Nexus 6p Can't make or receive calls

Hello Everyone,
Happy new year.
I recently received a nexus 6p model H1511 from ebay. everything works normally except sending and receiving calls.
I live in Qatar btw and I'm struggling to fix this issue. Anyone knows how to solve it?
Texting in and out works perfectly.
LTE data is working smoothly.
Only issue is making and receiving calls.
Appreciate your help
Thanks

Sounds like someone switched your radioband. You might ask how do you know this. Well I was playing with my phone yesterday and did just that. I had data and was able to send SMS but unable to make calls. I was able to fix this by reflashing my phone to stock and using dialer code *#*#4636#*#* go to "phone information" click the 3 dots in upper right and select "radio bands". I used band 6 so you might want to try band 8. Hope that solves your problem. Also please anyone who reads this DO NOT mess with the band settings it will screw up your phone. I am not responsible for any damage to your phone if anyone tries this. This is just how I fixed my phone and offer it at a suggestion to get this gentleman's phone working again.

I forgot to mention I flashed back to 6.0.0 if your not on a custom ROM try the dialer coded without flashing and see if that fixes your problem.

Just ignore the Verizon stuff, as you're not on verizon
Really hope it isn't a EFS/IMEI issue... if it is, the guy sold you a lemon (most likely)... repairing that without a backup is near impossible.

I just found another thread here on page 2 and they have the same answer. I didn't see it yesterday when I screwed my phone up.

(can't find the thread) but someone in a similar boat said they did a factory reset, and then re-installed the bootloader and it fixed their issue.
but Id try to find that thread and knwo EXACTLY what you're doing before going down that path

I tried restoring the radio and bootloader it did not work for me

Well, let's hope for this guy's sake, the seller didnt screw up the EFS/IMEI, leaving him w a data only phone.

I really appreciate your efforts .. I did return to the stock rom .. the original 6.0.0 and it did not help. when i try to dial any USSD, it gives me MMI error .. i dunno if it is related to EFS/IMEI as u said. Plus dialing *#*#4636#*#* , i find only USA band, Band 6 & 7 only ..
a friend of mine bought the same model from amazon and he has the same band when dialing the above code, he also have the same bands ( USA, 6, 7 ) like me and his phone is working fine here ..
What do you suggest? it's an EFS/IMEI issue ?
Thanks a lot. I really appreciate your concern. the problem is I can't return it ...

Did you select a band? Of you don't click one of the options it will not change.

I did choose usa band and nothing .. i feel it is a problem with the carrier recognizing the phone

I'm starting to lean towards this being an EFS/IMEI issue.
Research is all I can offer at that point... exhaust everything beforehand, because EFS issues are nearly impossible to repair, unless you have a backup, which you dont.

but the guy u shared me his link could solve it .. however he is ok verizon .. i believe it has something to do with my carrier ?
maybe the phone is not recognized right? but when i tell this to myself, i quickly come to a point if the carrier unable to recognize my IMEI right, would texts and LTE work ?
GSM is in service when i check phone information by *#*#4636#*#*
huawei technical support in Qatar would help if i gave them the fone ?

Try band 6 or 7 but I would lean towards band 7. I don't think your carrier name would show up if it were a bad EFS or IMEI.

Nailed it. Problem solved.
Installing Chroma ROM solved the issue because basically it was a problem of bands. Chroma had more bands that work in Qatar. and I could return back to stock rom again without any problems ( but don't mess up with bands in phone information )
I had to choose Aus band to make it work here in Qatar.
Band 6 and 7 and USA did not work for me. Chroma ROM had more bands that helped me to tangle this issue.
Thanks buddy @scoobysnack for helping me out.. I would solve it without your assist. I owe you a bag of marshmallow

No problem. It was my pleasure to help you. I told you installing chroma would fix your issues

Hi. Would you be able to walk me thru on installing Chroma? Same issue here. Calls work under 3G but if I choose preferred network type LTE(recommended), data and texts only work. Calls do not.Im from the Philippines btw.
I tried to access hidden test menu, radio bands available are only United States, Cellular 800, PCS and Class 10 (800Mhz Secondary)
Preferred Network type is LTE/CDMA/UMTS auto (PRL)

Can anyone enable volte feature in s4 gt-i9506

Developers i really need you help regarding volte
In india reliance jio(sim operator company) is giving free calls nd free data for 3 months(check on google about reliance jio for more information) but it has one problem that call will only go through voice over lte. Thus if you phone does not have volte so you cannot call from your phone. So i checked on inernet that volte can be enable by software update. Samsung gave software update to many phone like s7,s6,note6 etc but didnt updated s4 as they stop uodating this phone now. So now now only you all developers can help me. Plz tell me how to enable volte or is there any custom rom that has this support plz replt fast. Check on google for more information about volte.

