Noob. LG V40. Advanced Calling Greyed Out. Exhausted Search - LG V40 Questions & Answers

Hello. I've tried so many search terms. Thank you for anyone who reads this and accepts me into the clan of knowledge. I have been using Page Plus Cellular with an iPhone and could talk and data at the same time. I hate Apple and decided to move into an LG V40thin. I absolutely love it. Page Plus Cellular is an MNVO on Verizons towers. The LG has no Verizon software so I assume this is some kind of universal firmware. For whatever reason I cannot talk and data at the same time. This phone is supposed to support VoLTE but when I go into the Advanced Calling section, it says "HD Voice" which is Verizons branding for VoLTE. The Advanced Calling option is completely greyed out. I also had received a text from PPC saying my phone doesn't support VoLTE and I may have issues receiving calls if I didn't upgrade.
Is there anyway to find out what is really going on? I only found one single search result that seemed to say an LG V40 that there were two models, one for Sprint and one for Verizon and if you had the Sprint, then unlocked it, it would work on Verizon but not fully since the hardware wasn't all there since Sprint uses different frequencies (radios).
I have no idea how to tell the origins of the phone, model, firmware etc. I bought it used. If the hardware is just not what is needed for Verizon, I don't know how I would look for one that was. The LG V40 is amazing. Top notch. The other cool thing about it is with the Verizon Note 3, when i tethered I got a message that I didn't subscribe to tethering and had to use PDAnet. With this phone, tethering just works.
Help. I appreciate it.

Please provide your model number found in Settings then in about phone.

I don't know I never have tried to talk and text at the same time. If it is a V405UA, you can unlock the bootloader and then install either V405UA or V405QA firware with LGUP. Hope this helps.:good:

Not sure if this helps, but: https://www.reddit.com/r/lgv40/comments/eqymrm/lmv405ua_on_verizon_whats_the_deal_with_cdma/
Where did you get the V40? I am not sure about one post on the models, because I have a V40 bought from Verizon and it's a LM-V405UA.

I'm thinking about buying the V405UAB. Right now though I can hotspot without Verizon telling me I have to pay for it. If I got the UAB, is there a universal image like I have now that could be installed safely? Who makes the images and is it safe? It seems like it would be easy to sneak in big brother code to steal your information. I'm very new to modifications so please don't take offense. Hoping someone has the knowledge to point me to an image and knows its safe.

I have Sprint. Which Note 8 to buy? Root. Please Help!

Hello,
Which Note 8 should I buy?
International Version
Unlocked Version
Sprint Version
I heard the processor for the International Version is best I think it stats with an E. Should I get that?
I would like to root.
Does it matter or should I just order one directly from Sprint?
Will this work with Sprint?
Samsung Galaxy Note 8 Factory Unlocked Phone - 6.3" Screen - 64GB - Midnight Black (U.S. Warranty)
This one from Amazon?
Should I buy that one above from Amazon or buy it directly from Sprint?
Can I root both of them?
I would like to order one today, I just don't know if I should order from Sprint or Amazon.
P.S.
Also if this is not possible should I get a S8 or S8 Plus? However, reading over on their threads doesn't look like root is possible really there either, hit or miss. Is that true? Which S8 I should get? International or US?
I mainly want apps like:
Ad Block
YouTube Background Player
YouTube Ad Block
ETC...
Please Advise.
you said sprint, sprint is cmda... meaning, exynos WILL NOT WORK. no international phone, you must buy snapdragon. now you have two choices carrier locked, and carrier unlocked. both have a locked boot loader and are not currently capable of root. if you purchase the phone out right it does not really matter which version you get. if you buy sprint locked after 50 days on their network they will carrier unlock the phone. the only true difference is carrier bloatware/ software which I'm hearing can be flashed using odin

Thank you, that is what I need to know. Now what about getting a S8 or S8 Plus instead? Are those rootable? I mean does it even matter any more? The only thing I really want root for is Youtube Ad Block, but what the crap, mine as well just pay 10 bucks a month and get Youtube Red and allow my phone to update it self all the time.

What about S8 or S8 Plus? Root those or are people still having trouble? I think Samsung has finally figured out how to make it really difficult. Seems like it is not even worth it anymore.

from what I hear it is possible to root the s8, but it limits your max battery charge to 80%? kinda a **** trade off if you ask me.
so I'm like you I thought I must have root, my last android was a Nexus with a completely unlocked boot loader and I flashed custom roms when I tired of my current rom. that was four years ago and I've been jailbroke iOS since. do you still need root?
most people will say no. if they say absolutely the main arguments I've heard are for xposed(which doesn't even work on android 7) and viper4android (or some similar name, a sound tweak I think) besides those two, removing bloatware, and hosts file ad blocking.
my personal experience: I will be giving up an unlocked boot loader by purchasing the note 8. this mean no custom roms. I haven't given up hope for a future possible root method, but I am willing to accept that it may never come or when it does we can only charge to 80% or something else ridiculous. I don't need root, I would like it, but I will compromise.
tldr;probably not, especially if you are willing to sub to YouTube red for 10$ a month.

