[Q] Receiving no calls out texts while on WiFi

Hey guys I did a search and found nothing. Any time I'm connected to Wi-Fi, I can't receive calls or texts. I'm on Sprint. Anyone else have this issue?

Yes, have done tons of research and am having a similar issue. It's believed to be software related. If LTE or Global are set as the "Preferred Network Type" under Mobile Network AND wifi is turned on, then the mobile signal cuts out when it goes to sleep. With 3G set, the phone works fine with wifi turned on. I've tried wiping the phone and also loaded the factory 4.4.2 image via fastboot this morning and still have the problem. Some people have RMA-ed their phones and still report the issue, so it must be a certain combination of settings. It's also being reported from Sprint and T-Mobile user, so it's not restricted to just one network. As for me, I'm on Sprint in NYC, have an AC router and using an Airave. My Galaxy S4 didn't have any problems.
Here are a few threads that I've found:
XDA - Signal Problem
XDA - Signal issues with new baseband solved by flashing older baseband
On Google's forums:
Nexus 5 sometimes doesn't ring when people are calling

Thanks man, I had read the Google thread but hadn't find the XDA ones. I'll try forcing 3g while on Wi-Fi.

No problem! If you're on Sprint, there is also this:
Circuit Switched Fallback Issues on Sprint
I'm in an area that is reported as not having the issue, so it's not that for me. Plus, I'm on 3G with the Airave. I remember having the HTC Mogul on Sprint and for a while it would just die if the signal was roaming. An update fixed it, but it wasn't fun. At least in this case the phone still works, not as advertised, but it works. Here's to hoping that it's fixed soon!

I'm the Tmobile user in the Google discussion. It's an annoying problem and hope it's fixed with 4.4.3. However the issue just happened to me in the last week before I got the 4.4.2 update. So I'm not sure what could have happened from a month ago when I got the phone until a week ago. Haven't installed any new apps since then.

This does seem to be working now that I am forcing 3g

Weird, right?
4.4.1 and 4.4.2 both have the same baseband and kernel. That's about the timeframe when the updates both came out, so I assume that maybe 4.4.1 is when the majority of users started seeing issues pop up?
From what I've read, this phone handles cell signals much differently because of the newer LTE TDD. It could be any number of things really, but I don't have the expertise to examine the code to see what was changed between the 4.4 and 4.4.1/4.4.2 baseband. I do believe that all of the Wifi and cell signal issue posts that are popping up now are related though.
I'm also noticing my wifi speeds bouncing all over the place (from ~180Mbps -- ~500Mbps) and I'm only a few feet away from my router. I have a Netgear r6300v2 AC router.
12/14/13 Update: I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue, starting on 12/19/13.
The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and it's causing this conflict. That's why everything seems to work fine when 3G is set as a preferred network.

thanks man!

do we have any update on the situation?

Yeah I wish there was an update soon because this problem is starting to become very annoying. Twice this week I had to check my Google Voice because my Text didn't go through on my phone

Anyone have a fix for this yet?

Does anyone know if any custom roms fix this?

I've read Google is aware of the issue and speculation says they will fix it with the 4.4.3 release.

questions:
(the 1st is stupid, but i'll ask anyways) - when this issue occurs, is the phone set to **wifi only** with 3g / lte in airplane mode?
or does it occur when just setting up wifi in ADDITION to 3g / lte?
&, when you typed Receiving no calls out texts while on WiFi , is your application for texting, hangouts?
if it's hangouts, then google neutered it to only allow text thru the cellular network,
but if you're simply joining a wifi hotspot at work or home, with your cellular network enabled, it SHOULD go thru, ive never had an issue like that with wifi toggled.. even with 4.4.1

just a note -
if you look at slide 7 on the qualcomm snapdragon 800's chipset (you all already know this)
http://www.slideshare.net/jjwu6266/qualcomm-snapdragon-800-mobile-device
there's only ONE chip to handle wifi, 4g, 3g, bt, etc..
with lesser BoM (bill of materials) just maybe, top level s/w userspace toggles, handle more than what meets the eye, the point i was making in another thread..
which not only effects our nexus 5s, but even other phones in various ways depending on the implementation of sw/hd, of the same chipset family..
& sprint has mentioned for the forseeable future, of providing phones, with these types of chips from qualcomm..
~go figure~

the ONLY reason i pointed to the network settings *home vs automatic* in this situation, is because,
the qualcomm sd 800 is an asymmetric multiprocessor, (as will future chipsets be) & you're losing other core networking functions, while gaining another, when you SHOULD have available ALL facilities -

It actually occurs when the phone is connected to LTE and WiFi together. If my settings were to connect to 3G along with WiFi, SMS works fine.
I have to manually change my Mobile Network settings when I get to home or work, where I will be connecting to WiFi (note cellular service is always ,on, I didn't mean to make it sound as if I am trying to send SMS over WiFi). So when home I turn on WiFi along with 3G connectivity and when I leave I turn off Wifi and switch to LTE.
This issue has been happened while unrooted and running stock ROM and it still happens while rooted running Cataclysm.
Also note, the SMS we miss never will come through, it's not as if later on the message comes through...It's gone forever. It also prevents calls from coming through, it's not just limited to SMS.

