[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?

[Q] Help! D5803 on AT&T - not receiving text messages or calls

My new xperia z3 compact (D5803) receives text messages and calls very intermittently. I'm on AT&T US, stock firmware.
- If I am using the phone (or have very recently used the phone, say within 30 seconds) then most calls and text messages come through fine (though not always).
- If I leave the phone alone for more than a few minutes, text messages or calls almost never come through - though occasionally I get a text message many hours after it was sent.
- If someone leaves a voicemail (because I didn't answer the phone, because the phone didn't ring!), I don't get a notification until I open the voicemail app and manually sync.
- I can make a phone call or send a text message with no problems (texts arrive immediately).
I don't have any of these problems when I put my SIM back into my HTC One M8.
I've tried the following to fix this:
- I went to the AT&T store and had them give me a new nano SIM. It made no difference; same issues.
- I factory reset my phone. It made no difference; same issues.
- I updated to the US version of the firmware. It made no difference; same issues.
- I put the SIM into a second, until that point unused, xperia z3. It made no difference; same issues.
Given that I have exactly the same issues after changing both the SIM and the phone, I can only think it must be some kind of compatibility issue with using AT&T on this phone - except I see that many other users of this forum are on AT&T and aren't having the same problems.
I do notice that I don't have the best signal in my house (usually 1-2 bars) so I'm wondering if maybe that could be related? As I say though, my HTC One works fine, as do all of the other AT&T phones in my house.
I think my next step will be to go and buy a T-Mobile prepaid SIM, just to see if that works, but does anyone have any thoughts or suggestions? All in all this is getting pretty frustrating, because I LOVE the phone, but right now it's unusable for me.

I would suggest reading this thread below. It should give you some tips on how to resolve your issue.
http://forum.xda-developers.com/z3-compact/help/att-apn-settings-lte-t2888644

Thank you for trying to help!
I probably should have added that link as one of the things I had already tried. To be specific, my APN settings are:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http: //mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
---------------------------------
I'm beginning to think it *must* be a signal issue, even though all the other phones in my house are fine. I have the "Advanced Signal Status" app installed, but I'm not sure what I should be looking for to see if there's anything fishy

Don't forget to download the Internet and MMS settings for your phone. You go into Settings > Wireless & Networks > More > Internet settings and download settings for Internet and MMS

Thanks again for the suggestions.
Sadly, it's still not working. I'm pretty sure I had already downloaded those settings, but I did it again anyway (seems you can just download over and over). I even reset the phone after that just to be sure, but the problem persists.

I have the same issue and I live in Sweden....

Im having the same issues. I restart the device and then come all the missed calls and missed txt messages.. i really hope theres a easy fix to this soon.

So, I switched my SIM from AT&T to T-Mobile and it fixed my issues. It seems that the either the poor AT&T reception in my house or some other strange incompatibility between the phone and AT&T was the problem.
Either way there's obviously some kind of issue with this phone - my guess is that when connectivity with the network is poor, the phone maybe times-out and gives up. Perhaps Sony will fix this with a firmware update at some point. In the mean time I would suggest that other folks having this issue maybe go to a part of town where they know reception is very good and see if the problems happen there.

So after 2 days of of testing, a new nano sim card and several phone calls to ATT I found temporary fix. Change your Network mode to WCDMA (preffered)/GSM. While this wont give you LTE it will prevent the missed phone calls and txt messages and at least you have HSPA+ . The problem is the LTE connection to ATT. The connection either drops and or prevents phone calls /texts from coming through the lower HSPA + or 2g bands... Not sure why this is. Hoping that when the Sony Store models start shipping on Nov 2nd they have the same issue and Sony will send out an update to fix the connection issue.

I'm on the US ATT network with the same problem as well. After trouble shooting I have come to agree with you. I'm really hoping Sony sends out an update.

