MMS not working on wifi calling - T-Mobile Samsung Galaxy S II SGH-T989

Ok so I flashed the deodexed (Whitehawkx version) stock rooted T-Mobile update with wificalling. I was super excited for it to be released blah, blah, blah then I went to send an mms. No go. Just hung. So I figured it must be because I'm on a deodexed rooted rom. I asked friend (thanks doc) who had just updated using the T-Mobile method to tey sending an mms while on wificalling. No dice. I'm wondering how many of us have this problem. It seems to be a T-Mobile issue, but I'm no dev. Just a big fan.
Thanks

It seems to work for me but it takes forever to send the images/media - unless the phone finally decided to use edge to sent the message while still connected to wifi calling. Though, I assumed once it's connected to wifi calling, it only uses wifi. Can anyone confirm this?

I can't answer that for sure. Hmm maybe I don't give it enough time, for me and doc it doesn't send until right after we disconnect from wifi. Thanks for the feedback.

This is a problem with the Wifi calling feature. It disables MMS and does this on multiple phones. I had this same problem on my Mytouch 4g as well.
There is a response from a Tmobile employee on the Tmobile support boards for wifi calling and the G2 which says http://support.t-mobile.com/message/4487.
This is normal. WiFi Calling registers through your wifi and disables the mobile networks to do so. Some T-Mobile apps have the ability to temporarily force a GPRS connection to verify you. The only away to avoid this is to disable or turn off WiFi Calling.
This is also why calls drop when leaving your wifi network's signal range. It needs to disconnect and re-register on the T-Mobile network.

i have a gs2 in one hand and a mt4g in the other. wifi calling on on both. the gs2 sends instantly without ever connecting to data, the mt4g connects to data and takes ~10 seconds to send. maybe depends on things like your router or something.

Did you update your baseband to the most recent one. That could be a problem.

You need to remember that the firewall settings are different from place to place. As an example I use a Cisco router at home and WiFi calling will connect but I could not hear the person on the other end initially. I had to look at what the router was doing, figure out what the firewall was blocking and unblock it.
It's likely the firewall at your work is letting some, but not all of the necessary traffic through. You could ask the IT guys if they can look and see what their firewall is blocking from your phone and ask them if they'll unblock it... They may or may not want to help and they may use the information to completely block your phone from being able to connect to the tmobile servers on the other side.

Is it me...

Hey is is me, or did we use to be able to send MMS while connected to WiFi and in a call?
I swear that I use to be able to send pictures while connected to to my home wireless and being on the phone until EL29 came out. I use that function a lot, but I'm starting to question myself. I've flashed multiple ROMs to make sure I was just going crazy, but it seems that every EL29 ROM I flash the MMS just says sending until I get off the phone. Then after that my 3G icon pops up with the WiFi icon still there, then the picture gets sent. I SWEAR it didn't use to be like that.
I still can send mms when on a call
I am pretty sure that I can as well. Ill have to try tomorrow and let you know for sure.
oh man. geeze. please let me know. I wanna find out what's going on
im not sure about the phone call part,
but even if your on wifi the phone still turns on 3g to authenticate thru sprints picmail servers before sending it
I can answer this one. If your on 3g and on a call, no you can't send mms. When you're on a call it knocks off your 3g to make the call. Now if you're on 4g, then you can send mms because you still have your 4g connection running. Another thing I would like to add is back when the first Evo and Epic came out, sending mms wasn't supported over 4g till Sprint made some changes on how sending mms works on their network. However one thing I haven't tried is to see if I can send mms thru just wifi with 4g and 3g off. It has me a lil curious because I know it didn't back then but they might had changed that when they changed it to allow sending thru 4g. But it could also just work on their networks only so idk..
Edit: I just put my E4gT on hotspot mode and disabled network data on a Sprint iPhone and Evo3D, both failed at sending. Soon as I enabled their data back the messages got sent. So you still can't send mms over wifi it relies on falling back to 3g. The way I recall it is the 3g comes on to send the mms then drops once it sends, but since you're on a call it won't do that.. Hope that helps lol

right, uses 3g/4g to authenticate thru picmail servers, wont do that on wifi itself. no sprint connection=no picturemail.
Connect to wifi and send a picture (while you have a signal) and you will still see the 3g icon come on for a few seconds while it sends.
That's really weird though. I really use to be able to send mms while on the phone on wifi. I swear that changed on EL29. but oh well maybe i'm just tripping out

