Hello fellow S3ers! I am David and I am new here.
I seem to be having a strange problem with my data network connection: My S3 is with Verizon and I have had it for several month now.
This morning everything was working fine down in FL and I hopped on a plane, set my phone to airplane mode, and returned to Philadelphia. After landing and disabling airplane mode, my phone refused to connect to any sort of data network - no 4G, 3G, or 1x. Calling and txting works fine.
I have been searching for a while now with no success. But here is the strange thing: I went into About Phone > Software Update, and clicked "Check now." Low and behold, the 4G icon flashed on and downloaded the latest update! (Which was over 140mb).
The phone updated and restarted, and now it says Software up to date. I saw the 4G icon flash on for a moment after the initial update restart, and then it flashed off. I went into software update again, and clicking Check Now caused the 4G icon to turn on again! It immediately turned off again, however. I was able to repeat this cycle several times, but now the Check now button does not turn the 4G back on at all - even for a moment as it did 10 minutes ago.
Any ideas how to solve this issue or what is going on?
Please let me know if I can provide you with any additional settings or details, but here are some details that may be relevant:
Mobile data: checked.
Network Mode: Global
APNs: None checked, EHRPD and LTE - Verison Internet are white, the rest are grayed out.
Mobile network type: LTE:14
Service State: In Service
Mobile network state: Disconnected
I appreciate your time.
I got the same issue, was working yesterday but today nothing. If I force it to cdma only I can get 3g data but it didn't stick around very long either...

northeast is having data connectivity issues at the moment- I called in and thats what support told me so most likely its the network right now and not your phone with the issue

Thanks for the quick replies Neo and Chewwy.
Good news, 3G is now up on my device and it appears to be stable for the moment. No 4G yet, but I do have one more question just to make sure I didn't accidentally change something when I was troubleshooting it.
Network mode should be set to Global?
Should a specific APN be selected? Currently, both EHRPD - Verizon Internet, and LTE - Verizon Internet are white and selectable, however none seem to be checked with the little green dot. The rest are still grayed out. Is this normal, or should I select one?
Interesting to hear about the N.E. network issues. I suppose that makes me feel better lol.
Hey guys I did a search and found nothing. Any time I'm connected to Wi-Fi, I can't receive calls or texts. I'm on Sprint. Anyone else have this issue?

Yes, have done tons of research and am having a similar issue. It's believed to be software related. If LTE or Global are set as the "Preferred Network Type" under Mobile Network AND wifi is turned on, then the mobile signal cuts out when it goes to sleep. With 3G set, the phone works fine with wifi turned on. I've tried wiping the phone and also loaded the factory 4.4.2 image via fastboot this morning and still have the problem. Some people have RMA-ed their phones and still report the issue, so it must be a certain combination of settings. It's also being reported from Sprint and T-Mobile user, so it's not restricted to just one network. As for me, I'm on Sprint in NYC, have an AC router and using an Airave. My Galaxy S4 didn't have any problems.
Here are a few threads that I've found:
XDA - Signal Problem
XDA - Signal issues with new baseband solved by flashing older baseband
On Google's forums:
Nexus 5 sometimes doesn't ring when people are calling
Thanks man, I had read the Google thread but hadn't find the XDA ones. I'll try forcing 3g while on Wi-Fi.
No problem! If you're on Sprint, there is also this:
Circuit Switched Fallback Issues on Sprint
I'm in an area that is reported as not having the issue, so it's not that for me. Plus, I'm on 3G with the Airave. I remember having the HTC Mogul on Sprint and for a while it would just die if the signal was roaming. An update fixed it, but it wasn't fun. At least in this case the phone still works, not as advertised, but it works. Here's to hoping that it's fixed soon!
I'm the Tmobile user in the Google discussion. It's an annoying problem and hope it's fixed with 4.4.3. However the issue just happened to me in the last week before I got the 4.4.2 update. So I'm not sure what could have happened from a month ago when I got the phone until a week ago. Haven't installed any new apps since then.
This does seem to be working now that I am forcing 3g
Weird, right?
4.4.1 and 4.4.2 both have the same baseband and kernel. That's about the timeframe when the updates both came out, so I assume that maybe 4.4.1 is when the majority of users started seeing issues pop up?
From what I've read, this phone handles cell signals much differently because of the newer LTE TDD. It could be any number of things really, but I don't have the expertise to examine the code to see what was changed between the 4.4 and 4.4.1/4.4.2 baseband. I do believe that all of the Wifi and cell signal issue posts that are popping up now are related though.
I'm also noticing my wifi speeds bouncing all over the place (from ~180Mbps -- ~500Mbps) and I'm only a few feet away from my router. I have a Netgear r6300v2 AC router.
12/14/13 Update: I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue, starting on 12/19/13.
The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and it's causing this conflict. That's why everything seems to work fine when 3G is set as a preferred network.

