Hey all, I've Googled this all afternoon and I can't find a good, or even an answer, really. I've been having a few issues with my 6P dropping cell connection. I'm trying different radios (anyone use the Huawei engineering radio?), and the phone currently runs Lineage OS 14.1, just flashed the May 8 nightly. Also running the current Franco kernel and latest TWRP. My carrier is Project Fi (which I love, even in a rural area). I love the phone and had had zero problems until I updated to the latest radio (3.81) a week or so ago and then I started getting random dropped connections. I was on Pure Nexus then and since switched to Lineage primarily for the consistent updates, but when it's connected the service is the same on both ROMs.
That brings me to my question. I'm in the Info Menu looking at various settings and I notice that the phone number listed there isn't mine. In fact it's an area code in a different state. My question is if this is a Fi thing or if it might be the cause of my connection problems (and how does that number get changed in the first place? I haven't been diving very deep on this phone). The phone was an RMA and has a build date of Nov '16, wasn't activated before. I recently moved from Ting to Fi, can't imagine that's the issue. Anyway, anyone else have this problem, if it is a problem? I've never seen a different number in that menu, so I'm curious.
Also, anyone else having problems with the 3.81 radio, or use the Huawei engineering radio?
Have you factory reset with stock software? Maybe Fi is trying to do something with the carrier switching. I've been trying to find the engineering radio for a while,. But all links I find are outdated and no longer work.

I'm thinking it's a problem with Lineage as I had zero issues on stock or on Pure. I have an engineering radio image but no idea how old it is, though if it fixes the problem old is fine.
Care to share that engineering radio?

I've been having that issue with all the roms I've been trying. Once I lose lte I lose it for good. I have to stick to roms that have the option to change apns or I won't b able to use data at all

This is a Google Fi thing and is normal. The number is likely T-Mobile, although you should actually have 3 (one for each carrier). Google Fi works like Google Voice and forwards calls to these temp numbers. As for the radio, I would downgrade to 3.72 as this is a known issue on T-Mobile.

I wanted to share a problem I encountered & worked around when flashing custom ROMs. The loss of mobile carrier settings & inability to restore without taking it to my service provider.
Yes, I have read through this forum & other forums extensively to find a amenable solution to no avail.
Possible solutions found were tried to possible extents/applicability but did not work for me: I've done Nandroids & restores, I've used TB to back-up the specific mobile settings & restored, I have looked into an elusive EFS folder (which seems like is GSM specific), I have manually wrote my phone's identity, hardware & software info in the hopes of manually reinputting/restoring (which I have yet to find the app, software or EPST code that allows me to do this...except maybe the cdma workshop which I cannot justify purchasing nor am I willing to "acquire").
This happened two times; once after flashing an AOSP ROM and another time when I updated the PRL.
After flashing the AOSP ROM: after an entire weekend of no phone/data service (wifi worked, cell was otherwise functional) and researching...I took it to my service provider. The technician was unable to execute the EPST codes which was apparently related to restoring the phone to their network. It took multiple technicians and 3.5 hours for them to restore it.
After updating my PRL (by this time, I had switched to a sense-based ROM). I took the phone in the next day & the same technician restored it in less than an hour. Also, the PRL was "downgraded" or reverted to the original PRL.
I have since flashed 2 other sense-based ROMs and have not lost these settings. Otherwise, my Radio, WiMAX, PRI, NV & HBoot versions are all up to date. My PRL apparently can't change for it to work with my provider.
I know it's noobish & lame...but this is my workaround...for now; I only flash sense-based ROMs.
I really liked that AOSP ROM.
Constructive comments appreciated & thanks for reading.
I had something similar occur with my phones. I had trouble first activating a rooted EVO 4G only to find out that the programming menu, EPST settings, had mysteriously disappeared. After searching all over, I found out if I updated the all the radios, combo zip, that it restored the EPST settings and was then able to access the programming menu. Mind you, I had to do all this while chatting with sprint rep trying to activate it.
Once it was activated, it was working fine, then soon after I found out that the 3G connection had stopped working. Now this I found out to be fixed by updating the profile. Because the 3G was down, I had to connect to my wireless router in order to have connectivity. This solved the dropped 3G data connectivity.
But in trying to fix the data, I had since flashed to another ROM to make sure that the data was not broken due to a ROM. I found out that once flashed to another ROM after updating the profile, that NOW I had lost voice. It was as if it had been deactivated. I then went back into the EPST settings and saw that it reverted back to the old user's phone number (MDN) and the MEIN(?, the other number used to activate) was also changed. I was lucky to remembered the latter number because it was only one digit off. So seeing that these were changed, I changed them back, and this restored my voice connection.
This is the first time that I have ever experienced this type of problem with a rooted HTC EVO 4G and I have had this phone since the beginning.
Hope this helped a little. I actually just posted something about this yesterday.

