My new xperia z3 compact (D5803) receives text messages and calls very intermittently. I'm on AT&T US, stock firmware.
- If I am using the phone (or have very recently used the phone, say within 30 seconds) then most calls and text messages come through fine (though not always).
- If I leave the phone alone for more than a few minutes, text messages or calls almost never come through - though occasionally I get a text message many hours after it was sent.
- If someone leaves a voicemail (because I didn't answer the phone, because the phone didn't ring!), I don't get a notification until I open the voicemail app and manually sync.
- I can make a phone call or send a text message with no problems (texts arrive immediately).
I don't have any of these problems when I put my SIM back into my HTC One M8.
I've tried the following to fix this:
- I went to the AT&T store and had them give me a new nano SIM. It made no difference; same issues.
- I factory reset my phone. It made no difference; same issues.
- I updated to the US version of the firmware. It made no difference; same issues.
- I put the SIM into a second, until that point unused, xperia z3. It made no difference; same issues.
Given that I have exactly the same issues after changing both the SIM and the phone, I can only think it must be some kind of compatibility issue with using AT&T on this phone - except I see that many other users of this forum are on AT&T and aren't having the same problems.
I do notice that I don't have the best signal in my house (usually 1-2 bars) so I'm wondering if maybe that could be related? As I say though, my HTC One works fine, as do all of the other AT&T phones in my house.
I think my next step will be to go and buy a T-Mobile prepaid SIM, just to see if that works, but does anyone have any thoughts or suggestions? All in all this is getting pretty frustrating, because I LOVE the phone, but right now it's unusable for me.
I would suggest reading this thread below. It should give you some tips on how to resolve your issue.

Thank you for trying to help!
I probably should have added that link as one of the things I had already tried. To be specific, my APN settings are:
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC http: //mmsc.mobile.att.net
MMS proxy proxy.mobile.att.net
MMS port 80
MCC 310
MNC 410
Authentication Type None
APN type default,mms,supl,hipri
APN protocol IPv4
Bearer Unspecified
---------------------------------
I'm beginning to think it *must* be a signal issue, even though all the other phones in my house are fine. I have the "Advanced Signal Status" app installed, but I'm not sure what I should be looking for to see if there's anything fishy
Don't forget to download the Internet and MMS settings for your phone. You go into Settings > Wireless & Networks > More > Internet settings and download settings for Internet and MMS
Thanks again for the suggestions.
Sadly, it's still not working. I'm pretty sure I had already downloaded those settings, but I did it again anyway (seems you can just download over and over). I even reset the phone after that just to be sure, but the problem persists.
I have the same issue and I live in Sweden....
Im having the same issues. I restart the device and then come all the missed calls and missed txt messages.. i really hope theres a easy fix to this soon.
So, I switched my SIM from AT&T to T-Mobile and it fixed my issues. It seems that the either the poor AT&T reception in my house or some other strange incompatibility between the phone and AT&T was the problem.
Either way there's obviously some kind of issue with this phone - my guess is that when connectivity with the network is poor, the phone maybe times-out and gives up. Perhaps Sony will fix this with a firmware update at some point. In the mean time I would suggest that other folks having this issue maybe go to a part of town where they know reception is very good and see if the problems happen there.
So after 2 days of of testing, a new nano sim card and several phone calls to ATT I found temporary fix. Change your Network mode to WCDMA (preffered)/GSM. While this wont give you LTE it will prevent the missed phone calls and txt messages and at least you have HSPA+ . The problem is the LTE connection to ATT. The connection either drops and or prevents phone calls /texts from coming through the lower HSPA + or 2g bands... Not sure why this is. Hoping that when the Sony Store models start shipping on Nov 2nd they have the same issue and Sony will send out an update to fix the connection issue.
I'm on the US ATT network with the same problem as well. After trouble shooting I have come to agree with you. I'm really hoping Sony sends out an update.
Is this a problem on Tmobile USA with Z3 Compact also?
same issues!
I have two Z3 compacts (US version purchased direct from Sony) on my family plan with the same issues of not receiving SMS or calls when connected to wi-fi, and occasionally cannot receive SMS or calls when not connected to wi-fi either. I am always able to send texts and calls, and MMS/LTE always work (I am usually e-mailed when my phone isn't working and I get that right away). Whenever the phones aren't receiving calls, it rings once and goes to voicemail, which tips us off that the phones aren't working.
If you are also getting this problem, please get on AT&T chat and ask them to escalate/forward to their manager. We've got to get their attention. Additionally, I was told that "Okay so since the phone is unlocked our service is not guaranteed to work at full capacity, also I can not submit a case due to it is not an at&t phone. "
Yep - Same problem over here. AT&T in Northeast USA.
AT&T tried everything they could (resettings connection, etc) but again also said that it isn't guaranteed to work because it's an unlocked device.
I'm doing a system repair on the phone from the sony desktop application. Hoping it will fix, but not hopeful. Now sony says they want to have my phone in for testing. :/
I'm hoping they realize soon that this is a bug, and not a case of a broken phone.
Same problem here on cricket (AT&T) in Houston. Just disabled LTE. We'll see if that fixes it like it did for the other guy. Sony needs to get on this.

