I just ordered an "unlocked" G5 H830 on Ebay, after carefully checking the LTE bands on the FrequencyCheck. I know I need bands 2 and 17 because I used the LTE Discovery App to determine that my carrier (AT&T US) provides LTE on in my area. But I just realized that other sites show different LTE bands for the H830 model...
FrequencyCheck LTE 1/2/3/4/5/7/12/17/30 (I hope this is right because I need Band 17)
The LG Website LTE 2/4/5/12/29/30, Roaming 1/3/7/20, and CA
Autoprime's helpful G5 thread LTE B1/B2/B3/B4/B5/B7/B12/B20
Can anyone confirm which of these is correct? Or verify that the H830 cannot use Band 17? Has anyone succeeded in adding LTE bands to the G5? Perhaps as described in this thread about phones with Qualcomm chipsets?
The moral of the story - check multiple websites when selecting a model with the right frequency bands for your carrier/area!

I know it's been a month
For att, band 12 support is equivalent to band 17 support. If you see a phone with band 12, it'll work on att's band 17
(12 is a superset of 17. Att has deployed mfbi on most of their network so that 12 phones can connect to their 17 network
Reverse is not true- 17 phones cannot connect to 12 networks since 17 phones are missing the nonoverlapping stuff in 12
That saying , I can't help with lte bands (h830 may or may not be missing 29/30 which att uses as a third lte layer. Not that important since you can rely on band 12/17/5 as first layer, band 2/4 as second layer)
I have V30+ (H932 /T-mobile version) I already get T-mobile Permanent Unlocked on my device.
Just realized that the bands availability for this device is not as many as Samsung Note 8 (T-Mobile version).
eg. no LTE band 8. The spec stated it has
GSM 850/900/1800/1900 MHz
WCDMA B1/B2/B4/ B5;
LTE B2/B4/B5/B12/B46/B66/B71 (USA-Tmobile)
Roaming LTE B1/B3/B7/B20/B38/B39/B40/B41
I will use this phone in the country that need LTE band 8.
by reading this thread;
https://forum.xda-developers.com/lg-v30/help/increasing-data-speeds-t-mobile-t3703325
It seems , I have found a way to get into engineering mode to get into band selection option and turned on the band I need.
but I have a doubt if this phone will be working especially LTE band 8 in my destination country where I have to Travel. (there is no LTE band 8 on LG V30+ t-mobile)
Can some one confirm and test to by switching SIM card, (must be temporary /permanent unlock), let say turn on band 17 from ATT since default T-mobile version is not available,
The area where I live T mobile and ATT use LTE band 4 so it is hard for me test myself with ATT SIM card if band 17 is working after I turned on that band.
Thank you

LTE band 17 is a subset of LTE band 12. All new AT&T phones now only list band 12, because it includes 17.
A lot of AT&T customers missed this news apparently:
AT&T’s 700MHz Systems Now Interoperate With Band 12/17 LTE

Here are the specs for the AT&T LG V30 H931 -- straight from both the LG and AT&T websites. DO YOU SEE BAND 17 listed on this AT&T phone?
No. Because LTE band 12 is listed -- therefore no need to list LTE band 17.
http://www.lg.com/us/cell-phones/lg-H931-Black-lg-v30
IF you go to the AT&T website to BUY an LG V30 H931 from them, here are the bands they show you are on the their own phone. Slightly different order from the LG.com website -- but still NO band 17. No need to show LTE band 17, since LTE band 12 is there!
https://www.att.com/cellphones/lg/v30.html#sku=sku8510583
The V300 I received from HK didn't have the B20 LTE band on the spec sheet.
But when i enabled it in the engineering menu, it worked perfectly with European networks.
There are some apps that give you the ability to record the bands number you encounter and log them.

Read my reply again. 17 is subset of 12. Even new AT&T phones no longer show "17", since they will now show 12. If you have 12, then you have 17. New AT&T phones will no longer show separate 17.
Even the AT&T LG V30 doesn't show 17. Why? Because 17 is already IN 12. (Like sugar is in cookies.)
But I'm repeating myself over and over. Just go read that post again.

