[Q] Wifi Calling?

I'm not even 100% if the N4 has it so can anyone verify this? I have horrible service on the first floor of my house (especially my couch smh...) so I need to know that this works

If it's the T-Mobile version, then yes you have Wi-Fi calling.

Yes it does
I got the white note 4 from tmobile on monday. Yes it does have wifi calling. It works well.

WiFi Calling Not Working
Just got my Tmo Samsung Galaxy Note 4 today after Pre-Ordering and Jumping from the Note 3. Decided to go with the SIM Card that came with the Note 4. Got the phone all set up and connected to WiFi and received "ER081 - Unable to connect" Error. Called Tmo and after checking my 911 info and verifying the new SIM Card was registered and such I got patched to Tech Support and reverifed everything. Popped out the battery while he reconnected the phone to the Tmo Network, same error. I have the Tmo Asus CellSpot along with another router as well, same error on both routers. The funny thing is they attempted to send some type of Verification Text Msg and I received "Content not supported" on my end. Anyone else having simular issues? I have good signal throughout my house, its just the matter of a major feature not working on a brand new phone. Tech Support said to give it till morning and call back if it still is not working.

texting doesn't work when I have wifi calling enabled

I suffered from the same problem and it seems to be a permanent problem as no amount of help from T-mobile could rectify the issue....so the phone goes back to be replaced hopefully by one with a little more luck!!! Ill be interested to hear how you get along with it!!

I found WiFi calling and text work. The voice had a lot of drop outs on the note 4 however. My wife's note 3 is perfect on WiFi calling without a hint of a drop out.

I'm starting to believe that TMO's version was not ready for release. I am now also getting the ER081 message, slow data speeds (as in <1 Mb/s with the LTE icon lit). These problems have really dampened my enthusiasm for the phone. :crying:

Does the phone intermittently show ER081 or is it permanent now?!

I managed to find that using another phone as a hotspot actually allowed me to get wifi calling...strangely though the cellular signal did not grey out.....when wifi-calling is enabled as preferred on others' note 4s, do your cellular signal stay on too?!

My Wifi calling took overnight to become active, probably because I'm a new customer and my account was still being provisioned. I have both the Wifi and cell signals in my notification bar.

People with the ER081....
You can try to following:
If your connected to your Wifi Network.
Go to Phone - Setting - Call - Wifi Calling - Switch it off and then back on.
This would re-enable the wifi calling feature and you will see the error go away.
Not sure why it gives the ERO81 code, but I have it come up as well.

First thing I tried. No joy. But, the problem seems to be intermittent and not permanent for me.

My problem is a little different. I get the wifi calling icon, but when I make a call, the other party can't hear me. When I turn it off, everything is A-OK. I'm not sure how to remedy this.

Call t mobile and tell them when new Sim card was activated WiFi calling was not set up perfect. Then before last step tell them to refresh you on network.
NOTE 4

I had an issue with my text messages using the SIM card that came with the phone. I returned to the store and they told me there have been issues with those Sim cards that are ISIS enabled due to the security measures. They gave me a non ISIS one and now mine works flawlessly.

I'm getting frequent Er081's on my TMobile Note Edge. I've tried 3 different ISPs with speeds from 10m-500m, tweaked the QOS and COS on each, multiple wifi's etc.
It will usually initiate the call. But it won't be long before call just drops, anywhere from 15-60 mins in. My calls are always long (>30mins), and I've yet to normally terminate a call. Of course I'm now getting asked what's going on.
On one occasion, the ER081 stayed on the drop-down and wouldn't go away until I rebooted phone (Edge).
IMHO this is a wonderful feature, but TMo is not ready for primetime on this one? Is it true Note 3's and older phones work fine?

OnePlus 3T On Verizon

So I was bored and wanted to play around and try to get this to work. So far I have been successful to get data text and mms working on 3G. Now I have noticed that when I boot the phone that it connects to LTE with a strong signal then it reconnects back to 3G its almost like its possible but something it blocking it. Has anyone had success getting further?