Not working MMS
Yep I have tried all of the above solutions and nothing is working. Changed APN multiple times, factory reset, switched SIM, called att, went into the store.
Like above, ATT came to the conclusion that unlocked phones are sometimes not compatible with their service and there's only so much trouble shooting they can do.
I have ATT in san francisco, and it's looking like I'm going to return the Xperia z3c. Shame it's a great phone besides the MMS issue.

Confirmed that this worked on my wife's z3c. She wont miss the LTE anyway since she is always near wifi and when she isn't 3G is definitely good enough. We streamed spotify for an hour today on country roads on her phone on 3G. No issues.

sorry to hear you guys are having such issues...
My z3 compact on att works flawlessly. I swapped my nano sim from a iphone 6 i was trying out straight into this.
Att did mention something about some settings they had to flip in the back end when i switched over to a nano sim from the sim i was using in my lg g3. If you guys loose all hope have a buddy with an iphone on att and use his imei and let att configure the sim for that phone then swap the sim into the z3...could work because i know it does for me
Same issues here. I have a new D5803 on Straight Talk (AT&T). I live in the mid Atlantic. It seems I don't receive calls/texts when I have 2 bars or less. Not sure about LTE vs. HSPA. I always have Wifi on so not sure if turning it off would make a difference. THIS IS A HUGE ISSUE! Hopefully a firmware update will save us. Has anyone contacted Sony?

Thanks for the info, but this isn't a viable solution! I shouldn't have to keep Wifi off to ensure I receive my calls/texts!

