So, my phone can't make calls and I've tried everything I was able to find online to force it to do so. I took my sim card from my moto x and put it in you'd nexus 5x, but when I try to make a call it immediately hangs up. I've gotten a new SIM card and gone to multiple Verizon stores to fix it, to no avail. Lastly, I heard that I could make calls inever i enabled advanced/hd calling so that i could use data for the call. Whenever i go into testing settings to make the VoLte work and reboot, it seems to not keep the setting. I'm lost, and I just want to make calls. Any help?
In the past (16 years ago, in times of Siemens S55) there was a way to enable a second line on the mobile phone. I think it was something like pressing 0 for a few seconds to switch between the lines.
When activated without access to a second line, you were not able to make any phone call. Not sure if this function is still available at actual smartphones. Only a hint where you can search for.
Or, another hint, you've activated the call restriction (not sure if this is the correct translation from German). In the options of the phone you're able to block some or all numbers for outgoing calls.
Try to check in test menu (*#*#4636#*#*)if the phone is on LTE-only mode and put it on LTE/CDMA/UMTS

My H798 came across bootloop, after a fix from Huaqiangbei, Shenzhen, was sent to me today. The phone runs into a similar issue. Data and SMS work well, while any call will be held on "Calling…" for 30 seconds, with no sound, then end up with a beep of hanging up.
But my mobile carrier is China Mobile.
Same thing here, replaced with chinese motherboard and now no calls, but sms and data works fine.
It seems that there are different SMC for 4g and 2/3G, so it seems that there is a hardware fault on the 3g/2g chip.
Gonna try to gunheat it.
I have a HTC One M8, AT&T, TWRP recovery, flashed and rooted with ICE 8.2.2; SuperSu.
When I am connected to 4G/LTE and someone calls me, it rings on their end but my phone does nothing. I checked my IMEI and see LTE is supported. When I switch my mobile network from 2G/3G/4G (auto) to 2G/3G (auto), it connects (H, H+ icon) and my phone receives incoming phone calls. My SIM card does not mention "4G" or "LTE". I have yet to try the SIM in another phone yet but plan to tonight.
Just to help me out with my thought process on figuring out the issue I'm going to think out loud for a second:
Put my SIM in another phone and make sure 4G/LTE is on, check if it receives calls. If it works, the issue is my phone or ROM. If it doesn't work, SIM card is the issue.
Also, from what I understand, phones on 4G switch to 3G when a call comes in and my phone may not be doing that. Is there a fix for this?
EDIT: As additional info, I am able to make outgoing calls without issue on 4G.
Are you actually using AT&T as your cell provider?
Yes, and I made sure my APN settings are correct.
It's a known issue. AT&T's implementation of Voice over LTE (VoLTE) which they call "HD Voice" for some reason interferes with voice calls on custom ROMs on this device.
No real fix, aside from calling AT&T and asking them to turn off the HD Voice feature of your account. May need to ask for a 2nd Tier tech support to do it. Others here have posted they had to do that (and 1st Tier either had not clue what they were talking about, or wrongly claimed it can't be turned off).

Awesome. Thank you!
EDIT: Just finished working through the issue with an AT&T rep through online chat. Had me turn off my phone, disabled it on their end, and turned it back on. Did a test call and sure enough 4g switches to 3g as the call comes in and switches back afterwards. Problem Solved!
Hi!
I am occasionally unable to receive or make calls on my XZ2c. Specifically, sometimes (say, every few days) people report to me I cannot be contacted although I am in a place where I have good reception. And, in such cases, if I try to make a phone call myself, I cannot. Even more specifically, the caller in these cases hears no ringing and no typical carrier voice message that my phone is off or that I cannot be contacted for the moment; while, when I try to call, nothing happens for a few seconds and then the phone app stops stops trying.
A restart always solves the problem.
Also, it may be the case - but I am not sure - that this happens after the phone has briefly lost reception (for example, in my office, because I exit the elevator, or in my home, as I have a blind spot in the courtyard). This seems to me to be the case based on a few observations but, again, I am not sure about it.
Otherwise, the phone works impeccably, but since I missed a few crucial calls recently this has started to bug me. (Needless to say, my two mostly retired phones, the XZ1c and the OG Pixel, do not have this problem when used in the same environments.)
Any suggestions, please?
I have the same issue - and reboot suddenly resolves it. I've tried to ask over Sony forums, but no reply yet. It bugs me also, but it would be quite hard to report it to Sony service center, as I cannot reproduce the issue myself. (although I think they are aware of the issue) It's a bit strange that my XZ2C has reception problems where my Z5C used to work...

