Conference calling - does it work on your network?

Hi all,
I haven't seen anyone mention one of the more hyped selling points of the TP2 - the Conference Call feature. Does it work? And more importantly, does it work on your network?
The reason I ask is I am on T-Mobile UK with my Kaiser (and my TP2 when it arrives tomorrow) and I cannot conference two calls together - when I press the conference button, it says "The operation failed". A little research on Google seems to suggest that T-Mo UK are probably the only operator globally who have this functionality disabled.
Will this mean that if the TP2 is ever released through T-Mo retail that it will have this function disabled? Is that why it has been delayed - they are upgrading their network to cope with conference calling?
I'd be interested to know, especially if anyone has already got one on T-Mo UK.
Cheers

Im not sure about T-Mo
However, the option you need is Call Waiting & Call Conferancing; this option usually need to be activated with your telco under VAS (Value Added Service); some may charge to have this function activated
the best you call T Mobile and ask specifically about this function

As I feared, T-Mobile UK don't support conference calling so that feature doesn't work. I phoned CS yesterday to ask, and all I got was "it may be supported in the future".

Actually I found my TyTn II did this yesterday. I put a call on hold and saw an exciting 'conference button' in the Opal dialer. Pushed it and I got some message about not being supported.
I'm on Orange.

UK o2 = No no no.
Pretty pointless feature when the network doesn't support it, I don' think many uk networks do, they have their own conference facitlity. (232 on o2 I think)

T-mobile (ben) Netherlands: Yes, totally works. did it with my old hermes 2 months ago

Vodafone in the Netherlands supports the conference call facility.
A question I have in relation to this subject: does anyone know whether it is possible to have incoming phone calls join in a conference call? Example: I have a call with A on the TP2 and B calls me on the TP2 during that call with A. Can I organize that B will join the same call? If so, how? Is there any maximum of calls that one can have in such a conference call?
Cheers, dela

Telus in Canada does NOT support the feature. BOOOO!

It works on Vodafone Portugal

Vodafone in NZ supports this but only for account customers and by default it's turned off but can be turned on request for free of cost.

Yes, you can pick up the incoming phone call and join in a conference call you started (works well with Orange & unbranded TP2).

Your device already has Conference Call capability.
Using Conference Call is a network dependent feature. So, based on what your operator allows you (your phone subscription/plan) - you will be able to use it or not.
BTW, Conf call works great on Orange ...
Hope it helps.

Movistar in Mexico supports it, even on Prepaid, and for free (you just have to pay for both calls)

All Israeli operators (Orange, Cellcom & Pelefone) supports this feature

Mine worked twice on att then stopped, Any ideas why? I used it right when I got the phone then about 2 1/2 weeks ago and it worked great, now when I try I get two people on hold and the other call doesnt come through, and when I try to take the two peopl off hold is says it cant take the call off hold. Do you guys think this is a carrier issue like att not wanting me to use it or a phone/hardware issue?

Works with Vodafone UK

The Conference feature (aka Multiparty) requires a flag in your number's profile in HLR called "MPTY" activated. without that activated, you cannot make a conference call. contact your operator for this.

Actually my operator also have this service, but it wasn't activated in my number. Now it is... but it seems that the other numbers that you are making the conference also need to have this service activated, otherwise it won't work.

[SOLVED] 3-way Call Conferencing on the M8 831C not working

Hey guys,
Noticed a very weird bug on my 831C.
This is on a CDMA network, that I am using with an RUIM (CDMA SIM) after unlocking an out of contract device and switching to RUIM mode using DFS.
On other handsets, I can make a call, then add a call and then merge the two calls. Worked perfect on my HTC One E8.
When I try to do this on the 831C, the first party continues to stay on hold and the calls do not merge into a conference although that is what it shows in the stock dialer app.
Is this also happening with anyone else? Are there any workarounds for this? I have tried CM12, ViperOneM8 and stock Sprint HK ROM.
Any help would be greatly appreciated.
Thanks!
UPDATE: This isn't a bug. Every network has its own command to establish a conference. I solved the problem myself. After making the two calls, you need to press the 3 little dots on the dialer and tap "PEOPLE". After this you need to swipe to the dialer pad, press 3 and tap the call button. This will join the two calls and a 3 way conference will be established. This method works on almost all other CDMA carriers. I have successfully tested this on Reliance CDMA India.

Solved this!