I'm having major trouble with my phone and need some help.
I've got a standard Vario III no flashed roms etc..
When I'm on standard GPRS network the phone works fine, calls internet etc..
However whenever it switches to a 3G or H network I cant make or receive calls or use the internet. The funny thing is that when it tries to access the internet it looks like it connects but when you click on the 3G (with the arrows) it says there are no sessions active.
Help!!
yes.. i have the same problem too
so we must switch the band using gsm to get phone works normally. if we set AUTO it will failed to make call or to receive call.
another kaiser from my friend was normally in same area. please help us.. thanks
maybe I have the same problem, I can't make calls, when I make a call it do a sound alert and end the communication.
The line is ok, I was using it with other phone without problems. I spend today 5 hours with the mobile service provider (CLARO ARGENTINA) tech service and they finally say this must be a problem with the pda, not with the service (after testing all possible alternatives)
The phone is almost new! I can connect to EDGE and navigate the internet, H or 3G appear "some times" but it get EDGE 99% of the time.
When somebody call me the phone ring and then then lost connection. When people call me they receive a "network error".
1 of 20 times I CAN do a call.
Do you think is the phone? or there is some update ? I'm downloading a 6.1 rom to test with it.
it is not the phone. Assuming your are using T-Mobile, Edge network coverage is almost 100% complete, while T-Mobile's 3G network is in the early stages. So you will usually get Edge until 3G is nearing completion - T-Mobile is slow
Here is an article: http://www.boygeniusreport.com/2008/05/05/t-mobiles-3g-rollout/
Well I use Claro AR (in Argentina). EDGE is 100% and 3G is quite well in my city, but what do you think about my phone calls are closed after 5/6 seconds with error and then it lose phone coverage. Never happened with other phone, same provider, same line, other phone.
Now I have updated to a duttys Rom with a newer radio version (1.65.x, my phone comes with 1.21.x) and still happening. Now I will test another rom
It IS the phone.
If you do a search on this board lots of people are having that problem, as I found when encountering it myself. It's a hardware fault in the radio part, that requires sending the device back to HTC. They actually replace the whole mainboard to cure it, so it's a serious issue.
Awaiting to receive mine back, it's been there for a month now
Here's a large thread about it: http://forum.xda-developers.com/showthread.php?t=335074
thank you
I force the phone to run under GSM network (not WCDMA) and the phone works perfect, internet too (only EDGE). But I can't use 3G because if I set it to WCDMA or AUTO in the phone network section, it's unusable.
That's the one. I'm receiving my Kaiser back from repair tomorrow, can't wait, and hope it will be fine this time... It's been at the service center for 6 weeks now
hello, any news ?
Yep, received it back like 3 weeks ago, everything works flawlessly. They replaced the whole mainboard just like for the other people with the same issue.
Ok I'm dead. Sending the devide to north america from Argentina? now way.
Why? I had to send it to the UK, not much of a problem...
and it back again to you? awesome!! not easy in latin america!
Ok I will call tomorrow the seller to ask the guarantee. let's see what happen.
So I recently got a T-Mobile Samsung Galaxy Note 4. As we know, it's unlocked 100% without any special root methods or entering in codes into the dial pad. With that being said, I popped in an LTE Straight Talk SIM card, transferred my old number to the new SIM and configured the APN and for a long while it was working fine with no issues. Then out of the blue, I had no data. It absolutely quit without warning. I go to check the APN settings I had previously and they were gone. I had redone everything and saved the settings. However, when I go back out a menu, no Straight Talk APN. I did the same thing again....and once again no APN settings. Just the default T-Mobile LTE APN.
So I'm at a loss. It was working fine previously and now I cannot set APN settings. I have reset the phone more than once (reluctantly). Any thoughts? Any help would be appreciated since I'm paying those bastards $45 and some change a month for service I cannot get. Also as a note, I can receive and send text messages with no problem. Calling number results in "you are not registered on a network," but I know the fix for that.

Try setting the APN with this app https://play.google.com/store/apps/details?id=com.tracfone.straighttalk.stdatasettings
Sounds like your phone got black listed. Did you buy it from Tmobile? If you bought it from some one else it was either a stolen phone or the previous own stopped paying for it.

I had bought the phone from a local gas station owner (who had 2 other T-Mobile phones with him). It was working while he showed me the phone (he had gotten several text message and Facebook updates). He then reset it. I bought a Straight Talk SIM kit and went to work. I had working data until the next day. I had played around with some more internal settings, like updating the touch sensitivity and more. Everything was working until I refreshed the Wi-Fi antennae. Don't think that would have anything to do with the 4G/LTE radios or regular antennas. Overall, it was working, so I don't see how it could just magically stop.

If he bought the phone on a lease from T-MOBILE and never fully paid it off T-Mobile would black list it. Or if he sold you a lost\stolen phone.
You can contact T-Mobile or check the IMEI on one of those checker sights to see if it has been blacklisted.
Sent from my SHIELD Tablet using XDA Free mobile app
You can check to see if you're blacklisted by visiting the T-Mobile website and using their IMEI checker. If you're blacklisted you would not be able to place calls. I will attach sample AT&T APN that works for me. I'm on Cricket and not StraightTalk but it may work for you.
For all who helped out on this post, THANK YOU! I figured what my issue was. SIM card is fine and the data settings work as long I don't configure the MCC & MNC settings. Changing the MNC from 260 to 410 is what caused my saved APN to disappear. Not sure why that happens, but if any of you have an idea of why, direct me to the thread that explains this or if you know, quote this reply. And another thing, I am able to send texts and make calls, but due to the location I was in, texts sent at half the speed of smell and making a call was impossible due the phone claiming I was "not on a registered network" even though ST is a network (duh). I have no service issues on my Note 3 N900A when I that. Anyone think it could be because AT&T's device antennas differ from that of a T-Mobile Note 4? Personally, I don't think they would since they are both GSM and operate on the same bands (I would think), even though the Note 4 has "newer" technology. Not really worried about data, texts or calls since I have Wi-Fi in said location.
Again, thanks to those that helped me out. And, again, if anyone has any ideas to the information said above, by all means give your say or direct me to where there is substantial info.
Hello, I recently purchased a gpe nexus 6 for my cell carrier Thumb cellular. Small company that uses verizon towers in rural America (LRA) one of the bigger LRA carriers is bluegrass cellular if it would help any. Basically these LRA carriers partner with verizon to give coverage in rural areas otherwise skipped over. The phones themselves are almost exact clones over their verizon counterparts for what that may matter.
My issue is I have a bug where I can not send out sms messages on lte but when preferred network is set to CDMA only Prl it works. Set back to lte CDMA and they fail to send again. Everything else including receiving sms works. Any idea on what I can do because I don't want to send this device back. Seen its common on CDMA carriers but no real fix has been found besides to stay off lte. Any help would be great, Thank you
Sounds to me like it might be something with the APN's. Maybe you could look at another (android) phone that works properly, and see the apn's, and then manually enter them in the nexus?

