Stock Rom Carrier Unlocked not able to receive/send calls but can use data and SMS

Hey,
So I bought an LG G4 from Vodafone UK and unlocked it so i could use my Three sim card.
Weird thing is I can use Mobile Data and send/receive SMS if I am on 4G. The person who is calling me can hear the calling tone as if they were calling someone but I don't actually receive the call.
When I switch to 2G/3G it simply does not connect to the network.
I have done a factory reset and it did not fix the problem.
Any ideas?
Thanks
tl;dr : can't send/receive calls but can use data and send/receive sms (through 4G only)

Maybe you need to register your IMEI on the network? That's what I had to for At&t.

How would you go about doing that? Apart from manually searching for networks (I can see other carriers like O2, vodafone, EE, but I can't see my carrier Three ; the person living in the flat with me is on Three as well and they have no problem, so it's not a coverage issue. I have bought the phone from vodafone, unlocked it and trying to use it with Three).
Do I have to call Three for this IMEI registration or..?
Thanks

Best bet will be calling your service prover and have them register it. I had to call At&t and have them register my IMEI since I couldn't use internet or make calls.

Just had a long chat over the phone with them and in the end he said the 'engineers' found a 'problem' on their end and it should be fixed in @5 days. He didn't want to mention what problem or how / why it happened. Oh well fingers crossed.
Thanks!

update : so after about 4 calls with customer service (across 3 weeks) and 2 trips to the 'Three' store i'm basically stuck and would need your help guys.
backstory : I've contacted them once at the start of January and they said they found the issue and they will fix it by 7th of January which didn't Happen. On 7th of January they said they are sorry and it will be fixed by 14th of January which didn't happen either. After that I received a message that the problem was fixed and if i had any other issues I should contact them, which I did because the problem was not solved. Yesterday I went to the shop again and the 'tech' guy told me that it should be working and he gave me a new sim card just to be sure, and if that didn't work he said call customer support and ask for contract cancellation. Today I got called by customer service and I have told them that it still doesn't work and I'm paying for something I can't use and I've been told to request contract cancellation which they didn't believe and said I have to pay the rest of the contract length in order to cancel, which is absurd. I went again to the shop and the new customer service person that was assigned to me said they don't have any tech people and she seemed she didn't believe when i said i talked to one the day before. She tested the sim on their phones and it worked and also she took my phone "in the back (strange cause she said they don't have any tech)" and said I had my phone set to 2G (which I didn't, it was set to 2G/3G) and that that was the problem. strangely, for that split moment i had one bar for 3g and the call went through. Straight after that phone stopped working (it was just that small area in which it worked). I told her that that's not the problem and she's like "welp you didn't make your contract at the store, you made it online so I can't help you , you have to call customer service". So I'm basically stuck with a contract which I can't use and I have no idea what to do.
problem : I cannot register to the Three network (only in small random areas, few of them) but I have no problems with other SIM cards from other Carriers (Orange, EE, Vodafone, O2). I have bought the phone from vodafone and unlocked it and last time customer service told me they can't give support to phones that were not bought from their store. So I'm stuck here with a phone contract which I can not use to make or receive calls, but I can use the mobile data and send receive texts. I am considering rooting it and puting a custom ROM , although I'm not sure if that would fix the problems (maybe issues with certain bandwiths?.
Any help or ideas much appreciated!

Same problem here
Hi all. Same problem here but different issue.
Origin : G4 buy used on November. IMEI fully working and not blacklisted (calling my french phone provider this morning, it tell me that's IMEI is ok and phone not stollen and it try to repair remotly my carrier but didn't work)
Problem : Fully working since i picked up a call and answer ... and then when the call is finish i tried to call someone 10 minutes after and totally loose signal(connection) (Orange/Sosh)
What i've maid before : Playing a lot @ a boring but adictive game. High temperature since 3 days because i play a lot but temperature decrease when i stop playing.
I've used a legal app to record a patern and make some actions without my intervention (RepetiTouch Free (root)) to make races in the game.
That's all ! No drop, no hit, nothing ! Just playing, having a call, hang off and then want to make an other call and nothing.
Since the last 6 hours : Signal ok - Data ok (can go on internet / GAPPS etc..) - CAN receive and send SMS (i've don't trie MMS) !!! but .... can't receive and can't send any call.
I was on Genesys 3.5 and i've update to 3.7 when i see the problem, believing that's it will fixe the issue but ... no ....
Formating and going to stock ROM but with root SU etc..... Can't receive and send call too ....
I'm going to back to stock with KDZ .... but i really believe that's it will not work .....
AND .... to finish and kill my joy .... i've unlock bootloader with LG tools since 2 month .....so my phone is no longer under warranty.
My SIM card work on others phones ... other sim cards didn't work in my phone ....
If anyone have this issue ... please tell us

Sorry bro cant help you here. Never heard of that problem before but my idea is that you should refund that phone back to Vodafone UK.

Verizon HD & Video Calling

Has anyone been able to use HD calling & native phone dialer video calling? I have both features turned on through the verizon website/app & also on settings/networks & also on the phone dialer settings but I don't see it when I make calls.

I've had the hd voice calling activate on its own when I call a friend with an S6 on Verizon. There were no prompts but my dialer showed "HD" during the call and the audio was much improved.

