anyone can receive/send MMS while WIFI on?

im in nyc currently running OMJ 2.2 v3.0 rom with Stock kernel. But my issue has been happening since before I rooted my evo. The problem is I cant receive MMS during wifi is switched on then have to switch wifi off and wait about 20 minutes in order for the mms to download so I can view it. I called tier1 and 2 and tier 1 just made me factory reset my phone or clear cache on the mms app in settings which fixes it for about 2 minutes before I turn wifi on again. Tier 2 told me that theres no way I can receive and send mms while wifi is on so there goes my issue...I never had this issue with my apache, mogul, diamond, tp, tp2, BB bold.
The error msg I get is a transient error failure...please can anyone test their device and turn wifi on and try to receive and send MMS and let me know if its successful so I can send this to sprint b/c its totally oblivious I have to turn wifi off and wait 20 minutes and then have my mms download w/o errors.
Thanks in advance

No one?

My texts go through with WiFi on.....no problems. I probably send 50 texts a day while connected to WiFi; if not more.

Currently MMS uses your data only. You will notice that when sending MMS your 1x/3G icon shows up next to your wifi icon.

no the 3g symbol doesnt show up next to the wifi signal when trying to send/receive mms...

My 3g icon pops up when sending/receiving MMS when I have wifi on.

Could be your ROM. Have you tried different Roms?

No problem here getting or sending mms texts, email, even browsing the web on the phone while tethered or wireless.
Fresh ROM

[Q]sending mms via WiFi ?

something i have noticed is when sending pic messages from home on wifi is not working. If i have wifi on my phone will just say sending for ever. if i turn off wifi and the 4g pops back up then the pic gets sent. i dont thing i have any toggle set. I do not have llama on the phone. So my question is does this phone send mms over wifi or just over the network?

am i the only one with this issue? i did a phone exchange a week ago and I noticed the new phone had the same thing so two phone same experience...any ideas?

How is your signal at home? U can't send mms over WiFi, only data

Mine will send while connected to wifi.
Using tapatalk on my Galaxy 2 to post this!

Mine sends MMS when wifi is on also. I would only have 2 bars and on edge and it still sends in like 20 secs

Im having the EXACT same problem with you. I have the tmobile version model, SGH-T989. I got online with a rep at tmobile for 2 hours trying to resolve this. After a point she said galaxy s 2 doesnt have voice chat over wifi which I didnt understand what that had to do with not being able to download or send attachments via mms. She basically said you have to have data enabled in order to send and receive pictures. I was pissed because my brother's mytouch g is part of my family plan, and he is able to receive attachments while just being connected on wifi. My issue is that I only have edge, not even 3g connection at my home. I don't know what to do. I searched for apps to fix this. But no luck. Anybody else tried fixing this?

Your brother can receive them while on wifi, but not "over" wifi. It has to access data to get mms. You'll see data turn on when on wifi when a pic is coming in.

MMS not working on wifi calling

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.

Mine will not mms on wifi either. It doesn't even send once you get back on cell. It just says sending. My vibrant was the same way!! Fck! Annoying!

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

I think you're trippin. Hey maybe you should Odin back to a previous software to test it out and let us know! Lol
Sent from my SPH-D710 using XDA App

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.

Can you text over wifi instead of sprint network????

Sometimes at home can't get damn 3g signal. So I got wifi how do I send messages using wifi???? ****'s very annoying.

Text is a voice service it doesn't use data at all. If you can't text making/receiving phone calls must be hard at your home as well. Over wifi Google voice or a similar app from the play store would be your best bet

Yes, you can. The best way to do it would be Google Voice, but there are other apps out there capable of it. The way the carriers handle it (in this case Sprint) is over the network... GSM or CDMA. 3g is always an extension of the mobile voice network... this is why you typically cannot make calls and browse the web while on 3g (although Sprint has found a way to defeat this with the Viper and the Evo LTE, though a second chipset). 4g runs on a different band than 3g does, which means it doesn't affect your calling / text capabilities.
I know that is more info than you asked for. The long and short of it is that you need an app designed to run on Wifi, rather than mobile data, but it is possible.

