4g calling, VoLTE icon not displayed?

I have a Galaxy S9+, 4g calling is enabled in my account and enabled in the mobile settings on the phone itself. The O2 coverage map indicates I'm in a good area where 4G calling is enabled. However I'm never seeing the VoLTE icon in the status bar. Friend of mine with a Galaxy (on EE) see's the VoLTE icon all the time with VoLTE calling active.

 

I think that 'Voice over LTE' and '4G calling' are the same thing, so why do I never see the VoLTE icon? Does anyone else enabled for 4G calling see the VoLTE icon?  

 

Thanks.

It all depends on the firmware on your phone. You may just see 4G displayed when on a call.

Re: 4g calling, VoLTE icon not displayed?

Thanks, I'm sure I'm on the latest firmware. From what I've read the VoLTE icon should be displayed if the phone is VoLTE capable and enabled (i.e. on all the time regardless of whether or not a call is in progress).  That's why I wanted to know if other O2 users with 4G calling enabled see the VoLTE icon or not...

Re: 4g calling, VoLTE icon not displayed?

Are you using an o2 variant or Sim Free.. 

 

What i have noticed is that the VOL LTE icon doesnt always appear on devices.

Are you seeing 4G displayed when on a call or only 3G?

I guess on generic firmware it is enabled and for network devices, it will be the choice of the network.

Re: 4g calling, VoLTE icon not displayed?

This is an O2 phone so O2 firmware. During a call (and I've tested this from my friends phone where the VoLTE icon is on) on my phone the 4g icon *always* drops to H or H+...hence my initial query as I thought with 4G calling the phone should maintain the 4G connection. So (despite 4G calling on my account and the 4g toggle enabled on the phone) I don't think 4G calling is working for me, which is why I was interesting in whether or the not the VoLTE icon shows on other O2 phones...

It's not working, hence the reason I asked if it showed 4g or 3g in a call.
You need to give customer services a call to find out why?

If you previously had an iPhone, you might still be on iData which will prevent certain features working on an Android device.
Also, what is your CSC ?

Re: 4g calling, VoLTE icon not displayed?

Yes, I don't think it's working either.

 

I've never had an iPhone.

 

CSC is G965FOTF1BRF7.

 

Do I need a newer SIM card? I've had this SIM over 2 years (previously in an S7, never got VoLTE on that either despite it being apparently enabled). Although the SIM is 4G enabled is that enough to also enable 4G calling? 

 

I'll give customer service a call, but also appreciate any futher advice you might have - thanks.

When did you update to that version?
I'm not aware of anything specific required on the sim for VoLTE but it won't hurt to get a new one either.
