When I call someone or if I receive a call it makes no difference. After 5 seconds, call brakes, I can't hear anything for one second, and after that everything is back to normal. EVERY time same thing. I tried stock rom, stock rom not from my provider, slim bean, MIUI...same thing Factory, no help, remove sim, reset, remove battery..no help. Tried my sim card in different phone, works fine.
I don't know what to do except to return it for repair. Any help is welcome.
Thank you!

Here is the picture what shows on the screen after one second silence

In Germany there was a problem with one provider (T-Mobile) who activated HD-Voice on their network which led to the quirkiness you described where the call would stop for a bit after the first few seconds.

This could explain the problem. I am on t-mobiles sister network but in croatia.
Is there anything I can do?
I definitely found that the problem is in fact HD voice. On GSM network mode everything is fine because WB-AMR is set to off in GSM mode. Now the only thing I need is to disable WB-AMR on UMTS and everything will be fine. Or the tech support will do its job and fix the problem. I can finally go to sleep.
No luck. I disabled it but no change. on GSM everything is fine, on UMTS...
EDIT
Network problem.

ok i got a i717 note and a att striaght talk sim card. I finially got the APN setting that came with the straight talk sim to save. Phone is making calls and messaging but the data services are not working. What am i doing wrong?
If your settings are like the ones in the screenshots I posted, then I would say there is likely problems with data im your area.
my settings are the exact same. no luck

