Since I updated to 4.4.2 on my HTC ONe GPe, I've been having issues sending or receiving texts over LTE. Receiving calls as well. I can make the call (since it switches from LTE to HSPA). It specifically happens on the LTE network, not on HSPA, or 3G, or 2G.
I honestly don't know if it's a software issue, or it's just a coincidence the network is having issues for a few days and counting. Local T-Mobile said it's going to check on the issue, we'll see.
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?

Yes it does make a difference. Turn it off and everything should work.

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!
For some reason I can't make calls. I'm using the stock dialer on a stock rooted ROM (see sig).
I dial a number and it looks like it's working (the call timer starts counting and what not) but it never actually calls. Just silence.
I haven't been able to test receiving calls yet but I did at least get some missed calls earlier when I was away from my phone (it was when I tried to return those calls that I discovered this problem).
I'm on Verizon. I have LTE set as my "Preferred Network Type" in Cellular Settings. Data works fine in both LTE and 3G areas. Texts work fine. Just calling seems broken.
Had anyone seen or heard of this? I searched this forum but didn't find anything.
poor connectivity on WIFI network on nexus 6
I also face the problem if not able to make/receive calls when WIFI network is activated.

Are you on the 98r radio? That's the one that ships with the Verizon branded Nexus devices and is different from the radios in the other 5.1 builds.

what if you turn on your speaker?
nevermind, the ops post is from jan 14th, and someone brought up this thread again. people, this post is before the 5.1 update came out. let this thread die.
I just bought my note 5. Its the dual sim version. So the first few days was days.... i started having difficulty with making outgoing calls... texts are fine... its like 1 out 10 calls would push through. So i rebooted my phone thinking that it might resolve the issue....unfortunately it did not. Then a few friends sent me a message that theyve been trying to call me and it always says im out of coverage are... the whole time this was happening I was connected to LTE. When i changed my mobile network setting to 3g/2g .... then calls came in and went out. Has anyone have the same issue with note 5?
The international versions don't have VoLTE enabled. Not sure how to enable it. Mine also doesn't have WB-AMR (HD Voice) enabled either.
Thus, calls need to be switched through the HSPA network and can't be routed while connected to LTE. Essentially when making a call your phone switches and tries to register on HSPA, quickly.
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.
