Hello, Jet.

It sounds like the phone might be having issues using the VoLTE services since the 3G service was disabled. You mentioned that you got the phone elsewhere, so it's possible that the phone doesn't have the correct carrier settings on board for using VoLTE on Three.

Doing some searching online, it looks like Sony provides different configurations for phones purchased from different carriers, and for phones purchased from a non carrier store. While looking around, I saw that Sony used to have a software tool for flashing a different carrier version onto their phones.

I'm unsure if that's still a process they are doing, or how to do it, but it might be worth reaching out to Xperia support to see if they have any suggestions on that.

Just to confirm, you tried other network sim cards in the Sony 1 II and they work?

Yes I tried an EE SIM works absoolutely fine ,this current three Sim also works fine in our other phones on three in the household a moto g73,redmi 10 ,and also a much more basic TCL 20 se ,strangely yesterday I was able to call it as I was elsewhere yesterday were the 3g hadn't been turned of despite the Sony being in our home area where it has so can only assume the 3 g network and volte network compatibility being the issue despite it being fully volte compatible and 5g

Hi @Jet69,

Can you please check out the advice on and let me know if the steps there help? You may need a software update, or as the phone was purchased elsewhere you may need to check for a VoLTE/4G calling option and enable this.

If you're no further forwards after checking the advice on the linked article, please let me know.

Thanks,
Jonathan

Hey there, SirMud.

Welcome to the Three Community.

Sounds like a frustrating issue to be having. I posted here before as it's quite a strange issue. I found at the time that Sony were using custom configurations for their Xperia phones sold through different carriers or retailers.
I suspect that these configurations might be the cause of VoLTE not working correctly on some of their older phones. Looking further into it, it looks like Sony have a tool for updating the software and even flashing new firmware onto their devices. I was limited in what I can see because I can't use the software and don't have an Xperia to test, but each device seems to have a list of different firmware files that can be flashed to it, and there are different ones for different carriers.

I won't advise you to go ahead and try that as it's not a process I can guarantee will work. I would however recommend reaching out to Xperia Support to ask about their flashtool, Open Device project, and ask for advice on whether or not they have a firmware that would resolve this issue.

Pete.

Three told me to contact Sony to have them give me new settings, I did but sony said to contact three for new settings because if other network sims can make and receive calls then it's an issue with three.