There is no reason not to believe your point, as I already said "good to know"
I don't need to argue about it .
In technical point ATT band 17 is already covered by band 12 (T-mobile) which 700Mhz ( a )
for some people they just read band 17 is band 17 not band 12. and obviously they are thinking it is different with limitation of technical knowledge.
I just pointed out the frequencycheck.com
https://www.frequencycheck.com/carriers/at-t-united-states
I guessed ATT can't just stated they are using band 12 which they don't have (extended range LTE 700Mhz a)

AT&T now calls it band 12 on their phones moving forward.
Older phones will still show "17".
That site you keep giving link to is not an AT&T website and you have no idea when it was even last updated. I'm not even going to bother going to that site because I know I'm right. I really don't care what they say. They haven't kept up with current development.
It's why the AT&T LG V30 H931 on the AT&T website doesn't have LTE band 17 listed, but has LTE band 12 in the specs instead.
There are apps like LTE Discovery that will show you what bands you are on, and even keep a log as you travel around.

On my US998, here's the bands I am getting as I travelled to work yesterday morning. I was getting LTE bands 2 and 12. As expected it's now LTE band 12, not "17" -- because AT&T doesn't call it Band 17 anymore (except older phones will still show that). All new AT&T phones or new phones compatible with AT&T (like the US9998) will show LTE band 12.
https://www.reddit.com/r/tmobile/comments/47blo3/eli5_band_12_vs_band_17/
Band 12 consists of the frequencies 698-716 and 728-746. This band is the only band that covers the 700a block that T-Mobile uses, and also happens to cover the b-block and lower-c-block that AT&T uses.
AT&T is upgrading its network so that it can handle Band 12 phones, since Band 17 is a subset of Band 12. This means that people will be able to use T-Mobile phones on the AT&T network.
Additionally, AT&T's phones will begin coming with Band 12, which means they can be used on the T-Mobile network.

The hardware may be identical but the firmware is not. Yes, it will work on AT&T. However it does not have some of the new minor AT&T bands the AT&T version has, like LTE bands 25 and 30. Seriously, you won't notice they are not there. There are no "standalone" locations where AT&T ONLY has LTE bands 25 and 30. Those are "filler" bands to help with congestion and are still being rolled out.
Just like a few years ago when LTE band 5 was first being rolled out. Back then, if you got bumped off the LTE bands 2, 4, 17 (now being called LTE band 12 by AT&T, discussed in depth in threads elsewhere), and your phone didn't have LTE band 5 in areas where it was present, you got temporarily bumped to HSPA. You STILL had carrier signal and went back to LTE as soon as possible.
The important ones are still 2, 4, 12 (Formerly called 17 by AT&T. But band 17 is a subset of the larger LTE band 12, so no need to list both. That would be like saying "includes Georgia and Atlanta." Atlanta is IN Georgia. As of early 2017, all new AT&T phones ONLY list LTE band "12", and no longer list LTE band 17.) -- and now "filler" LTE band 5 is in a lot of places. The T-mobile H932 phone has all four of those(2, 4, 5, 12/17), so yes it will work well on AT&T.

Now, the T-mobile version has a nifty menu where you can ALLEGEDLY add LTE bands. Whether this actually lets you receive those bands is still up for discussion. We tried enabling T-mobile menu with LTE band 71 for instance in the rooted US998 and no one yet has reported success.
Could you add AT&T 25 and 30? It might let you in the menu, but whether it really worked or not, you would have to tell us.

AT&T is T-Mobile's domestic roaming partner in some areas. Although band 25 and band 30 aren't available where I roam on to AT&T's network (southern West Virginia). It would make sense that they should work for that reason.
LG though has gone out of their way though to limit working bands on the V30. For some reason, the DS version doesn't want to work with T-Mobile USA bands even though the bands show up in the menu. I don't personally own one but from many years of tinkering with devices. The V30 is the first device I am aware of that lists without modification bands in the engineering menu that actually don't seem to work.
For what it's worth, I have the unlocked/rooted US998 running on AT&T. I've tried to add those extra LTE bands as ChazzMatt described. Band 30 in my case is not enabled or working by default. It allows you to add them, but I haven't got them to work. So I am left wondering if it is hardware difference between the unlocked version and the official AT&T version, or simply firmware? Since LG hasn't officially made bootloader unlock available for the US market unlocked models, there aren't a lot of us to experiment with.
Let's see if I can be coherent about the following.
A previously locked AT&T V30, unlocked via email with code from AT&T.
Proceeded to take this (now unlocked) phone to Verizon. Their phone calls work fine but SMS and data does not work.
When checking the IMEI, their system says invalid IMEI.
When using an AT&T SIM, everything works.
So, unlocking a locked AT&T phone really does nothing at all -- or what is occurring here ?