UPDATE: I have gotten FULL LTE on Verizon working. Currently trying to figure out a way to allow CDMA as well for calls

Ya good luck I had same issue as you . Talk text 3g working good. Or LTE only working .Never could figure out how to get them both going

Yea I know after hours of messing around lol and two sim cards wasn't satisfying enough I like the phone enough to jump off big red to try T-Mobile. I honestly like this phone better then my Pixel XL

I ditched my Verizon unlimited data plan for cricket unlimited and have no regrets. Best choice I ever made

Can you explain in detail exactly how you got this to work? I am dying to get this phone I had 1+1 when first realeased and left Verizon to get it, but now Im back on Verizon with my business phone and want this phone nothing else is close to this phone

It won't work it's one or the other. You are wasting your time

The city I live In has Verizon's xlte network and if you upgrade to advanced Calling then voice calls and messages all use 4g LTE data instead of CDMA, so I would only need LTE data to work, I was able to get the 1+1 to get Verizon's signal but after 5 mins they noticed and intentionally blocked me off their Network a message popped up on the 1+1 saying I had been blocked

You have to add VoLTE on the phone AND with the carrier. you did both of these options, and t hen were blocked? Did you ever call and ask "why?"?
Thanks

Just curious how you have "LTE" activated on the phone. I turned on "only LTE", but I get absolutely nothing. I am only interested in LTE on t he phone, I do not need to make voice calls of SMS

Force LTE provisioning
I know that people had the same issue on the ZTE axon 7 but we're able to force LTE provisioning by going into the dialer and dialing *#*#4636#*#*. This brings up a hidden test menu and under phone information there is a switch for LTE provisioning. It takes a few tries but eventually sticks on the axon. Can someone try this on the one plus phones to see if it works?

I know this has been rehashed many times, but I thought I'd share a my experiences of how to make the 3T usable on Verizon. Main reason I have the 3T is dual SIM and OEM bootloader unlock. Fantastic device. Switched from Verizon to AT&T just for the phone. The problem is my work uses Verizon. I refuse to carry two phones. So what I've done to solve this is bought the GravityBox app, which has a feature that allows, (among many things!) you to add a custom quick setting shortcut for Network Mode. It lets you decide which SIM the setting applies to, as well as any network modes to cycle through when pressing the shortcut. I of course pick the Verizon SIM. And only select two network modes: 1 CDMA only and 2 LTE only. CDMA only allows calls,text and 2G to work perfectly. When a sending or receiving a MMS on Verizon SIM, or needing to use Verizon LTE, I toggle to Verizon LTE only. This does kick AT&T offline for some reason, but beings that I rarely need to use Verizon data, it's not that big of deal.

VOLTE T-Mobile, not working (WORKING as of last update)

I'm experiencing issues with VOLTE on T-Mobile. My phone switches immediately from an LTE+ DATA connection to HSPA the moment a call is placed. Of course, VOLTE is enabled on the settings side. I'm running an unmodified system, upgraded to PIE.
I've been on the phone with T-Mo to make sure the APN is correct (nothing special to mention here). I've also tried different connection combinations using the *#*#4636#*#* with different results but, even though the phone connects really fast to DATA (LTE+), I cannot get VOLTE to function in any case. On the other hand, WiFi calling works just fine.
On a chat with Razer, they just told me that VOLTE is unstable with T-Mobile and, to disable the function altogether from settings.
Before I give up, I'm asking the geniuses here for ideas or experiences? Any ideas anyone?

I hope this can be figured out. Im waiting for my Razer 2 phone delivery and also on T-Mobile. What OS are you running? Android Pie?

Yes, I'm on Pie.

Good news! with today's update (3-20-2019), my phone is using VOLTE technologies to connect audio calls. Phone calls sound immensely better now (the "HD" icon shows up during the call and the "LTE+" connection indicator in the status bar remains through the call).

Unable to get wi-fi calling activated on Straight Talk network

Just got my Pixel 5 today and in reading up on it I discovered it has wi-fi calling capabilities. While this wasn't something I was actively looking for, it would be nice to have as the finished basement of our new house doesn't really get cellular signals, and even the rest of the house doesn't have the greatest cellular connection.
I do have wi-fi all throughout the house though, so if I could enable this feature it would be a bonus. I'm on Straight Talk, using the AT&T towers, and I'm just wondering if anyone has had any luck getting this feature activated with them. I've tried using their automated tool to see if the phone is capable, but it's telling me no. I don't see any options looking through the phone settings, and looking around on the ST site they don't mention the Pixel 5 in their FAQ section.
So is this phone feature only available on certain carriers? Do I need to get an updated SIM from Straight Talk (the one I'm using I've had for about 4-5 years or so)? Any help would be appreciated.

