Told you Sprint didn't have an exclusive on the LG V30+. I knew by the way Sprint worded that bogus press release, which everybody fell for.
Today is October 6. U.S. Cellular is even selling it BEFORE Sprint!

If I buy the v30+ from us cellular or Sprint, do you think I can use it for t mobile network with the same coverage as if I bought it from T-Mobile themselves?

It seems to have the same bands as the T-Mobile version minus band 71.

Yes, what U.S. Cellular is selling does not have LTE band 71. But while this is the US998, it's not the official carrier unlocked US998. (When you buy this phone from U.S. Cellualr, pay in full, upon request U.S. Cellular will unlock it for you to use on other carriers.)
The official carrier unlocked version has not been "announced" by LG yet -- even though it's listed on B&H website, and we all know it's coming. When it's announced and released (probably end of October, according to B&H website), we are hoping
LG will have filed an FCC amendment to enable LTE band 71 on the US998. An amendment can be filed less than 2 weeks from actual release.
Or that with root, we can enable that band by flashing T-mobile radio over it.
The official carrier unlocked version will not need to have a carrier unlock it, of course. It will be unlocked out of the box. After that, then LG will add that model to the official bootloader unlock list. (EDIT: in another forum, someone said the U.S. Cellular model my not be eligible for official bootloader unlock, even though it's the same model number.)
If you buy this phone from U.S. Cellular right now, pay for it in full, get it carrier unlocked, you would still need to wait for LG to add the US998 to the official bootloader unlock list, to be able to root. Earlier this year it took them SIX WEEKS after the LG G6 US997 was released to be add that phone to their bootloader unlock list.
So, while we know this U.S. Cellular US998 right now does not have LTE band 71, it's possible the official unlocked US998 will have it -- or it can be enabled after root. Exciting times right now, with lots of stuff happening!
To get really specific, here you go:
If you buy this phone right now from U.S. Cellular -- and get unlock code from U.S. Cellular -- it will work on all U.S./Canadian carriers including T-mobile. However, right now it will not have T-mobile's LTE band 71 (600 MHz) which T-mobile has installed in a very few places. (It does have the T-mobile band 66 which is something else.)
If you buy this phone right now from U.S. Cellular, you will have the LG V30+ with 128GB internal storage + microSD card. Will T-mobile eventually sell the V30+ version of this phone, maybe in November, December? Possibly.
If you buy this phone right now from U.S. Cellular, YES you will have a phone that will EVENTUALLY have bootloader unlock and root. You will just have to wait for it a few more weeks, for LG to add it to the official bootloader unlock list. (EDIT: in another forum, someone said the U.S. Cellular model my not be eligible for official bootloader unlock, even though it's the same model number.)
Will T-mobile LG V30 ever have root? Probably not, unless LG/T-mobile has changed their minds since the T-mobile LG G6 was released.
If you buy this phone right now from U.S. Cellular, will you EVER have LTE band 71? Right now, we don't know. Before release, LG can file an FCC amendment to add LTE band 71 to the official carrier unlocked US998 or it possibly LTE band 71 can be enabled on US998 via root. Since this U.S. Cellular US998 and the official carrier unlocked US998 are the same hardware, you can flash any firmware meant for one over the other. IF the official carrier unlocked US998 ever gets LTE band 71, one way or the other, then YES so will this U.S. Cellular phone. (EDIT: in another forum, someone said the U.S. Cellular model my not be eligible for official bootloader unlock, even though it's the same model number.)

Well of course you'll be able to. Sprint will be merged with TMo at the end of this month. So anyone buying a Sprint phone right now is gonna be kinda screwed when Tmo converts all the CDMA to GSM. I would hold off buying any Sprint phones for at least a year to be safe

No, it will be locked down. The LG G6 was. They go by IMEID or something.

I just purchased the US998 from US Cellular for use on T-Mobile. It was carrier unlocked out of the box and works perfectly on T-Mobile.
I definitely want band 71 so I'm wondering how long it will take to know if this model can be boot loader unlocked and rooted..and also if band 71 can be enabled.

Yes, the U.S. Cellular US998 model (in both V30 andV30+) is the UNofficial carrier unlocked version. It has all the GSM/CDMA/HSPA/LTE bands listed below -- but it won't be eligible for bootloader unlock and root. It is SIM card unlocked (carrier unlocked) if you pay in full. There's no guarantee LG will sell the OFFICIAL carrier unlocked US998 in the V30+ (128GB) configuration.
We're hoping the official US998 can have LTE band 71 enabled on root or that LG enables it via FCC amendment before release end of this month.