I think the "much improved" is very subjective. The person on the other end sounds unnatural to me... Maybe its the years of ****ty audio quality that Verizon has forced on me.... But I'm not a fan. Besides it is fairly worthless as the other party has to be a compatible verizon phone. Most of my calls, other than my wife, are on other networks or land lines, where the HD does not come into play...

HD calling works for me (Shows the HD icon when Codec is AMR-WB). However video calling does not. If I force Video calling provisioning. It turns off after reboot. Works on my buddies Pixel XL however...

I'm on Verizon also and HD calling works for me. I haven't tried video calling but it shows up for some contacts.

I'm in the same boat. All settings and provisioning activated, but don't see the "HD" icon on calls, or anything related to video calling.
Let me know if you figure anything out.

Both work for me. Video calling icon comes up when on call and hd voice icon as well.

I haven't been able to test HD Voice, but I'm finally seeing options for video calls in the dialer.
*I think* this is what fixed it:
-Dial *#*#4636#*#*
-Select Phone Info
-Make sure provision boxes are checked for VOLTE, Video and Wi-Fi Calling
-Reboot, just to be safe
-Go to Wireless & networks settings and select Network settings reset
-Turn off Advanced Calling and turn it back on
-Reboot

When people with Verizon call me, I get HD Voice but when I call them, it's standard quality. Wtf Verizon/Google...

Video calling and HD work for me. I have the Google version, not the Verizon one. It's nice to be able to switch during a call but the quality is often bad even with a good connection. Google Duo seems to work better and works with iPhones and all Android phones.

Dangit!
I thought I was all good, but I have the same thing. Incoming calls are HD, outgoing are not. Or if they are, there's no icon indicating it.
Still can't get Wi-Fi calling to activate, also.

I'm on Google's support chat right now regarding the HD voice with outgoing calls issue on Verizon. I'll post what I find.
Edit: they kept trying to tell me it was Verizon's fault. They said I either didn't have HD voice enabled on my account or I had a service issue both of which are wrong. I've triple checked my account and it wouldn't work when someone called me if it weren't enabled. Also, it doesn't matter where I am, the issue always behaves the same. Outbound calls give no HD voice but inbound do.

HD outgoing and video works for me. Gs pixel on 7.1.1 but it worked on 7.1 too. Works on both wifi and LTE. Wifi calling is switchable also.
I'd say get a new sim card. Sometimes vzw tech can reprovision the card properly. Sometimes it's easier to just get a new one. I've had weird stuff happen where only one side of the conversation can hear the other and only a new card would fix it.

Thanks. Good to know there are some Pixels on Verizon out there without issues.
I'll try the new sim. Mine is at least three years old--maybe four!

Can anyone explain why when I try to Facebook call, video, etc data drops instantly? It happens every time. I have unlocked Google PIXEL xl.

S20 Ultra Exynos missing calls intermittently

So I have used my S20 Ultra since March this year.
I've noticed that the cellular network just "sleeps" and doesn't receive calls/SMSes after some time of phone idling/usage on WiFi.
I tried googling and found many other users reporting similar issues, noticing also that it seems majority if not all are Exynos variant users (not based in US).
Personally, this is definitely not a telco provider issue as I have had this issue on my old SIM (which was working fine on my old phone) and new SIM that I recently got after switching providers to see if the issue went away.
For me, sometimes the calls come in a few minutes late, and then the phone rings but when picking up, the call just gets stuck because the other party is no longer calling.
This is particularly noticeable as due to mostly staying home during COVID-19.
Toggling flight mode to "wake" the cellular network makes the phone be able to receive calls again.
Forum thread for reference: https://us.community.samsung.com/t5/Galaxy-S20/S20-Ultra-not-receiving-calls/td-p/1190155

Lucky me. Didn't have this problem on my s20+ exynos

I also have this issue (S20+ exynos, dual sim). I use wifi at home/work and I had several missed calls and delayed text messages during this time.
Now I turned on the text alerts about the missed calls. At least when my phone connects again to the network I get these notifications.

I am also having this issue. People call and it rings out at their end but not at my end. Is there any fix?

Try switching the active number to slot 2. I tried it for a couple of days and I think it was better. I have switched back to slot 1 to monitor as I just got the ATE6 update and wanna see if it changed anything.

I had this issue and figured out what was causing it. You need to disable VoLTE if you are not registered to use this service on your carrier's network.

My sim cards are already registered to use VoLTE, my carrier notified me a few months ago about it.
I tried to disable VoLTE on both sim cards. It was OK for 2 weeks until now.
I got a new missed call notification text message and after 5 minutes a message from the caller.
Now I enabled VoLTE again for one sim card. Let's see if there will be more missed calls with this setting.

Question Pixel 6 Pro Issues - still after Dec. update

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

Question NR only, NR/LTE

So when i dail #*#*4653*#*# and i change my preferred network to nr only, I cant call out the call ends right away. Also cant get phone calls, on the other side it rings and goes voice mail, but the caller says it rings. But when i switch back to nr/lte or and other network i can get calls and call out again. My last pixel 6 pro before it stopped working never done this, t-mobile sent me another pixel buts its refurbished. Any one ever have a pixel do this before?

Then change it