I did not do the updates until after I had my cell restored and then flashed a sense-based ROM. Now, all is updated & in my experience since...radios, PRI, Wimax etc...continue to stay current when I flash a new ROM. For some reason, I don't have to reflash these (I've read some people have/have to).
Because the 3G was down, I had to connect to my wireless router in order to have connectivity. This solved the dropped 3G data connectivity.

I verified these numbers were all the same prior to and after I had updated the PRL and after the techs restored it. The numbers were all the same with the exception of the PRL.

I actually read your post prior to posting this...but my impression of it at the time was that the change in phone number was the determining variable.
Much thanks for your supportive comments.
I have an ntelos S5 (G900R7). There is no development for this phone anywhere on the internet. Perhaps I can find support here?
---------
So far (you may skip this part):
I have managed to successfully install Spirit Rom with full functionality, by copying my old build.prop into the system directory, and restoring my previous apn settings using the apnsbu. I forget why I left this rom, but I did. Everything I try has some problem! I then proceeded to try just CM11, by itself, and had 3g difficulties. Then, using Kushman's sprint MIUI, (Ntelos shares sprint towers) things seemed to work right, but it remapped my recent app key to menu... (perhaps I can map it back?) and the volume was not controlled by my physical volume buttons.
-----------
Now my favorite rom so far: Mokee Rom It's fast and visually pleasing, but I have wi-fi and phone difficulties.
After imposing my APN settings, I can reproduce these effects:
(1) Before replacing build.prop, the wi-fi works and can be enabled or disabled as I need. Also, 3g works very well at nice speeds, but it says "Verizon Wireless" underneath the 3g indicator bars. However, I cannot make calls. If I attempt to do so, the 3g data stops working, turns orange, and no longer says "3g". If I do this, then no data can be transmitted or received.
(2) After Replacing build.prop with the "good original" copy (which sometimes fixes similar problems in other custom roms) the wi-fi becomes stuck in a constant state of "turning wi-fi on..." but never turns on. 3g still works, but, as in part (1), it will break if I try to make a call.'' Also, in this case it says "Sprint" instead of "Verizon Wireless"
Does any one have advice, or perhaps some build.prop settings to modify? Or maybe there's a different file that would help. Again, my phone is the SM G900R7. Has someone else with this phone had luck customizing it?
Thank you
nTelos S5
Likewise have a nTelos S5, have not found any custom roms that can successfully be installed without data or phone issues.
Also trying to install any ASOP roms resulted with all phone efs data getting cleared.
Upon searched relentlessly the only rom I found that functions is located at
http://teamcspire.com/index.php?/topic/112-gs5-g900r7-r2-teamcspire-nd8stock-deodexed-101814/
its very stock but functions flawlessly for me.
Advise if you have any luck, I will reciprocate.