Is this a problem on Tmobile USA with Z3 Compact also?

same issues!
I have two Z3 compacts (US version purchased direct from Sony) on my family plan with the same issues of not receiving SMS or calls when connected to wi-fi, and occasionally cannot receive SMS or calls when not connected to wi-fi either. I am always able to send texts and calls, and MMS/LTE always work (I am usually e-mailed when my phone isn't working and I get that right away). Whenever the phones aren't receiving calls, it rings once and goes to voicemail, which tips us off that the phones aren't working.
If you are also getting this problem, please get on AT&T chat and ask them to escalate/forward to their manager. We've got to get their attention. Additionally, I was told that "Okay so since the phone is unlocked our service is not guaranteed to work at full capacity, also I can not submit a case due to it is not an at&t phone. "

Yep - Same problem over here. AT&T in Northeast USA.
AT&T tried everything they could (resettings connection, etc) but again also said that it isn't guaranteed to work because it's an unlocked device.
I'm doing a system repair on the phone from the sony desktop application. Hoping it will fix, but not hopeful. Now sony says they want to have my phone in for testing. :/
I'm hoping they realize soon that this is a bug, and not a case of a broken phone.

Same problem here on cricket (AT&T) in Houston. Just disabled LTE. We'll see if that fixes it like it did for the other guy. Sony needs to get on this.

Not working MMS
Yep I have tried all of the above solutions and nothing is working. Changed APN multiple times, factory reset, switched SIM, called att, went into the store.
Like above, ATT came to the conclusion that unlocked phones are sometimes not compatible with their service and there's only so much trouble shooting they can do.
I have ATT in san francisco, and it's looking like I'm going to return the Xperia z3c. Shame it's a great phone besides the MMS issue.

Confirmed that this worked on my wife's z3c. She wont miss the LTE anyway since she is always near wifi and when she isn't 3G is definitely good enough. We streamed spotify for an hour today on country roads on her phone on 3G. No issues.

sorry to hear you guys are having such issues...
My z3 compact on att works flawlessly. I swapped my nano sim from a iphone 6 i was trying out straight into this.
Att did mention something about some settings they had to flip in the back end when i switched over to a nano sim from the sim i was using in my lg g3. If you guys loose all hope have a buddy with an iphone on att and use his imei and let att configure the sim for that phone then swap the sim into the z3...could work because i know it does for me

Same issues here. I have a new D5803 on Straight Talk (AT&T). I live in the mid Atlantic. It seems I don't receive calls/texts when I have 2 bars or less. Not sure about LTE vs. HSPA. I always have Wifi on so not sure if turning it off would make a difference. THIS IS A HUGE ISSUE! Hopefully a firmware update will save us. Has anyone contacted Sony?

Thanks for the info, but this isn't a viable solution! I shouldn't have to keep Wifi off to ensure I receive my calls/texts!

Almost full LTE bar+LTE signal booster and some calls not going through?

I've been stock, Dynamic Kat, Fire Kat you name it.
So long story short, I have little to no signal in my room (2/10 calls will go through) the rest will go to voicemail and won't even give me a notification someone called. I also don't get any data or extremely slow when I'm lucky
So I tried the T mobile LTE signal booster and I can finally get data on my phone at slow speeds of 3mbps or even goes to 1 sometimes (I get 8mbps in the living room)
So now I still get random voicemails from my job or friends, I don't know how often this happens but it does happen....I always see a random voicemail without my phone ringing Wierd thing is I get FULL LTE or 4G bars
I tried using wifi preferred for wifi calling and cell data preferred and still happens, I even reseted my APN by deleting it, turning it off and taking the battery out so the APN would reset (I also added 80 to one of the apn settings, seen a thread this would help with texting and receiving mms) Do you guys use ipv4 or ipv6?
. I never had a problem like this with AT&T do you guys have any idea what could be wrong?

