[Q] Weird Mobile Data problem - Galaxy S 4 Q&A, Help & Troubleshooting

So I flashed a rom(samy deluxe) and suddenly i see I can't use mobile internet. I have good signal but still I couldn't use internet. So i did a full wipe and went back to stock rom. Now I still have the same problem. I notice my messaging and calling doesn't also work properly. I can send messages and recieve messages . I can call I can recieve call but sometimes it doesn't . Like someone sent me a message at 10 pm but I recieved it at 3 AM so I was confused. But Mobile Data never never works. I tried flashing a new modem. I tried setting the APN but it just doesnt work. I see the mobile data letter(H+or E) but it just doens't work and I really don't know why.

Mmm...

Unable to SMS after loading Modaco 2.9!

Hey, im failty new to the rooting scene, im usually happy with what comes out of the box but i decided to give this a try.
Everything went fairly well, had a few hiccups but in the end i got Modaco 2.9 on my Telus Hero. The only thing that doesnt work is SMS.. i can't send them and i can't receive them.
I double checked my APN settings and everything is fine, can anyone help me out?
Did you update to the latest radio?
yeah
update-hero-radio-63.18.55.06IU_6.35.08.22-signed
can you make calls? sms are not connected to the apn settings or something that has to do with internet or data network at all. sms are sent in the signaling with the network, the only thing that has to be set right is the smsc address. did you check that?
yeah i can make and receive calls, i can even do the 611 to contact telus
i checked the service number, its there. Im going to call Telus and ask them to push my config on my phone again.. i had to do it yesterday because my internet wasn't working on my phone.
Hope it works
Update: Called Telus, basically i can send txts but cannot receive them, according to the SMS server, it reaches my phone but isn't notifying me i guess..
i tried, re-wiping and re-installed rom and radio and still nothing.. everything else works great.
EDIT: oops sorry for double post, firefox crashed for some reason :S

SMS and Internet stopped working

Really annoying me... texts and the Internet no longer work.
Did not do anything, and yet they have just stopped working. Reset the phone to default, entered in the correct settings for MMS, WAP, Net again, and still does not work... yet i can make phone calls and receive texts.
Whats going on? sure someone else had this problem...
Cant say I have had this problem myself,I dont mean to be rude but have you checked the settings page>mobile network settings> at the top there is an option to turn on or off mms and data (I know cos I use it to control usage).As for the sms problem Im not sure.Do you use the stock sms app or something else?
Also what network are you on?is it possible your apn is not correct or selected?Sorry for asking all the seemingly obvious questions but its usually where I would start with the same problem.

MMS data/attachments 2.3.4

2.3.4 HKTW - Rooted
It seems I can't view/download MMS attachments. I can send and receive normal SMS just fine. However, when I receive a MMS, the download button is there, but it just times out and doesn't receive anything.
I've messed with APN's, double checked SMSC. Tried using a different SMS/MMS client (GoSMS), just can't get it to work.
Is anyone else having this issue or have any ideas?
(I'm aware there are multiple threads about people not being able to SEND mms, this problem is not the same)

which flash method did you use to install 2.3.4. there seems to be alot more bugs associated with the cwm method, than flashing via fastboot. I have not experienced any problems with mms on 2.3.4.
Is your mobile data on? You must have mobile data on, NOT wifi or anything. You probably do, but this happened to me once and I realized I had a widget that turned data off haha. Hope this helps! If it doesn't, maybe try looking around to do the cleanest install possible of 2.3.4 and see if it helps that (and any other bugs you might have)
Also, you didn't mention, can you send MMS? You just said you can send/receive SMS and can't receive MMS, but what about your sending?
I originally tried the CWM flash, but got nothing but boot loops. So, I then flashed a fresh 1.8.3 SBF and flashed 2.3.4 via fastboot.

Mobile data is on. I can use data via 3G. And, it doesn't appear that I can send MMS either.

I see, sorry that didn't help. I'm not sure what else could be the problem so I'm no longer able to help much...just to cover the basics, have you tried rebooting? Are you using the stock app (other than when you tried GoSMS to test the problem)? Even if data is on, are you actually in a 3G area (i.e. can you use the browser, download apps, etc.)?

I've rebooted several times throughout the day. I can use the 3g connection just fine for web browsing and using the market.
i had this issue too, thats why i am back on froyo.

SMS wont work after installing CM7.2

I installing CM7.2 and SMS no longer works.
I have tried,
installing new SMS program.
Going threw settings but cant see anything out of the ordinary.
Changing the SMSC to the one for my carrier both in normal format and in PDU format
rebooting after every change
going on telstra website and asking to be sent the settings
Oh re changing the settings in baseband switcher
Nothing works, Is it as simple as something is disabled?
I wish I could find a rom that would work without crashing or things not working!
I had problem connecting to Telstra 3G (see: http://forum.xda-developers.com/showthread.php?t=1634366#). But works fine on 2G. Is this similar to you?
connects to 3g fine. Just wont send SMS messages. It hasnt sent one all day but I made plenty of calls and been on the net. Whiterabbit I had a little trouble with network not connecting when I disable juice defender but could call and send SMS.
Looks like its back to ICS again! I dont use the camera at all so thats the only problem I come across.
ok wont work on CM9 as well what the hell is going on? the SMSC is right so it cant be that!
Maybe telstra SMS service is down?
Ok put my sim card into my old sony ericsson cedar and it wont send.
Should of done that first now I flashed a ROM for no reason

:D Very good
Ok I rang telstra and they reset the account all is working again. The service people dont have a clue. They didnt even know how to get into change the SMSC number, Lucky I did if I didnt there would be no way I would find it. It was right anyway and they gave me the +61 number that doesnt work on androids lol no clue at all.
Now I have reinstalled CM7.2 again! telstra are a pain in the arse.

No mobile networks detected

Today for no reason at all i became unable to make phone calls or text messages. The error message was stating no mobile networks detected, however i'm showing i'm connected to LTE with nearly full signal. When i roam phone calls and text messages work.
I'm rooted, MF9. I was fine yesterday, and no changes have been made.
i'm using philz recovery. I have wiped the phone "prep for new rom" and flashed a fresh stock odex rom and there wasn't any change.
LTE data is working but phone calls and text just won't work.
Edit- Also just to note i have 4 other guys in my office with Sprint Galaxy S4's and none of them are having issues.

I am having the same exact issue. Airplane mode toggle fixes it but unless you are trying to make calls or send texts you are unaware of the issue, which poses a problem with receiving calls and texts.
Notification bar shows full service and data, and the data continues to work, but the mobile network is "unavailable" for texts and calls.
I've tried reflashing the firmware (on MK2), updating the PRL and profile as well as reactivating the phone. What else is there to try?
Sent from my SPH-L720 using XDA Premium 4 mobile app
Call tech support
Try this
