I have a G960F. Just left an AT&T store trying to get this fixed, it's a national 3g shutdown. Data is still working fine but cannot make calls in and out. Everything was working fine last night. I guess calls are still operating on 3G even if 4G data is working. I'm wondering if updating to the latest ROM version would fix anything?
The model may not be hardware compatible regardless of firmware.
Do some research first.
Whitelisted are the AT&T and unlocked variants.

My S6 Edge SM-G925V worked perfectly back in India on Vodafone Band 3 LTE until marshmallow update. In the Nougat update verizon/samsung has some issue with their cellular firmware - after that i am never able to camp to any LTE network.
It was running smooth until the G925VVZW4CPD2 (6.0.1) update, all settings are ok. I tried the other popular network sim of JIO ( Band 40) that also is same. Bigger problem is that the modem crashes far too many times on the 2g/3G also. I can see the networks bar go and come in a loop again and again, making phone useless.
Verizon surely has messed something up with the latest 7.0 update, which they deny (have contacted them). There are couple of forums in Sammobile on the same. No luck with solution.
Just yesterday got one more update of 2GB which brings it to one update over 7.0. No luck. Still no LTE camping.
Do not suggest to check the APN settings i have checked they good. Anythings else or you also facing same issue ?
Can anyone show how to get the blocked service menu (via codes) working ?
Got the same problem. I immediately updated my phone from Marshmallow to Nougat via system settings.
I got the S6 Edge Verizon. Made several readings and found out that the device is unlocked, so I bought a local LTE SIM card (SMART) here in the Philippines and inserted it to the device. I applied the appropriate APN settings for the LTE and tested the connection. No luck. I wasn't able to test the LTE connectivity when I was in Marshmallow though.
I was able to connect to the internet via 3G connection and IT WAS WAAAY TO SLOW (0.5 mbps)
I tested the same settings with the Galaxy S5 (Verizon), still with a local LTE SIM card (SMART). LTE connection was immediately established (15+ mbps... not bad). This proves that my area is covered by LTE and the problem is on the S6 Edge. Is there a way to fix this?

I have the same problem, since the update I can't connect to LTE, I've tried forcing the 4g/lte network but it simply wont connect.
so no answer to this yet huh? issue with wifes phone so i cant call her during the day but text are still getting through thank god!
I installed the new update via the smartswitch. Sw ver: NRD90M.G925VVRU4DQF3
This also did not solve the LTE camping issue on international roaming as stated in original thread, infact the modem crashes so often on 2G/3G also (GSM/UMTS)
Anyone here from verizon/samsung who can pass on the message to relevant folks that there is a major issue which they have not addressed. I am surprised such a common bug was not tested before releasing offical binary for update !! #shame.
Any updates?

Any updates on a solution for this? I finally got around to updating my G925V OTA with Verizon, and I've run into the same issue. I hope I don't have to roll back the update manually but I guess I might have to because I have searched for a solution everywhere and have tried everything but nothing works.
Exact same issue, modem crashes constantly (I'll have signal on H/H+ only, and then it drops. Signal comes back. Then drops), and I never get LTE.
Tried all the obvious solutions (e.g. reboot, factory reset, network reset, clear cache partition, boot into safe mode, reprovisioning from carrier, confiming IMEI with carrier etc.) but nothing works.
What did you guys figure out?

waiting for the solution as well. But i rolled back to 5.1.1
SM-N9208
Android 7.0
Baseband version: N9208ZTU4CQH2
This phone was bought abroad in Taiwan and I'm now using it in US with metropcs. It was working fine for the last year or so and I think it broke in 7.0. I tried reverting back to 6.0.1 but still same issue so I'm guessing something must have changed.
When it is on 4G/LTE. I can receive text, data and it works fine. But it takes like 1-2 minutes to make a call out. I can't receive any calls on 4G/LTE. Receiving calls only works on GSM mode.
I did a factory reset and also kies recovery. I also tried it without restoring any apps so it is completely fresh.
If it's an international version it won't be programmed correctly for wifi calling / volte in the US no matter what you do. I ran into that same issue with my N920i and wificalling/volte/carrieraggregation. Not that I could use wifi/volte because at&t prepaid, but still.

It did work for about a year with 4G /LTE.. Either something has changed with the carrier or that an update broke the phone. I assume using a different radio firmware would not work as well? Note 5 is old but note 8 is really expensive and I don't want to shell out so much. Might be time to use google voice and redirect all the calls if I can't get this to work.
I'm experiencing issues with VOLTE on T-Mobile. My phone switches immediately from an LTE+ DATA connection to HSPA the moment a call is placed. Of course, VOLTE is enabled on the settings side. I'm running an unmodified system, upgraded to PIE.
I've been on the phone with T-Mo to make sure the APN is correct (nothing special to mention here). I've also tried different connection combinations using the *#*#4636#*#* with different results but, even though the phone connects really fast to DATA (LTE+), I cannot get VOLTE to function in any case. On the other hand, WiFi calling works just fine.
On a chat with Razer, they just told me that VOLTE is unstable with T-Mobile and, to disable the function altogether from settings.
Before I give up, I'm asking the geniuses here for ideas or experiences? Any ideas anyone?

