[Q] MMS will not download!! (AT&T)

Hey guys, (Did extensive search before posting this)
Whenever I get a MMS the messages show a download button but will not download. I have tried turning wifi on and off, turning mobile data on and off, rebooting, using stock app and Go SMS and nothing is working. I looked in APN settings but do not know if they are right or not.
The issue just started recently, I have had the phone about a week and they seemed to work at first.
Please help,
This is driving me crazy and is frankly unacceptable in 2012. I saw some threads about old Galaxys having this issue.
You have to be on mobile data without wifi for them to download.

Thanks for the reply, but I have tried turning wi fi off, which in turn reverts to mobile data and still no success. Could it be that I also use a micro cell? My carrier service is literally the worst possible at my house without the micro cell. This is quite unfortunate if so.
I think wifi has to be off when it is initially coming through and yes, a micro cell will do it. Is it a voice micro cell or data?

Its a voice micro cell, but it also transmits a 3G signal. Not sure of the speed since I always use wi fi.
This is boggling my mind. Are you telling me that it is not possible to recieve a freaking MMS message created in 1982 (sarcastic) on a 2012 LTE device if I am in a wifi network. WTH. That is crazy to me.
So are these images gone or do I need to turn off wifi and turn off the micro cell to download?
Thanks for your help btw.
So I disconnected wifi and disconnected my microcell and clicked download on Go SMS and nothing, error message. Pulled up the stock SMS app and clicked download and after a half minute or so the picture appears. The picture then also shows in Go SMS.
I guess the solution is no MMS while at home which is a bit frustrating coming from another device/platform where this problem would not occur.
Thanks again.
I have the international GS3 on AT&T. My phone automatically downloads MMS if only mobile data is on or both wifi & mobile data are on. I believe it is your microcell causing your disruption OP.
Sorry, my international S3 also only downloads MMS if only mobile data is on.. I have yet to see it auto download when Wi-Fi was on. I would say it could be the microcell in this case though.

Weird. I am on T-Mobile though and my galaxy nexus was the same way.

It isn't just you. I had the same issue with my GSII. It would randomly appear and disappear. Have the person resend it.

Not true. I am on WiFi 90% of the time and I still get MMS

When mms comes in the WiFi should temporarily shut off and the radio picks up 3 or 4g in order to download it. U honestly won't notice any seperation. If u honestly can't receive them, check your apn settings

You are getting mms when you are away from your home/microcell, correct?
hmm, i just noticed that mine has been doing this lately too. MMS won't download unless I turn off wi-fi. I'm on t-mobile

WiFi issues!

Hello i just bought the galaxy s3 the last week.. i noticed that it gets connecting and disconnecting very often! Every 5-10 seconds does thatat.And the signal is weak compared to the iphone 4 same location ..i mean the router is 5-6 meters far away and im getting 2-3 signal bars but on iphone i have full signal!
Are there any ways to fix the disconnecting/connecting issues?
THANKS.

Mine is the opposite the minute i switch the phone on it locks onto the WI-Fi straight away.
Try a factory reset and perhaps that could do the trick

Mobile data in JB

I am having problem in accessing mobile data from day I started using JB leaks. I am getting H+ signal but not internet. It works some times. May be it's just coincidence. Is anyone having this problem?
Sent from my GT-I9300 using xda app-developers app
i dont believe there have been many threads reguarding your issue....of having a network but with no internet.
i assume you have run down the typical trouble shooting
APNS
MODEMS
ECT....
Oh, and when you switch back to ICS does it start working agian?
APN looks fine.
I am using the Odin version of LI5.
Going back to ICS - Naaah. ...

I'm having a very similar problem on my UK handset on orange running latest jellybean Rom.
There are times when I am trying to load an internet page or xda subscribed thread for example and the phone shows full signal and the data is switching between 3g and h+ on and off and the arrows show nothing happening or data transfer.
I normally end up exiting the page/app and restarting it.
Is this a modem problem? Do I need to flash a different one?

Battery drain? - Wifi and 4G?

Hi guys,
Ever since I've moved to a new place, my wifi disconnects every 10 minutes of use and connects again right away. Not only that my 4G and Internet constantly disconnects and connects because of the bad service in my neighborhood. Would this contribute a huge portion of my battery drain or is it minuscule?

Wifi Tethering Tmobile Tracking

hi everyne,
Im using a rooted vibrant (vanir rom) with unlimited data plan for almost a year now but 75 percent im using a home wifi per month.
1.Can Tmobile detect from my account if i suddenly use a wifi tethering service from a 3rd party app for my tablet?
2. whats a good wifi tethering app that is noy detected by tmbobile?
Sent from my SAMSUNG-SGH-T959 using xda app-developers app
The only thing they can detect is that you use much data traffic in short time and has many connections opened. I don't know if they use normally a sniffer. If they do it, they could see depends on the data and signature, that it is not from a mobile phone.
