Possible phone use on Verizon 7.7

Let me note: I am not a dev nor programmer.
With the similiarities of the P6800 and the Verizon 7.7, I threw together a rom w/ stock SCH-I815 samsung/verizon kernel using the P6800 frameworks and apps into the Verizon 7.7 and removed most bloat. The LTE/Verizon antennas aren't recognized by the device at all but everything else was working.
Now, you can't swap the phone.apk's around without the framework's else you'll experience FCs. So obviously I'll need to use the base stock apps and frameworks and go through the 2 framework files hunting about.
Has anyone else with the Verizon 7.7 taken a look into this?

I'm curious if you've made any progress on this?

Not yet, probably be a week before I even look through the files again. But I believe it's fully possible to get phone use

i think you will need to find samsung modem for verzon networks, does verizon have a galaxy note or sgs2?
although your modem firmware probably has voice disabled, may have to find modem manufacturer and try to flash custom firmware.
good luck, wish you the best.

I'm happy enough using GrooveIP for google voice calling. What I'd really like is if we could activate the phone profile in bluetooth (or will that just come with enabling the proper phone part in the 7.7?).
As of now i can use GrooveIP and bluetooth to listen and speak, but it won't let the bluetooth device answer/hang up/transfer address book/show caller ID (on the Verizon LTE 7.7)

Doesn't verizon require some sort of signed telephony to work properly on their network

I got no idea but with the other packs it didn't detect the radio at all. This is keeping the vzw radio partition stock. I like the ideas and really wish the note was verizon as that'd help figure things out.

It does for LTE but cdma service doesn't use sim

Seeing as your data account won't have any provisioning for voice usage, even if you DID get a working modem and a modified framework to allow for phone functionality on the device, I doubt that you'd actually be able to made or receive a phone call due to Verizon's limitations at the account and provisioning level anyway.
Point is, it's a CDMA device, and thus your service is attached to the device itself, not the SIM card (except for LTE data). Basically, you can't just provision service to the SIM card alone, and then simply swap it into a different device. So if you got the modem and the framework working, and you called in to Verizon customer service and asked to provision your line for voice, they'll just be like "Umm, no... We never INTENDED for you to use that device as a phone, so no... You want a phone? Buy a phone. You want a tablet? Buy a tablet. You want to do both in one device? We won't allow that because that loses us money that we would be getting by having you either subscribe to two lines, or charge you extra to tether..."
There is a much simpler solution however.
Ditch ANY CDMA carrier in favour of a GSM carrier instead, preferably one that uses the same compatible frequencies adopted by the rest of the world, like AT&T (and MVNO's based off of AT&T's network), and buy the P6800.
The moral of this story is this: if you want the latest devices, with the best features, you're NOT going to find them in the north American market, EVER, at all, period; you're just going to find watered-down, gimped, bloated, and locked-down versions of the international models. You HAVE to import. If you're going to import, you HAVE to use a GSM service provider... That's just the way it is. It sucks, I know, but it is what it is.

I would have to agree, the GSM version would be best. It would be near impossible to make this happen. Of course if I was stick with one, I would try everything I could as well. I'd probably fail miserably and go for something like GrooveIP.

I move my SIM between devices all the time and have never needed to call VZ to provision the new device. Voice and data just work.

I can CONFIRM the following:
I have a VZ tab 7.7 with 5GB data plan and I have a VZ Razr with voice/unlimited data plan.
Both are LTE devices and hence use (micro) SIM cards. In "My Verizon" even the tab has a phone number assigned to it's "line". A call to that number just rings but obviously nothing on the tab.
BUT...
Put the tab sim in the phone and YES it will ring if you call that number! Even TXT in/out works! I assume they will just charge me per txt and per min phone use BUT IT WORKS in a PHONE.
And the kicker is, the unlimited PHONE SIM also works in the TAB! I immediately get LTE data and can surf with the tab. Of course at that point calls and texts to that phone number are "ignored" by the tab's neutered modem.
Lesson learned:
IF there was a way to flash a modem, say for example from the Samsung Galaxy Nexus to the VZ 7.7 TAB, we would have a full supersized phone in our hand. Only downside, no earpiece. So only speakerphone or BT calls I guess.
Anyway, after a little more research I also found this very interesting article:
http://www.phonenews.com/verizon-affirms-unlimited-smartphone-sim-card-usage-in-hotspots-tablets-lte-ipad-20053/
Hope this helps bring a little light into the messy CDMA/LTE darkness

I have swapped my Galaxy Nexus SIM in my VZW LTE 7.7 numerous times. It works. I'd love to have voice on the VZW LTE 7.7, then I could possibly do it all on my tab. I'm no developer tho ;p

Verizon WiFi Calling inside Advanced Calling 2.0&/or T-mobile Volte work w/ Nexus 6

Verizon WiFi Calling inside Advanced Calling 2.0&/or T-mobile Volte work w/ Nexus 6
inquiring minds want to know.......................................