I hope this can be figured out. Im waiting for my Razer 2 phone delivery and also on T-Mobile. What OS are you running? Android Pie?
Yes, I'm on Pie.
Good news! with today's update (3-20-2019), my phone is using VOLTE technologies to connect audio calls. Phone calls sound immensely better now (the "HD" icon shows up during the call and the "LTE+" connection indicator in the status bar remains through the call).
I have knox tripped but completely stock SM-N960F/DS that has Verizon VoLTE working perfectly fine !!!
I have an international SM-N960F/DS from ebay a few months ago. I had to install custom rom to get it work with Verizon. Hence Knox tripped.
Today, because of other reason, I decided to flash a stock rom to it. I took N960FXXU3CSF9_N960FOXM3CSF9_XSP which is for Singapore, and flashed to it and turned it completed stock except for tripped Knox. Afterwards, got an OTA update via wifi.
I have a already activated Verizon Sim and a Google Fi data-only sim, and they somehow work fine with stock rom. Verizon sim had VoLTE option, and registered IMS. I can make phone calls, text etc. obviously, there is no wi-fil calling or video calling.
I did have problem right after setting up the phone to get the sim cards to grab on signal and/or get LTE data turned on. took sometime to get them working, but once LTE worked, the VoLTE worked all the time. I did setup the phone without sim, and then put sims in there. in order to get signal, I had to get the phone on in a strong signal area for 30 min or so, and had tried to move sim around different slots or put one sim in first etc. I don't even know what worked at the end, but after an hour or so of different tries, now both sim cards worked well, and I can make phone call and receive phone call via Verizon.
Maybe Samsang finally did something to CSC to allow VoLTE. but if this is true, quite significant, as international Note 9 now works without any modification in at least Verzion if you don't need wifi calling or video calling.
I don't have T-Mobile voice sim card, therefore, I can't get if VoLTE works T-Mobile or AT&T.
Hey so I've had my Rog phone 3 for over 3 months now, updated to A12. A constant problem has been the mobile network. Works fine for WhatsApp, but for normal browser (different browsers), other apps requiring internet, though the mobile data is on, it acts like it's offline, showing offline. I have to toggle on and off airplane mode for it to eventually work. Then if I turn off mobile data and turn back on, the cycle repeats. Please help
I'm having the same issue here too. The A12 Beta had choppy Network Connectivity that would just crumple my phone and not allow me to use Communications or Data, the random disconnects were absolutely infuriating, and after updating to the stable build, it was just not allowing Mobile Communication at all. (No Incoming or Outgoing calls)
I'm extremely happy about the downgrade FW however to allow me to revert to A11 that at least allows my phone to function as intended, even if I cannot enjoy the update that A12 has to offer.
Downgrading from A12 to A11 is an Upgrade. A12 has little to offer beyond making your OS look like a kindergarten app ...
Upgraded to A12 last night with the OTA. Data is fine but I cannot make calls, network immediately drops. no other issues with the phone though, 4g data works.5g never worked but volte did (At&t network) VoLte doesn't show up and I cannot find a place to enable it however there is a toggle for it in notifications. I spent about 3 hours at AT&T. So. here is info if it helps anyone. They told me that the phone is somehow locked to 3g calling even though the sim card shows LTE voice. After the update only calls dont work. The guy said he helped me before by provisioning an older sim card and using VoLte, however from what i understand The phone Does support more than 3g voice but if someone can correct me that would be cool. Also I found out if I put a sim card from an ATT iPhone it will connect at 5g (20mbps speed tested). I said well if I lose voice and have to figure out a wifi calling plan I would rather do it with 5G, however when they provisioned a 5G sim for me on my account it wont link above 4g+ (1-3mbps) same tower. So im at a loss. I know part of it is the new android 12 update, I know some of it is the stupid account provisioning and i know some is the phone. I DO NOT know what is what so any help would be awesome. If there is some way to add VoLte back to the phone in android 12, flash a new radio or something... but if someone can shed some light onto what is really happening so I know where I can press that would be slick. if the phone does communicate through something other than 3g voice then I can push back on At&t but i have kept this "less" a development platform and more a daily driver. I guess that has to now change LOL!

Any developments on this? I am having the same issue.
Mine seems to lose connectivity after returning from do not disturb or when I'm inside with no signal for a while. I have to toggle airplane mode for sec, then I can use the phone. My wife texts me a few times a week, "It's going straight to voicemail again.", then I toggle it and call her. It will work fine for the rest of the day. Doesn't happen every time, though. Bizarre, though most of the time it's in the morning after returning from do not disturb mode. Kind of a hassle, but I'm coping. I'm going to start logging when it happens to see if any settings may be causing this.