I have a galaxy s5 on the same network and saved the apns and restored on the nexus using apn backup restore, I get lte and can send mms. The issue is sending regular sms while on lte. If I force 3g or even 1x I have no issues sending a text. Seen its common issue with this phone on a CDMA network but no idea what to do to fix, updated to stock 5.1 as soon as I received the phone, tried chroma as well as bliss pop and all have the same issues. Really don't want to return the phone but doesn't seem like there is a fix

Why did you do apn backup/restore rather than letting the n6 pull apn info from your sim? That may be why you're experiencing issues?
Although, standard sms doesn't have any specific apn settings afaik, and should just work as long as standard voice works...
Btw, what build are you running?

Did that before I restored apns actually. Had an issue so that's when I used my thumb cellular apns which are different then the verizon ones it gives me thinking it would help me for some odd reason even though apns have nothing to do with sms.
If I go to dialer and dial *#*#4636#*#* I have LTE/GSM/CDMA AUTO (PRL) everything works except sending an sms. Only thing that won't work. If I change it to CDMA only I will get either 1x or 3g but my phone works how it should. Should have absolutely nothing to do with apn settings. Seen this issue is common on verizon but more so on sprint but not everyone is plagued with this problem, but exchanges and new sim cards don't fix the issue for those whom experience it.
I'll post a log cat, I don't know what to look for so if someone could it would be great. I'm testing with 8sms
https://www.dropbox.com/s/xwj5q7wut05ybhl/Log_2015-05-30_22-12-22.txt?dl=0
I'm looking for answers too I have a similar carrier (another partnered with Verizon in the lra agreement) and interested in buying a n6 provided this issue can be resolved. Being a carrier that functions the same way I'm 99% sure I'd also have this same problem.
What doesn't make sense is that when network mode is set to LTE/CDMA AUTO prl, you cannot send sms but you can receive them, send/receive mms, make and receive phone calls etc. But if you do cdma only and limit it to 3g, it all works.
Does anyone have any suggestions in things to try?

I tried that before and had no luck. Going to try different modems tomorrow and a couple BP edits. Running out of ideas to try sadly. Only idea I have is how the phone is communicating with the network, same issue I saw on the nexus back in November with the sprint network. Seems like a radio update fixed the problem.
AT&T in Chicago. We have issues with signal on the Z3C in our apartment. Trying to troubleshoot, but not really sure how to go about this.
The symptoms are phone calls that never ring, and text messages that don't get delivered on time. Then all of sudden the voicemails and texts come through in a bunch. Oddly though, can always make a call or send a text. This is on WiFi if that matters.
Have a Nexus 5 and a Nexus 6p in the house, with no such issues on either of those.
I tried some network strength tools from the play store, but the dB reading on the Z3C is just coming up blank even though I'm currently able to send/receive texts, so something is wonky there.
Any one have some advice? I was thinking of changing the preferred mobile network from LTE to WCDMA, but then do I lose access to LTE all the time? Thanks in advance.
this has started happening to me too on my z3c. I noticed it this week. Same symptoms, but the occur everywhere;
Info
Sony Xperia Z3 Compact D5803
Rooted & Xposed Framework w/xPrivacy debloated Sony ROM Android 5.1.1
AT&T Service with tethering and mobile group family plan
Houston, TX USA
Symptoms:
-Occasionally phone calls forwarded from GoogleVoice to my ATT phone number (over standard voice, this phone doesn't have VoLTE anyway) don't ring, or show up as a missed call. The only way to know a call came through is the voicemail notification in hangouts, if they left a voicemail.
-While driving, cell signal drops to 1 bar or less, then jumps to 5 full bars instantly, while connection to the internet is intermittent. (this was not an issue last week to my knowledge, it use to move from tower to tower quite well)
Troubleshooting Attempts:
-Added my own APN settings rather than using the one the phone downloads automatically. I used the settings from ATT's website, and when compared to the downloaded one, the only thing missing was "hipri" in the APN Type field. I just did this, so the result is yet to be determined.
-Restarted phone
-Cleared Caches
-Checked all other obvious settings
-Called ATT and updated my registered IMEI when I bought the phone two weeks ago from someone on craigslist, so can't be that. (I've also moved my sim into my old Moto X to test, and that doesn't seem to have this issue.
Hope this helps