OK so I Odin'd back to stock rooted EL29, and guess what?
I CAN send pictures while on the phone and connected to WiFi. the 3G icon doesnt pop up. it just sends. I knew I wasn't trippin. This function seems to have gotten lost among all the modding or something. But yea on a stock ROM, you can hold a conversation and send a picture...you just cant take the picture while in call. but yeah.

Incoming callson WiFi calling goes straight to Voicemail

I love the phone and having the hardest time resisting turning the phone back in. I'm on my 2nd S3 and my third Sim card. Everything appears to be going well but I noticed that when my phone is in WiFi calling mode, incoming calls go straight to voice mail. I don't get an alert or anything. If they leave a voicemail, I get that. I searched other phones that have had this issue not just the S3. I am running stock OS but I am rooted.
Can anyone else verify that there incoming calls are working on Wifi Calling ? Any ideas on what I could try ? outgoing calls work fine.
EDIT: Sometimes calls go through, sometimes it doesn't. When it does go through, I can't swipe the green button to answer. It goes through the swipe motion but nothing happens. When I am off of WiFi calling, I can receive calls correctly and I can properly swipe to answer them

Ah-ha, you just solved a mystery for me! I like to have my phone automatically connect to any wifi in my usual hangouts to save data. I kept wondering why I was missing calls without hearing my ringtone. I have a theory on what is happening. Back on my old Vibrant, wifi-calling could not work on slower networks. I could get it to initialize but never could it actually make a call. I noticed this when up in the mountains at a lodge that had very slow internet. Maybe it's the same issue? Hopefully others will chime in.
Not sure if this a slow network issue or and ICS issue. My S3 does this also and is frustrating since I auto connect to wifi at home and work. Keep missing damn calls. My S2 started doing the same thing when I updated from GB to ICS. Maybe its a Samsung and ICS thing now that I think about it because the wife and kids all run ICS on HTC Amaze without issue.

Disappointing. Are you on T-mobile? (I expect yes as this, to my understanding, is the only US network licensed to use wifi calling?)

I think most of these threads are locked because XDA is trying to separate them all. Anyways, this is the only way I could respond. Since my first post, I have had more positive experiences with wifi-calling. I think it may be a little of both, slow connection and this newer implementation. On a slow connection it definitely wont work correctly which is what I would expect. What I mean is you can't successfully answer or make a call as the phone app will just hang. Going straight to Voicemail is another mystery altogether. I have 4g internet at home so there is no reason I can think of for that to happen. But like I said since my first post I have successfully made and answered several calls from home using wifi-calling and even a few from a location that had decent internet. Call quality was decent for what it is.
Guys, take a look at this thread. It concerns wifi signal dropping and re-enabling. That would certainly explain why some of the calls made to me when I was at home on wifi went to Voicemail even though I have 4g. I did notice some of this last week.

This happens on sprint phones as well...
I see this thread is open again. My experiences with wifi-calling have bore out what I thought: A weak signal will cause problems. I only wish that every call went to voicemail. What happens often with me is that wifi-calling will partially work, as in I can answer a call but the person can't hear me at all and I may catch one or two words from them. If they terminate the call, the phone app is fine, but if I terminate the call, the phone app hangs and freezes everything! Today it was so bad I had to pull the battery and reboot. Maybe wifi calls going to voicemail is an imperfect function that Samsung or rather T-Mobile built into the app. It kinda makes sense as this app could never complete a wifi call if you were connected to slow internet when it was a separate app. In any case I would rather have my wifi calls go straight to voicemail (and get a pop-up notification) than have the app try to work but wind up hanging my phone. What do you guys think?
I don't know about slow networks. I've already exchanged one T-Mobile S III because of Wi-Fi calling problems. My replacement works much better on my work network than it does on my home network and it is much, much slower than my home network is.