Most GSM carrier branded phones (AT&T and T-Mobile) don't work on CDMA carrier networks (Sprint and Verizon). Or at least don't work fully. Some phones direct from vendors for the US market (such as the V30 variant US998, Pixel devices and others) work on both GSM and CDMA carriers, while others (such as OnePlus) only work on GSM networks.
In addition to network/band limitations of the phone hardware, CDMA carriers need to specifically add the phone's IMEI to their network in order to provision service. Just popping in a SIM card usually isn't enough.
I am surprised you are getting any service at all, which means your phone was probably unlocked alright, and Verizon must have added it's IMEI to their network. I would say you can try a carrier wipe (dialing ##SCRTN#) but I don't know if it will work on your phone, and you may be required to enter your MSL. So DON'T try it unless you have that.
You should be able to switch to T-Mobile, though, just with a SIM card and entering APN settings.
Edit: If you haven't already performed a Network settings reset (Settings/General/Backup & reset) I would do that first.
Edit2: Regardless of everything, I would love to hear the outcome, particularly if you perform a carrier wipe (##SCRTN#).

Hello I have a Lg v30 with tmobile. I am the owner of the phone and have no outstanding balance with them however they refuse to allow me to unlock the phone. Is there any capacity for me to unlock it otherwise? Id rather not pay for a suspect service and obviously those who do it through a service have some kind of process to doing so and I was wondering if you could illuminate that for me.

Did you buy the V30 from T-Mobile directly? T-Mobile only unlocks devices fully paid off by the original purchaser on the active account they purchased it on as long as they don't have a past due balance. You would use the T-Mobile Unlock app that comes preinstalled on the device to remove the SIM lock, if you meet all of those requirements. Otherwise, you are stuck using a third party unlocking service.
ANSWER BELOW.
But First... I hate it when people dig up very old threads. This thread was started (Feb 2018) back before we had root for ALL V30 and TWRP-flashable zips for most of them. Most of the information in this thread is outdated and will confuse people reading it.
Second, this thread has NOTHING to do with procedure for carrier unlocking/SIM card unlocking T-mobile H932. So, not sure why this question was asked here....

You can only carrier unlock/SIM card unlock the T-mobile H932 through T-mobile servers. Mostly by using the T-Mobile unlock app.
If you cannot do it that way, there are a few 3rd party providers who can spoof your T-mobile H932 to another T-mobile phone model and help you unlock it.
You have to downgrade to Nougat for this to work. They will remote into your PC, with your phone connected and do stuff. But they are still using the unlock app with T-mobile servers.
THIS DOES NOT INVOLVE ANY "CODE". If anyone tries to sell you a "code", that is a scam.

Hello I have a Lg v30 with tmobile. I am the owner of the phone and have no outstanding balance with them however they refuse to allow me to unlock the phone. Is there any capacity for me to unlock it otherwise? Id rather not pay for a suspect service and obviously those who do it through a service have some kind of process to doing so and I was wondering if you could illuminate that for me.

Just adding to the spot-on advice already provided:
In addition to the phone being paid off, the account on which it was purchased must be in good standing, AND the phone must have been active on T-Mobile for at least 40 days (postpaid) or 1 year (prepaid). See T-Mobile's complete requirements here. If you fulfill those requirements, they generally will unlock the phone.
If they either refuse to unlock it or are unable (the latter being a common occurence) you want to file an FCC complaint. It's not a very big or complex process, and it will escalate the matter to T-Mobile's Executive Office. Those guys can unlock the phone in a heartbeat, even when the rest of T-Mobile says it's impossible. I've used them, and so has others. Nice people too. But first make sure you genuinely fulfill their requirements, otherwise you're wasting their time, which I'm sure they don't appreciate.
Otherwise you have to use a 3rd party service as described by @ChazzMatt. The phone must be rooted (last I heard). Check the thread linked below (which would have been much better for this discussion).