The issue is that the Snapdragons have locked bootloaders but you need a SD version to use the Sprint network. It doesn't matter if you buy a Note 8 or an S8, the issue with the locked bootloader is the same.
For me personally, I need root because a lot of the apps I have use root. If you only wanted to block ads on YouTube, it's probably unnecessary and far more hassle than it's worth.

Last question. I saw on another thread that this ... Is this true? Should I buy one that is unlocked from Amazon or the Samsung site and get hotspot or can I get hotspot on the Sprint one or do I need to search for the perfect app to do it? Which would be easier?
Unlocked version:
Hotspot - Awesome
Download Booster - Awesome
No Bloat - Awesome
Wi-Fi Calling - working awesomely
Sprint Version:
LTE Calling - I might miss, might be worth flashing Sprint mod when available...

Sorry, I can't provide any guidance in this area. I'm in Australia and don't have experience with the inclusions/exclusions on specific American networks such as Sprint. I do know they use CDMA technology, which the Exynos SoC doesn't support.
Hopefully, one of the other enlightened souls on this forum can help you with this question.

The Sprint Version will cut out the download booster and hot spot unless your plan includes it but include calling plus features which include their version of the Wi-Fi Calling and LTE Calling for surfing over calls....but we already have that with Wi-Fi calling...Sprint also has Bloat software such as VVM but I install Google Voice for voicmail...it is up to you...at this point I have found no function lost.
Oops...I forgot to mention that they may update more frequently or sooner

That is extremely important. Do I have this right? If I buy the unlocked version. Can I surf the internet while on the phone with the unlocked version from Amazon or Samsung or do I need to buy the Spring Version?

When I called my wife on Wi-Fi Calling i was able to surf the web as well...I'll double check tomorrow when she is awake though
I have the unlocked version arriving soon and I will be using it with sprint. (With the free 1 year promo)
AFIK only the sprint and unlocked versions are whitelisted to work on sprint. Any other snapdragon models you will need to request a manual request to add your IMEI to the sprint database.
And I believe the Exynos models isn't compatible with CDMA at all, something with licensing or patent issues with Qualcomm.

Oh I mean not on wifi - calling I am just talking about 4G LTE. I mean I have the note 3 right now. LOL. I know super old. I can talk on the cell network 4G LTE and surf the internet at the same time. Can you do that with the Unlocked Version and the Sprint Version or one or the other?

Are you serious. I will be giving up call over data? WHY? Is this like that for Verizon and AT&T? Have they all lost call over data or do they just not want you to be able to do it?
Should I keep my Note 3 for that very reason?
Does any phone like the S8 or S8 Plus have call over data?

Verizon Unlocked N9 on T-Mobile

Hello guys,
I am getting a really good deal on a Verizon version (Unlocked) on Craigslist. I am on T-mobile.
I do not intend to unlock bootloader or root etc.
Have a few questions:
1. Will I be able to use all functionalities on the Verizon phone (like I would get on a T-mobile version)?
2. Do these Verizon versions come with removable Verzion apps?
3. Is there a way to flash T-Mobile firmware on the phone? Will this process make the Verizon version "like" T-Mobile version?
4. Anything else I should be aware of (like Volte/Wifi Calling/HD voice etc.).
Thanks a lot!
Did you ever find answers to some of your questions?
It is obvious he did absolutely no research. Are you waiting for somebody to do all the reading for you?

I just noticed that searching on XDA has "search all post text" disabled by default which yields no results. Turning that on brings in a bunch of relevant posts. XDA should look into that.
i have a verizon n9 , i put my Tmobile sim card, got 4G, however, if you make a phone call, all the 4g functions shut off , even the browser.
any solutions

GSM/CDMA question, Want to switch from Verizon to..not sure yet

I'd like to find out for sure, if I can use my phone I've purchased through Verizon, with another company. It's a Moto G6 and in the settings, it gives the option for either GSM and CDMA.
I am confused because a person I called (customer service) said I could not use that phone. Can someone that knows about this situation tell me for sure?
Thank you for any information you can provide
Moto G6 V. 8.0.0
Attached is where I see the choices but I may be misunderstand. I guess Verizon can offer CDMA or GSM so another company that only offers GSM may not allow me to use my phone.
Depends on the model, the XT1925-6 has bands for all carriers in the US and should work on any of them providing it is unlocked, just get a SIM kit from whatever carrier and you're good to go. I'm using an unlocked XT1925-6 on a Verizon SIM through Straight Talk, had no problems getting it to work.
To find your specific model:
Settings > About phone > Hardware information, and it will be listed under SKU.
If you bought it through Verizon it might only have Verizon specific bands. They probably will unlock it for you though if you want to use their towers through someone else.
FYI straight talk is the cheapest for bulk data out there. Mint mobile (TMobile) is cheaper for casual data use. TracFone (Verizon) is cheapest if you rarely ever use data. The XT1925-6 model works on all of them.