+1 for google voice. I even use it to text from my Nook which doesn't even have 3g.

G voice.. or complain to sprint and get a airave and hook it up to your wireless router and have signal in your house .. or get roam control (assuming your rooted) and roam when your home and use your wifi for your data needs and sure youll be fine since wont need to worry about sprint and data roaming

Uh, slvrap1 already stated this in so many words above. We're discussing workarounds now. And yes, Google Voice is the easiest way to go if you're using an Android phone.

A lot of the information in this thread is wrong...
SMS is actually a function over 1xRTT (just like voice calls) not EVDO (3g)... This is why you can recieve sms messages while on a phone call but not get other data services at the same time...
You never make a phone call or transmit SMS messages over EVDO, it is a data only connection protocol..
This is why SMS are limited to a certain number of characters, because they are actually a hack of the control channel in 1xRTT communications...
Simplified version:
REAL SMS is a hack of the control channel between cell phone and tower. It has nothing to do with a data connection so it can not be transmitted via EVDO, WIFI or any other data connection...
Note: When I state REAL SMS that is because services like google voice and others are all VOIP connections that use data connections to transmit messages and phone conversations... There is character limit in VOIP texting but they impose it because you can send it to a REAL SMS and that has character limitations built in..

Correct. Texting has nothing to do with 3g. You can find an app that can use 3g or wifi to text o stead of the network. This is what my friend uses on AT&T so they don't have to pay for text messages. They use the network.

That actually just sends the message via the data connection to a server, which then relays that into the carrier's system and is then transmitted to the recievers phone via the 1xRTT control channel... They aren't actually texting a phone, they are sending an instant message to a server that then knows how to convert and relay that into a text message.
Note: I use 1xRTT because we are on a CDMA2000 system... for AT&T, T-Mobile and other GSM it works on their *2g* voice connection... I forgot what it is called at this moment...

Use roam control at home, Verizon probably covers you better. 1x roaming is free other than your minutes

Well let me say this. I was at a music festival in March. Had some signal bars but could not make calls or texts. Incoming or outgoing.
When I was in a certain stage I tried again (text) they all failed. I tried to turn on wifi and found an open network! Tried to text. Success!
So in my experience I say yes! Anywhere else I could not text. So when I needed to text I would return to that stage and connect to wifi.

More likely when you moved you connected to a less loaded tower, being connected to wifi was just a coincidence.

Well if you are connected to WiMAX or Wifi.. yes you can make a phone call and surf the web at the same time.. If you are on EVDO, the only way that is possible is if you have 2 cell phones... One to surf the web and one to make calls

Your experience is only coincidental... It is physically impossible because the SMS system is built on the 1xRTT control channel... It has nothing to do with the data connection in any way shape or form... It is a hack on the tower identification and protocol transmission channel.
It is like if you take out a frozen piece of meat, turn on the microwave and leave the piece of meat outside the microwave (never put it in the microwave) and claim the microwave is defrosting the meat...

Are you reading? He obviously cant text at home.. he did say 3g but probably doesnt know what HES talking about.. i think its safe to say hes getting NO signal since he is unable to send text messages.. thus want other options to send text messages which people are giving.. he doesnt care how the network works and how it uses 1xrtt and not his 3g radio.. he just wants optiong to improve him sending messages at home which no matter how we put it, theres only a few options we've already determine which is 1: google voice or other voip messaging app. 2: using roam control to make sure he has signal to send it regularly while roaming. 3: can get airrave and hook up to his wifi at home to bost his signal inside of the house. 4: leave his house and go walk around til he can send one lol 5: someone said theres apps which allow you to send it over data which then gets converted in the tower and sent as normal.. good luck OP!

Google voice will only allow you to text over your google voice phone number... If you use google voice to manage your SMS and text using your phone number, it will still send it via SMS (1xRTT control channel) and will fail There is no alternative when you want to use your actual phone number except for utilizing the sprint web tool.. log into your account and send a text message from the web tool.\
Note: I am one of those people that will correct wrong information if i see it, even if it doesn't 100% pertain to the original post. IMHO it is the only way to ensure people don't start repeating the wrong information and exponentially make it harder to teach people the correct answer.
