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!
I noticed if I go to the mobile networking settings and have it it on lte/3g if I leave a 4g area, 3g works ok. If I put the toggle specifically on 3g it shows I have 3g, but anytime I tried to search google or access a data connection the signal goes away and gives me the signal with an exclamation point. I tried finding info on this, but didn't see anything when I searched. Anyone else have this issue? I am on Sprint with the 64gb white device. Thanks
I leave mine on 3g due to the lame multiple text issue. It has no problem staying on 3g. Perhaps try updating your PRL/profile and see if that helps.
I don't have 3g either if I set it to 3g only. I don't leave lte service too often to test whether 3g works when it switches on its own. I may have to make a trip to the mountains to test it. I do know that my old Note 2 would loose lte after flashing tons over and over and I would have to flash back to 100% stock the factory reset from the settings app to fix it. I may try this with my Nexus, about time for a wipe anyway.
Factory reset does not fix it. Just noticed that I don't even get 3g when it is set on LTE. I'm gonna go talk to my cellular provider about it.
I don't know why it wouldn't work. You did update profile and PRL also right? Here's some shots of mine and it's working fine.
I have a bad Sim.....I also don't have a phone number as well..... I swiped with an old card I had and my number appeared, I guess I'll be visiting the store tomorrow to get a new one. Maybe it'll fix my 3g. Its also not wanting to let me pick 3g as an option now, just stays on LTE.
KB112 - Are you on sprint also? I updated prl/profile and no luck still. 3g still works if I am on lte and go into a 3g zone, but if I toggle it to 3g only I get no data. Wondering if its a sprint thing or a lollipop bug on Sprint, or a bad sim, missing feature activation.
Bluemgt06 - did a new sim fix it for you?
Sorry, didn't see this earlier. But yes, I am on Sprint. My 3G would work fine if I set to 3G only. Not sure why yours has issues with this?
Oddly I tried it today and it started working. I think it could have been some kind of issue with the tower/upgrades or a bug that a reset may fix on occasion perhaps.
Hi guys,
My toy is a samsung note N 9600 and its factory unlocked. Last week ported out from T-mobile to keep my original number and facing a wried issue.
The day I ported out from T-mobile, VZW network couldnt be recognized when I tried to activate the VZW sim card. "No network connection." and no call or text can be made. However, after I RESET my device to factory model, it SUCCESSFULLY recognized VZW and LTE function works well. Sounds wried? The story doesnt end here.
Yesterday after I turned off the VZW sim card by accident-- n9600 is a dual sim card which allows you to turn either sim card off-- the network connection lost again, im not talking about LTE connection, but all network service including internet, phone call and text function. Tried a lot to get the connection back but failed. Guess what? RESET, THEN VZW comes back!!! Being driven by curiosity, I turned off the sim card agian, and then, as my expect, no network connection. Ok, rest---works---turning off sim card---no connection---reset……
I am really annoyed by this and have no idea why it is. So if anyone of you have clue of it, plz let me know. Thank you in advance!
Teddy
No one experienced same issue before?
has anyone noticed that the 4G on the S10 is quite buggy?
the speeds are extremely unstable, and sometimes completely unusable. (not a problem with the carrier, tried it on another phone and it's fine)
What I've noticed is that if it ever goes into medium power saving, 4G will stop working completely, it'll still show 4G, and i can still make calls, but no internet connection, even after exiting power saving mode. The only fix is I'd have to restart the phone for 4G to work again.
anyone have the same problem/ knows a fix?
I've read that I should do a factory reset, but I really want to avoid that, setting up the phone is time consuming.
Side note: battery life is not as good as expected, but that seems to be an issue for all exynos, not just me.
Same Problem here i unlock phone 4G shows but it tanke some time if i can use the Internet
Speed is Very slow and unstable
I am having connectivity problems as well. Keeps loosing the connection. I have to turn on airplane mode then turn it off all the time.
I don't have any problems with network connectivity, so far. In the link my result a moment ago: https://www.speedtest.net/my-result/a/4796337263
Hope you get some sensible connectivity soon. Cheers!
Same issue here! It was fine since I first received the device, but yesterday, I manually changed the network toggle to get better indoor signal. However, even after setting the toggle back to the original setting the LTE and data service kept dropping out. I tried manually toggling, switching network bands, etc... but nothing worked. It just keeps dropping data service.
I just hard reset the phone moments ago, and will update accordingly!
Update - Even after a network reset and hard reset it still dropped to Edge data a few times. However, after the last hour or so, it has locked back on to LTE+ and is holding strong. Seriously hope this is a software bug and not a bum radio chipset or antenna.

I'm on tmobile and my data is horrible in certain and what's weird I have all bars.

not sure if i should say that its good to know I didn't get a dud.
but man, samsung needs to get their sh*t together, this is not acceptable for a flagship phone.
looks like i'll have to do a factory reset soon.
I'm on tmo as well. I have a feeling it's just jacked up radio software. I did some more tweaking and went into band settings *#BAND# on the dialer and disabled all the LTE bands that aren't used by TMO and that seems to have helped as well. It think this issue is congruent to the known issue with Sprint devices trying to connect to incorrect bands. I haven't used it out and about yet, but it definitely helped my phone stay latched on to LTE from my home. Additionally, when it does drop to HSPA, it doesn't get stuck like it used to.
I recommend tweaking the band setting before doing a hard reset.
Update - still doesn't fix the problem. Pains me to say it, but I'm afraid I have a hardware issue. I'm going to try a sim card swap as a last ditch effort, but will also seek an exchange as well just to get ahead of the problem.

This shortcut only works on Snapdragon version, do you have Snapdragon with 4G issue?
This code only runs on the Qualcomm chipset version. Oddly enough, my friend with the Exynos version has no problems, even though he's missing a couple of TMO bands for the US.
Yeah I have Exynos S10+ as well and it runs fine on T-mobile USA

This code is not working on SM-G9730 Qualcomm Hong Kong version. Any ideas?
Same problem here. I got the snapdragon US unlocked variant using here in Spain and compared with my old Google pixel, they do not have the same speed LTE connectivity even using the same SIM card. I tried to force using the 20 BAND (800 MHz) but I dont really know how. My galaxy s10 plus is using the BAND 3 so it does not let it picking the fastest possible band in my city. Any ideas? I also did think galaxy s10 plus US variant did not have 20 LTE band, but I checked it and realize it even does. One more question, what is the difference between 4G and LTE? Here in Spain all devices are running 4G, not seen any device running LTE, but my new samsung does. How can I switch it to 4g or LTE+? Thank you everyone boys.
just wondering if anyone has gotten the ASCA/ASC8 update and can report whether this problem is solved wit firmware update?
Bands matter depending on where you are. Depending on your area, only specific bands will be used. However, some bands used, while not faulty, are easily interfered for some reason with cases or other obstructions like your hand. Most likely, Samsung is planning to give a large update considering signal direction. I would probably not factory reset if you have a lot of data, and the problem would probably come back.
I ended up having to send my device in to Samsung for analysis and repair. I'll keep everyone updated.
after ASC8 update, i think the problem has been solved, havent noticed any problems so far
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.
