WiFi Calling now unrelaible following Android update

[Llan82]

After the withrawl of the fantastic suresignal box I bought a Samsung A52s in order to use Wifi calling.  Although I really resented having to get a new phone to be able to make and take calls (even though I live 2 miles from a motorway I am in a really weak signal area) the wifi calling has worked well.  Then my phone updated to Andoid 13 and wifi calling ceased to work.  I contacted vodafone and they sent a new config setting to the phone over the network and asked me to restart the phone.  Sure enough it worked for a while but as soon as the phone gets a faint sniff of a 2/4G signal it decides to dump the Wifi calling link.  When the 2/4G signal drops totally and the phone shows  "Network is not availble" Wifi calling does not re-establish itself unless I restart the phone.  I have tried forcing wifi calling to be invoked by putting the phone into airplane mode and then selecting wifi and wifi calling but it only works sometimes.  My son has a Samsung A33 on Android 12 and wifi calling seems to work faultlessely (so far).   ; I fear that the handset provider will blame the network and vice versa.  I have read that EE and Three are much better at supporting wifi calling and am considering moving to them.  Has anybody had the same experience?  Is there a proper fix for this as the intermittent nature of this is a real pain.  Do vodafone actually pick up these issues and fix them via this community?

Were the phone's supplied by Samsung directly or via the Vodafone Network @Llan82 

I ask as a branded phone i.e supplied by a network can have a slightly different flavour of software including a different csc.

Vodafone are meant to pre test software for their branded phone's before allowing Samsung to push out updates.

Vodafone UK Firmware-Explained. 

Have you tried both turning off Wi-Fi Calling in your myvodaphone and in your phone's settings and then reset the service back up.

You could also send feedback via your Samsung Members App.

Thanks for your response

-I bought it from Carphone warehouse as disinclined to buy it from Vodafone after they pulled the plug on Suresignal box.  I was shown the exact model working on vodafone (the manager put a vodafone sim in the display model in the shop and then demoed wifi calling eve though it was not on the vodafone list!) so i am distrustful of vodafone and feel that this is just them locking you in.   All worked well until Android 13 came along! 

- I have checked the myvodafone app - Wifi calling is enabled.  Phone settings likewise.  

- I may try posting on Samsung community.

Your model of phone is listed on the Vodafone wi-fi-calling list however they do also state " All these phones support both WiFi and 4G Calling when bought from us. Please note that phones bought from other UK network providers and third parties are unlikely to support Vodafone WiFi and 4G Calling – with the exception of iPhones, which should work regardless. "

That said we have seen phone's still work typically by asking the Vodafone Customer Services Agent to send the files via an Over The Air Configuration.

This is a Network Driven feature out of Samsungs hands unfortunately.

Samsung could possibly state the phone wasn't supplied by them and that it's a network driven feature thus out of their control. 

Carphone Warehouse have supplied the phone but they can't make Wi-Fi calling work.

In your about phone section under software information what are the three alphabetical letters at the end of the information in Service Provider Software Version ?

Mine is EUX

Yes I am aware of vodafones defensive "lock-in" lines.  Fact is that it seems they are quite poor at supporting Wifi calling unlike other network operators. See this:  Best WiFi calling networks: all the providers with it in the UK (simsherpa.com).

Given this and the fact that they dumped the sure signal box a year ago (which is why I went to Vodafone in the first place!) means that I really cant be bothered to deal with vodafone anymore.  I am paying well over the odds so will probably try elsewhere.  I sense that I am not the only one.  

WRT Service provider SW version - I have the following:

BTU/BTU, BTU/EUX/BTU

What does it mean?

When Vodafone sent some config setting to my phone last week to try and resolve the issue - is it this that they changed?