Verizon Edge w/ Range Extender and Advanced Calling

Alright guys - Bought a new Edge on Verizon. I have a Range Extender at home. I am coming from a S2 that had no issues going from outside to inside. So Verizon apparently came out with a thing called Advanced Calling which pushed your call over the 4G LTE line instead of 3G. So it appears that the Range Extender is only 3G and if I have my Advanced Calling on it doesn't connect to the Range Extender.
Does anyone else have this issue? I'm not sure what to do about it. Any help would be appreciated.
PS The reason I can't turn off the Advanced Calling is because I will often be on the phone and on the web on the phone at the same time. This is normally where wifi is not available and Verizon is apparently deciding to force all Talk and Surf connections over the Advanced Calling.

The Verizon network extender doe s nt yet support LTE, they will release one LTE network extender sometime this year.
Advanced calling doesn't only require LTE, it requires XLTE or WiFi I think in order to work.
I use my Google voice # more than my Verizon and as you'd expect, can't use advanced calling when making calls using Google Voice bit I still clan talk and surf the web
---------- Post added at 08:43 AM ---------- Previous post was at 08:41 AM ----------
As a matter of fact, I posted these 2 comments while talking on the phone (Google voice). I don't use WiFi and I don't make my Google voice calls using hangouts, I use stock dialer and make the calls through Google voice.

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.

WiFi Calling on Mate 9 - Is it really there?

In the English USER manual for the Mate 9, there is a section under CALL SETTINGS that tells you how to Enable VoWi-Fi. They actually use this wording in the directions " Touch SETTINGS > Wi-Fi calling"
WiFi calling options are NOT present in the call settings menu for my Mate 9 (6GB/128 GB Model MHA-AL00 / Build Number: MHA-AL00 C00B137). I have the 2 SIM version sold by a HK seller on eBay.
My questions...
Is the manual is describing something different from the WiFi Calling from T Mobile that I'm very familiar with?
I use T Mobile as my USA carrier and have a T Mobile phone that does Wi Fi calling very nicely.
I put the same T Mobile SIM in my Mate 9...but the WiFi calling options STILL don't appear.
Is the Mate 9 really compatible with WiFi calling? What am I doing wrong?
Thank you.

The phone supports wifi calling but it's not a universal standard so each carrier does it differently (as far as I know). So it's probably not supported with US carriers, especially when it's not even released there.
I believe the phone might need a software update specifically to support it for T-Mobile. I think most carriers don't support VoLTE/Wi-Fi calling, so that might be why it has no option out of the box but a regional firmware update should enable it.

Being compatible doesn't mean it will just work. It means it will work if the network supports it.
T-Mobile will make sure that the phones it sells for its network will have the right software. An imported phone won't have that software and if you are unlucky it might not be directly upgradeable.
This is one reason why it's always a bit of a risk to import phones from another region.

WiFi Calling ...a few potentially useful tid bits...
Thank you to all! I'm pretty sure each carrier will keep the process as "proprietary" as humanly possible for obviou$ reason$.
Here is a tid bit I learned from Apple support on the topic of WiFi calling. As you may know, Apple 6S onwards support WiFi Calling. I was curious about how carriers 'support' WiFi calling on an unbranded / unlocked WiFi capable iPhone.
Here's the punch line from Apples...
If you use WiFi Calling on say T Mo..and then you want to pop in an AT&T SIM card....get this....you MUST do a factory re-set to enable WiFi calling with the newly placed SIM... Can you believe that? I change SIMS like underwear! Doing a factory reset for WiFi calling is impractical for me...

Does anyone know of any further progress on wifi calling from T-Mobile for this phone? Please share.

Well I have been able to make calls through the Google Hangouts dialer on WiFi, but doesn't seem to work to receive calls. Not sure how well it would work if I tried to port my number over to Google Voice, looked this morning said it would cost me $20 to do it.
But I'm likely returning my phone, not being able to get calls at home because the service in my building is poor... Pretty depressing because the phone is badass.

Google voice is not wifi calling as a feature set from either the phone manufacturer nor T-Mobile.
Wifi calling is when your mobile provider can service a connection over wifi, regardless of there being a cell signal or not. It treats your number as PSTN over wifi. Over it's (provider) servers.
Google voice is not wifi calling.
But I appreciate you taking the time to reply.

Google voice is wifi calling if you have a gv number lol

"Wi-Fi Calling is the conventional name for a technology that allows cellular packets from your phone to be transferred to your carrier over the internet, and injected back into the cellular network as if they'd been beamed over the air.
Unlike services like Google Hangouts and Skype, which let you talk to other people using call forwarding or an internet-based interface, Wi-Fi Calling lets you use your actual carrier phone number over the internet. Wi-Fi Calling is also distinct from VoIP technology, which lets you use an internet-connected phone exactly as you would a landline. VoIP transfers your voice over the internet to the switched telephone network, whereas Wi-Fi Calling connects your voice to your mobile carrier's network using the internet instead of cell towers."
So, it's not wifi calling as highlighted as a feature by mobile manufacturers and thus offered/utilized by mobile providers as a result.
This thread is specifically for the above mentioned capability. It would be best to not dilute the discussion with alternate options via additional apps. It would be misleading and misdirecting fellow readers.

