WiFi calling - Samsung Galaxy S9 Questions & Answers

Hey Guys,
Moved from the original pixel to the S9. On the pixel you could turn on WiFi calling through an option on the phone dialer. I can't see the same option on this dialer. Went into Vodafone and they told me that the phone defaults to WiFi calling when the signal is poor. Is this the case or am I being fobbed off? Making calls is really poor when in my house.
Cheers

It needs to be switched on in Connections/WiFi calling in Settings.

i believe it only works it the phone is bought from Vodafone - i know i asked them once and said only Vodafone phones can do wi-fi calling

Bobbed into three today to ask about it even unlocked handsets should have the Wi-Fi calling option she said wait for the samsung update which is out on Friday so hopefully all handsets follow suit

This seems to be carrier dependant. With a three SIM I do it see the option but I can if I switch to an EE one.

I have wifi calling available on my s9 plus which I bought direct from Samsung, go to the dialer, click the 3 dots in the top right corner. Then select settings, scroll to the bottom and you will see the wifi calling option which can be toggled on or off

It's not on mine I'm on three UK but on BTU handset
I'm hoping the update on Friday will give me the option

Ok so here's the kicker...the option appeared and I turned it on. Since then I have factory reset my phone (massive battery drain). Upon booting back up the option had disappeared again. Spoken to Vodafone and they have disabled and enabled it in my account but still no option to turn it on on my phone. Also got the march security update last night and still no option. This is driving me crazy

I've also got an S9 direct from Samsung (BTU), on Vodafone UK
- I'm assuming because they allowed WiFi calling on the S6, S7 and S9 with non-Vodafone firmware, that they'll allow it on the S9. It's the only thing I really need.
I hate carrier firmware, but would flash for WiFi calling as my signal at home is rubbish - I flashed my S8 on Three to get WiFi calling and VoLTE. But I'm a bit scared to flash the S9 on Vodafone in case I get the German CSC issue crop-up (does anyone know exactly what conditions cause this to happen?)
I'm not actually too fussed about VoLTE on Vodafone as their 3G signal is pretty strong everywhere (apart from at my house!), but with Three VoLTE was vital to get a reliable signal in a lot of places.
What is this update on Friday (today?) - is this confirmed or is this just something that the Vodafone staff (or Three?) are fobbing people off with? First I've heard of it.

And it's gone again...trying to explain to the "technical" guys at the call centre results in me losing my temper and them supposedly ringing me back in 1 hours time because it will be fixed... Seriously getting p****d off!!!

Any further news on this?

I've got the toggle set to on, but still no wifi calling (just says not connected to network when trying to phone). I have also noticed the toggle switch appear and disappear at will - normally restarting the phone gets it back

So I'm guessing the only "fix" is to flash the three firmware on it?

Hi, i checked the Three website and the s9 doesn't yet show as compatible for Three wifi calling, i'm assuming that when they do it'll get enabled via a carrier settings update or something for unlocked phones (my unlocked iPhone worked this way).
For a list of the compatible handsets got to the website, not sure what the rules are about posting links so search for 'three wifi calling' and it's the top result in google.

True it doesn't list them, but upon speaking with three they state the device is supported for WiFi calling, but only if purchased directly through three. Reason for this is the device them comes with there carriers software to enable the feature.

Ah thanks, in that case it's false hope for me and i'm now completely stuck! really don't want to flash firmware.....

I'm on O2 and what they have you do is download My O2. Select the option to enable 4G and WiFi calling and it checks compatibility and activates it within 24 hours. Then follow the guide in this thread to enable WiFi calling.
The only problem is I can't tell if it's working or not. It does appear that the line is open longer. My current router doesn't provide the depth required to monitor traffic on devices connected to it. Annoying.

There seems to be a software issue with the s9 and wifi calling. For me, its available (Icon shows in taskbar) , then next minute it's gone. After a reboot it comes back. I made a wifi call when I saw the icon again, and it switched to 4g mid call and the icon didn't come back again until after yet another reboot. It always bombs out pretty quickly after a reboot. I woke up this morning and saw the icon return on it's own this time (hadn't rebooted since last night) only for it to then disappear yet again. It's very buggy. Got an iphone here too which annoyingly works flawlessly with wifi calling so it's not an issue with my router.

Wifi calling
I just pull my notification panel down all the way and wifi calling is just there I'm assuming you have to be connected to use it. It would be good if it was able to use wifi signals while you were out without having to be connected. Touch wood my calls have been good so I only use it at home when phone reception is not as strong

On a U.K. DUOs model on O2 WiFi calling is fine.
Do remember the phone is a bit picky about the WiFi network and at some places just wont enable it.

