For sure Native is best, but surely this could mean that non-Three-firmwared devices will get access maybe sooner rather than later.

WOW! How did you just find that out.
They were telling me for a long time that the app will enable VoLTE for those device that are not from Three. I didn't know how they would implement it and I still don't know.

My phone has 800 but no official VoLTE (the hardware is certainly capable). It'll be intriguing if inTouch can work around that and make it work on a large number of otherwise incompatible phones.

Just doing a bit of browsing through the code in the background of the coverage checker to see if there was anything obviously new/interesting.

It seems Three's website guys might be bored though... their CSS classes are called things like barbie (pink), hulk (green), prince (purple), maggie (blue), hucknall (red).

The coverage map doesn't even seem to show what you could use, it just seems to show what would be possible if your nearest mast was enabled, which a lot of them aren't as I have been in a lot of the "perfect" areas with my G4 forced on 800 and got absolutely nothing.

A new version of ThreeInTouch came out today, which I have and band 20 is definitely searching and searching and not saying data service denied or whatever but it doesn't allow 800 access or VoLTE yet.

I wonder when they'll flick the switch, that would be amazing to just have the app running in the background to get 800 and VoLTE.

Sorry if it's old news but my iPhone 6 (a non 3 supplied one!) just updated its carrier profile to 23.1 - adding 4G voice to the settings menu!

I think it show 1800MHz as well as 800MHz on the same map so you can't tell where there is exclusively 800MHz. This includes even if it says your area is "superpumped" as it covers a wider area than just your postcode. I know because I have the same problem. I just leave it in auto mode now and accept that it will only switch when I need it.

Is this public release or beta?

I've just been looking through the code inside the latest InTouch android app (v4.9.5 just downloaded from the Play Store) and there is a lot of code in there for LTE/800 with reference to a company called Mavenir (who are now called Mitel. http://www.mitel.com/solutions/volte

Public, although I did have a contact for somebody in their dev team and I once tried a beta. The reason why is on the original launch I sent a bug report and they text me about it asking if they could call. They then followed up on a call and went through troubleshooting. They then fixed the issue, let me have the beta in touch and then let me confirm that the issues were fixed.

I'm not one to text people to be too hassily, I can wait the 6 weeks or whatever it might be until a public release comes out. I am happy to try and report any issues with the beta though if anyone has it or wants to message me a download link.

Yes it was people from Mavenir who I worked with on my bug report on the original beta I believe. They were very nice and they spent a lot of time testing and working on the bug with the TCP keepalives on Virgin Media, where the superhub would send a TCP RST after exactly 10 minutes and disconnect the presence TCP connection for the app, causing it to not get the packet which is sent to notify of a new call or SMS. The app would be green, but could would come in on the RAN instead of the app. That's why they put them menu option in for keepalives.

Technically it wasn't the app's fault, but as certain routers do it, I think they included that as an option just incase. Not sure if Virgin Media ever fixed the issue to stop their hub from sending the resets.

Doesn't the app automatically work out what the keepalive time should be (since it can vary from one connection to another) by monitoring when the TCP connection drops and then setting the keepalive to slightly less than this? Rather like activesync for Exchange servers now built natively into all Android, iOS, Windows and Blackberry OSs.
I'm assuming here that the app keeps a connection open without data necessarily traveling over it.
Or are you saying the superhub would send the RST command regardless of network activity.... in which case I needn't have bothered typing all this!!!!! Hahahahaha
Do I know what I'm talking about????

I don't suppose during that testing etc they mentioned how to enable an 'advanced' options menu or similar within the app did they? There seems to be hidden option menu items in there but I have no way of knowing how to enable the advanced menu to get to them.

It is very much meant to open a connection and then just sleep and wait for that special packet when a call or whatever happens. I guess they could have implemented something like what you suggested, but they didn't. Maybe they will now you've suggested it as I bet they read these forums when their company name comes up on google!

