Just needs a new iOS version then.
That's what they did with WiFi calling.

For me it's the other way around

Rubbbish.. no change..

It keeps connecting to H+ and occasionallt 0 to 1 bar of 4G.

If you're roaming on Orange 2G, will the phone switch to VoLTE if available?

Supposedly Apple has mucked up VoLTE in the UK hence why the update has been delayed from Three. Vodafone are having similar issues.
How could they muck it up VoLTE is built into firmware a universal standard unlike WiFi Calling?

Interesting, if its 'mucked up' how come Verizon, T-Mobile and AT&T in the US are all using it? and AT&T has just launched WiFi calling.

I suppose it's unlikely you will be roaming on Orange 2G if 800MHz is available. However if you happen to roam onto Orange and then 800 appears, I would assume that it would be selected over Orange as the 800 will be broadcasting LTE in comparison to Orange GSM, so even if they are of equal 0 priority (I don't know how they sit in the priority chain so I'm guessing if 800 is at 0 priority then so is Orange) the phone would select the LTE signal over the GSM one.

Then again, that's just my guess. Would be quite difficult to test out as you'd need to get on Orange 2G where 800 doesn't reach and then travel to an 800 area without any 1800 or 2100. I know of areas where only Orange 2G and Three 800 reach but as of yet I don't have a supported device to test anything.

I thought if you were not on an LTE connection then the priority system meant nothing?

Well the 2100 3G is part of the priority selection, as in:
#2. 4G 1800
#1. 3G 2100
#0. 4G 800
#0. 2G 1800 Orange

So 4G 1800 is top priority, if it's available and the signal is within tolerance it will be selected. If the 4G 1800 signal gets too low it will drop to 3G 2100 and search to reacquire 4G 1800 whenever possible. The only time you see 4G 800 or Orange 2G is when neither 4G 1800 or 3G 2100 are at all available, your phone will not search to connect to them at all until it's lost signal completely of both 4G 1800 or 3G 2100.

When your phone is connected to 4G 800 or Orange 2G, it's been unable to find anything with a priority higher than 0 so it is able to select it. As soon as the priority #1 or #2 become available your phone will switch to that even if the signal is poor.

This is just my observation of how the network is based on my experience using it so feel free to correct me if I'm wrong.

Yes, but once you drop off an LTE signal (onto say 2100 3G, or Orange/roaming 2G) then the priority system is lost. Your phone has to lose complete service to then recover an LTE signal before the priority reselection is done.

Same if you're using data (e.g. satnav, or streaming radio) and fall out of 4G coverage to 3G, you'll not regain 4G until you stop the data usage and the radio goes to idle.

Actually the last time I looked it was...
priority ....
7 = 4G2600
6 = 4G1800
3 = 3G2100
I think 0 = 2G1800
This is for an idle device.
So there's room to squeeze 800 in either below or above 2100.
Anyway I think Pedro meant will a call handover from Orange 2G to EE 4G.... possibly.
I very much doubt it but you never know.
Obviously if the phone was idle it would always choose anything other than Orange if it could.

In my experience you'll get stuck on Orange 2G forever until you force your phone off it.

It's good to see Three adding to the list of handsets (perhaps they are getting a bit more confident) but until they sort this priority order I'm going to be seeing very little 4G. I can't believe they will keep this order as the 800 network is now so large that if they bounce people to 3G many people will never see 4G!

I don't follow. You say your phone has to lose complete service to recover an LTE signal, that's not true, it will jump up from 3G 2100 to 4G 1800 as long as the 3G data connection is idle. It's not even true for Orange 2G, my phone will switch up from Orange 2G straight to 4G 1800 provided it's idle and not on a phone call. That would indicate to me that the priority system is working outside of LTE. I feel like I'm misunderstanding you.

If you are using data over 3G, there's no way for the network to jump you up to 4G without losing your data session, as soon as it's over you will be reselected onto 4G. I don't see how that's priority reselection not working?

That sounds right for EE (seen as Three don't have 2600) but I was talking about Three's priority selection. As for call handover between Orange 2G and any part of Three's network, that's not happening.

In my experience you'll get stuck on Orange 2G forever until you force your phone off it.
I used to find this with my iPhone 4S, I'd have to airplane mode it. No problems with my iPhone 6S, it's not as quick as you'd like to switch back to Three but it's much quicker than it used to be.

Yeah sorry. Senior moment, got me threads mixed up!

Looks like I have to wait till mid December for the update even though the website says it otherwise.

Yet I'm getting only 7-8mbs on Three's 1800mhz standing next to the mast. Doesn't make sense.

Still kind of confused about how they messed up WiFi Calling as before Apple announced it there was no native WiFi Calling in the UK. AT&T, Sprint and T-Mobile US have launched VoWiFI on there networks now in the states. With AT&T and T-Mobile US having LTE-WiFi Calling Handoff.

I fairly often see 5-70mbps. It all depends on mast load, backhand etc

I'd be happy with that.. I just hope that when iPhones get the update that it's not a massive let down.. Says I have good coverage but from some other comments on here, it seems you can't really trust the coverage checker.

Skippy, do you get that level of signal indoors?

If you leave the phone to do its own thing are you basically never seeing 4G 800?

My phone will only connect to 800 indoors because the others are so weak, it connects at full strength for about 5 seconds then falls down to 1 bar -120dbm indoors on 800 despite the coverage checker stating i have excellent indoors. I am guessing that another mast is live but not open to use yet?

Any thoughts,

3 & EE planned to upgrade a mast close to me back in April but then they realised it wasnt right so they went back to planning and now plan to change the wide band antennas with dual wideband for 4 to 6 ports, it plans to have 3 800/1800/2100 and EE 1800/1800/2100.
The planning guys said it should now be live late December early January, I got this info from Wilkinson Helsby (Planning department)
