Short version:
The phone works good initially, but once I move out of Wifi (so that phone's data connection takes over) and move back in, calls stop working. No incoming calls, no outgoing calls. data, incoming texts all work fine. Just no calls. I even get the text from the service provider that I missed a call.
This happens in stock 20d, 20f, 20h, and CM10.2.
Has this happened to anybody else? Did the delay in installing radio_fix (see below) caused the problem?
Long version (history):
I used carloswii5's method to unlock bootloader (http://forum.xda-developers.com/showthread.php?t=2277639), and load CM10.2.
At the end of the method, I forgot to install radio_fix and used the device for a couple of hours, all the while wondering why the radio seems very weak and why I am going in and out coverage in the middle of this metropolitan area.
I eventually realized that I forgot the radio_fix.zip and installed it. The phone started working properly at that point, with signal levels comparable to other phones.
The trouble starts when I move out of Wifi area and THEN MOVE BACK INTO (OR MOVE INTO SOME OTHER) WIFI area. At that point, I am unable to make or receive calls. Outgoing calls do not result in any tones at all. Incoming calls get a number-unobtainable tone (beep beep). It doesn't matter if I then turn off the WIFI. The calls will not restart until I restart the phone.
I then went to CMahendra's CWM backups thread (http://forum.xda-developers.com/showthread.php?t=2136204) and installed 20d, 20f and 20h one after another, and then back to CM10.2 The exact same thing happens in all the versions of stock and CM.
I am on Lycamobile. Stock versions recognize the SIM correctly as Lycamobile while CM10.2 thinks it is T-Mobile. It doesn't matter though, since both the coverage and eventual issue of 'no calls' is the same in both versions.

I recommend performing an offline flash of 20h to install the proper radio. Or do a search in the threads for the 20f flashable zip by lelus. If you still have problems it might just be your phone.

I did an offline update with V20f_00.kdz. The issue persists. The strange thing is, data continues to work and text messages come in, but only calls fail to come/go.

You must have a hardware problem or maybe it's the area you're in.

Other people have reported the same problem on cm 10.2. I wouldn't be surprised if t mobile ****ed up on on their radio blobs.

It'll receive/send texts perfectly fine (well, it'll give me an error but it still sends it).
It happens so often, it starts to get frustrating.
Does this happen to anyone, if it does, any help?
(If it helps, I'm running BAMF Sense 3.0 RC3).
I can't use the phone function most of the time. When this happens, I usually have to do a battery pull, or a soft reset. Usually when I do a data wipe, it fixes the problem.
But how can I stop this problem from happening and make my phone reliable again?
You never explained exactly what it is that's happening that is making your phone unusable. How does it not send/receive calls?
sorry for the clarity.
but basically when I receive calls, they go straight to voicemail.
when dialing an outgoing call, it won't ring and the phone will say "call was lost", even when I have full service.

Have you try on stock rom and does data work ?

I just wiped everything clean. Data works fine and I'm able to send texts (but I receive a warning) and receive them too. Phone calls don't work. Do you think its a problem with the phone itself?

Should call Verizon tech support if I were and run stock ota update , they might be able to help you more then us right now

Hi Everone!
I bought a Verizon S6 Edge+ a few months back. Ever since, I can only make outgoing calls ~15% of the time. The rest of the time, when I dial a number, it thinks about it for a little bit and then just ends the call. Incoming calls work perfectly fine. I tried the following things:
1. Changing mobile network to Global - sometimes allows me to make the call, often time does not.
2. Taking out and re-inserting SIM - doesn't change anything
3. Toggling airplane mode - doesn't change anything
Any ideas of what I can try? Thanks so much D
I had same issue, followed instructions from (https://www.getdroidtips.com/g928vvru3cqb9-nougat-s6-edge-plus/) to rollback to previous version of Android i.e. Marshmallow (https://forum.xda-developers.com/s6-edge-plus/general/g928vvru3cqb9-odin-nougat-7-0-firmware-t3601427). Able to roll back, but that did not work, So used Verizon update tool to update back to latest firmware, now it works fine. Give a try and see if this helps.
I'm having this issue with an AT&T sim.
Global: Data is at H+ and can make calls.
LTE/CDMA: 4G LTE Data works flawlessly but cannot make calls and gives me an error stating "incorrect sim or sim error".
LTE/CDMA/UMTS: 4G LTE Data works fine however when making a call data goes back to H+ and stays there.