This isn't particularly good news for me. If it isn't software problem that manifests when coupled with a slow network then a future update won't fix it. That's what I was hoping the problem would turn out to be. If its hardware, then the time I have to do something about it is limited as I dropped my first phone and the replacement has a limited warranty, I think. Plus, I've paid to have invisi-shield placed on the front and back and would have to eat that cost if I get another replacement.
Epic Fail
I have this issue and am at my wits end to resolve it. Wifi calling is a major feature that worked fine(except echo) with my Vibrant. However, nothing I have tried will fix my ability to answer calls on WiFi. I have the SIM from the GS3 box. My E911 address exists since my bb8900. WiFi Power Save is off. All routers I use, Linksys E4200 and Linksys WNR1000, Linksys 614. Wireless N and G. T-mo CS could not help. I understand that the WiFi calling changed from UMA to IMS. No separate app. GS2 users with same issue. Anyone with a clue? Please help.

how did you turn off the wifi power save?
I experience the bad quality calls on wifi, at my workplace it is perfect, but at my home, its terrible.
my home network is faster than my workplace.
I think this is something to do with the firewall as well.
and I couldn't find the way to turn off firewall on the dam verizon fios actionnet router.

you can also try to broadcast the wifi on channel 3 only, that helped me in my case.
WPSM
There is a link earlier in this thread to another XDA thread. Phone app --> *#0011# --> menu button --> WiFi--> Press WPSM On/Off button.
My GS3 would drop a WiFi signal 3 inches from the router at work and 3 feet from the router at home. At least THAT is fixed now. However, I don't seem to get the same WiFi signal range as my Vibrant did using the same routers Trying the channel 3. I do have a few setting set to auto at least on my home router.

Yes, that's required, but not the underlying issue of the thread.
I've had wifi calling weirdness too. I called my sisters Verizon cell and there was no tone but after xx seconds it got her voicemail. When I call my phone on my house phone (Comcast) my phone rings but there's no tone on the house phone!
I NEVER get a ring. Just someone picks up our voicemail does.

They can't hear me - wifi calls

Been having some issues with callers not hearing me. I tried swapping out the modems (can't remember exactly which ones but can figure it out if necessary), tried different kernels (while I was on TeamSonic rom), and switched from Sonic to FrostyJB and still happening.
I am on wifi calling at my home (crappy signal). It happened on all calls this morning. I made all the above saps and changes this morning as well. I tried a call when I left and was outside of wifi and call worked fine.
This sound like a defect or setting thing? Don't see a lot of settings in the Wifi Calling menu.
Thanks!
There are a few things that could be the problem. You need to determine if it is the phone or the wifi.
What kind of signal are you getting? Are you able to test your wifi for internet? Is this all of a sudden, meaning were you able to use wifi calling without problems prior to this recent problem?
I always had problems with wifi calling so I never use it on my HTC one s and this one too

It has been happening more frequently lately but I am not really sure on a time frame. I don't make gobs of calls. I have had the phone for about a month or so and didn't have any problems early on. I have tried a few different ROMs but I wouldn't call myself a flashaholic.
My wifi signal at home is pretty decent. My speeds are usually around the 18 - 19 range. No problems with internet. The calls connect pretty quickly.
I do have a cell-fi (sp?) unit on the way from t-mobile which my help but I would just like to try and figure out if something is off with the device.
Thanks!
Information update:
I just made a call from my office (same no cell signal and decent wifi) and call worked fine. Wifi speeds here are a bit slower, usually around 8-9.
Haven't changed router or modem at home. Time Warner Cable is the provider.
Will check my son's phone tonight. He also has the S3 but being a teenager, I am not entirely sure he knows how to make an actual phone call...
Does the problem seem to happen at the same times of day? Depending on how your isp is set up, heavy network traffic can cause the issue. Also remember that your voice going out is like uploading a file on that upstream data is going to be slower than downstream.
Is your cable modem or router kind of outdated? Last year I upgraded my modem and saw a huge improvement. The DOCSYS 3.0 tech is a lot faster than a DOCSYS 1.0 rated modem can handle.