The USA version does.
We have to wait for a USA firmware upgrade becomes available and update to that. If you have no interest in using funkyhuawe8, then probably sol unless they include in international ROM at some point.
Which k doubt because it would be included already.

It was around USA release. Not that important to me. Sure search will pull up something.
Edit.
It was volte I was thinking about. Until they release a update with wifi calling , Hangouts is the workaround

From everything I've seen the carriers have to approve devices for them to be able to utilize WiFi calling. It's one of the downfalls of having an unlocked device in the US as it's highly unlikely that a carrier will approve it.

That's correct, the while the firmware from Mate 9 supports it, there would likely be carrier/provider specifications that requires to be enabled. Huawei clearly does not have the green light from TMO for this else it would have been available.
This is the same reason, a TMO specific phone will have wifi calling, where as its international counterpart wound have it...

So using funkyhuawe8 will enable carrier (TMO) wifi calling?
Is this working for anyone on a L29 international version?

Thank you intruda119.
Any way you could shed some light on what exactly needs to be done using FunkyHuawe8 to enable wifi-calling please.

So does this have wifi calling on T-Mobile or not ?

No.

How to Use WiFi Calling

I've posted about this throughout the board, but I figured it would be better to make a thread since everyone keeps asking about it.
You'll need to install Google Voice and Hangouts Dialer and set them up. That's it. Just use the Hangouts dialer when making a call and it will do it over WiFi. If you wish to have people call you over WiFi, they'll have to call your Google Voice number.
This is a workaround, so you will be dealing with two numbers. Your carrier assigned number and your GV number. In my GV settings I have chosen to use GV for all calls, now I just have to get the number out to people. The other option is to port your current cell number over to GV, and then you won't have to notify anyone.
The VZW signal at my house is terrible, so this is what I do, and I can tell you it works perfectly. Hope this helps some of you with poor wireless reception.
Cheers.

This works so well, and I love the features that GV offers, call screening, texting from your computer, etc, plus the fact that I plan on buying unlocked phones going forward, that I decided to port my number over to Google Voice. Now it doesn't matter if the phone I buy supports my carriers WiFi calling or vice versa, and I'm only dealing with the one number I've had for years. Couldn't be happier.

Yeah, I just called ATT for help provisioning my daughter in law's replacement iPhone and while I had support on the phone I asked them about Wifi Calling and she said that our phone is not on the BYOD list for wifi calling. She said that very few phones are, it;s pretty much the iPhone 6 and 6s at this time.
Which is weird, because wifi-calling isn't even going through their network. That's the point of wifi calling, that you are using your phone on someone's wifi, so why does AT&T even give a rat's a$$ if you do that? So weird...

So if my network provider has WiFi calling as part of my deal as standard will it work without the work around?

If Wifi calling shows up in the settings menu, you should be all set, and won't need this. However, if you're on Verizon, like me, or AT&T like the poster above, chances are it's not showing up in your settings menu. So, if you want to make calls over Wifi, this is the way to go.

In the UK on EE ,importing it via the outrageous Amazon cyber Monday deal

That's a fine how-do-you. I guess that's another case for GV.

I'm on AT&T and wireless calling is in settings. Haven't tested to see if it works yet though

I'm on Verizon so I can't speak for AT&T, but in my case I don't have the option in settings.

Frankly, I don't care about Wifi calling except for that once or twice a year I am both out of cell coverage, but somehow manage to have wifi and need to make a call. With unlimited minutes and data, the need for wifi calling is pretty slim, but it would be nice for that once in a blue moon where you do.
I don't see why AT&T has to "support" the one feature that doesn't go through their network anyway...

After using Google Voice for free home service for about eight years now, I've also gone all in with it on my cell phone. I ported my cell number over to Google Voice, so I don't have to alert anyone of a number change, and I love all the features it offers. I can make/receive calls from my cell, computer, or home phone ( my Wifi ONLY tablet, too, if I want). All using my cell number. The lone home phone will receive calls to both our home phone number and my cell number. Texting can be done from my cell or computer. It offers call screening, call recording, conference calling, visual voicemail, and do not disturb. Finally, it makes all my calls as VOIP (internet) calls. So as long as I have a data signal, be it from my carrier or WiFi, it makes crystal clear calls. I absolutely love it. I wish I had made the switch years ago.

This is Voice over IP (VOIP), not WIFI-Calling. WIFI calling is when your phone can seamlessly transition between cell network and WIFI, so you can receive network calls over wifi.

Thank you, I'm well aware of that, but as I stated in my OP, this is a workaround for those of us who don't have the WiFi calling option.

Interestingly, after the most recent update, WiFi calling is an option in my settings menu. I'm on Verizon.

Does it work?

I don't know. I'll try when I get home tonight.

I can confirm that Wi-Fi calling works for T-Mobile on Oreo beta 1.

I can confirm that too... it works also for t-mobile on 7.1.1 :good:

Works on EE in the UK ,had to switch it on in call settings but working fine
