Call + Internet at same time - Ascend Mate 7 Q&A, Help & Troubleshooting

Hello,
does anyone know if there is a possibility to have phonecall and internet access at the same time?
As I have seen this is only possible on "H+" .
Is this a limitation of carrier or phone/android?
If it is phone or android related: Is there a setting that can be changed?
Carrier is T-Mobile D
I would like to have a phone call and access google maps while driving...
Also I would like to be able to send message or picture while calling (and not driving).
BR,
Robert

Your observation is correct, only 3G is currently able to provide both at the same time. 2G or native GSM doesn't provide enough bandwidth and unfortunately 4G came out without implementing the necessary protocol. This has been remedied however with "VoLTE", but only a couple of mobiles and providers have started to provide this service.
So if this feature is important to you set your mobile to 3G (WCDMA) only.

When u calling and u trying surfing too the data speed are drastically decreased because voice goes over 3g (depends where are you).and you trying to do multitasking over their signal which is in most cases impossible
But it has been slightly speeded up..
I red that mine operator (3) will be using 4g for voice calls at end of this year so it will be cool..
But one thing bugs me in that article (link below)that smartphone needs to support it too? Mate 7 has already this feature! Lte cat 6 ca or carrier agregation !

[REQ] Can I stop data when roaming?

Hi all,
I know this is probably a strange request and so I'll have to give a bit of background. Recently I changed my mobile provider to 3. 3 have their own telephone coverage in certain areas and if you are outside those areas you go on roaming with Telstra. The issue is 3 charges huge $$ when roaming on Telstras network for data (voice and SMS is fine).
My question is that my TP obviously knows when I'm roaming as it displays the service provider as 'Roaming'. Is there a program that will stop my data (and only data) use when I change over to the 'Roaming' service and activate again when I am in the 3 network?
Thanks for you help!

Hi, another aussie 3 user here...
I agree with the TS as this is one of the major problem we as 3mobile user face, is there any kind soul out there that could help us with this as my knowledge on PDA is limited.. Thanks for any1 who is willing to help in advance.
With the Sprint TP, I can go to
Settings>Phone>Services>Roaming
and set an option called "Data roam guard" that allows me to choose whether or not data connections will be allowed while roaming. I'm not sure if this option is available for you, but give it a try.
I myself would like to have an automated function for this. Until then I will have to manually switch to my dummy data connection.
Normally it doesn't connect on roaming.
and if it will, it asks first.
isn't this the case with you?
I have an app called NoData
Works really well and lets you enable/disable any data connections

I know about the NoData. However, you still have to enable/disable data connection manually. I'd like to have it automatically disabled when I am roaming.
For example my IM client (QIP) does not ask me whether it should connect or not. So it is very easy to have an "accident" with data connection :-(
I'm another Three user in Australia, looking for something like this as well. I often use my phone while on a tram and it might switch from 3G to Roaming while I'm browsing the web. I'd like for it to warn me so I don't download heaps while roaming (I think it's $1.65 per MB or something crazy like that).
Hi, another 3 Australia user here...and yes, I've been waiting on this sort of function for years now.
Part of the problem here is that 3's "roaming" is not actual roaming in the traditional sense. Normally, the phone detects a roaming signal when on a foreign network and displays a roaming indicator (looks like a little triangle) at the top of the screen. You'll find this is the case if you ever take your phone overseas and use International Roaming. Telstra's network does not give you this signal, and hence even the few roaming aware apps we have (e.g. pocket outlook) don't detect when you're on Telstra's network and turn off their automatic schedules.
The best way I could think of to do this automatically is with an app that detects either Telstra's network ID values (the phone detects these and translates them to the text "Roaming" at the top right of today, much as it translates the real value "3Telstra" to plain old "3" - 3 and Telstra share the 2100MHz network in a joint venture, much as Vodafone and Optus share theirs...you will see the real value if ever you use a non-3 rom) or the network connection type and then runs that NoData app (I haven't seen that before...credit to the guy who posted it).
I've often though some sort of even responder app would be useful. Something like Gyrator, except that read network status instead of physical hardware status. Anyone know of anything like this?
Then you could set up something like:
* On detect EDGE/GSM switch off data connections
* On detect HSDPA/3G switch on data connections
OR
* On detect network ID of Telstra's GSM network switch off data
* On detect network ID of 3's/Telstra's 2100MHz 3G network switch on data
Look at phoneAlarm.

My HTC TP says 'H' up the top when I'm in 3 coverage and 'E' when I'm roaming. Just near the top it says '3' when I'm in a Three area or 'Roaming' when I'm not...
Don't you have the same phone? What does yours say?