Getting voice over wi-fi on this phone? Anyone

Hello there, im trying to activate vowifi, i can activate volte fine but not vowifi, anyone got it activated and if you did how did you do it.
Sent from my SHARK MBU-H0 using Tapatalk

Are you in the USA? If so, that is the reason. Xiaomi phones are not whitelisted for wifi calling by ANY carrier here and this is not expected to change soon.
I am presuming you used short codes to turn on Volte successfully. The Wowfi code works also (phone is wifi calling capable) but its carrier disabled.
I bought a paid plan from FreeUP, an ATT MVNO, where you can use an app dialer to make outgoing wifi calls (and free unlimited international calls) but still no incoming wifi calls.
Same pricing as Mint Mobile.
(Fyi, even if you weren't using a global phone the only Android phones guaranteed to get wifi calling here are the ones the carriers here sell ... There are a few exceptions ... The newer pixels and a few others.)

No phones calls in France

Hello, I bought an S7A on eBay. I unlocked it with the GSM unlock code provided. Everything works fine, except ... I can't make or receive calls. When I make a call, no ringing tone, and it hangs up 20 seconds later. When someone calls me, the same, then they come across my answering machine.
I'm on the latest version of Oero available, no root or whatever. From what I saw (on GSMArena), the phone uses compatible frequencies in France.
I am at carrier Bouygues Teelcom.
You have any ideas ? Thank you !
PS: I translate from French, please be indulgent!

Same problem, this phone does not work in China

Since then I have understood the real problem: the phone cannot switch from the 4G network to the 2G network for calls on its own.
I don't know how I did it, but now I can make calls without any problem, but switching to 2G is very long (15 s).
I specify that it is impossible to use VoLTE to circumvent this problem.
For receiving calls, the phone does not switch to 2G and the incoming call still fails.
But I can force the 2G network (With the Samsung Band Selection app). And there, incoming calls work, but we only have 2G to surf.
When connected to WIFI, the phone automatically forces the mobile network to 2G, so incoming calls work without the application mentioned before.

Question Problem to use Motorola Edge X30 in USA

Hello, first of all I want to say that my native language is Spanish and I am using the Google translator to write this, so there may be writing errors and apologize.
Buy a motorola edge x30 and the imported import from China. The phone is unlocked to be used with GSM networks from anywhere in the world. When I bought it, I was with Metro PCS but in Metro I was told that the phone was not compatible with the 3G networks of them. After that I started to investigate and find a web page called kimovil and there I saw that the edge x30 was compatible in the USA with all the networks of 3 suppliers: Cricket, AT & T and T-Mobile: I choose to use change to metro by T-Mobile.
Immediately I left the T-Mobile store after making the change I have tried and could receive and send SMS, receive and make calls, and get access to the Internet without any problem. After a couple of hours of having activated services with T-Mobile, the phone could not or receive more calls (the Internet and SMS continue to work normally, the problem is only with calls). When I try to call someone, the call is not done and says "Hanging Up". I tried everything: Factory Reset, Networks Reset, modify network configuration, everything ... and I can not solve the problem. I went to T-Mobile to tell you about my problem and they tell me that the problem is not them but my phone.
If anyone knows how to solve this problem, I would greatly appreciate the help because I feel frustrated. Thanks

I have MOTO EDGE x30 with T-Mobile. Work perfectly. Check the SIM setting.

Good afternoon. I already managed to use the Edge X30 with the T-Mobile network. You just had to put the network selector on automatic so that you can use 5G, LTE, 3G and 2G as you see fit. The problem is that I realized that the phone only calls and receives calls in 3G and 2G, which limits not only the quality of the calls but also limits your coverage to be able to make calls since you can only make them in 3G and 2G . You who also use T-Mobile, does the same thing happen to you?

I'm not sure, but it supports 5G in N1/N3/N5/N7/N8/N20/N28/N38/N41/N78 and 4G in B1/B2/B3/B4/B5/B7/B8/B12/B17/B34/B38/B39/B40/B41. or check volte settings.

you may try to install "carrier services" app by google from the play store. it solves some of my problem with data connection.

Yes I have the same issue. Whenever I make or receive voice calls, the phone falls back from LTE to 2G. I looked everywhere on the phone for 'VOLTE' settings but could not find it. Does VOLTE work for this phone on Tmobile? Very frustrating.

Has anyone been able to find the solution for the calls switching back to 2g? I love the phone but this is extremely annoying. I'm on T-mobile. Thank you