Today it happened around 8:00 am (EST) and again around noon. I'll check the upload speeds as well.
I swapped out the modem about 4-5 months ago. Not sure of the make. It is the one Time Warner provides. Haven't noticed any major problems with our PC though.
Router does have a few years on it.
I suspect that you're getting one way voice translation... the router is forwarding the incoming voice traffic to your phone but failing to do the same for your outbound traffic. I have a Cisco enterprise class router at my house (I'm an IT geek so I *play* with it) and until I opened up a bunch of ports to a bunch of sites I saw being blocked in the router logs I was having the same issue.
I asked T-Mobile for a list of voice gateway IP addresses at their end but none of the tier 1/2 techs were ever able to give me any useful info regarding IP addresses or ports... The phone keeps finding new IP addresses it wants to connect to so in the end I gave up on getting wifi calling working reliably and have mine set to prefer cellular.
A SOHO or Home router ought to automatically open up the necessary ports but I would suggest looking at the manufacturers web page to see if there's a firmware update for your router. If there is, apply it and see if that fixes the problem. Else buy another one and see if that resolves it. If it doesn't then you can always take it back.
Hope this helps
I thought it was just me that had a wifi problem
One thing to keep in mind is you HAVE to have a cell connection to use wifi calling. It's possible the signal is so weak it's dropping once you have the phone up to your face and it's moving around and stuff. Try using speakerphone with the phone on the desk or wherever you have some signal. You should also try to get a signal booster from tmo.
Definately check to see if there's any firmware updates for your router like ronin said.
Is it a G or N router? If it is N, check your other devices that connect to it as well. If anything connects to it at 802.11G then all connections with the router can be throttled down to G speeds. If so disconnect the G device, reconnect your S3 and try it again.
Also have you restarted the modem and router recently? Unplug them both from power for about 15-30 seconds. Then plug back in and give it a minute or two for everything to reconnect.

I didn't know about the cell connection requirement. The cell signal at my house is far north of crappy but the signal in my office is bad as well and no issues. I do have the tmo booster (cell-fi?) on the way. Hopefully that will fix it.

I believe you are right on. I could not get my Wifi Calling to function properly at work. Text works great, sending and receiving. My phone rings when I receive a call, but I cannot hear anything, neither does the caller. Similarly, when I dial a number, the other phone rings, but no audio is heard on either end. I called TMobile Tech Support and they read me a memo from Samsung that this is a "Known Issue" with "one-way audio" on wifi calling. A salesperson in the store read to me the same memo. Interesting thing is when I got home, everything works, both voice and text. I tried it at another wifi location and everything works also. But not at work. I am convinced it is a problem with the network at work. Puzzle is that Wifi Calling works great on my HD2 with Custom Rom at work using the same enterprise network. But I would hate to keep swapping the micro sim from the S3 into a sim adapter into the HD2 just to get reception at work. I was hoping the upcoming JB upgrade will solve the problem, but reading the above explanation makes me worried now. Anybody out there with any work around?

I believe you are right on. I could not get my Wifi Calling to function properly at work. Text works great, sending and receiving. My phone rings when I receive a call, but I cannot hear anything, neither does the caller. Similarly, when I dial a number, the other phone rings, but no audio is heard on either end. I called TMobile Tech Support and they read me a memo from Samsung that this is a "Known Issue" with "one-way audio" on wifi calling. A salesperson in the store read to me the same memo. Interesting thing is when I got home, everything works, both voice and text. I tried it at another wifi location and everything works also. But not at work. I am convinced it is a problem with the network at work. Puzzle is that Wifi Calling works great on my HD2 with Custom Rom at work using the same enterprise network. But I would hate to keep swapping the micro sim from the S3 into a sim adapter into the HD2 just to get reception at work. I was hoping the upcoming JB upgrade will solve the problem, but reading the above explanation makes me worried now. Anybody out there with any work around?

