I am having the most peculiar problem with my Samsung Note 9 running One UI 2.5.
I cannot pinpoint as to when this started occurring but i am having major issues with Wi-Fi calling on the device. I am on the three network and on my home Wi-Fi network sometimes it switches over to Wi-Fi calling however not always (I presume this is dependent on cellular signal strength). The issue arises however when i am at work.
I work in a basement in a large commercial office building and the building has 3x networks (2 of which are password protected and 1 which is free access). When in the basement i have no cellular signal whatsoever however my phone is still showing 4x bars. It will not however connect to Wi-Fi calling under any circumstances (it is set to switched on).
The Wi-Fi network definitely supports Wi-Fi calling as I have a Note 10 device as my work phone running on EE connected to exactly the same network and is connected to Wi-Fi calling. I have also inserted the EE sim into my Note 9 and it then connects to Wi-Fi calling so it doesn't appear to be a device issue. I have also put the Three sim into the Note 10 however as i presume the device is locked to EE it will not connect to a cellular network to test this the other way round.
I have spoken to both Samsung and Three who both are not able to resolve this. Three have even sent out a new sim just incase and this has not worked. I have also spoken to the person who manages the Wi-Fi networks at work and he has looked into this and cant see any block or reason why it wouldn't be working so am at a total loss.
If anyone can help it would be greatly appreciated as is causing major issues for me when i cant receive any calls during the day whilst at work.
Hey there Ollie120!
Sorry to hear about the issues you're facing.
Can you go to the Wi-Fi calling settings, and can you set the option to prefer Wi-Fi instead of Mobile networks? Then test your phone down in your basement again - hopefully forcing your phone to use Wi-Fi should fix the problem.
Hope this helps,
I've tried it but in the Wi-Fi calling setting I only have the option to switch it on or off.
Hey, unfortunately not it takes me straight back tot he same screen.
The strange thing is that on the note 10 I am using also, if I go into "mobile networks" in my setting, it has the option for VoLTE whereas on the note 9 it isn't there.
Thanks for your help anyway.