My advice is to you, is that if you install Mokee rom, do not update it with OTA update. This is what I think broke the network for me. Even after restoring my phone to factory conditions and using Kies, I still had no network. I ended up going to the nTelos store, where they had to reset the network service for my phone on their end... strange.
Anyway, I have made a few roms work, and I suspect I could make more. If you maintain your apn settings, and build.prop, you should be able to make Spirit rom work. The same thing is true for Miui. However, if I remember from my experience correctly, if you do install Miui, then I THINK you should not restore your original build.prop; it may work without it... just restore the apn settings. When you do this, you may have to change the preferred network mode... I am a little freaked out, after my previous experience with Mokee rom, to mess with this any longer, though. I do have a problem with Spirit rom: if I use the Timely alarm clock, the time panel is miscolored, but I believe that could possibly? be fixed by flashing a different kernel. I plan on flashing Spirit tonight.... stock uses up my battery too fast, and Spirit just feels more responsive.
EDIT: I just re-flashed Spirit Rom, and they fixed the discoloration in the most recent version! Also, as before, my 3g and WiFi work fine.
Took me days...
The CSpire shares the model number and ROM. The US Cellular CM11 is the closest. Somewhere in that I lost my ability to send texts (not sure if it's the SMSC or...) and didn't get it back when I ODIN'd to stock. I would LOVE to have CM support for this model.
I also am in the same boat as you guys. I would love to get another reliable ROM on this phone. I just have bad memories of purchasing my last one (Sprint GS3) from ebay, and having one hell of a time making the MMS work after flashing it for nTelos. However, I never did have to mess with any of the APNs or build.prop settings on that one. I would think the Sprint ROMs should be the closest compatible ROM, being that nTelos and Sprint do share towers in WVa and Va (Sprint actually has zero towers in these states, and leases nTelos towers instead).
Is using EFS Backup by Wanam a good method to insure the EFS does not get screwed up?

You might try saving out your wpa_supplicant file from the stock ROM and replacing it on the flashed ROM. This has worked for me before on my GS3. That might take care of the wifi anyway.
I'm also on ntelos with the s5 now. But it is a us cellular unlocked by them phone. Stuck in a ntelos sim card that I bought from store and everything works. Except 4g. I can live w/o it but it's kinda like a puzzle now. How could I enable this to work on ntelos?
Depending on where you are, ntelos does not have 4G in many places yet. It's still very spotty in West Virginia.
Has anyone taken the OTA Lollipop update? If so, how is it working and does it lock or put in a new bootloader?
I have. It's a little laggy at times, gets really hot when using it while charging and battery drains a little faster. Not sure about the bootloader

I think I will hold off for a while. My stock NK1 is laggy enough as is. Damn, I wish there was a compatible ASOP ROM available for this phone.
Honestly, this Samsung G5 is the absolute worst phone I have ever owned! I would like to get a S6, but my experience has been so bad with this S5, I am almost afraid to stick with Samsung. However, my S3 was awesome!
Just found out that the heart rate sensor is active when the phone is on no matter if S Health is open or not.
I am in the Richmond area on Ntelos. They have stated they have sold their bandwidth to T-Mobile and we are to find another carrier. My phone is not even a year old and no other carrier will activate it. Being I own mine outright and paid close to $600, I am about to lose my mind knowing that I will have a shiny expensive very small tablet in a few months. Has anyone a clue how to change this phone over to GSM or something useful. Verizon refused to even try, though I know when I tried Straight Talk's Verizon Sim it did dial to Verizon's customer service. But Straight Talk nor Verizon would activate it.
Ideas and suggestions welcome.

page plus,i am an ntelos dealer and pageplus dealer i flash phones to and from both companies everyday i am in ruckersville va 12 mile north of charlottesville lemme know if you need help you right its the enitre eastern side of the companyh is gone now to tmobile but you can still activate on frawg..ive done many for customers
Thanks for the info. I am on the frawg side of things now. Their plans were too much when mine ended and I didn't need a phone at the time. Then a few years later, yeah I made my S1 last almost 4 years, I bought the S5 late last year outright. Loved the S1. Made that do everything it just did everything slow at the end.
Anyway, am glad there are options of some sort. Have been reading the reviews of pageplus. What kind of speeds are you getting on it with 4G? Their map shows coverage everywhere which makes me a bit uneasy, as in too good to be true. Is it a simple flash or require editing?
If I can't do something else with the phone, I may try the band opening options. According to the phone specs, it should already have all the Verizon bands but they refuse to activate it due to the meid it seems. I have a feeling this topic may get more viewers as the Ntelos off switch day comes closer.
Google Fit was the culprit for the heart rate sensor staying on. Un-installed it and fixed it
After all this time, has anybody found a ROM that works well on this phone?
can't get data so Internet not working on galaxy s5 unlocked already switched ntelos