AT&T is very particular about what devices can use VoLTE and VoWIFI. i've found occasional workarounds, but for the most part you need an AT&T branded device for those features. AT&T has a running list of provisioned devices.
I'm afraid you are probably out of luck on this.

Too bad to hear this. Luckily, I've been surprised to find that I'm able to actually make and receive calls, at least in the main living area of the basement, so everything worked out okay in the end.

I can't promise you that it will work but from experience I'm pretty sure ..... If you can get customer support at ATT to provision your account for wifi calling AND put a dummy IMEI in your acct from a device that does wifi calling (one that is whitelisted by ATT) the wifi calling will work ..
I have done this many many times. The dummy IMEI had actually never been needed with pixel devices though, for me

Would that even work in my case though, since I'm not an AT&T customer? I have Straight Talk, which is using the AT&T bands/towers, but I'm not technically with AT&T.

Not sure if calling Straight talk sand using an IMEI from a phone that normally does wifi calling with ATT would work or not. Go to an att and copy the IMEI of a demo phone then call straight talk and switch to that phone

I may have to try that if it really starts becoming a problem. Surprisingly, as I mentioned above, I can actually make and receive calls in the main part of the basement. Maybe because it is the house above us, and not mostly the garage/solid cement like in the other portion where I was having trouble before, I'm not sure. It's pretty much just storage rooms in that section of the basement anyway, although that is where the internet comes in and the modem is located (the house is fully wired for internet, so I have a switch that feeds out from the basement to go throughout the house). Only time it would really become a concern is if I have to be on the phone with our internet provider while simultaneously working on the router or modem. Barring that, the phone seems to work fine throughout the majority of the basement, which wasn't what I was expecting.

Question Big issue, No Data during a call.

So One thing I discovered on this new phone of mine is that although working perfectly there is a major flaw in the way Internet data works during a phone call.
Any time you make a call, the phone downgrades the active signal from 5G/4G to H or E ( GSM).
Which in turns cuts off the data.
If I force 5G or 4G, then the phone call cannot be made. It just disconnects.
I have tried all settings, Volte enable/disable with no joy.
Some have said it's a carrier limitation, but it's not, cause in my iPhone, the very same simcard works just fine and the Internet is usable during a call.
Also tried with dual Simcard setup. As in the settings, the phone allows to use one simcard for data and one for call. Still not working.
Can someone please tell me if there is a solution please, or can you try your phone while on the call to see if Internet works as this feature is detrimental to me keeping the phone. If this doesn't work I will be selling the phone and getting a realme replacement.. Xiaomis sometimes suck with their non existent support.
Thanks

Global ROM 13.0.4
I can't see an operator fault if they have Volte services enabled and this simcard works flawlessly on other android systems.
As a matter of fact, any SimCard i have tried, so far 3 providers and the phone does the same thing. As soonest the call is made it downgrades the signal to H while full 5G or 4G is available??

the operator must provide the necessary information for each brand and phone to activate Volte and Wowifi.
On my 11t pro everything works with SFR and nothing with FREE because Free has not yet transmitted the information necessary to activate the services.

So went to see the operator. They sell Xiaomi phones. 3 network ( Three EU)
The phones in the stores are working just fine, no issues at all. And my phone simply just isnt.I have tried every possible setting and still not working.
See the screenshot below. As I'm typing this I'm on a super fast full signal 5G connection. As soon as I make a phone call, the phone will downgrade to E or H+ which is horrible. This network signal switching is also laggy, and If 2g signal is poor I cannot even make a call.

Does the "Use VoLTE" switch appear in the SIM card settings?
If not you can try the Dialer Code *#*#869434#*#*. That only will make this switch appear, but sometimes this is enough. It should also show the little VoLTE-Badge next to the signal strength (see screenshot).

I just had another look and on your 1st post it says the SIM is named "3 IRL", as far as I know Three Ireland does not offer VoLTE at all.
So it will always drop to 3G/H+ or 2G/E ... on every phone.

5G connection should support this naturally. If I put this simcard Into an iPhone or Galaxy the 5G connection stays on regardless.
Anyway even with Vodafone this doesn't work,so I'm thinking it either a phone limitation or a phone is fooked

No, for VoNR your phone still needs the same configs as with VoLTE. Though only a few operators support VoNR as of now.