Wifi Calling issue

This morning I decided to do the lollipop update, everything seemed to go well and im pretty sure my wifi calling was working after I did the update, now later on this afternoon I cant get it to connect its showing a wifi calling symbol on my notification bar with a slash through it and keeps telling me Wifi Calling connection error, anyone have any idea how to fix this? Thanks!!
Yep, I'm getting the same thing today. It happened the other day and I restarted my phone and it resolved itself. Today a restart hasn't fixed it. No idea why it's not working. Nothing has changed with my phone's software. Doesn't make any sense.

I didn't try WiFi calling since the update last week, and sure enough, I had the same issue. I even went as far as doing packet captures on my network to see what the issue was. I found a few "fixes" on the Sprint forums but none worked. So, I have two SSID's at my house, one is 2.4Ghz and one is 5Ghz (a new access point) I always connect to the 5ghz here at the house (but I don't use wifi calling at my house). So, for the heck of it, I switched my connection to the 2.4Ghz and turned on Wifi calling and BAM! It worked(I had previously used wifi calling on this network when I was testing it out when I first got my phone last year)! I switched back to the 5Ghz, didn't work. What I did to get it working: While I switched back to the 2.4ghz AP, i went into SETTINGS-WIFI CALLING, pressed and held on the 5Ghz network and tapped "remove", then re-added that SSID to wifi calling and now it works.
Please note I also have "Wi-fi Range Alert" and "Update address Notification" selected in Wi-Fi Calling settings (three dots on the upper right hand) and it did ask me to update my address information (and I saved the information). Not sure if this is critical, but I can only say this fixed the issue I had. Also note that I had previously tried:
1) Clearing the cache from APPLICATION MANAGER-ALL-> WFC SETTINGS and WI-FI CALLING
2) Dialing ##72786#
I can't say for sure doing the above two things actually did anything to help.
Earlier I tried reprovisioning my phone and it didn't fix it, also tried other things, so decided to give sprint a phone call a little bit ago and they had me go through the provision process again but they were refreshing it on they're end and it fixed the issue, hope the same works for you!!
Edit: Maybe that's what I didn't do was clear the cache before provision, I did it after wards!

It was fixed, now its doing it again, I bet its this sweet modem that im renting from Comcast, what a joke of a company
Having the same issue sperradically. Literally just before clicking on this thread I went to my phone and it had the symbol with the exclamation mark, pulled it down said "Connection Erro..." tapped on it, made a 'boop' sound then nothing) which is what I had since I got home around 5:30 today... and by the time Ifinished reading these posts, it went back to "WiFi Calling is Ready"
today I wonder if they were doing maintenence or something since a lot of ppl had the problem, (for me I first turned it on day-before-yesterday and it worked great till today though I might just have been lucky) I tried turning it off and on, I tried forcing stop and restarting, re-setting my location, etc and I still got the same error till just now, so... yeah... Sprint WiFi Calling seems flakey... (I have a skype in/out account I've been using for calls since I dont get decent reception and was hoping to replace it with this, but...)
Same here, decided to update this morning and WIFI calling is dead Jim. Tried reprovisioning after a cache clear, no change. Still dead, which sucks because I depend on it due to my in house signal being so poor.
Anyone have any other ideas?
If your desperate you can do what I did to solve my lack-of-reception...
Set up Skype
Add a skype-in number (~$4/month iirc)
Add skype out subscription (~$4/month iirc)
Activate "Google Voice Integration" on your sprint account
Add the skype-in number to google voice
turn off voice to the sprint mobile device (inside google voice)
Now when people call your number it gets routed through google-voice to skype, which will ring on your phone like normal. (just dont plan on getting a Gear because so far I've found NO way to accept/place skype calls using the gear)
Follow up that has fixed my issue with WFC after the 5.01 update on my Note 4.
Contacted Sprint via Chat.
updated Profile and PRL under system update in settings.
Pulled the battery for 30 sec and restarted. Turned on location and updated E911 settings and I'm back up and going.
Update:
For the last two days I've had no issues with wifi calling except when I went to town (where I dont need it anyway) it even reconnected and worked when I got back home. Dont know if it was a fluke or I've just been lucky, but it seems to have stabilized for me (at least for now) will report back it if acts up again.
UPDATE 2:
welp, looks like I jinxed myself. not been able to use wifi calling all day now...
Noticed a pattern though, last time it did this was when it rained, I wonder if wifi calling requires the GPS to be connected so rain kills it. (or it might be a coincidence, just something to think about)

Don't rent modems from the cable company. Usually its a cheap piece of crap. For what they charge you to rent the modem you can buy one on anazin/newegg and it'll pay for itself in less then a year

Will it support T-Mobile WiFi Calling?

Will it support T-Mobile Wi-Fi Calling? I know Android M supports WiFi calling natively but will the carriers (T-Mobile in particular) need to do anything to allow it?
WiFi calling is very useful to me at home where cell signal is very poor.