Can we unlock so v30 of other carriers will work for at&t? I saw that v30 for other carriers such as T-Mobile and sprint is cheaper.
Verizon and U.S.Cellular LG V30 will work already on any other carrier. They are SIM card unlocked.
T-Mobile will SIM card unlock if you pay off the phone. But depends on which carrier you want to use it on. T-Mobile doesn't have CDMA, so no Verizon for T-Mobile H932.
If you want to confirm if another carrier's phone will work on your network, go to https://willmyphonework.net/
Tmobile has a page that list requirements that must be met before they will unlock it for you https://support.t-mobile.com/docs/DOC-1588

You can unlock T-mobile locked V30 and use it with AT&T because both are GSM phones. However, you can't do the same with Sprint devices because Sprint is a CDMA network. But, some devices have both GSM and CDMA capabilities. So if you plan un getting a Sprint phone, make sure it can support GSM networks (SIM cards as well).
You can check here which are CDMA networks and will probably not work with AT&T SIM cards https://www.unlockunit.com/blog/cdma-networks/
Can I use the existing SIM card from my current Verizon LG V20 phone & retain my same phone number with the new LG V30 model?

Yes. If you have Verizon VS996 or carrier unlocked US998. It doesn't even have to be an "original" VS996 or US998, but any North American variant CONVERTED to VS996 or US998.
But why are you resurrecting a YEAR OLD thread?
Some of the answers on here are way outdated. Now I have to spend time correcting them. Arggggh. People stop digging up old threads!

Yes you can. It's called Frankenstein and I wrote the Guide. Any North America V30 (EXCEPT for T-Mobile H932) can be converted to any of the carrier unlocked models.
Favorite is to convert SPRINT LS998 to some other variant, like carrier unlocked US998.
You can get mint 128GB LS998 v30+ for less than $310 with FREE SHIPPING. Convert it to US998 v30+ with all the US998 bands and fastboot flash commands. PLUS, it's now carrier unlocked/SIM card unlocked.
Bootloader unlock it using WTF, root it, boom ready to go.
Not your fault you had a wrong "November 2017" answer brought to light now in November 2018. Somebody dug up an old thread and the information you gave at the time was correct. But lots of development in the past year. We now have Frankenstein and WTF.
So In the last few weeks i have tried the Essential nice phone really like it.. but the camera on it sucks.. I purchased a one plus 5t but didnt work on verizon... So there is a bunch of v30s on various sale groups by me for half price but they are for tmobile im guessing from that buy one get one sale going on.. Can it work on verizon and if so what needs to be done to make it work?
thanks in advance.

No. Just like AT&T and T-mobile use HSPA as backup bands when LTE is not available, Verizon uses CDMA. The T-mobile H932 doesn't have CDMA. While you CAN enable Verizon LTE band 13 for instance via the "hidden menu" trick on the T-mobile H932, you can't enable CDMA.
The phone that would work for you is the U.S. Cellular V30 or V30+. It has the CDMA and LTE bands you need for Verizon.
Next week, the "open market" official carrier unlocked LG V30 US998 will be released and that will also have all the Verizon bands you need. It's basically the same model as the U.S. Cellular but will also be eligible for bootloader unlock, root, etc. If you don't care about those things, then go ahead and get the U.S. Cellular model US998. It's the "unofficial" carrier unlocked model, also numbered US998. It has GSM/CDMA/HSPA/LTE.

ahh dam ok, thanks for your reply.. Ill wait til amazon gets the v30+
So now that all variants besides the T-Mobile V30 have root I am hoping maybe that opened up more options to get more USA bands working on my India H930DS.
I read a few threads about adding bands on older phones with root access particularly this one for the Galaxy s5:
https://www.google.com/amp/s/forum....o-add-rf-lte-frequency-bands-to-t2886059/amp/
It details the whole process of adding extra 3g and LTE bands on a rooted s5 with custom rom/kernel. He also states it should work on any Qualcomm based devices.
My question is will something like this work on newer devices such as my H930DS V30+?
Also i am not sure but i am assuming the "ids" he mentions in the steps 17-23 are going to be different?
Can any experts here confirm weather the process in the thread i linked would be relevant for my purposes or any other methods that can take advantage of root to add/enable more bands?
Ah come on. Someone at least give me some hope that i can keep this phone.
Back in 2015 we tried that Qualcomm method with Moto Quarks (Moto Maxx, Moto Turbo) and it didn't work. I don't know about LG phones.
I think no only one is answering because they really don't know.
All I know is when you flash Sprint LS998 to US998, it takes on those bands and loses a couple of Sprint bands. Sprint guy @JWnSC reflashed Sprint modem and got them back. So it IS possible to add/remove LTE bands from the V30. Whether it's possible in the way you need, I don't know. You're crossing hemispheres.
Alright thanks for the answer. I just don't want to go through the whole process of bl unlock and root just to find out I can't even get the tools to connect to the phone and read/write the bands or something stupid like that.