My point exactly. You will not see the real roaming indicator in Australia as you never actually roam here. While three call it "roaming" when your phone is on Telstra, the way they have set it up prevents the phone from knowing this is the case so the few roaming aware programs will not be able to adjust for it.
The phone shows G/E when on Telstra as Telstra provide a GSM/EDGE network. It shows 3G/H when on Three's network as Three are providing a 3G/HSDPA network. Hence, you can work out if you're roaming by looking at this even though it's not actually a roaming indicator.
If you look at your home screen though you will see either a "3" in the top right corner of the clock or "Roaming". That's what I was talking about before. It's not a roaming indicator either; it simply shows the network name (with a translation applied from the actual network ID in this case).
thanks caeci11ius, I'm glad you could explain this is better detail then my original statement. I am presuming that this form of roaming and charge to customers is quite rare.

You wanted a program which can automatically switch band when roaming.
This is the only program I know which can do that.

This is Exactly What I need Also. I have looked everywhere? I Dont believe anyone else has come across this issue before and has written something to fix it.
Need a program to detect when the Phone is in 3 or H area (displayed at top) and disable DATA ONLY when G or E is displayed. My work around at the moment is to select HSDPA only connection but this makes the Voice Calls dropout whenever I cannot recieve Three's Network. Can anyone help. There is many people who would be in this same boat.

3G - voice and data (do all calls take you to 1x)?

Hi All -
Sorry for a weird (simple) question:
I am used to GSM / At&T - where if you had a 3G connection you could talk on the phone and be on the internet at the same time.
Is CDMA / VZW different? I just talked to a tech and she said it wasn't possible.
Confused...
-Daniel
According to what I have read on this forum and experienced, with CDMA, you cannot be on the internet and on the phone at the same time.
If I am incorrect, I am sure someone will correct me!
KD8FRE
that is correct. It's not possible on CDMA.
Wow. Interesting.
I guess there's a map for that in AT&T's future.
Thanks all - appreciate it.
-D
I never really noticed any kind of problems with it. I can make a phone call while my phone is tethered and I can still also receive calls, I think it probably temporally boots you off 3G during the phone call but put you back on right after.
Yeah EVDO is "1x Evolution Data Only/Optimized" which means that once a voice call comes in you are switched to 1X mode.
The latest SVDO specification (recently released) allows carriers to quadruple their voice calls and also allows data and voice at the same time. However nobody has implemented this yet.
I believe no one will implement this.... Because all providers are going HSPA or right to LTE... Where we will be able to have data and voice at the same time.

Seriously though, what's the benefit of having an internet connection going at the same times as making a phone call? Please note, I'm not trying to be rude about this, I'm just curious about it.
Doesn't navigation(on sprint) use the internet? Im able to talk on the phone and still use navigation
There are some "live caller id" services which will do an online 411 lookup for any number that calls you, plus it's nice to be able to browse the internet to look something up while talking with someone (usually handsfree) for example if we're trying to decide on a movie or dinner or where to go out - all very handy to have a simultaneous internet and voice connection.

Two big ones:
1. Conference calls with email coming in. Like - your next meeting has been moved (exchange, push).
2. On phone call - someone asks a question that needs internet connection (I found it this way - they asked what the weather would be like on Sat (it was Monday). I said... hold on a sec... I'll find out... then realized that there is no internet... so I pulled my iPhone out of my pocket and checked it instead. Again - this is something that AT&T does today - just didn't think CDMA was behind the curve on it...
-Daniel
Cool, thanks for showing me the light
My problem (with Sprint) when I had to have a CDMA device is that there is a difference in signal between EVDO and 1X. For instance, I had full signal for EV, but hardly any for 1X... Thus I could be on data all I want, but I had troubles with phone calls....

These are the changes that Tmobile made to the phone

By going through the manual & comparing it to the EU version I've compiled a list of things tmous has changed on the phone. (in case anyone was interested)
Removed:
Quick Lookup - ability to select something & choose lookup through Google, Wikipedia, etc
Show Me app
Ebook reader completely missing even though HTC widget is still there
Voice Recorder
Voice Dialer
Dock settings
Locations
The Device Setup on first boot is missing things
Added:
Wifi calling (Tmobile's UMA feature)
I wonder why Tmobile removed all of these?
Here is a Voice Recorder app in the market that someone recommended since ours is missing:

What do you mean by "wifi calling"? is it calling via wifi using SIP provider?
If so, we do have it on our Vodafone UK branded units.
If it's something else, please explain.
well I guess it's good I havn't waited for the 4G to come and pre-ordered the British version.. just one thing, the WiFi Calling looks good.. (first time with Android and HTC xD) is there any way to get it in the UK Sensation Z710e ?