My understanding is the the only way Wifi calling works on Verizon is to download and use the Verizon Messages+ app. Pretty lame but I think that is the current state of things. I would love to be wrong on this.
Some links that talk about it:
http://www.zdnet.com/article/lagging-its-peers-verizon-adds-wi-fi-calling-but-theres-a-catch/
http://www.spotonnetworks.com/verizon-enables-wifi-calling-with-a-few-caveats/
http://www.inquisitr.com/2577556/verizon-wireless-finally-offers-wi-fi-calling/

I find a lot of reports that folks are using Verizon Messages for wi-fi calls on the N6P. That's actually not that bad of a concept.
I'll have to try it when I get some time. I can't find any kind of definitive guide to making it work, but it seems possible, at least for MAKING calls. Unless I'm misreading all of this stuff.
You additionally have to go online and enable Advanced Calling 1.0 on your account (the same Advanced Calling that lets you do voice and data at the same time) -- I think that without this turned on, you can't do Wi-Fi calling at all either.

No VOLTE and no WiFi calling T-Mobile, what gives?

I'm gonna make a post here since NOTHING seems to be working. I'm a T-Mobile customer. Yesterday, I purchased a great condition nexus 6P from someone because my LG G5 is cracked and I was getting tired of it anyway so I opted to just buy a nexus instead of using my insurance on that phone. Everything is all good except for one major issue. VOLTE and WiFi calling just refuse to work with my sim in the Nexus.
I've called T-Mobile twice. I've factory reset from back up and reset settings twice. I've hard reset from stock recovery once. I've wiped network settings and restored default apns. I've manually changed the apns from what I see on Google, reddit and here. I've copied my apns from my LG G5 where VOLTE and wifi calling work perfectly fine. I've cleared cache. I've cleared the cache of the project fi and hangouts apps just in case there's something left over from the previous owner. I've gone into the *#*#4636 menu and tried a bunch of different stuff several times but no matter what I absolutely can not get wifi calling or VOLTE to work with TMobile on my nexus 6P. LTE it's self works perfectly fine for data.
Yes, all settings for wifi calling and enhanced LTE calling and VOLTE are turned on lol. I've tried the trick where you toggle wifi preferred on and off and restart the phone. Nothing happens. I don't even get a wifi calling reg error. It never shows as active in the data toggle in the quick settings are nor the status bar or dialer. It just isn't active. Same for VOLTE. I AM getting band 12. I can see it in the LTE discovery app. VOLTE just isn't working though. Whenever I make a call I can see LTE switching off and it switches to HSPA therefore making calls really difficult in my shoddy signal area at my house which is why I really need it to work.
I'm fairly certain I can root and install a ROM which will fix these problems but I don't own a PC. . I thought MAYBE the previous owner had previously had the phone rooted and tinkered with something somewhere that may have messed something up but that doesn't appear to be the case. Bootloader is locked and recovery is stock.
Can anybody help and tell me what in the world is going on here? I don't want to have to sell this nexus and revert back to my cracked screen G5. I would just switch carriers but I still owe money on the G5 so I was just gonna ride it out til I payed it off.
O and one last thing, after scowling google and forums for hours on end yesterday and today I did see one post mentioning something about this stuff being related to IMS provisioning and settings which are tied to a phones IMEI on T-Mobile and not the sim card and how that person simply called T-Mobile and got a hold of wifi calling technical support who was clueless but created a ticket for him and within 72 hours the issue was resolved. OK well I did the same exact thing and they refuse to create a ticket for me because it's not a T-Mobile phone and because according to them they are not allowed to create a ticket because wifi calling works fine in my G5 and therefore it's the phone and not them or their network lol. What a crock. I'm willing to bet if I put the sim in another unlocked phone with 7.1.1 and wifi calling fully available that it isn't going to work either. There's some sort of communication error going on between the sim being in this phone and their network it appears.
Check these screenshots out. T-Mobile is clueless

I can only suggest;
1) Find a PC and re-flash the latest factory images from Google. Both "fastboot flashing unlock" and "fastboot flashing lock" will wipe all data, so backup first. Also confirm it fully boots correctly after flashing before you re-lock the bootloader.
2) Get a new 3-in-1 SIMM from T-Mobile. You can use their web site to switch cards and give it 24 hours to be fully provisioned.
3) Confirm your E911 address is correct on T-Mobile's site and wait 24 hours after any changes for Wi-Fi calling to actually start working.