I kept having this problem.. Long story short.. I swapped note 4s thru tmobile and no longer have that issue.. All I was getting was voice-mails and text messages sometimes from people that called letting me know they called

Frequent Random Network Drops

I've seen a number of threads where people post about their device dropping network data connectivity, and needing a reboot to solve it.
My issue is a bit different. Occasionally (I've noticed it 3-4 times today) when I go to send a text (SMS) or to use a data enabled service like Hangouts, that my phone shows no bars at all.. not even just no data, but the bars are grey and there's a red x. I wait about 15 seconds and it reconnects, then another 10 seconds later, the data is live again.
Phone is a private sale and under 1 month old, and all the Stamina functions are off.. I do see that the "Queue background Data" is turned on, but I don't think this should effect, no?
Not sure what digits I should be looking at to know if this might be a hardware vs software issue.. build is listed as .93
Im no stranger to unlocking and flashing, but I've kept this stock cuz it's tight and I adore the battery life.
Suggestions?

Been about a month since I posted, and I'm still experiencing this issue. I often thumb my phone on and it's not connected. I don't really mind waiting for the 30 seconds or so that it takes to jump back on the network, but it often means I miss calls, and since it's my business phone, it kinda bums me out to suddenly get a VM notification of a missed call even though it never rang.
Is there some sort of utility that I can use to monitor the network activity to see how frequently it drops, and for how long? I've looked into ones on Play but they don't seem to have a history, just something that shows what data up and down is currently being reported.
Sadly the only Sony store in my city (and I think the country - Canada) has recently closed for good, so I'm not sure how to go about warranty repairs...

I don't have a solution, but I can tell you that you're not alone. I've been experienced the same thing on my Z3C. I sometimes wonder if it has anything to do with the fact that the MVNO I use doesn't support 4G LTE.

Interesting.. Your issue isn't just data, but a complete network disconnection? Im with Fido which is an MVNO under Rogers, but I thought they supported LTE. The issue also persists even on wifi

Yes, it seems to be a complete loss of the mobile connection. When I wake the phone I see gray bars and a red X on the signal strength indicator. Within seconds the phone re-acquires and the indicator goes to 2 or 3 bars. I have also seen it happen with wifi active. The frustrating part is that it doesn't seem to do it often enough to troubleshoot. I'll notice the problem maybe a couple of times a month and there's nothing obviously different about my usage patterns in those instances.

Mine does it at least a dozen times a day. I can only assume this as I frequently miss calls and at least 3-4 times a day I see it happen. =(

Same Problem
Randomly I have no connection at all but after a few seconds everything wents back to normal. Did not have this problem with T-mobile in Germany but with with O2 I have. With T-mobile I had LTE but with O2 I don't, so I guess that's the reason.

Interesting... I've disabled LTE and now have it on 3g/GSM. We'll see how it works moving forward, and I'll post again in a week. Stay tuned.

Service Providers
In the mobile network settings one can change the service provider manually. With LTE enabled my provider has three entries: LTE, 3G and 2G. Connecting two LTE fails, because my provider blocked it in my plan. Having LTE enabled, it often tries to connect to LTE I assume. I switched off LTE and set the provider manually to 3G. Maybe that helps. We'll see.

Problem receiving text messages while on LTE

I've been having problems receiving text messages while connected to an LTE network. Outgoing messages send just fine and everything else works properly as well. I was able to nail the problem down to LTE when I realized that texts were flooding in while on phone calls. This is because while on a call it switches from the 4G LTE network to the 3G HSPA network. I did some further testing by having people send messages while on LTE (didn't receive them) and then by changing my preferred network type to 3G in the Settings menu. The messages came in only after doing that.
I ditched my '13 Moto X for a One M8 last year because of a similar issue so it seems to be a problem specific to Moto, though it obviously is not a widespread issue. I'm not rooted or anything. I don't have any apps installed that could be messing with it.
I'm not sure where to go from here. Does anybody have any ideas? I turned LTE off a couple weeks ago and it isn't ideal.
