I have a really frustrating problem with my S5 (900F) where I can't make or receive calls.
I initially assumed it was a bug in Cyanogenmod 14.1, as that's when I first noticed the problem; however today I have flashed stock firmware on the handset and the same problem persists. I can see a signal and if I disable WiFi I can see HSPA/3G data in the status bar and can browse, but if I try to make a call it immediately disconnects and I cannot receive calls either.
I have moved the SIM card to another phone and can make and receive calls there, so I am sure the SIM card is OK.
Any suggestions would be gratefully received!

I bought unlocked, sim free HD2 inserted the sim of my usual Mobilink network the phone wizards automatically configured the setttings but to my strange I cannot dial or receive phone calls, I am receiving and sending sms perfectly the phone GPRS working alright tried different methods of changing band but nothing is working to dial or receive voice call. In order to check if there is problem itself with the phone I tried different network (Ufone) sim and the phone is working perfectly without any problem so I am stuck that I cannot use my network which I normally use and I dont want to switch network, if somebody can help to fix this problem.
hello
I have had my note 3 or about a week now.
I cannot successfully make calls. I can receive calls and do pretty much everything else. Browse internet, sending texts etc.
As soon as i dial a number it takes a while to connect and then it ends the calls.
I am on Three. uk
I have tried with wifes Sim and the phone also fails with her sim but my sim works fine in her phone. so can rule out problem with the sim.
I have tried changing caller id to network mode as read that fixed Galaxy s II devices but that has not worked.
I have tried messing about with the different types of network mode. Only GSM mode works.
I am getting a full 4 bar signal.
I am on stock firmware SM-n9005
baseband n9005xxudmj7
build number jss15j.n9005xxudmk2
Anyone got any idea why this is happening or how i can fix it without sending phone off for repair ?? I have read elsewhere that the December update might have caused an issue like this ?
Many thanks

Try factory reset with your wife’s sim inside, if still same problem I think service centre is only option.
by any chance, have you set your network mode to 4G only? cause afaik, the phone wont receive call if youre on LTE 4G only mode in network. once i too cant make a call when i set my network mode to LTE only, then i choose LTE/GSM/WCDMA auto, i can receive and make call again
Thanks.
I have tried reset and this does not work.
its definitely not on 4g . I have tried all the network modes and the only one that works is GSM... I dont want to leave it on GSM though as i want to be able to connect to internet whilst out and about.
Seems a bit ridiculous though that i cannot make a call on a phone. Will be off the the three shop tommorow.
Hi Guys,
I have a G900F and it has started to give me a weird problem. My phone is not showing any network bars, I cannot make any calls or messages and receive nothing as well but my data connection is working fine and I can use 3G without any problem? I have tried reflashing the rom from scratch. My IMEI number is showing fine and the SV is showing 01. The Network is in Unknown State and Voice is out of service but data is in service. Kindly help please.
I own a SM-G935V that I'm using with Tracfone. It's running 7.0/Nougat, patch level 4/1/2017. On another forum, here's what I wrote:
I've run multiple tests on this and it turns out that if I reboot my phone, I do not get reconnected to cell service unless I make an outgoing telephone call.
The reason why I didn't notice this is because I use Google Voice for about 99% of my SMS communication. So here's the test I ran:
1. Reboot phone, wait until it comes back online and I have bars and 4G on my status bar
2. Call my phone from another phone -- goes straight to voicemail
3. Send SMS via phone's SMS -- goes to pending and is never sent
4. Make an outgoing phone call not using Google Voice but my cell network resolves the issue
I've changed the network from Global to LTE/CDMA, but it makes no difference. I've also turned off the wifi and tried to see if I would be denied for data access, but that is not so -- I can visit websites without any issue. But doing that DOES NOT reconnect me to my cell network. So it seems that since I'm using 4G/LTE for data, that authentication is separate from the cell authentication.
I got a response from another user that's experienced the same issue. He said he had no problems with Verizon prepaid SIM but the same exact thing with a Tracfone Verizon-piggybacked SIM. His solution was to push an unbranded firmware on it.
I'd rather not go this route if I can help it since the phone works well and this is the only issue I've encountered. Any suggestions?
Hello,
I have got the odd situation with the SM-G950FD (Singapore non-branded XSP CSC) living in the UK and using the Vodafone UK network whereby I am unable to make VoLTE phone calls although I have got the VoLTE function enabled. I first thought it was because of the network, however I came to notice that I am able to use VoLTE to make phone calls when I make them from my car over Bluetooth. It is of course the same mobile phone, and I can confirm VoLTE use as the display continues to show 4G+ or 4G whilst on the phone instead of jumping to H+ or H.
It seems as if phone calls over Bluetooth must be triggering a different call initiation routine compared to making a phone call using the dialler on the phone itself. Has anyone encountered this before and has anyone an explanation for this? How can I fix this so that I can VoLTE phone calls from the phone directly as well?
Thanks
Wolfgang