Most routers didn't seem to disconnect or RST those SIP connections on the SIP SSL port presumably because they know they are meant to sit open with little traffic except when there's activity? I know it wasn't a problem on most routers, no issue on BT, it isn't an issue on my Buffalo router, just a handful and sadly including some of the very crappy Netgear Virgin Superhubs. I was so annoyed with the superhubs shortfalls in several areas that I went out and spent a lot of money on a decent wireless AC 5Ghz router and put the hub into modem mode, best thing I ever did as all the wireless issues and this TCP RST issue just went and the router just works, exactly how it's meant to.


No, the beta versions I was given never had an advanced menu, just the same settings menu which is in the standard app.

Hhmmmm, native WiFi calling anyone???
Why not just stop buggering around with apps?
Just a thought.

Oh the trouble that Superhub caused Devon

As well as the TCP RST issue no matter what version of the broadcom wireless driver I tried on my laptop there was always occasional 5Ghz drops when transferring a lot of data across the LAN. It would run for ages transferring files at max throughput and go to limited or no connectivity with the yellow triangle in the notification. You'd have to disconnect and reconnect and then it would be fine, for another short while and then it would go again, this was even if the laptop was 2 inches from the Superhub. EVERY driver I tried, every setting on the hub's wireless settings, finally went out and bought a new router and magically once the Superhub wasn't doing the wireless it was fine, and now I can download at 120Mb/s on wireless!

Sorry for going off topic I just needed to vent about that mother of a wireless router.

You're right there's lots there, I'm going to have a snoop round as well.

Interesting here though.

This is Three you are talking about, it's run by a purple muppet .

Bit of advice anyone? Rang three the other day as my wife got a letter in the post about the one plan ending and she would have to change to another plan by next feb or they'd move her to another one automatically. So i phoned them to sort this out and at the same time i said to the guy, im lucky because i didnt receive any letter in the post, to which the guy said let me check something on my system. He then told me actually they had sent me a letter on such and such a date, but i didnt get it in the post. He said that my one plan was ending one month BEFORE my wifes plan, so jan then.
Should i take his word for it that they did send a letter and ive got to change, or should i ring back and tell them to keep me on the one plan until i actually have a letter on my doorstep?

Or is there no point because they could just type up a letter and send it out after i end the call?

I know they are going to put an end to it for good one day, but if i can get a few more months then why not?

Telling you on the phone is still giving you notice, they only have to give you 30 days notice of moving you to a new plan once your minimum term has been completed.

Presumably TinT won't be able to hand between wifi / 3G and 4G? If I'm on a call in my house (no service as yet) and go outside, I'll probably pick up 3G before I leave wifi range. Up the road I should get 4G800 although to be fair, will still be on 3G. Will it even work on 3G? I also assume if I start a voice call on 3G and then go out of the area but still have 4G or wifi, the call won't hand back the the app?

Seems a massive bodge to me. Although it may instantly allow more people onto Supervoice, an app is surely never going to be a proper solution?

There is native OS support in iPhones (both 6 and 6S I think ) and some 3-supplied Android models - presumably this will increase!

When I was with Huawei on Wednesday night, we talked about the 6P and how much support it has got from the operators - excluding Three.

I brought up VoLTE for this very reason (as I have a 6P and use it on Three) and that's when I got told that Huawei (and I assume that's Huawei and Google) are working on an update that will go out to ALL 6Ps and introduce VoLTE support for Three, but that it is down for roll out in Q1 or possibly even Q2.

I have to therefore assume that the industry is clearly well aware of the need for VoLTE support on as many devices as possible, irrespective of where the phone came from (given SIM only is now increasing in popularity all the time).

I hope that if Nexus devices get it, maybe other manufacturers will add native support for VoLTE on various carriers in future generic updates, so you won't need a Three-supplied phone, or to mess around loading on Three-specific firmware.

Meanwhile, inTouch allowing 4G voice means everyone using the app will get access to 800, which has to be a good thing despite the potential issues with handing off. At the end of the day, if I can make calls or use data in locations where I can't currently, that's worth the trade-off.

Agreed with Jon. I'd just like to get a reasonable signal indoors with Three.
