It doesn't seem to be supported yet on the iPhone 5S. Super Voice is available in Retford but I can't access it on my 5S, so being able to access it via Three in Touch would be great. I get a good 3G signal at home (no 4G though), but up the road at my Grandparents, the signal is non existent downstairs. My Uncle has given me access to his WiFi, but had it have been supported, I'm going home from uni this weekend message as the screenshot above, so my iPhone can't use it despite being a slightly newer device. Hopefully support will be added soon.

I'm on v4.9.5 here on my S4 Mini (10 Dec 2015 on the Play Store). As far as I know, that is the most recent.

4.9.5 is the latest for me too.

Swapping my SIM to an Honor 5X to see if the app works there. If not, I'll have to dig out an older phone/single SIM phone.

This is quite interesting although it didn't work on my old phone so either it's not supported (even though Three say it is) or the coverage map is a lie. When 3G signal was lost it roamed onto O2/Vodafone 3G900, not Three 4G800

Just to check, there's no special VoLTE setting in the Three inTouch app right? I just installed it, setup wifi calling and then turned off wifi and left it open in the background.

I'm gonna try in other locations and hope the coverage map was just a lie at my house, cause I really cba to put a Three sim in my iPhone just to check the 4G800 coverage lol.

It's really good that they're supporting more devices, something that their 4G800 VoLTE "Supervoice" really needs to be effective

It's good to see that 3 appear to be moving forward with their "fake VoLTE" for those of us who will never get the real thing on the phones we already own.


I don't think there's been any change in 3's coverage for a while. Especially not on the 1800. Still no coverage of St. Austell (largest settlement) or Truro (city) but apparently Redruth and a village in mid Cornwall is of utmost importance.

Maybe they've got to work out if the 4G will damage the plants?

My microwave has a setting called '800'. I'd always assumed it adjusted the power but now I know what it really means. Thanks!

The list of Three's devices has been updated too and now includes which devices are (will be?) VoLTE / 1800 / 800MBB / TINT800 enabled.

http://gdurl.com/bh81

Not sure why exactly 800MBB (mobile broadband) would be showing as Truefor devices without VoLTE or TINT800 (e.g. iPhone 5c)

The list suggests that the Nexus 5 is native VoLTE enabled (no mention of TINT). Also not sure what the Samsung Note 8 is!?)

That explains why it doesn't show up for me. Unless they're getting Google to roll out an update with it, I'm pretty sure it doesn't do VoLTE on any network operator anywhere in the world

Neither the iPhone 5c or the 5s are VoLTE capable are they?

With the supposed Android update that will enable VoLTE and Wi-Fi Calling on Nexus devices for any network, perhaps the Nexus 5 will be included then? Does seem unlikely though.

Ah that could well be it.
Some are a little peculiar though like the Lumia 735 is showing as VoLTE False, 1800 True, 800MBB True (no mention of TINT).

Also, tested Nexus 5 forced to 4G only and calls failed immediately so no VoLTE yet (Marshmallow 6.0.1, 1st Feb patch level)

Oh God, so that's why no one can get it to work indoors.
You have to put your microwave on 800.
Yep, microwaves, cellular, makes sense.
Can't understand why Three haven't mentioned this.
Crikey, good job I'm not on Three or I would be a bit annoyed.
My Microwave only has a 900 setting.

I guess it could happen. I believe the hardware is capable, and presumably Qualcomm have already sorted out their side (radio firmware etc), it would just take Google to integrate it all and do some testing.

I won't hold my breath though.


You must have the single band Vodafone/O2 version - in many houses it doesn't heat food properly

Although my microwave can operate on 800, the capacity of my traditional oven is greater and so it gets priority in most cases.

I can't believe EE haven't done St. Austell yet either. Mind you, they only just did Totnes so I guess it's coming soon.


Yeah, doesn't in mine. I'm changing it, been doing some research.
There now seems to be 2 main versions.
There's an EE Microwave that has 800 (not enabled yet though, firmware update required apparently) but it will work whenever, whatever. Food piping hot most of the time.
Then there's the slightly cheaper Three microwave. Apparently that works right away out of the box but you can't actually use it (and you end up with cold food) if there is another older microwave anywhere near you.
These had a 2100 setting I think and that seems to obliterate the 800 microwaves....

Can someone please explain what's what when it comes to using the Intouch app. I've looked on Three's site and it says my Z3 is compatible but I don't get how it works.

Thanks in advance.

They're not, but I though (or rather, was hoping) that the app was a bit of a work around. They can call or text over WiFi and use 4G, so I was wondering whether the app would allow the phone to connect to 4G800 and make calls and send texts over 4G as though it was a WiFi network (I hope that makes sense!). Strangely, it says 800MBB Enabled= True, but there's no mention of voLTE (obviously) or TINT800 either. So what's the difference?

Does anyone else in here have a (slightly ageing) LG G2? With the news of the In-touch app, I went on the signal checker, only to see it mention that the G2 is now Super-voice enabled (not the via-the in-touch app message that the S4 mini gives), subject to a software update.

If true, it seems strange that Three would update the LG G2, when the G3 doesn't report being Super-voice compatible yet.

My phone's not Three branded, so thought I'd check before attempting any firmware flashing etc.

Just had a look for the Galaxy S4 (my phone) and got this:

@{VolteEnabled=False; 1800Enabled=True; 800MBBEnabled=True; TINT800=True}

So no VoLTE as of yet, but it can connect to 1800 (which I knew). MBB is (I presume) Mobile Broadband, so if I had a purely data SIM, it would connect to 800. Don't know what TINT is though. Could anyone help on that one?

It sounds like that'll be the same as Pedro_C had with his Moto G 4G phone (same Connectivity info as your S4)
If you can find somewhere with no 1800/3G signal then firing up the Three In Touch (TINT) app should allow you to connect to the 800Mhz band for data (Pedro_C needed to put his phone in the microwave to test this!)

Hi, thanks for the quick response.

Aah,I get it now - so if I installed Three Intouch, I should be able to get connected to the 800 band? 3G2100 is very strong in my area, but 4G1800 hasn't launched yet - so if I lock to 4G only, I should be able to connect to 4G800 (if available).

With regards to phone calls, would they get routed via the inTouch app?

edit, this is what I got from Three's coverage checker:


Also, at my location, it seems that 4G800 is available. Time to top up my SIM and install inTouch!

Yeah that's how I understand it anyway.

As for calls, Pedro said he couldn't seemed to call (and/or was it difficult to test) via TinT, so your milage may vary, do let us know your results though!

Does this mean if you bought an S4 locked to 3, you could use 800 via TinT? Just looking for a cheap solution until the iPhone 7 comes out.

I think the idea with TinT is that it doesn't need to be a carrier locked handset. Pedro_C said his Moto G 4g was not Three branded/locked/firmwared.

This idea is just in discussion though, Three won't necessarily release this functionality it was just a concept that may or may not see the light of day - no confirmation of anything from Three.