I'm debating between buying the LG V30s, G7, and S9+. I would prefer the LG ones because they support QC 3.0, but I travel internationally all over the place and need a phone with a ton of LTE band support (but I'm currently in the US).
I need 6GB of RAM, 530+ ppi, IP68/67, USB-C QC, and great cameras, so this is all I have to select from:
https://www.gsmarena.com/results.ph...mm=selected&sIPCerts=5,6&sOSes=2&idCardslot=1
The S9+ has 26 bands.
The LG V30s (US998R) only seems to have 11.

The LG G7 (G710ULM) is worse at 9.

I have a hard time believing that LG would create a different chip for all their different regional models of the same phone. The chip must support all the bands but a ton of them must get disabled in firmware. Is there any way to unlock them?

which specific bands are you looking for? The samsung exynos phones typically support a lot of bands, just not the us specific ones. Because of whatever contract samsung has with qualcom, their chipset doesn't support any of the sprint or verizon lte/cdma bands.
The us specific phones typically have the radios crippled and each rom supports bands for that specific carrier. the samsung s9+ snapdragon 845 (us version) has the same issue as the lg phones + they can't be rooted or bootloader unlocked.
the lg v35 unlocked supports a lot of bands, but again, no root or bootloader unlock
the oneplus 6t supports lots of bands and can be unlocked but its not a premium phone and is missing a lot of other features like sdcard, ip rating, qi charging, etc.

I'm not looking for any specific bands since I don't know where exactly I'll be traveling to. I just want as many bands as I can get just in case. On the USA side I just want TMobile support.
The US S9+ versions still seem to have a ton of band support, no? Their only issue is they can't be rooted, but is this a permanent problem or do all Samsung phones eventually get root?
If I wanted an LG G7 or V3x phone with 6GB and all that jazz I mentioned, do I have any options for one that had tons of bands and is unlockable? A European version perhaps?

There is sim unlocked and bootloader unlocked which are two different things. Two phones closest to what you are describing would be the unlocked s9+ from b&h and the lg v35 unlocked. Both will support around 22 bands and will be sim unlocked. Currently neither phone can be bootloader unlocked.

If you want information about any of these phones your best bet is to go to that section of the forum and ask your questions there....
While most decent 2017/2018 phones already support B12 & B66, not a lot of non-TMO phones support B71 yet. If you want to keep your new phone until 2019+, the phone should support it. That means your choice would be limited to the ones in TMO B71 list
FWIW, LG V30 H932 (TMO): WCDMA B1/B2/B4/ B5; LTE B2/B4/B5/B12/B46/B66/B71 LTE Roaming B1/B3/B7/B20/B38/B39/B40/B41

I travel a bit too but you'd get too many hits and misses with LTE if your destinations are still unknown.... I'd get the phone with best value proposition for daily TMOUS (IMO that's currently a used H932 in mint condition, easily found), and just deal with LTE abroad as the issue comes (get a local SIM, rent/buy a hotspot if needed, etc - you probably knew that prepaid data packs are normally much cheaper outside the US. I have a hotspot specifically for use in Asian countries I travel to).

Whereas for me on AT&T, the best value daily phone is the US998.

2G GSM: 850/900/1800/1900 MHz

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Only T-mobile subscribers would use LTE band 71, and most T-mobile phones still don't have it.
Don't forget about HSPA... Last time I was in Brazil, where their main LTE bands 3 & 7, my phone at the time had those, as does the V30. But STILL most of the time I was on HSPA due to their telephony infrastructure in rural areas. Point is, having good selection of HSPA bands is still your best "international" fallback plan for phones that don't have 99 LTE bands.
Don't obsess over having every LTE band for every country. For proof of that, look at T-mobile. TONS of people on this forum have the US998 on T-mobile. Their phones work just fine.
Thanks. I really want 6GB of RAM though, and the V30 doesn't have it. The other LG phones with 6GB of RAM either don't seem to have many bands or have a locked bootloader or both.
I ended up buying the Samsung S9+ G965F/DS. It's got root, 6GB RAM, and all the other features I'm looking for except QC 3.0. It's kind of a shame because I've been a Samsung user for the last 10 years and was adamant I wasn't going to get another.... but here I am.