also my carrier says "HOME" in the top left corner. I wonder if this has something to do with it?
Mine displays HOME when I pull down the notifications window and only for a few seconds when in the lock screen. Other than that it doesn't display HOME from what I've noticed. I don't think you have to worry about the what is displayed as the carrier's name. Since you are able to make phone calls and received messages (both SMS and MMS?) and the only thing that is not working is just data, then it's probably something in the phone configuration or a problem in your area. If you haven't done so yet I would recommend contacting Straight Talk.
What symbol, if any, do you have to the left of the signal bar?
I know this probably isn't the case but did your turn Wifi off? If not try turning it on or off and making sure it stays off so you can connect to the data network.
I don't know if you have done so but you could try a factory reset, not sure if this would help.
If none of the above works you could try rooting and flashing the AT&T stock rom to the phone or some other rom. (Consult this recommendation with someone more experienced here on the forums. Personally, I don't see more troubleshooting options.)
If there is no problem with the network and none of the above works then I think your phone may be damaged, unless it used to work perfectly with AT&T. Did you switch from AT&T to Straight Talk or did you buy the buy through ebay or on the street to activate ti with them?
EDIT: Just tried a 3 sim card and it worked so I will get another T-Mobile Sim to see if the problem is a didgy sim card...strage as the sim works when I put it in a micro sim to sim adapter in another phone!?
Im in the UK, with T-Mobile and randomly cant send/recieve calls or texts
I called T-Mobile and they refreshed the network settings but I still cant call...they said it wasnt anything to do with network coverage as it was displaying i had signal, but in call settings > additional settings or call forwarding > voice call:
it says "Network or Sim error"
my sim works in another phone too so its not a dodgy sim...so it is 100% down to the phone that I cannot call or recieve calls or texts so not just call settings being messed up, problem surfaced 2 hours after flashing Foxhound 0.3 (but in those 2 hour calls/texts were working)
I have done hard reset, and facory reset, restored a backup...also flashed stock XXLF2, and also LF8 but all with no luck
My IMEI number is displayed in about phone, it is displaying full signal, and T-Mobile in the dropdown menu and im able to use my mobile data from T-Mobile so what is wrong, and how can I fix this?
Would be forever grateful to whoever can help me out...even if your not sure any ideas are welcome as my £500 phone is as good as bricked to me!
I will take it into T-Mobile to see if they will replace the handset under warranty but how do I go about making it seem it hasnt been rooted or flashed custom ROM, I know I need Triangle away but what order etc?
Thanks allot
Remove root apps .
Run Triangle Away
Flash original stock rom .
Check rom counter .
jje
just burnt this rom, everything works but I can't make phone calls, tried to swich to another sim and it works.
Gonna contact my cellular company, does anyone have any idea how do I recognize the problem?
Data works,incoming calls works... it's weird for me and hard to explain, the main problem is they don't support custom roms and I don't wanna fall into this...
thank you!
forgot to mension
I can send SMS and receive, did factory reset, wipe cache...
found my network on the settings and chose it but no outgoing calls, tried another apps for dialing ...
the other sim is on a different same network but with the same frequencies (UMTS 850,2100) and works!
another thing that I thought, maybe it's not the issue but the SIM that doesn't work is not personal but my work cellular SIM, it worked on the same machine with the previous version , which was 4.2.2 custom but not this one, and I like this one because it's faster.
thank you
Hey Guys,
Desperate lurker here saying First of all thanks for all the guides and everything that the devs and everyone that the community has done. I've search all of google and xda but i can't seem to figure out what's wrong with me Xperia Z2 .D6503
. T mobile carrier.
Basically since yesterday, I noticed that my phone couldn't receive or make any phone calls. but data internet, wifi internet and text messaging was working fine. Whenever people call me, i would just get a voicemail notice. At the time I was on the Marshmallow Existence rom. Ive done a lot of troubleshooting since then and still I can only make a call on GSM Mode.
Here's what i've done.
Wiped data and "reset" my phone on the Existence ROM - didn't work.
Wiped everything and flash Resurrection ROM - didn't work still.
Used someone else's sim card , couldn't receive calls either.
Use my sim card on a different phone - that one worked (SO IT'S NOT THE SIM CARD'S FAULT)
Placed back my sim card in the Z2 and reset flashed the stock rom from this page https://forum.xda-developers.com/xperia-z2/general/stock-t3355768
but that didn't work either.
I've also manually put the Tmobile APN.
Basically calls only work when changing it into GSM mode. but when i put LTE/WCDMA/GSM. Calls made under LTE/WCDMA/GSM Won't even make a dialtone when I make a cal. It basically just ends after a few seconds
I'm starting to think it might be a hardware issue because no matter which ROM i put, no matter how many factory resets and data wipes i've done. I can only make calls on GSM Mode.
Does anyone have any other ideas or should I just cry and buy a new phone.?
I suggest you to flash your phone with flashtool v0.9.18.6 and flash 291 ftf and wipe all
@whatsadophone
Have you try resetting APN for your SIM card when on your device?
thanks to everyone who tried to help. I don't know what happened. but after i tried putting the sim back in the Z2 to check my signals using Signal Spy, It suddenly can use LTE again. Only problem is since i installed that stock ROM, I lost my recovery mode and can't get it back. But i wont push my luck and just keep it like it is till i buy a new phone.

i have same problem any help pls?
try doing that signal spy solution by luck that I did in the post before that
Hi everyone,
I'm having an issue with my device since yesterday. I wanted to make calls but as soon as I try to call someone I was getting "couldn't connect message"
I thought that it's maybe something to do with the carrier but i restarted my device, and after the restart I saw that I now only have 4g, and not 4g+ displayed, and still got the couldn't connect message then trying to call anyone. When switching to 3g/2g in settings I was able to call, and I was also able to receive calls even when on 4g.
My internet is working fine over mobile data, there were no issues with it.
Also, VoLte icon is being displayed all the time, thatdidn't go away.
At some point yesterday I was able to make calls over 4g again, but never regained the 4g+ and a few calls dropped after 5-6 minutes of talking.
I tried a SIM card from a different provider, but still see just 4g, and not 4g+
So I am not sure what could be the issue anymore.. Did anyone maybe encounter something similar after this last update? Maybe that's the issue. I don't know if I should consider suspecting a hardware issue because internet works fine all the time.
Clear system cache, clear sim toolkit data, and do a network reset.
See if that gets it...

Thanks for the tip!
I actually tried doing all of that and nothing was helping.
At the end I changed the CSC back to my stock one (TOP) and 4g+ is back.
I have no idea why this happened because I was using BTE csc for months and everything was ok. I'm just glad that it's not a hardware issue.