It would help if you would report what carrier you guys are suffering the problem on and whether volte is enabled and if you have tried more toggle options of which networks to fall back on to make sure you receive calls, there is a way to manually set it to fall back all the way to GPRS 1.5 G manually haha my carrier supports that and i was once deep in the forest and still recieved a 1g call haha. It is not enough coverage on weak signal for 2g or edge calls.
In some cases inside big city where they ONLY have either LTE or WCDMA ON THE NETWORK, then YOU MUST either force it to use LTE only, or wcdma only. That way it does not jump back and forth and miss call. Some big cities i set it to lte only and even in basement or in skyscraper it is always full bars. So it just depends which tower types are in your home area.

It's Telenor Hungary, no VoLTE or other "magic" involved. There was a previous thread, which discussed the same issue. Actually I posted it to talk.sonymobile.com also, but please see the attached screenshot - it shows the actual issue. Telenor Hungary shows up as "emergency calls only", while Telekom HU and Vodafone HU seems to be fine. Sometimes switching airplane mode on/off solves the issue, sometimes it's a reboot which makes me able to make/receive calls again. But forcing 2g/3g/lte does not have an effect for me.

If this is the case, it is the SIM cards identification is not consistent to the network tower. Maybe the carrier has updated sim card version if you ask them. If it is emergency calls only logically its the network not authenticating your account based on sim card. It may be sensitive to the phone hardware. I have heard some people on other phone models hadd to ask carrier to provide even old version of their sim card instead of new ones. Try that.

Thanks, I'll give it a try today and ask them to replace sim card. Hopefully it will solve the other appearance of this issue also: whenever I have full bars and talking (usually late night driving home to parents, in a well-covered area), audio quality degrades in seconds - at least on my side - and other party is not able hear anything I say. After disconnecting - if I'm able to do so, and phone app does not get stuck with "call disconnecting" message - I'm not able to make/receive new calls, as only the outline appears of signal strength bars. After restart everything works perfectly. Strange, isn't it?

Ironically - or maybe not - I am not that far away. I am on Orange Romania. When I search for networks I get essentially the same picture -
Thanks, I will try the SIM trick as well, maybe it helps. I may even go as far as jumping carriers, in fact.

Got my sim card replaced, now waiting for the issue to pop up again. (or hopefully not) Actually the guy at carrier said my "white" simcard (about a year old) was a problematic one, replaced it with a new. I don't know if this could be true, but hopefully it'll solve the problem.

It seems that replacing the sim card solved the issue, thanks for the hint! I would have never ever thought that a sim card issue may cause such a problem.
I have exactly the same issue and have already a new sim, which doesn´t do the trick for me....any other ideas how to solve this?
no VoLTE or anything like that. T-mobile as carrier

No longer have this problem with recent firmwares. The sim change did not solve the problem for me.

Thank you for the feedback.
With the recent firmware you mean 52.0.A.8.50 on android9? Do you use stock rom or a custom rom?

What an irony! After updating to the latest fw some 2-3 days ago, it's happened again, the first time in some 4 months.
Nooo... I just got my replacement phone today and so i installed all the latest firmwares.... I still have high hopes i won't be affected again.
Has anyone any idea how many phones are affected this way... Can't be all of them otherwise there would have been a flood of threads about that.
Maybe some prior models of this series...

Did you test different firmware regions?
Maybe your mobile network provider and the baseband aren't compatible (bug).
And did you report Sony that the bug is in the newest firmware?
No i've just used the original settings since i am still in warranty time
But that's why i've asked before if the others were experiencing this issue only with their stock or even with custom roms / fw.