Out of the box, at this moment, I don't think it does. However T-Mobile got it working on the Nexus 6 so I don't see why they couldn't add it with an update either before or after they ship. Think positive :thumbup:
Edit: found this from another thread in general section
"It’s also worth mentioning that*T-Mobile has already said*that the Nexus 5X and Nexus 6P should have Wi-Fi Calling support at launch. While it’s expected to be turned off by default, T-Mo has said that after you pop in your SIM and hook onto the network, you should be able to turn the feature on."
Google or T-Mobile said via Twitter or the AMA or somewhere that it does support WiFi calling out of the box, but you need to set it to be on when you get your device - it isn't on by default.
The TBD support is for T-Mobile VoLTE/Band 12, which Google said they hope will be ready to go by ship day.

Excellent. Both will help.
Do texts go over wifi as well with wifi calling enabled? At work I only have access to wifi or Sprint (because I am in a basement of a building) and it has a Sprint DAS antenna system installed. I was thinking of switching to Project Fi due to it being on Sprint's network but if texts can go over wifi with T-mobile I would probably go with them since it would open me up to a huge choice of phones in the future (I kind of want to try a windows phone sometime)

Yes, texts will go over wifi. Hurry with that Windows phone, before the platform dies completely
Here's the Twitter post where I saw confirmation from T-Mobile on Wi-Fi calling: https://twitter.com/TMobile/status/648919023158206464
The initial question was on band 12 support (hoping we get this soon), but below there's a question on Wi-Fi calling to which they said yes. This was one of the main reasons I'm switching to one of the new Nexus phones - most phones support it on their stock ROMs, but once you get sick of stock and switch to a custom ROM you have to give up Wi-Fi calling.
Question for those of you on T-Mobile...
We all know WiFi calling is enabled, BUT, has anyone seen or regularly sees any kind of indicator that they're actually connected through WiFi calling when on a call?
I have seen twice on the signal tile, it say "T-Mobile WiFi calling". But that's it. I have the setting set to WiFi preferred and I even have the T-Mobile WiFi calling Asus router, but I don't know if it's actually using WiFi calling it not.
If I have zero signal indicated on the signal tile, but WiFi on, I'll get a message telling me to connect to a wireless network when I try to place calls.
I'm also assuming that means the signal indicator tile serves a dual purpose in regards to also showing WiFi signal strength. Because when I'm on WiFi, if I switch on " cellular preferred" (in WiFi calling settings), I'll see the LTE symbol next to the signal icon in the tile, but If I switch to "WiFi preferred", any cellular symbol (LTE, H, 3G) goes away.
On a side note, if you're in airplane mode, you can't make a phone call, even with WiFi on. On my S6 edge, I could, as long as I was connected to T-Mobile WiFi calling. But the phone would let you know with a status bar icon.
I really need WiFi calling in some places at work and I dumped the S6E partly because of the 5X utilizing WiFi calling, so that's why I've wasted all you folk's time in reading this long post. ☺
Well, son of a *****, look what finally popped up...
It was enabled by default as soon as I booted with the TMO sim and ran the update.
Great to read...looking forward to trying it out when it arrives.

As was mine, but it didn't seem to want to work. I had "cellular preferred" set, but it seemed to hold onto the cell signal too much and not want to switch over. I set it to "WiFi preferred" but it still wasn't connecting yesterday. Today however, it's been all good with WiFi preferred. So it might have just been my work's network yesterday.
I still got to see if the phone will hand off the call to cellular before I leave it on WiFi preferred. I'm guessing it only will if I'm on band 12, but I'll test it anyways.

Missed calls not showing, and late SMS

I'm having issues when on WiFi and LTE Enabled, the phone does not get any phonecalls, missed phonecalls do not show and SMS arrive late (my carrier has the option to notify me missed calls, but yesterday the message got me 10 minutes after the call).
After searching, I've found out something similar happened to nexus 4-5, when WiFi is ON, LTE is ON, and the phone is in Sleep Mode but nothing on Zenfone 2. Have a friend with ZF2 that confirmed it happens sometimes but we doubt if it' s a phone issue or carrier issue.
Getting the network mode to 2G/3G seems to fix it, but it misses the LTE
try to restart the phone (?)
I reboot my phone every couple of days, but the bug sometimes appears in the phonecall right after rebooting
What messaging app are you using? I know I miss messages from my wife when I had textra in the "off" state with autostart manager. When I told it to start when the phone boots it started getting the text messages and mms's right away. Are you using a VPN or do you have weak signal and what firmware are you using?
make sure phone is allowed 2g/3g/4g all. If you restrict it to 4g only you will face such issues.

I usually reboot in the mornings. But I US Google voice so the issues never really show up.
Stock FW (was on 168, now I'm yesterday patched versopm) , Stock SMS, no VPN, and set to 2G/3G/4G
As I said, the problem is fixed when I'm on 2G/3G, but it kinda loses the point to have an LTE plan
can you test with 4g on and wifi off.What carrier are you on. Because carriers can use wifi and lte combo in case you have same carrier providing both facilities.