I can add, when I flashed the VS996 modem back after BL unlock/root, the hidden menu did not show the additional bands that, according to GSMArena, should have been present (46 & 66). Instead, it showed the native US998 bands and my connection was screwed up.
It may have been something I did or didn't do... I don't know.

Here's what I don't understand. If you flashed the H930 over your H930DS phone, these are the bands you should have...
If you have"H930" (either actual or converted), you will have these bands:
2G GSM: 900 / 1800 / 1900
3G (HSPA): 850 / 900 / 1900 / 2100
4G LTE: 1/2/3/4/5/8/12/17/20/28/38

So what bands are you missing that you need to add? I know Sprint users want LTE band 26 and 41, which can be added back by flashing the Sprint modem. I know T-mobile users would love LTE band 71 (probably not going to happen). Verizon users want Wi-Fi calling back and that's been solved.
But you SHOULD already be getting LTE on AT&T or T-mobile on the existing bands.

That is the problem I'm encountering. I flashed the H930 kdz on my H930DS and I am still not getting the H930's bands, only the H930DS'. I'm not sure if I did something wrong here. I also tried to use partition dl mode in LGUP to flash only modem, xbl and xbl2 from the H930 kdz but still no change. Any help?
I don't know, maybe 66? I think 66 is extension of band 4 right? Something I read somewhere. All I know is nothing I tried would let me get anything better than a 2g/edge connection at home and a 3g connection in town. It was constantly only being able to get 2g that bothered me. If I could have gotten a consistent 3g/hspa connection I would have been more than happy with it. Anyways I just gave up and sold it.
Which bands are you missing?
The bands listed for the H930 earlier is not correct either. It supports a few more than that.
---------- Post added at 08:56 PM ---------- Previous post was at 08:52 PM ----------
According to GSMArena, India uses these bands: LTE 850 (5), LTE 1800 (3), LTE 2100 (1), LTE 2300 (40), LTE 2500 (41). All of them except 41 is supported by the H930DS. It sounds more like your APN settings were wonky.
All I know is with the same SIM card I am getting LTE+ connection on my new essential PH1 in the same spot I was only able to get 2g connection with the h930ds.
So has anyone figured out a way to add LTE bands to their US998?
I am stuck with AT&T H931 firmware mainly because I don't want to lose band 30. The more I dig into the AT&T firmware, the more I dislike what the big brother did.

Because your H930DS is not made for North American carriers. It's missing most North American carrier LTE bands. So, all you could receive is 2G bands.
Has nothing to do with SIM card, has everything to do with you not researching what you bought. .
You should have bought Open Market US998 V30+.

You can root and debloat the AT&T firmware if you wish.
So my phone has been running great since the conversion and still flys on ATT LTE, however I am a Mobile rep and I switch carriers on occasion, hence why I was wondering if the US998 modems actually enables the 800mhz CDMA band and allows me to use the verizon LTE bands.
Im not new to flashing and trying things out, and I can easily get my hands on a verizon android sim (yes there is a difference) to test anything.
Thoughts?

The US998 is the "carrier unlocked" version, and many people have used US998 on Verizon, so there's no question the US998 has that band.
Converting any other North America phone to that should let you have all those bands of the US998.

Ill have to test APN settings and clean boot with a verizon sim then. Ive tested a sim and it pulled phone number, but was still looking for signal.
Try making a backup in TWRP, and then flash JUST the Verizon system partition and see what you get.
rild is the daemon that talks to the modem, and Verizon may be slightly different.

Im sorry my English is not very good. But is unbelievable that H931 doesn't show UMTS 900 band on official description and doing the Frankenstein conversion you can add that UMTS 900 band. So it means that is disabled wow.
Another question. If the H931 AT&T model is not unlocked and I do the convertion then will be unlocked? Or I have to buy the unlock code for the IMEI???