For that, do you mean to change the settings in the play store or which settings are you referring to?

Just use xperifirm and newflasher to apply a different region.
But remove the userdata.sin if you don't want a full wipe.
hi everyone, i have a lg G7 EMW for almost two years now. as said my phone its an EMW, although I use the EM variant ROM for more than a year because of the lack of updates. never had any issues before.
some weeks ago i had to make a call and noticed it was not working, at first i though it was a cover area issue with my carrier, since it was a place a little far away.
but in the following weeks i started noticing a lot of messages saying 'a number called you and did not left a message' and them i realised that the phone actually never ringed, so i started making some tests and realised it was not making or receiving calls.
i cannot acess all the settings in 'call settings menu' it return me an error saying "network or sim card error" but my 4G internet connection and SMS in the other way, works fine.
I already tried my SIM card in another phone, It worked normal. then i tried another SIM in my G7 and it has not worked also.
i have also tried to go back to my country open rom in a fresh install, but nothing changed.
yesterday after receive a cell broadcast notification, it worked for a short period an them stopped again, so i suspect may be some problem with the network, seems intermittent somehow
have any of you faced similar issue or know any solution? is there something i can do in service menu to see if its a hardware problem?

There were networking changes, so you need a sim card that is compatible with these changes.
If your SIM was purchased two years ago, it may not be compatible.
Just contact your phone provider, whoever it is, and ask them to sell you a compatible LTE Sim card. I had to buy one from Net10/Safelink for 99 cents, because the one I bought two years ago from Best Buy for "Net10" was not compatible with the new changes. All phone service providers should have a "buy your own sim" program, so just contact them for it.
check all necessary information in phone's settings about section.
Is any information missing there or blank?

i can give that a try but i'm not sure, my LTE and SMS seems to work normal, it is only the calls the problem.
the other SIM card i tested on my G7 was from a different carrier and the problem persisted
also my sim worked normal on other phone (Moto G5 Plus)

Call your carrier and ask them if they are using VOWIFI and VOLTE for their calls now.
The phone falls back to 3G mode on calls.
If the SIM or the tower you connect to is not provisioned for VOWIFI/VOLTE, the calls will use 3G.
if the tower is provisioned for VOWIFI but your SIM is not, then the calls will fail. SMS will not fail since that's LTE already.

This problem arises when particular phone has lost phone identification numbers such as S/N, IMEI SV and mainly IMEI. if it's the case then you must try flashing latest stock firmware for you model.
Greetings,
I have got a Pixel 6P device from the UK Google Store.
Since then I had to move to Hungary and started using the device with local carrier T-mobile (Telekom Hungary) and using physical and esim also.
Both of the SIM cards has connectivity issues. The signal suddenly drops to zero, and I only get a carrier notification SMS for a missed call.
My network signal usually really bad. I also tried using 5G near a 5G tower but it just won't connect.
I tried to connect to VoLTE or Vowifi but both of them is disabled on the phone. However the carrier has enabled it for both SIM card and I have got the confirmation messages of it.
I tired factory reset and SIM card replecament with no luck, problem is still there. Carrier just said that that everything is fine at their side...
I have waited for the december update, and I did the update with ADB sideload.
Now the connectivity problem is still there, and I have got another big problem.
When I get a call, and pick it up I don't hear the caller and caller can't hear me neither.
If I put the phone to loud speaker and back to normal then I get voice in both sides, tried phone restart but it won't solve the issue.
Has anyone encouterd with this problems and managed to solve it?
By the way after the a December Update my battery life has been significantly better.
Thanks
Hi,
I´m experiencing the same issue on P6 (non-Pro). How did you sort that out?
I remember reading on here that somoen in uk was on three network which is certified with Google but if you use the pixel 6 and pixel 6 pro on smarty which uses three won't work on pixel 6 or 6 pro
https://support.google.com/pixelphone/thread/146634713/would-it-be-possible-to-have-5g-please?hl=en this was link that's simlar I did check t mobile to see if they sold the pixel they seem to sell it sorry I didn't or couldn't help