thanks man!
do we have any update on the situation?
Yeah I wish there was an update soon because this problem is starting to become very annoying. Twice this week I had to check my Google Voice because my Text didn't go through on my phone
Anyone have a fix for this yet?
Does anyone know if any custom roms fix this?
I've read Google is aware of the issue and speculation says they will fix it with the 4.4.3 release.
questions:
(the 1st is stupid, but i'll ask anyways) - when this issue occurs, is the phone set to **wifi only** with 3g / lte in airplane mode?
or does it occur when just setting up wifi in ADDITION to 3g / lte?
&, when you typed Receiving no calls out texts while on WiFi , is your application for texting, hangouts?
if it's hangouts, then google neutered it to only allow text thru the cellular network,
but if you're simply joining a wifi hotspot at work or home, with your cellular network enabled, it SHOULD go thru, ive never had an issue like that with wifi toggled.. even with 4.4.1

just a note -
if you look at slide 7 on the qualcomm snapdragon 800's chipset (you all already know this)
http://www.slideshare.net/jjwu6266/qualcomm-snapdragon-800-mobile-device
there's only ONE chip to handle wifi, 4g, 3g, bt, etc..
with lesser BoM (bill of materials) just maybe, top level s/w userspace toggles, handle more than what meets the eye, the point i was making in another thread..
which not only effects our nexus 5s, but even other phones in various ways depending on the implementation of sw/hd, of the same chipset family..
& sprint has mentioned for the forseeable future, of providing phones, with these types of chips from qualcomm..
~go figure~

the ONLY reason i pointed to the network settings *home vs automatic* in this situation, is because,
the qualcomm sd 800 is an asymmetric multiprocessor, (as will future chipsets be) & you're losing other core networking functions, while gaining another, when you SHOULD have available ALL facilities -
**ASMP vs SMP**

It actually occurs when the phone is connected to LTE and WiFi together. If my settings were to connect to 3G along with WiFi, SMS works fine.
I have to manually change my Mobile Network settings when I get to home or work, where I will be connecting to WiFi (note cellular service is always ,on, I didn't mean to make it sound as if I am trying to send SMS over WiFi). So when home I turn on WiFi along with 3G connectivity and when I leave I turn off Wifi and switch to LTE.
This issue has been happened while unrooted and running stock ROM and it still happens while rooted running Cataclysm.
Also note, the SMS we miss never will come through, it's not as if later on the message comes through...It's gone forever. It also prevents calls from coming through, it's not just limited to SMS.

What worked for me was forcing 2G instead of 3G, hope it helps!
I have recently switched from Straight Talk to an AT&T 10 GB Mobile Share Plan. Since then my mobile data will randomly be turned off when i'm connected to wifi. It wont turn back on when i disconnect, nor when my device receives (or attempts to receive) an MMS message. Is there some setting i may have accidentally accessed since the activation? I don't have any programs that are capable of changing my device status like that (nor is my phone rooted).
Dont get me wrong, i'm glad something is trying to help me conserve battery haha, but it does get annoying since i only notice it when i get a notification that my device is unable to send/receive a picture message, or that i have no data once i leave the wifi network.
Its just weird since it has only started happening since switching to AT&T Postpaid.

