Are you saying Tesco now have VoLTE on O2? If so has anyone tested to see if Giffgaff now works?O2 & Tesco NOW SUPPORT EVS!!
Untrue, i daily drive Three and regularly receive incoming HD calls from Vodafone, O2 and their MVNOs but not from EE. Only outgoing calls to EE are HD.
Tesco VoLTE to Three VoLTE

Back on iPhone EE now but last week I was on a Samsung S20 FE with Smarty, calls to EE showed HD, calls to Three showed HD+, calls from EE showed HD, calls from Three showed HD+can only receive HD calls from 3 numbers.

Yea, it was inbound from EE and showing HD, I didn't test further than that. VoLTE icon wasn't there on Samsung, but the toggle was on? Maybe it's hidden by some carrier policy (Also in South East)But were they actually HD and over 4G?
It's possible what I've been seeing is regional (I'm in the South East) but I've never seen a real HD call (i.e. not a narrowband codec) to 3 from another network over VoLTE, yet Three can make outbound calls fine to EE/Vodafone.
I have seen "HD" appear on Android phones for non-HD calls however (implying an HD coded being used withing the network), which is probably due to transcoding before legacy SS7 peering. However I don't think I've ever seen the other phone in that situation show HD.
EDIT: If you're on Smarty all outbound calls should be HD. It's inbound from EE/Vodafone that I've never seen.
They can be hidden by a carrier setting. Two SIMs on my phone, one EE and one Lebara. EE shows VoLTE icon, Lebara doesn't, but Lebara is using VoLTE (remains on 4G unless I turn the option off for 4G calling where it drops to 3G).Yea, it was inbound from EE and showing HD, I didn't test further than that.

Same with Smarty, VoLTE works just fine but they haven't bothered to create a carrier profile to display the VoLTE icon on Samsung phones.They can be hidden by a carrier setting.

Similar oddity with Wi-Fi calling. Both Lebara and EE show VoWiFi icon when connected, but Lebara also adds on Android a non dismissable notification that Wi-Fi calling is on, EE doesn't. There are a lot of carrier configuration options for what to show on the phone, at least on Android.
Smarty use the exact same IMS service as Three, so it counts for both. Vodafone have only recently enabled HD calling TO three, but it does indeed now work. The only call that isn't HD on Three/Smarty is an incoming EE one.If you're on Smarty all outbound calls should be HD. It's inbound from EE/Vodafone that I've never seen.
Only EE, Sky and the now legacy Virgin Network display the VoLTE icon. Funny that Sky and Virgin don't even support HD calling. Maybe it's to make themselves feel betterSame with Smarty, VoLTE works just fine but they haven't bothered to create a carrier profile to display the VoLTE icon on Samsung phones.
(Tut! I would like one)
It has certainly never shown on my S23 Ultra so far, maybe they'll get around to it one day, but then again, maybe not.
It was Smarty themselves who told me this.![]()
Sorry a bit confused, doesn't VoLTE = HD Calling, so calls over 4G have to be atleast "HD"?Only EE, Sky and the now legacy Virgin Network display the VoLTE icon. Funny that Sky and Virgin don't even support HD calling. Maybe it's to make themselves feel better![]()
Nope, VoLTE solely means the call is done on 4G to an "IMS Server". I used to think this too, but the actual feature that is HD and HD+ Calling has to be enabled within the IMS server of both phone's networks for it to actually work.Sorry a bit confused, doesn't VoLTE = HD Calling, so calls over 4G have to be atleast "HD"?

That's the beauty of VoLTE being packet data, even on very low signal (like -128dbm) I've still been able to make a crystal clear call.I’d probably always expect it to be rubbish calls.
I’m more surprised of who actually has time to use to check this stuff out.
I’d probably never notice unless I’m out in the sticks, but with 1 bar signal if anywhere, I’d probably always expect it to be rubbish calls.
That would involve agreeing on a codec though, and which one would you choose, g722, g729, opus?It would be nice for VoIP providers to work on interop and for higher quality codecs to be usable outside of the local network. For a brief while I had BT Digital Voice and HD calls between the landline and EE/BT mobiles was a nice surprise.