I'm on Uruguay Antel and it does not offer any combo whatsoever, voice calls are usually switched over to 3G when I'm on LTE, but somehow the network or my phone fails to switch sometimes

No VOLTE/Advanced calling.

I picked up this phone a few days ago and I just noticed that VOLTE wasn't working like it should. The settings menu shows that I have the option on, but everytime I make a call or receive a call it instantly switches from 4g to 1x, and therefore I don't have simultaneous voice and data. Anyone have this issue too?
I checked my Verizon account to see if that feature is enabled for my line. Advanced calling shows that VOLTE is on for calls and video chat. Turning it on and off doesn't change anything, turning wifi calling on and off doesn't affect it. I've tried rebooting, and no luck. Seems like a software issue?
I noticed this on a call today as well. Subscribing...
Perhaps the person on the other end needs it as well? I've found calls between my girlfriend and I would switch from HD to non-HD and it seemed like it was due to service on her end. Just a thought. Its actually only happened a couple of times to me.

No luck with that one either. I've tried calling other lines on my plans and I got the same results. My S5 did a pretty good job maintaining HD Voice every time I made a call to those lines where LTE coverage was available.
I called CS and they didn't say it was a common problem, but they put in a report pretty immediately for me and should have someone contacting me the next 24-48 hours.
Just a quick update. I didn't do anything, I used my phone as is and it just started switching to HD voice and maintaining LTE while calling. So either they did something on their side, or the phone is just a little buggy.
I have never had that VoLTE icon pop up on my phone but if I look in my recent calls list I do see a Wifi icon on some of the calls.. I assume this is VoLTE??

That's WiFi calling.
I have used WiFi calling and it seems to work alright. Is this the same as VoLTE? If it is not how do you enable VoLTE?
I just found it in settings, it is enabled however I have never seen any kind of an icon that it is working. How do I know if it is or isnt?
Where is the setting for VoLTE in Settings? I am not seeing it anywhere.
EDIT: A google search showed me it should be in call settings, but it is not there. Any help much appreciated.

Verizon WiFi calling busted in Android Pie?

I recently updated my Verizon Galaxy S9 to the Android Pie release. I had previously been using WiFi calling on my home network, but once I updated to the Pie release it no longer works. In fact, despite lots of interaction with Verizon support, I have been unable to even access the settings to enable WiFi calling. They simply are not there. Are others seeing this? Does WiFi calling work with Android Pie on Verizon?
Thanks,
Craig

I am wondering the same thing. After updating to Pie last night, my S9+ no longer has the WiFI calling feature.
Wi-Fi calling would help out big time since our cell tower strength is very low at my house. I hope this isn't Verizon's way of them forcing people to purchase their mobile extenders.
The Verizon support rep certainly seemed to believe it should have been there. To the point that she declared my phone has a manufacturing defect and shipped out a "new" one. I guess I will see if that one behaves any differently. Like you, I'm on the edge of the coverage and WIFI calling has been helpful for battery life.

Well, how 'bout that. Too bad that the VZW representative didn't know that! It would have saved a bunch of time.
except it doesnt turn on for me on my note 9 it just trys and says unable to at this time . The only way I can get mine on is to turn on airplane mode then turn on wifi , then try to call someone and turn on wifi from there. But after I take it out of Airplane mode I have to do it all over. Spent 1 hour on the phone with Verizon . I own my Construction Company and this is the only phone I have for work . On top of that we are in a dead zone in the middle of Denver Colorado where my Home/Office is. 1k POS phone is only good for a paper weight . I have to call with my google home. This is miserable. Yes, I factory reset and trouble shot for more hours than I can spare.
I know this is the S9 forum. But I just got the update on my Note 8 and my work S8. Both of them are having the same issue. There's a notification about Wi-Fi calling Saying to tap here to confirm or update Emergency Location Information. I tap that it Says loading this may take a few moments, then says it's unable to enable Wi-Fi calling. I go through the phone App and settings and try to enable it there and get the same results. Before PIE i had this enabled already on both phones too.
Saw the same issue on a T-Mobile forum. No resolution there either. https://support.t-mobile.com/thread/149929
I updated to pie on my Verizon note 8 yesterday, ever since I've had the same problem as twiggle ^
I can't get rid of the notification to update emergency location information and I can't turn on wifi calling. Same message as him.
Same in Note 8. Prior update fixed it when prior update broke it.
The only non-extreme way to remove notification is to force stop the system app... after every reboot.
Waiting for a VZW hotfix. Like I did for 6 months prior.
Same thing happened to me after the Pie update. Clearing data and cache allowed me to turn it on with my s8+. When I try to update emergency address, that still fails though.