Does not fill me with hope. We just flipped the LTE off, I'll post the results back after Christmas.
Sorry to say we already have hirpi in the APN, but hopefully it works for you.

So on Monday ATT decided to deactivate my sim card because they believe my phone is incompatible with their network now. All my bars went to 0 with an x on it and I couldn't do anything on the phone. I went to an ATT store, got them to give me a new activated sim and I put it in my phone and all my bars came back.
My phone says VoLTE again too by the signal bar area. I also tested a text and it went through fine. I received a phone call and while it works fine, it sounds like junk now. Like it is no longer actually using VoLTE like it always has. My phone doesnt seem to have any data however, when it should have LTE just fine. I also cannot make any calls, even though it says VoLTE on the phone, it just re-routes to ATT customer service instead of going through with the call.
When I go into the network area in settings it says no IP address either. I looked and my APN is set to nxtgenphone, Preferred Network Type selected on LTE. Before ATT deactivated my sim card LTE has always worked fine, and LTE should still work fine. It is only the 3G network being shut down. Also given the fact I have the VoLTE icon the phone is apparently connecting somewhat to an LTE network.
So does anyone know how to fix settings to get data working again? Is it just an APN that needs to change? What is everyone else doing with the network shutdown and has anyone else had issues like this?
I had the exact same issue, your issue is in fact APN settings I'm having them as well. Try deleting your current APN and putting in a new one. Once I got a new sim my APN reset I could call but no data and no text. I have half of the APN information in place and have data and basic text, but once I input the MMS port the APN data disappears still trying to figure that out. Not sure if anything I typed is helpful but at least you know your not alone with a mi11 on ATT and it can work

Thanks for the reply. I tried deleting the MMS port and also the proxy just now and data didnt come back. I will try searching around for more APN info for how phones are supposed to connect now and see if I can find anything.
It looks like from what I could find that it is due to an IMEI whitelist ATT has, blocking data connection on any device not in their whitelist. The solution seems to be to root the phone and change your IMEI to a whitelisted model.
While my phone is rooted my IMEI is not cloned I definitely would not share my IMEI with ATT. When I got my sim card yesterday I had the attendant activate but I did not provide my phone so he did not get the IMEI from my phone. If you got a sim and they input your IMEI that could be a problem possibly. Just a suggestion to try and get a sim activated at a store without your phone.
I had also heard that most ATT MVNOs were not having the device whitelist forced on them yet, so I went and tried 2 different ones yesterday. Both failed to get the phone working on their network with their sims.
Before I went through the hassle of rooting (and most likely losing payments) I tried ATT again anyway. I used their online customer service chat and the first person I chatted with said he could help me with the lte data problem and the IMEI issue. I was skeptical, but he actually did fix it all up. He just needed my sim ICCID and my phones IMEI1 and he submitted the info to their backend people for adding to their system. It took almost an hour and a half for it to get added, but overall it was a pretty painless process and I was browing the web most of the time while waiting in chat. I now have LTE data again, VoLTE again, and "5G" too (which ATT 5G is really just one or two more features than normal LTE and is no faster in speed and uses LTE data bands). I attached a screenshot showing the data and VoLTE working on my phone. The first signal is ATT, the second is TMobile (which has always worked and never had an issue, their 3G network shutdown is going on for another 4-5 months)

Happy you are back up and running and I'm glad that you found someone at ATT to do the fairly easy work of getting your IMEI cleared. Lots of people have been worried about devices not working on ATT because of this whitelist issue glad to see there are workarounds just wish ATT didn't make it so convoluted.
