So I was attempting to get VoLTE to work on an M Rom. I flashed 6.11.3 but even though VoLTE was enabled, calls kept dropping to 3G. After a few hours of frustration and flashing different roms on the forum to try to get VOLTE working, I conceded and flashed my original M Rom. However I couldn't get it to connect to my mobile network. I then realized that my IMEI and who knows what else was corrupted / showing 0. I managed to flash the IMEI using a guide on this forum and I can now get it to connect to the network at least for data. However when I try to make a phone call, I don't hear any ringing. And when someone tries to call me, their phone rings and eventually goes to voicemail. However nothing happens on my phone / no call is shown. Any help would be much appreciated.

Hi all,
Looking for a bit of help/advice.
On occasions, probably between 1-3 times a day, when I try to make a call on the Hero, the call appears to look like it is dialing out but it just sits there saying 'dialing' but never connects to the destination which can be any UK number / Orange 150 etc. Either rebooting the phone or leaving it for 10 mins or so fixes the problem, but it does become annoying!
At the same time as this happening, when I try to send an SMS, I get the error 'SMS not able to send' in the notification bar. Again, I have to keep trying and it sorts itself out.
A final problem and I am not sure if it is related or not is I have had numerous people try calling me at various times, my phone doesn't ring or display a missed call, nor do I get a missed call SMS but the person who tried calling me said the line was actually ringing first and then went through to voicemail. I have witnessed this myself by calling my phone, getting a ringing line but the phone doesn't respond?
Any ideas of help would be appreciated. This problem has existed on Modaco Roms 2.2, 2.8 and 3.0 - I'm on Orange UK.
Thanks,
Nick
I have the same problem with the Orange Poland. When I logged on to the 3G sometimes you can not call or send SMS. When I switch to the 2G network problem disappears.
Yeah, it is strange, I have done that too, turn off the 3G to 2G and back to 3G which sometimes cures it, but not all the time.
I've tried various things, made sure the apps aren't closed with Taskkiller or anything like that. There is no specific time or occasion it happens, it just does now and again.
Well I have tried everything. I recieved all the settings from my operator , changed over 10 ROMs and gone back to the original too, i tried what you said to turn 3G off , i reset to factory , i unrooted.....Nothing works for me. I just get "Unable to send". I also tried 4 SIMs from different operators !!!
Hi. M facing this problem for about a week. My 3g is connected and I can access net and download but the problem is that I am not able to make the second call or receive calls. I am able to make a call and then not able to make any call. I have to switch to airplane mode and come back again to make the next call or receive calls. I have tried flashing stock 4.2 and flashed several other custom ROMs. But still the same. Did any of you have the same problem and rectified it???

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
As the title says, as soon as I start a call it ends and when someone tries to call me, they get the voicemail saying that I'm not reachable and I get an SMS saying that someone has tried to call me while I wasn't reachable, but I don't get any call popup on my screen.
Tried flashing every modem firmware, wiping cache, switching from google phone to stock, turning off volte but none of those worked.
Please help me, I've been struggling with this problem for three days and it is impossible to work like this.

Check your APN settings and if necessary correct them to what your carrier says they should be. I had a similar problem and that was the fix.
If that's not it, try your SIM in a different phone if you can. You might have a bad SIM.
Heyyo, here's an APN list that might work better for you since it is updated by Google.

So this problem has been persisting for over a year now. I live in an area with great connectivity. All my family members have Jio sims and have never faced a problem.
Problem: I have two Jio sims in my phone. Sometimes my phone becomes unreachable or says 'number is switched off' when someone tries calling. If I try calling, it just shows call ended. The signal strength is always full and mobile data also works.
Restarting the phone or putting the phone in airplane mode and then back solves the issue.
Sometimes someone would call me, the phone would ring but I won't receive the call and then my phone would ring 30 minutes later and when I press answer, the app would hang.
Solutions I have tried:
- Factory reset my phone 3 times.
-Bought a new Sim
-Volte and WiFI calling is enabled, tried disabling also, but doesn't work
-Tried keeping Dual 4G on, it didn't work, tried turning off, it didn't work
Still problem is persisting
Please help, I don't have money for a new phone and I'm in the middle of job searching and I can't afford to miss recruiter calls