It should, best source I found for the bands on the XT1925-12 model is here: [can't post link, just google XT1925-12 and click on the first one from BestBuy.com]
Looks to carry all the same bands. So if you can get Verizon to unlock that phone you should be able to use SIM cards from any other provider on it.. if Verizon's cool about unlocking their phones. You'll have to call Verizon and ask about that. Good luck.

Advice for getting a v40

I want to get a v40 to replace my Redmi Note 7
I use T-Mobile but know not to get the T-Mobile v40. So I was curious if it would be better for me to get a different one and unlock it or what should I do?
Any advice would be great because I don't want to put my self in a pickle where I have a nice paperweight
No need to get a TMo version.
A cross flashed Sprint V405UA to LG v405QA will work on TMo and get all TMo bands, plus TMo VoLTE and TMo VoWi-FI and TMo HD Voice. I know because that's the model I bought, cross flashed, and use on TMo.
I see no reason why a cross flashed Verizon or ATT wouldn't be equally good. But I can't speak there from personal experience.
But there's no cross-flashing possible on a TMo version. Once TMo, always TMo.

I saw you in some other posts and I was hoping to get you to respond to this. Thank you. I'll have to keep my eye out to see if I can find a sprint one. I like my redmi note 7, but there are many features that I want that it just simply doesn't have. But are there any other weird quirks I should know? Again, thank you.
Thanks for kind words. I seem to have a bit more time on my hands now ... I wonder why ....
The only weird quirks I think are worth mentioning is that it is not easy to root and install TWRP. Several have had issues doing so. It can be done, I and others are living proof, but it's not for the fainthearted. You'll have to bounce back and forth between several threads to get it right. There's no one comprehensive guide. If you're not looking to go that route, there really are no quirks.
As for sourcing one, I picked up mine, a mint condition device, off of eBay for $145. A steal for a phone of this caliber. They seemed to have upped the price in the meantime.
[NG]Owner
Troubles with getting TWRP working don't bother me. I don't mind that. I love messing with things a little too much. Also, with that link that you sent, although the listing said you can't use third party software to unlock it, you still can. Correct? (Well the listing you sent said that it was sprint only, but not specifically unlocked. But it showed me a similar one that is $170 that says it's sprint locked)(also that because it technically isn't software that you're using to unlock the device.)
And I do wonder why you would have more free time on your hand, I could never tell why...
In many cases, these eBay vendors have no idea what they are selling or what "tethers" come with which phones. See here's the thing. If the device is paid off, it can't/shouldn't be carrier locked. You own it free and clear, and should be able to put it on any carrier with which the phone is compatible.
From reading these forums, I knew I could convert (cross-flash) a v405UA (Sprint) device over to a v405QA (US version) which would enable more bands (that I needed/wanted for my eventual migration to TMo). And if the device in that listing was somehow actually carrier locked to Sprint, I knew I could get Sprint to unlock it. I had Sprint, I knew I was going to use the v40 for a while on Sprint, so I could easily verify its carrier unlocked-ness, and could correct it if needed.
But I didn't need to. The v405ua (which was originally attached to Sprint at some time in the past by a different customer) came to me carrier unlocked. Three weeks later, I had that same device, crossflashed, rooted, with TWRP, on TMo happily making use of the extra TMo bands, VoLTE and VoWi-Fi, and HDVoice (none of which a non-crossflashed v405UA could).
[NG]Owner
Ok, so if it isn't paid off then the seller is selling a bad phone, and they should list that in the description.
I'll buy the $170 mint condition v40 because it's a good price for the phone, and I'll have something to mess with. Thank you, again. I appreciate all the help.
It'll be nice to have a nicer phone again. I loved my S8 before I broke the screen, and after I had modded it.

Trying to get Wifi Calling to work (AT&T unlocked on T-mobile)

Hey all,
So I have an unlocked AT&T V40 ThinQ that I have service on at T-mobile. Cannot get wifi calling to work (it's grayed out in the options). I spoke to T-mobile tech support who sent me to LG tech support. LG said to call T-mobile tech support. I have no issues with the phone other than this. Do I have any solutions other than getting service on AT&T? Any suggestions are welcome, and thank you in advance.

I spoke to T-mobile tech support who sent me to LG tech support. LG said to call T-mobile tech support. I have no issues with the phone other than this. Do I have any solutions other than getting service on AT&T? Any suggestions are welcome, and thank you in advance.

So my at&t device is flashed with pie US OP version kdz. I use it on t-mobile with mvno mint mobile. To get wi-fi calling all I needed to do was go to mint mobile website account and select option for it. Boom, done, have wi-fi calling and volte works also.
It *sounds* like for you, running at&t kdz, then the only way it would work is with at&t? I don't really know, but if yer not connecting to at&t, why keep all their bloatware on yer phone? Why not just flash the us op kdz?

Yes, this post is what you want to follow to use lgup to crossflash to a different rom.
This link is to the rom you would want to flash. The latest version is Pie, but 10 should be coming out soon.
cheers