Which ROM are you running? That is strange. It could be something with the APN as well. Are you on LTE or stuck on 3g? Maybe your phone is stuck in one and tries to switch from LTE to H or vice versa? I know when my phone chooses H instead of LTE (I use Cricket, but same towers) it takes quite a few seconds to get a data connection to load, but LTE is pretty quick to load.
It doesn't actually save battery to have data off when using WiFi since that is already happening behind the scenes. Not sure why yours is toggling the setting on its own but perhaps a factory reset would fix it.

Everything is stock. I had a APN automatically assigned from AT&T that caused me to constantly switch from HSPA+ to LTE. I found a better one online and now get LTE most of the time. I never really gets "stuck".Its not that the data isn't loading, its that it is literally set to "mobile data off" on my device, and i have to manually turn it back on in the settings. I wasn't aware an APN setting could change other settings on a phone?

it could be an app doing it, and you not knowing that it can.
[Not Fixed] see bottom of this post.
It is fairly easy to install a new D6603 to work completly on the AT&T network. It is not so easy to find the answer of how to do it in the threads and posts. I tried many suggestions and wasted a lot of time. Hopefully this will save you from that fate.
First you must know that you can't use the IMEI number of your new phone if you want it to work completly as it should. If you use the Z3 IMEI you will have trouble with data of various sorts and the phone will go off line when on LTE after 20 or 30 minutes and you will not receive calls or SMS messages. I do not know why but it has been suggested that the AT&T network does not recognise this phone so it causes trouble.
If you have an AT&T nano-sim from your old phone then just put it in the phone. (Cut downs work but can cause other problems some say.) When the SIM is inserted for the first time into a new phone there is a prompt that asks if you want to download the APN. Hit 'yes' and the phone downloads the APN itself.
If it does not ask then go to Settings>More>Mobile Networks>Prefered Network Type and be sure LTE (Preferred) is selected. Then connect your phone to the internet and then go to Settings>More>Internet Settings and select AT&T. You should be good to go.
If you need to get a nano-sim then go to the AT&T store or call and they will give you one or send you one for free. You will need to use the IMEI number from a LTE phone that is already on the AT&T system. You can use your old phone or borrow the number from someone. If the rep installs the sim in the Z3 with the 6603 IMEI don't worry. Just call support later and tell them you sent your new phone back and want to go back to your old IMEI or have a new IMEI (from an existing AT&T phone). They will enter it and off you go. The phone from the IMEI will show in the picture on your account page. Big deal!
Update: This worked for hours last night but this morning it is back to not receiving calls. Simply turning wifi off and it began to receive calls as GPRS was switched back on. My wifi was on which has been said to cause problems. I will test with wifi off and report back. Had "no service" instead of AT&T on upper left of lock screen. A full shut down for several minutes than re-boot solved that.
YMMV. I've been on ATT with a Z3 purchased from Sony store for several months and it was registered in an ATT store by scanning the IMEI off the box followed by updating Internet settings in Setup. ATT online shows unknown model but everything works including LTE and MMS. There is something else involved when problems like this occur probably some setting not getting reset. I registered the Z3 on a new line with a new Sim card because I wanted to take my time moving stuff off my old phone--this may have avoided the problems.