You'd have to have access to the networking equipment at your work to really know the answer why... Short version is that Home routers/firewalls reflexively open ports when a device inside the network tries to access an IP address. UPnP is an example of this... Enterprise class routers/firewalls don't do this as it's considered insecure. So, you have to know what ports the traffic is coming from/going to and allow traffic on those ports. You also want to know what outside IP address it's destined for so you can lock down that traffic to just certain destinations, not the whole internet...
So, if it doesn't work at your office then there's likely very little you can do to fix it unless you're in the IT department or have a really good relationship with the Network Administrator of your IT department.

One thing to keep in mind is you HAVE to have a cell connection to use wifi calling.

Lol, really? Show me evidence of this.
What would be the point of Wifi calling if you have a cell connection? I've used Wifi calling since my MT4G and that's a total crock of BS
There would be NO POINT to Wifi calling if you have a cell signal.. common sense...

Note II drops WIFI Calling??

Hey I'm a 1st to T-Mobile i'm testing it out before I switch all my lines from Verizon. The question I have is that both the Note II and the GS3 that I have seem to drop the Wifi calling feature randomly. I thought at 1st it may have been some sort of power saving option but it seems to happen in frequently. (Doesnt matter if I'm close to the Router or not)
Is this common? Or am I the only one that has had this happen?
Thanks for any input!

I'm not sure what you mean by turning the App off? When turning the WIFI calling app off does that not mean you are unable to use the feature?? LOL- I have to have this as I have zero reception at my home.
Thanks for letting me know!

@ scoob go to setting, more setting, deselect the wifi calling app and it should work for you my coverage at my place is between 0 and 1 bar so this should help

mine goes on and off on both my new note 2 and my wife's new galaxy s3. really aggravating. worse on my phone, when in wifi calling, it only answered calls like 1 out of every 10 times, otherwise they went to voicemail. I took the sim out of mine, then put it back in and pushed it in and out and in the holder a few times and now it seems to receive calls in wifi mode but still always in and out and error to connect and such.
My experience with Wifi-Calling has been nothing but troublesome. It's really not reliable at all, sometimes calls comes through sometimes don't.. and when it does come through I can hear the caller but caller cannot hear me. This is quite common problem with wifi-calling and i given up.
If you get even a 1bar of reception near by the window, I suggest calling T-Mobile and getting their Cel-Fi device (Free of charge but has to return when you leave T-Mobile). 1~2 bar by the window will give you full 4bar reception throughout the house on 4G. Only requirement is that you must be living in single house, can't ship out to house that are connected by or close by. I live in townhouse and I just told them I live in single house and got the device in 3 days. =)
Wi-Fi calling is a disaster. For me, incoming audio drops constantly, but the party I am calling can hear me fine. On other occasions, the call will just randomly drop. Came from a Sensation where Wi-Fi calling was perfect. There does not seem to be any resolution... I have spent hours talking to tech support and they have replaced the device with no improvement. I have also had my ISP out and they have verified that my connection is fine. I have even changed the router out... same issues.
With my wifi calling, as soon as I turn kt kn my bars at home would drop where I would hardly get any service. As soon as I turn wifi calling off I magically get bars. So I leave it off and now I get bars pretty much everywhere I go....almost

With wifi calling on, it's suppose to drop signal bars to nothing. You have to go by the wifi bars instead.
Wifi also greatly depends on your network conditions. Cause I have the same problem but it doesnt happen to me that often after some tweaking.
Wifi Issue
I have that problem quite a bit but the signal strength on my router is good. Yesterday i had my internet company reset the cable modem and my wifi problems have decreased a lot but it is still happing. It has to deal with the wifi certificate problems on the Note 2 (Samsung). It is the same problem that I had on the GS3.
Oh well