I HAVE THE SAME EXACT PROBLEM AS YOU POSTED!!! GONE THRU THE SAME PAIN. LOL I'll attempt the ticket thing to see if I get anywhere. Did you ever get it resolved?
EDIT:
My theory is that since the phone was used in Project FI, they specifically turn off this feature in the back end for the specific phones, by Imei or something since project FI uses T-Mobile as well.
EDIT 2:
they wont' create a ticket for me either. I guess I will just have to ride it out.
EDIT 3: I FIXED IT!! NEXUS 6P VOLTE AND WI-FI CALLING FIX T-MOBILE
I flashed back to android 6.0 Build#: MMB29N (I used the Nexus ToolKit 2.1.9: google it. BTW, your phone will be wiped, so backup first) VOLTE just started working with this version of android 6.0. Then I upgraded using the OTAs and now i'm on 7.1.1 build#: N4F260 with VOLTE and Wifi calling working as it should! I hope this helps someone out there!

For what it's worth, reverting to the build you mentioned fixed it for me on my two Nexus phones coming from Project Fi to T-Mobile as well! Thanks for the help!

You only need to install the radio from build MMB29N. I did this by downloading the build from the android website. Extract the radio from the zip and install it (I used nexus root toolkit but you can also just use flashboot if you wanted). This means you don't even need to revert your image and lose your data.

wish I had seen this sooner. cheers!

Had the exact same issue and this fix worked for me. Wasted a couple of hours with T-mobile (they were actually very helpful and debugged everything on their end to confirm the provisioning was good) and then 2+ hours with Google support. Actually had already filed for a device replacement which I canceled after finding this post.

I'm so glad I found this thread - my VoLTE and WiFi calling has not been working on T-Mobile and I'm anxious to give this a try. Numerous phone calls and support tickets with T-Mobile haven't resolved the issue. I don't know much other than how to follow detailed directions. My phone isn't rooted and bootloader is locked. I'm on Android version 7.1.2. Is there a way for me to install the MMB29N radio on my Nexus 6P without losing my app data given that my bootloader is locked?

Flashing the radio -sadly- requires an unlocked bootloader.

Did you resolve your problem?
In android 7.1.2 did you notice in Set preferred network type is set at " LTE/GSM/CDMA auto (PRL) "? 7.1.2 has been giving me issues with sms/mms. I noticed Android 6.0 has this set to correct T-mobile bands.

All works for me in 7.1.2. Make sure you don't download the Verizon version of the stock ROM. That was my issue why I couldn't have volte and Wi-Fi calling

T-Mobile/Oreo Roms

Any Oreo ROM I've tried recently I can't get volte/WiFi calling to work to activate. I'm using metro PCS and the trick on nougat ROMs to get it to work properly every time is to just delete the metro APN and use the T-Mobile one. Why this works, idk. I know it CAN work on Oreo ROMs because it did in earlier builds but I've abandoned all hope because it just won't work anymore.
Unfortunately at home I have little to no edge/3G for calling so I rely on volte/WiFi. I don't make much calls anyway so it's not too important but I'm wondering if anybody has a clue what the issue is? I'd like to be back on Oreo with all the progress that's been made.

Does unlocked essential phone work with Sprint Wi-Fi calling

There is a Wi-Fi calling check box, but nothing seems to happen if I check it, and it doesn't seem like the essential APKs are there to make it work. Does anyone know if there is a way to make it work?
Also, is there a surefire way to test if it is working -- ex. should true WiFi calling work in airplane mode with WiFi turned on?
If it's unsupported on the unlocked device, is it known if it's possible to flash the Sprint rom to enable the feature?

It works perfectly well on my unlocked device in the UK. It does depend on your carrier, though, as to the support they provide and their requirements.

I have an unlocked PH1 on Sprint right now. Wifi calling works perfectly. If you are using a custom ROM, you will typically need to modify build.prop to add in support, but it does work. You may need to flash back to complete stock to go through the Sprint setup. This is done to update PRL and other odd files Sprint uses. Can't update those on a custom ROM. You can confirm if it is working or not by looking for the highlighted icon.

When I first put my Essential on Sprint, I could not activate Wifi calling, Went in to "About Phone", "OMADM updates" and updated PRL and Profile, that was no help.
I called support twice, and couldn't get it to work. It wouldn't let me turn on wifi calling.
I went back to it 2 weeks later, and it is now working perfectly. I work in pretty much a basement with no Sprint signal, but get Wifi calls just fine now.

That's very helpful. So you didn't complete any sort of Sprint related setup with the Sprint logo on it, right?