Plz tell frnds

Yes ......but in i9505

Hey I asnwered to you multiple times. I am starting to think that you are too lazy to even google that thing. Google is full of answers to that. First try to search your problem by self, after when you can't find any solutions, then ask. Asking others to do your work for you is rude. Xda manual even says; search before you ask.
HERE IS JIO'S APP FOR IT:

You can call 4g/lte calls with your phone anytime. Just learn how to use your phone. And please hit thanks, when people help you

Bro listen i have this app this is called jio4gb voice which is given by jio to non volte customers. I forget to mention that i have this app. But this app is a severe headache. It consumes a huge amount of battery like you are continuously playing game. Also it lags nd heats alot the phone. And the majar problem is that this app continuously need data connection and that internet should be from jio4g and if i use wifi then this app will disconnect from server nd i cannot accept and make calls.That is why i need inbult function of this that will be in sim settings as then no data is needed for making and accepting calls. I will upload the screen shot as well of how it looks like in setting. External app is just waste. So in my view a new custom rom is the only way to enable as all the companies are giving new software update that supports volte but s4 is not getting new updates from samsung. So only you all developers can help

Bro, I asnwer to you just one more time: Rom developers can´t help you. That kind app dedinivolng is too big work. AND YOU CAN´T MAKE VOLTE CALLS WITHOUT 4G ON. THAT IS THE VOLTE FUNCTION. TRY TO UNDERSTAND THAT. ( VOLTE=VOICE OVER LTE). You can try ti install full s5 rom and see if there is the option. But still you have to keep 4G on!!!! But if you won´t use the Jio´s app that is stupid. you can put from your setting both wifi and 4g working at same time, so that they are on together all the time. Second option is call yo your servivise provider and ask them to give to you volte ip call settings and everything else from there. And now if you have anymore questions pm me!!! Do Not spam anymore. But first thing Call Your service prider ( jio) in this case. This is not so difficult. AND PRESS THE THANKS BUTTON, WHEN PEOPLE ARE HELPING YOU. That is least what you can do.

Best T Mobile firmware to root?

I just rooted on the t mobile U firmware and I have a few of the common issues. The video calling option isnt there. The wifi password wont save and a few other minor issues. I fixed the wifi password not staying. Now I just wanna salve this video calling issue. The option to turn it on isnt even in the settings. Im just wondering what the most stable set up you guys have seen. The U firmware. The U firmware flashing the cp from t mobile or just the straight t mobile firmware.

If you search for ROOT Samsung S7 Edge, you'll find the issue with the WiFi very quickly. You have to download an app, and change a setting within it to keep it saved. Video calling, never concerned with it.
http://forum.xda-developers.com/tmobile-s7-edge/how-to/guide-post-root-common-bugs-fixes-t3427600

Video calling is specific to the carrier's custom OS that they use for their phones. That is why you do not see it as an option in the U firmware. It isn't carrier branded. But if you are on tmo, then you should be able to download their video calling app and have it auto integrate into the U firmware for use as normal. Never used it on the S7, so haven't tried it. I did bake it into a few ROMs before that were tmo and it worked fine.

Refer to that link to get video calling working correctly. I am on the tmo U firmware and just tried video calling my wife and it worked as intended. Hope this helps you out. Oh, and just search for volte settings under the actual settings menu of the phone to insure that it is turned on.

I have volte turned on with the icon showing but when I place a call the HD icon does not show within the dialer. How do I know if it is working?

If the other persons carrier supports the function, then a green icon that looks like a camera will show up allowing you to tap it to send a request to the other person. If they accept the request then the video call and HD calling will commence. Now as far as regular old HD calling, once Volte is enabled, every call is considered an HD call as long as you are on an lte tower. Let me know if you have anymore questions.