T-Mobile is a pretty cool system. When you're at home (or on a WiFi network that doesn't do much filtering), phone calls, SMS, and MMS inbound or outbound route through WiFi instead of the cellular network. I've noticed this has the benefit of improving battery life while on WiFi, as it turns off the WCDMA (3G/4G) radio. It actually seems like it might turn off the cellular radio completely, I'll have to check when I get home.
The one downside is that if you are on the phone and walk away from your WiFi network, it will drop the call. It can't hand off.
I'm not sure if this is common in Europe, but in the states, many wireless carriers offer femtocell units that users can install in their home if they have bad reception. WiFi calling eliminates the need for that.
Wifi calling will notify you of a mms but it will not download the message. At least that's my experience with the G2x.

ah sorry was just going off what I've been told regarding MMS. I actually don't use SMS or MMS, I use google voice for "SMS" purposes and don't have any use for MMS (if someone wants to send me a photo they just email it).
I have an unbranded phone from HK but also have Show Me and Locations. (Maybe the other stuff too - didn't check).

I think it shuts off the radio as well. My buddy had it turned on by accident & was freaking out because he was on wifi & showed no signal bars.

A similar feature to the TMOUS "wifi calling" is offered in the UK by BT Mobile. They call it BT Fusion.

Good call, I'm gonna need wifi calling at the very least before I'll hop over to an alternate ROM (who am I kidding I'm sure I won't be able to resist). The my account app is handy but it's in the market anyway (there was an update a day or two ago).

How do you activate wi-fi calling?

Does anyone know how to activate wi-fi calling on the Z5? I figured it'd be a menu setting, but I can't find it. I'm using the Taiwan version of the Compact and am using MetroPCS here in the States.
Thanks.
To answer my own question. It appears that wi-fi calling is only available with some carrier phones. So for instance, EE in England says on their setup page,
"WiFi Calling is only available on the EE version of the Sony Xperia Z5 Compact, bought directly from us in one of our stores, online at EE.co.uk, through our telesales team, or through corporate sales if you are a corporate customer."
So, I guess my question now is, is there a way to flash the phone so that I can get this feature on my non-EE phone? My carrier, MetroPCS, does allow wi-fi calling, but they don't sell the Z5 (and likely won't ever sell it).
You can try flashing the EE ROM with flashtool and see if you have that option. You will get carrier specific bloatware as well.
Would I be able to delete the bloatware? And I'm new to Android. When I flash, does it delete all of my settings and downloads and whatnot? I'm assuming I can back them up someplace in case it does, but like I say, I'm new to this. Also, where would I get the EE Rom from?
Look for Xperifirm. Download and install. You can get the firmware there. Next download flashtool version 0.9.19.10. You can bundle the firmware files into a ftf and flash, both with flashtool. Read the respective guides. To keep data, look at options when flashing and choose not to wipe user data. I would type it up but the instructions are on XDA, just search.
Neither WiFi calling or VoLTE will not work on the Sony Z5 unless your carrier/network offers the Sony Z5 for sale directly.
Note, WiFi Calling and VoLTE are two separate features but similar network functions on the operators side.
Note, MetroPCS is a sub-brand of the T-Mobile USA network so Metro is pretty much TMo USA.
Since T-Mobile USA does not offer the Z5 you will not be able to get WiFi calling working. In order for WiFi Calling or VoLTE to be supported the network operator must customize the ROM to include the WiFi calling and/or VoLTE network configurations. Unlike the typical SIM card and APN settings which are industry standard and can be adjusted manually. WiFi calling and VoLTE are somewhat more complex and include carrier/network specific security certificates to work. Apple can get away with supporting WiFi calling and VoLTE simply by swapping SIMs because the T-Mobile configs are loaded into their core iOS software which goes out to everyone around the world. (Probaly one of the reasons the iOS eats up so much storage...but i digress) Android runs much leaner and does not carry all the extra configs for all global networks...hence a carrier (i.e. T-Mo US) tweaked version of the Z5 ROM would be required for this all to work.
If T-Mobile USA offers the Z5 in the future you may be able to unlock the boot-loader and flash the T-Mobile specific ROM onto your phone and get WiFi Calling and VoLTE to work. But if T-Mo USA never offers the Z5 then you will never have WiFi calling supported.
Hope that helps....
WiFi calling and VoLTE are pretty much the same thing...just VoIP. And in most operators case WiFi Calling and VoLTE are the same back end network call processing systems. VoLTE is easier for the operator to secure as the customer is using the operators LTE and IP network. WiFi calling is seen on fewer operators as it requires more security since you can access the operators network from any public or private IP network.
---------- Post added at 10:28 PM ---------- Previous post was at 10:20 PM ----------
and in theory you could extract the WiFi calling stack form the EE network's Z5 ROM and load it into a custom ROM. That would give you the software capability to support WiFi calling....But you will still need the T-Mobile USA WiFi calling fqdn for the WiFi border controller and their security certificates which are typically specific to a handset model. And again since TMo does not offer the Z5 there are no Z5 certificates.
Ah, well that sucks.
Yeah I feel ya, I love WiFi calling too
Some network providers have their own apps to allow it. Like in the UK, O2 network has an app called TU go
All hope isn't lost - Android M is supposed to have a provision for wifi calling. I've read posts of people with Nexus 6's on M (google play editions, so no carrier specific models) that have been able to use wifi calling. The current loss of band 12 (hoping this will change too) as well as the loss of wifi calling as a fallback has been the only drawback to this otherwise excellent handset. I absolutely love the thing. It just works, no fuss.
I know this isn't helpful, especially for those outside of the US, but this is why I ported my number to google voice a long time ago. VOIP works great over Wifi for me most of the time and when I have LTE reception, I can still use Voip albeit with increased data consumption.