AT&T's system sometimes takes a while to get updated with new IMEIs that trigger LTE provisioning for a users' account.
Once your account is provisioned for LTE you never have to worry about it again, but sometimes if you have a phone the system doesn't recognize, it is a pain to get AT&T to properly provision your account. Supposedly properly trained in-store reps can do it - the key being "properly trained" - Never try to do anything "unusual" by calling AT&T customer service, and NEVER use a franchise/kiosk in-person for service - make sure you're at a corporate-owned store! Even then, some stores might have incompetent staff. I've been lucky that all of my local corporate stores are pretty well staffed.
So you are saying that your Z3's with wifi and LTE on with AT&T are working as they should?
With LTE off my phone responds normally with wifi on. With LTE and wifi on it will not respond to calls after a 30 minute sleep. It does not show missed calls. Calls go straight to voice mail after 2 rings. Could you tell me what level your LTE dBm's are? Thanks!
I was told not to give them my imie# but, after recvng the minisim I had to call them in order to 'provision' it to work at all and they needed that #. I have never had any problems personally and am assuming this may be because you gave them the wrong #. Again I am only guessing. Oth, if I had had a different imie to give, I would have done so myself.
It is very strange and I am feeling it is more signal strength related than how you provision your phone. (Once it is provisioned correctly.) It seems that more people have less problems when they already have a nano-sim and just plunk it in the new phone. This might indicate that they already had a strong signal from the get go. My old HTC One + get's a better signal than the Sony in the same locations with the same (new) SIM. With the Devilcase bumper on it gets 5% less. My very limited tests yesterday seemed to indicate that it was signal strength related. I am not enough of a conspiracy theorist to imagine that AT&T would program their system to not function correctly with sims that are provisioned with these Sony phones which they are obviously ignoring for some reason. Or am I?
I had all kinds of problems with the Z3 on AT&T. The IMEI caused an issue since AT&T linked it to a flip phone and therefore couldn't provision LTE. I changed it to an old AT&T LTE device and then I was able to get LTE but was having the same issue with calls going directly to voicemail and texts showing up hours later in bunches. I found the solution was to switch off LTE in the quick settings menu. All calls and texts came through and on time while LTE was off. If I needed a data boost to stream, I turned it back on until I was finished streaming. This was while on KitKat. After upgrading to Lollipop, I was able to keep LTE turned on and calls and texts still arrived on time.
I use data rarely. Mostly wifi. If I don't leave LTE on, my phone reverts to wcdma preferred. And why can't LTE just work without me having to constantly turn it back on? What bugs me is having the APN settings greyed out. I want to be able to turn it off. If anything it seems the phone itself is preventing me from accessing the sim. It feels like I'm borrowing something which contains lots of MY private data. I know my phonebook is stored locally but I also noticed there is no option of specifying the sim or not. Anybody know how to switch APN on and off? In fact, overall even rooted, I still feel like I have almost no power over it. I can't even disable the cellular connection without going full on airplane mode and I do not trust that. I don't even fly so that needs work for sure. Dumb question but could I buy a working nanosim from say 7-eleven that my apn switch will work with?
"Anybody know how to switch APN on and off?"
On my Z3 on OTA stock Lollypop I have an icon in quick settings to turn LTE on and off. Drag two fingers down from the top of the screen. If no LTE icon then select the pencil icon at the top and select the LTE icon. There is also a mobile data icon switch there.
To turn off your radio completly you can get the Advanced Signal Status app and select additional info at the bottom and click phone information and turn off radio. Probably a number of ways to do it but that is one.
Sim contact storage was a way to move information from phone to phone. You can still do it but not really necessary with cloud backup and storage. Google does it for me without me having to do anything which I like. I still save contacts to the sim just because I can. Export and import in your contacts app menu.

Works fine here. I don't pay attention to the dBm estimates since these aren't measured with calibrated test equipment and vary widely. Those numbers are basically worthless.
The only valid comparison is data performance in a given environment (ideally a difficult weak-signal one) - and at my desk with very weak signal, every phone I've ever used performs similarly to the Z3.
"Those numbers are basically worthless."
True, but we have narrowed this down to the possibility that it might be signal related so it is worth a shot. If people whose phones are working fine would measure the LTE dBm on Advanced Signal Status at the location where their phone sits and works well the most we might possibly see some measure of difference in the phones that are not working. Most of the non-working phones seem to work sometimes so signal strength is the next best parameter to rule out. Thanks!
Here are the screen shots of my phone with LTE on, LTE and wi-fi and LTE off and wi-fi.
How do the working phones compare? Does your CDMA (voice) also go to 0% when LTE is on and GSM = n/a?
Thanks. I think adv sig nfo actually works. I'm amazed actually. I can't find the phone's native greyed out apn switch anyways which really makes no sense.