In case nobody has seen this, there is a now a CyanogenMod 5.1.1 ROM available now for nTelos. I have been running it for 3 days now and I really like it. Good battery life too. Very stable and very speedy. There are some occasional bluetooth audio stuttering issues, but nothing terrible.

I have been entering the sprint code every couple hrs to get my calls to work. Project Fi support has no idea why or what is going on. The had me run a bug report. Hopefully that will get this resolved. Any one else on Project Fi having this issue?
Jayson
Still waiting to hear back from Project Fi team. I just spoke with the Nexus support team and was told there is no going back to 6.0 from 6.0.1. The tech I spoke with said that they have logged 7 calls with the same issue me. Mine now makes it 8.
Even though I am a bit frustrated with this issue Google support folks are 1000 times more knowledgeable and easier to work with than Verizon. This company gets how to treat and deal with customers.
Still not working yet. Google is going to give me credit for the inconvenience but I am beginning to lose faith in them getting this resolved. Switches back to T-Mobile and I keep missing calls. Uhhhhg. I really want to stay with Project Fi but I may be forced to look elsewhere for cellular service.
Have you tried *#*#34963#*#* ?
I had a similiar issue to you.
Where I live and where I work I get a stronger signal from Sprint than T-mobile.
After I updated my phone to 6.0.1 I had problems connecting to Sprint's network.
I used the "FI XME" dialer code and that seemed to fix my issue:
*#*#34963#*#*
I found a post in the Nexus 6 forums with the Project Fi dialer codes:

Ah yes then that's a problem, the Google update to 6.0.1 has caused all kinds of radio problems so let's hope they fix it quickly.
My issue seems a different. The Data and texting works fine on WiFI only, Sprint and T-Mobile. The issue is calling in and out on T-Mobile. Instant failure.
I'm having the same problem but I think it only happens when the phone connects to band 12 LTE on T-mobile. It seems that VoLTE isn't working properly. Can you check what T-mobile band you are on using this app:

Be careful! I did this on my last 6P and it completely messed up my radio and prevented me from making calls on Sprint (no it wasn't because of the SIM card as I tried 3 of them) . I had to RMA my device. My advice is not to mess with that menu. I have done it on other devices without issue but it seems as though once selected it cannot be undone.
I just found out yesterday that the engineers have not even looked at my bug reports yet. They were sent to them yesterday from what I was told. They also had me order a new sim card as well to rule that out. The support or lack there of up to yesterday has be ridiculously unacceptable. I get the feeling that they are just trying to pacify me and not doing anything in hopes that a new release will come out an magically fix this issue. Very frustrating.
Problem Fixed. After dealing with this for several days I asked a supervisor how long was acceptable to leave a customer with an open issue affecting cellular service and to be missing calls. He provided me a RMA and a new phone was sent. All seems to be work with the New replacement phone they sent.

Yes be very careful in that menu. I was just looking at the menu and my finger some how hit a different band. Took me about 4 hours to figure out how to fix it. There are some tuts here on that issue that will help. Also there's a way to get the international bands to show up
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.

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
I originally posted this post last week but I'm now wondering if there isn't anything actually wrong with my phone and maybe it's just locked by Verizon. So how do I tell if my phone is either
locked by Verizon
the radio is faulty or the files driving it are wrong
As I said I think it could be the former. The VS995 was only meant for the US market, Verizon in particular. But it worked fine in the UK under stock and subsequently AlphaOmega ROM. But when I flashed back to stock it stopped picking up a signal and though I've now had a major update to Oreo it's still not receiving a network. I've set the APNs of 2 different networks to no avail.