Uhh, that's the point of wifi calling, to make calls over WiFi and disable your cellular radio. If you turn on Wifi Calling, you should get a blue phone icon on the top left and your "bars" should drop to nothing as your phone turns off the cellular radio. You can still make/recieve calls/sms/mms.
I've been getting an ER01 error lately with invalid certificate, but it seems to be a T-Mobile backend problem? It happens, about 10% of the time and only on my school's network (I have a feeling, it might have to do with the sign in process there).Otherwise, it works well at my apartment.

i get that certificate problem at my house, not too much anymore, but I still see it. and the wifi calling does drop in and out at various times. not a huge deal for me, but the average person wouldn't deal with that.

I've been noticing more & more problems with my service in the last two months. I called T-Mobile to fix it and whatever they did seemed to only help a little. I get times where I get frequent ER01 errors with WiFi & duplicated text messages (same text message gets received by my phone 2-3 times) for an hour or two. I used to also get errors sending texts around that time, but that appears to have gotten better.
Someone else mentioned Uverse, and my WiFi calling problems are at home & work, both of which have AT&T for internet... When I switched from their DSL to Uverse I expected less problems, but got more.

Seems to be a problem that a lot of people are experiencing. Just did a quick Google search and some indication points to a possible T-Mobile back-end problem. I wonder if i call up T-Mobile and ask for wifi calling to be explicitly added to my plan if that'll change anything.

Tmobile MMS

Does anyone else have issues sending and receiving MMS on Tmobile while on wifi? I do have wifi calling enabled but turning that off doesn't help. MMS goes through fine if I turn off wifi and use network data instead, however.

I was having trouble receiving MMS after using the T-Mobile tethering fix listed here: http://forum.xda-developers.com/showthread.php?t=2715450
And this fixed it! Thanks!!

Was having the same issue and solution (use HTC's native messaging app). I just tried the fix that nycebo suggested and it worked. BUT, sending a pic was pretty slow. So slow that I thought it was going to fail (same symptom as when it was failing to send). Eventually it went thru and I'm also able to receive pics.
Hopefully, this resolves group messaging which is basically MMS as well.

Turns out the culprit actually was wifi calling? I turned that off and now I can send mms.

As I mentioned earlier, group texts are handled as MMS's. Last night the M8 was put to the test. Had an issue come where the wi-fi was partially to blame. Group text consisted of 6 people with a sprinkling of pics attached. Some of their texts and pics were getting thru while some weren't. I was on wi-fi and there is a 4-5 bar LTE signal in my area. Wi-fi calling is set to cellular preferred. Not only did some of the texts not come thru but the ones that didn't were also separated out from the group thread. I hit the download link and nothing. No error message. Nothing. Just went back to "Download message". Granted this was on the locked APN. I switched to the custom APN. Still nothing.
This worked before so I try again. I turn off the wi-fi. BAM. All the texts of the separated out people start coming thru AND they get put back into the thread.
So yes, the culprit is wi-fi but I've had wi-fi on on my Note 3 and this was never an issue. Also, in the middle of the group texts, I swap the sim into my Nexus 5 using Hangouts with wi-fi enabled and there was no problem there.
I think the root cause is the way HTC's Android implementation is handling the switching between wi-fi and the carrier network. Seems to me the message should try sending via wi-fi and if that doesn't work use carrier network. I don't know enough about the protocol to say this is for sure the case but that seems to be a logical explanation.

Curious if this is still a problem.
I am getting a GPE this week, but I need to be on wifi only at work all day and get MMS/group MMS
GPE doesnt have the option to use stock messaging (I assume Hangouts only, which I have seen has known issues MMS via wifi)
Will I be able to get MMS/group messaging on wifi only (wifi calling enabled) ?
Use Textra until Hangouts gets this working ?