As long as you are able to call, you're fine. I do not know what triggers the HD symbol, as it randomly came once for me, and has been coming since.

am also faced this problem ,,, seeking for fix .. if any one fixed that prob pls share with us ,, thanks in advance

Have you tested your Jio Sims in another device, making sure it's nothing to do with your SIM?

i recently taken JIo sim...i can not call anybody ..and nobody can call me ether....it says my number is switched off....though i can use internet ...i am on latest RR rom android N 7.1.2 from silesh nair... same issue was with the latest lineage os ......
same sim was working fine in lenovo k5 note plus with no issue.....

I am also facing same issue not able to call using jio sim because volte has been disappeared from the status bar. model-xt1643 running stock N with 1 march security patch.
Please anyone help me to fix this problem any solution.

Symbols doesnt matter at all. U can manually turn them on or off. Main issue remains whether u can use it or. As long as the problem goes, in updates it will be fix(mostly have been fix while im writing) if not try this.
Keep second sim card on stand by mode all preference to ur jio sim(make sure it is showing in setting>sim cards). For rr in configuration system tuner check volte and try again. checking volte is just to asure tht it is working other wise it doesn't matters.

Under system tuner VoLTE icon is enabled.

Reboot device, remove and re-insert jio sim and see if you get that enhanced 4g lte option in sim settings.
Volte symbol in status bar can be enabled/disabled in some roms it doesn't matter if you actually have volte service or not .
Device HD capable notification which used to appear on status bar when you enable 4g lte option won't come now on most roms...reason...

So guys you'll no longer see the `Device is HD Capable` Notification on any of the custom ROMs for athene as this new commit has been pushed to the muppets git (where all our vendor blobs are stored), so if you don't see the Device is HD Capable Notification, doesn't necessarily mean that VoLTE isn't working on your device.

Verizon WiFi phone call.

Anyone get this to work on Verizon? As soon as I insert Verizon sim, WiFi calling option goes away in settings, and phone app wants me to enable wifi calling while trying to make a call.

No luck here. Have you called Verizon? I did but my signal is too weak. This is probably going to be a deal breaker for me.

I'm just making do with GV for WiFi calls for now.

On the phone with Verizon and he is telling me that the Essential Phone requires Verizon's firmware in order to use any Advanced Calling features such as wifi calling...

You've stated this before, can you explain? From what I've read, wifi calling is not a feature of Google Voice. You can make calls with GV, but it is still using the carrier's signal and not wifi.

Yes, they said "We can't guaranty all services will work or not work on non-Verizon branded phones".
If you remove the sim and restart the phone, the WiFi calling option appears again in settings. Add the sim and it's gone. I guess the software has to let the sim dictate what options the carrier wishes to be enabled on each phone. That is what "verified" means?

I've managed to get VoLTE / advanced calling working for me... Took a few sim card activations but it eventually worked. As far as wifi calling, I can't seem to find the option or setting to enable it... Hopefully it'll be fixed once oreo is outta beta

You need the Verizon firmware to enable wifi calling and unless Verizon start selling this phone the firmware won't be available.

how did you pull that off exactly? whenever i enable it when i try to make a call i get service error

new sim, and took off hd calling of my account and then re-added it back to my account and rebooted. i also went into the 4363 testing menu and made sure volte was turned on. as well as the enhanced 4glte option was switched on.

maybe because Verizon sell the pixel and iPhone, they provide google and apple with the necessary files.

It sucks, I really wish WiFi calling would work. Maybe eventually it will, I remember when VoLTE was proprietary and now almost all phones support it.

How can you tell if it's working? I have the options in my menu but since my signal is good it never switches.....
I went to hell and back trying to get OB 8.1 to work with my Verizon sim OB3 and down work without issue.
Anyway I wound up getting a new sim card from Verizon then went back to OB3 did the OTA and when it booted back up I had to do the prl update *228 once I finished the steps I noticed I had wifi calling enabled in all my menus it didn't ask for an e911 address on my phone but it did on my wear24 watch which is synced to my phone and number. the watch can do wifi calling and texting as well. Hell of a deal for under 70 bucks. Not sure if that triggered something on the phone?