Can you explain more info? what version where you on before rolling back, im having serious connections issues since upgrading to android 7 and that 6.01 rollback looks interesting, my service worked just perfect on 6, when i upgraded to 7 my phone became unusable and wouldn't receive calls or texts unless i connect to the network every 15min with a call to my vmail. weird i know
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
Just bought a Z5 compact to replace my second Z3 compact... and upon backing up DRM keys and then re-flashing, unlocking bootloader, flashing recovery TWRP to install a ROM, have tried two variants of LOS and two other ROMs... NONE of which can receive calls.
what.the.actual.****.
all calls go straight to voicemail.
some outgoing calls simply don't go through (need to try 2x or 3x to even get carrier support)
and occasionally, when trying above, dropped "no network" and phone signal resets.
i've tried re-flashing various .ftf files (i'm based in US and am using a US based .ftf i compiled now... with clean flash).. nothing seems to be working. all symptoms the same across all .ftf files and ROMs.
about to return the phone as i can't crack this one. (but have years using /rooting android devices - never seen anything like this).
any ideas??? all help appreciated!!
thanks in advance.
Sounds like there's problem with the antenna?
Having the same problem. Nothing wrong with the antenna--can make calls, just takes 2-3 tries. I suspect that it possibly has to do with handover from 4G to whatever it's using for the call (the handover is too slow), and/or the fact that VOIP isn't working with my carrier (US T-Mobile).
Try forcing it to 3G (WCDMA preferred/GSM) in Settings > More > Mobile Networks.

This does fix the problem with incoming and outgoing calls (I set it to 2G preferred, not to 3G). However, as a result, you don't have fast internet access (which, of course, is necessary for basically everything the phone does minus SMS and plain old phone calls).
I went into the "Testing" menu (dial *#*#4636#*#*) --> Phone information --> three dots in upper-right-hand corner --> Select Radio Band --> US, or whatever's appropriate. This is leaving 4G preferred.
Based on very limited information (a couple outgoing calls that took only one try), things are somewhat better. I could be wrong, though: I haven't had any incoming calls (...that I know of).

Is there a good app that will auto drop to 2g when screen is off? I used to do this to save battery life, but sounds like it would also help solve this situation - agree that symptomatially, sounds like the issue is switching between 4g and 2g/3g - so would love to give this a try.
Any ideas on reco apps to set "2g when screen off" ? and also enable a widget that will force switch?

It's an Xposed module afaicr...
My phone did actually ring today (...spam, but still). I think the change in the Testing menu, as described above, has made a real improvement.

i've gotten SOME rings that come through and some that go straight to VM.
I've also seen my phone "pause" or "hitch" right before taking an incoming call successfully (suspecting this is the 'difficulty' we are guessing about between switching from 2/3g to 4g or vice versa which is causing problems)
half my calls still going straight to VM. Which actually isn't a horrible thing. except when i want to receive them. lol.
I guess its a issue with the baseband aka modem.
Try to flash different versions and recheck. It can take some time to find the besteht baseband for your area and provider.

Is it possible / advisable to flash *just* the baseband? Where would one find files for just the baseband? I'd prefer to avoid extracting from .ftf , but if that's necessary I'll do it.
Has there been progress with this? This is exactly my problem, faulty reception. Glad to hear you used a stock US rom. Mine is stock Australian, I am in US. So that seems not the problem. What about kernel? Have you tried different ones or compiled something? It is a software problem, should be solvable.
To flash baseband only get a .54 firmware ftf, flash it, in the exclude section - exclude everything but amss stuff and baseband. I will edit post with exact names cuz I'm outside rn
Edit: AMSS_FS_1, 2 and FSG and also MODEM.
Unlocked phone on T-mobile, US.
I'm not sure when this gets started, but I've noticed it after the April update. When on VoLTE, there's no sound for incoming or outgoing calls. When on WiFi Calling, it auto hangs up as soon as the call is picked up.
Any input is highly appreciated. Thanks in advance!

I had an issue recently where all calls I made (wifi calling or though the stock dialer app) would auto hangup and never go through. Incoming calls seemed to work fine though.
I did a factory data reset and set everything up back from scratch, that was the only way to fix it. This maybe something worth trying if you haven't done it already.
If you do a restore of any backup data (i.e. smartswitch, google backup) I would suggest using the google backup and not the smartswitch this time. I made a smartswitch backup before the factory data reset, but ended up not being able to use it. Everytime I did a restore with the backup the same thing would happen. I had no problems with the google backup.
Also if the problem persists (or if you opt to do so anyways, maybe worth trying anyways) I would call T-Mobile support and ask them if there are any problems or etc. It maybe possible they are working on the towers near you, as one time my service was being a little quirky and it was due to them doing some low/mid band additions on nearby towers. They may just need to refresh your phone on there end or send you a replacement sim card in case a problem exists with the one you have..

Thank you so much for the input! I'm going to factory reset this evening. And if it still persists probably call Tmo. But I guess the chance is low, my other device works just fine with Tmo (both wifi calling and volte)
Let's see! Have a good one!