Do you know of any guides for how this is supposed to work? I have Google Voice, and I have Hangouts, but I'm not sure how they're supposed to work in tandem for wi-fi calling. Would I be forced to actually open up the Google Voice app in order to make wi-fi calls? How is that any different from something like Talkatone?

Yeah, that's a bit of a pain in the ar$3. I install google voice and hangouts on any phone/tablet I get, Google voice is necessary to route all outgoing calls through GV so that my GV number shows up on my call partner's caller ID. (even though you can dial directly from the native phone dialer) I install Hangouts to manage sms and google talk (now just google hangouts but specified to avoid... or contribute to, (as the case may be) confusion) messages. You can also dial directly from Google Hangouts (this is the only option when you're only using Wifi, without cellular signal) So my thought flow kinda goes like this.
To make a call:
1)check for cell signal, if there is signal, use the native dialer to place a call
2) if there is only WiFi, use hangouts (or hangouts dialer) to place a call
Receiving calls: (If you need help I can tell you the specific settings)
1)when the phone rings, determine if it's ringing via Hangouts or the native phone app
2) check for cellular signal and wifi signal
3) if cell signal is 2g only, only answer with the native phone app (sometimes hangouts will ring first) and I have to wait for the native phone app to realize there is a call coming in (forwarded of course to my cellular provider number from GV)
4)if connected to WiFi, or I have LTE coverage (sometimes even on 3g) pick up the hangouts ring.
Sometimes I do miss calls because I'm waiting for the native phone app to ring when I'm on 2g, but hangouts rings first and the native phone app doesn't ring, but those instances are fairly infrequent and I can just call them back.

Also, sorry I've never used Talkatone, so I don't know if it works any differently. You don't have to have google voice installed to make / receive wifi calls via hangouts. you just have to have opted in to hangouts on your google voice account. The ONLY reason I still install GV is to make sure that when I make outgoing calls from the native phone app, my GV number shows up on the recipient's caller ID. They should really just bake this into hangouts and completely depreciate the GV app.
You could port the t-mobile wifi calling apps from the z3. I ported wifi calling to my att g2 from the t-mobile rom. It's not really that hard if you know how to read logcats
Many retail mobiles have "Wifi Calling" function but not any menu entry to enable , The APP can check the hidden function and enable it if can use.

Note Edge 915T Wont let me call while on LTE - Help needed :(

Hello all..
I have this issue with my Note Edge 915T (T-Mobile Variant). It is unlocked and I use it in Venezuela with Digitel (LTE BAND 3: 1800) and the phone DOES connect to LTE with no issues (I get the 4G/LTE icon), and I can browse with no problems, but no one can call me, nor can I make any calls or text. In other phones, when I call, data drops and I can call and when I finish, data comes back up. HEre, LTE stays up and my call does not get through. Then after some tries, it drops to EDGE and won't pick up LTE until I reboot or something.
If I try a different operator, it goes to HDSPA (3.5G) and I get voice and data (data drops while calling, but it ir normal), but I want to use my operator with LTE.
Im running MM and I deactivated VoLTE as my carrier does not support it, but is there something else I'm missing?
This may sound stupid, but have you set your APNs? You can also try resetting your network. Dial ##72786#. Also Does your carrier require any certain apps. Example FreedomPop requires a specific app for getting/making calls, as they are mainly VOIP MVNO...

Hi! thank you but yes, the APNs are perfect, I can use Data, the issue is that I cant call as the data signal stays in 4G/LTE and with my carrier, when calling, it drops data signal and it calls, here I can't. Im starting to think it has to do with CSC being with TMO, and I should use another one either from my country or a general One (BTU) for example. Will try to flash a rom from a different carrier to see if it works.
The only other option might be *#BAND# (2263),which could be dangerous, if you do not note original settings. Sometimes a complete ODIN can restore.
I normally use Nova Launcher - Widget- Activities- Somewhere under phone or settings. Shortcut Called PhoneInfo or DeviceInfo, which is much safer&consistently works! The app w/ same name no longer works. It took me forever & I always export my desktop, so I have that shortcut. The last option is an app called Samsung Phone Info+, but is paid or free if u know.... I really hate paid apps. It has under menu secret codes as well.
