok so i have a XFV Note 10 lite with an MTN sim (so vodacom phone with MTN Sim)
On my home network (MTS on vumatel) Vowifi doesn't work - but tethering via mifi device to my Standard Bank sim (cell c) vowifi works. - same Standard Bank sim tethered to the Vodacom sim on the A51 vowifi doesn't work.
Also tried it on Telkom ISP on Openserve same MTN doesn't work Vodacom does.

I have no words :ROFL:

I stand to be corrected, but I think someone mentioned that vodacom vowifi only works when the vodacom signal is poor. So chances are that when the vodacom sim didnt have vowifi, there was good vodacom signal. But I dont have too much experience outside of MTN and Cell C vowifi.

This is correct for samsungs since it doesn't have a WiFi preferred option under WiFi calling settings.