OP, can you confirm that you can use LTE band 13 on your H931 (AT&T) Frankenstein phone? I converted my VS996 to US998 10b, unlocked bootloader, updated to 20e (KDZ), and rooted with magisk 17.3. I can use T-Mobile VoLTE but can't connect to their LTE band 12. I've tried the US998 Hidden Menu hack by using T-Mobile's LTE band menu and selecting LTE bands 2, 4, 12, 66, and 71. When I leave only band 12 selected I only get 3G or 2G EDGE. Maybe T-Mobile doesn't like my phone's IMEI as it's from Verizon. On AT&T, I never got stable LTE because my old G4 was from T-Mobile, and it always dropped to 3G after a while. If hardware isn't the issue then it leads me to believe T-Mobile whitelists only their branded devices for band 12.

I get the success message when clicking on band 13 in the hidden menu. I am using the latest stock US998 rom. Its given me the best reception and still runs fluid as can be.
Also, did you just insert your sim card into the phone from your previous device or did you manually enter your IMEI to your phone number in your T-Mobile account? Is the sim card brand new or several years old? Not being nosey or questioning your ability, just making sure your device properly activated on T-Mobiles network for best network performance. I don't think T-Mobile is picky with verizon IMEIs as 99% of verizon phones are sim unlocked out of the box and T-mobile likes to advertise towards verizon customers.

My T-Mobile service is actually through Tracfone. I activated it on a G5 H830 (TMO), and then moved over to a V20 H910 (AT&T). I did notice poorer reception on the V20 because I rarely locked into band 12. I always had excellent reception on the G5 and frequent band 12. I tried this SIM just now on a Canadian G6 H873 from Videotron, went into hidden menu *#546368#*873# -> Field test -> Modem settings -> LTE Band Selection -> Band 12. I instantly got Band 12 locked in, but went back to Automatic mode: (Field Test -> Network Mode -> Automatic). This band selection menu leaves you locked to that LTE band only, and you can't select multiple, so I went back and got Band 4 which is stronger in my house. If it were rooted, there's a hidden LTE menu that allows you to select multiple bands (through "tmo only" and iot menu, search LTEBand and BandSelection in shortcut master lite when rooted). Doing this on my VS996 -> US998 it falls back to 3G as it can't find Band 12 for some reason. I've tried wiping the modemst1 and modemst2 partitions to no avail. I'm now on the AS998 (ACG or C-Spire?) 20b KDZ. It should be identical to the LS998 (Sprint) modem and supports bands 2, 4, and 12. I kept TWRP recovery by not flashing the recovery in LGUP, INSTANTLY GO INTO FACTORY RESET (Power + Vol up) or else recovery will be wiped, flashed magisk 17.3, Disable_Dm-Verity_ForceEncrypt, lg-rctd-disabler, erased modemst1/2, and booted up. The hidden menu in the AS998 has all bands greyed out in the hidden menu only accessible through root, and the LTE band selection menu reports FAILED on all bands, so it's locked to the stock bands of the AS998/LS998. I'll report later on my findings.
TWRP Terminal command to wipe modemst1 and modemst2:
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1 bs=16384
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2 bs=16384

I'm confused. Do they want band 13 or band 12? They started talking about band 13, then started talking about T-mobile band 12.

I want band 12, I just found it amazing that OP has band 13 and CDMA on his H931 -> US998. Mainly because the H931 is GSM and shouldn't come with an ESN/pESN, just IMEI and MEID. And due to Verizon being picky about devices. I had an RS988 G5 and that didn't work well with them.

When you convert it with Frankenstein, it converts to have all the bands.

Not mine, I converted a VS996 -> US998 and don't get band 12 or 17. I the same SIM on a G6 from Canada (H873) and band 12 works on Tracfone via T-Mobile and on AT&T (prepaid).

No one else has said this, in fact the opposite.
I'm not talking about T-mobile at all, as they have put specific requirements on their band 12 due toWifi calling, etc.
But many are using us998 on T-mobile, whether converted or original.
That doesn't prove you don't have band 12. Also, ATT no longer calls band 17 as 17. On all newer phones, it's band 12, as 17 is a subset of 12. If you look at the H931 specs it says "12" , not 17. Their 12 is fully interoperable with T-mobile band 12 and includes 17.