Yeah, I'm in a bit of a tough spot.
I need 6GB because the only reason I'm upgrading from my current TMobile S5 is because 2GB just doesn't cut it for modern apps anymore and 4GB just isn't future-proof enough for me. My S5 doesn't have band 71 either but the day-to-day sluggishness of not having enough memory is FAR more of an issue than band support.
I *want* to get the unlocked SnapDragon S9+, but it's not rooted or bootloader unlocked yet and I don't know if it *ever* will. Even the S8+ still has problems with bootloader unlock and root, right? The only reason I'm still running the S5 is because the ability to unlock and install LineageOS saved it and allowed me to squeeze two more years out of it.
So can anyone say with 95%+ confidence that the unlocked USA SnapDragons will have BL unlock and root?
Ok, I'm now even less confident that the S9+ SnapDragons will get bootloader unlock and root.
Even looking back at the S7, LineageOS is only supported on the Exynos models and none of the SnapDragons:
https://wiki.lineageos.org/devices/herolte
https://wiki.lineageos.org/devices/hero2lte
Same for the S8s.
I'm guessing that this trend will only continue for the S9s.

The T mobile version sounds great to me because it would work great in Italy where I travel often. However I am planning to convert the H932 to us998 by flashing with LGUP for rooting. Does that mean I will loose the extra bands of H932 and have US998 bands instead?

1) You will brick your phone. T-mobile H932 has different RSA encryption than the other North American V30 variants.
This is why H932 can't use WTF method to install TWRP and root. It cannot be Frankenstein'ed to US998 for necessary fastboot flash commands.
2) Converting (Frankenstein) any North America V30 to another (not possible with T-mobile H932) makes it THAT phone, including all bands. After bootloader unlock and root, Verizon and Sprint users will often flash their VS996 or LS998 modems back.

That's NOT what you said. You said you were planning on converting T-mobile H932 to US998. That Root LAF method for T-mobile H932 by @runningnak3d has nothing to do with WFT method -- which for some V30 (particularly North American variants) mean at least temporarily converting to another model (like US998).

I think you are somehwat confused. AT&T H931 has always had LTE bands 3 & 20. Note both links below are to LG.com website and those specs have been there since DAY1.

4G LTE Bands: 1/2/3/4/5/7/12(17)/20/29/30/38/39/40/41/66
LTE bands 3 and 20 have also always been in the US998 specs:

US998
CDMA: 800 MHz CDMA
2G GSM: 850/900/1800/1900 MHz

4G LTE Bands: 1/2/3/4/5/7/12(17)/13/20/25/66
Why not just buy US998 to begin with? Or buy cheaper variant like LS998 and convert to US998. I'm not understanding your logic. With US998 you get LTE bands 3 & 20, have CARRIER UNLOCKED, have fastboot flash commands so you can also bootloader unlock and root if you wish.
With H931, you are carrier locked to AT&T. Yes, you can get that unlocked -- but then you have no access to firmware updates as AT&T only gives updates via OTA to AT&T customers. This is why everybody and their brother CONVERT H931 to US998. To carrier unlock, get fastboot flash commands, AND get easy updates.

The G965F/DS is not snapdragon. The only samsung snapdrag phones that are unlocked are the hk and cn versions which again have crippled radios.
The best snapdragon 845 with unlocked bootloader and root would be the one plus 6 and thew newly released one plus 6t.
The lg v30s does have 6gb of ram and most likely can be unlocked using wtf method. But the bands will be more limited and its snapdragon 835.

Did LG really produce all these V30 and + variants will different hardware (radios), or just cripple them through firmware? Would be great to be able to unlock the phone's capability with a firmware flash.

Hi I am planning to get a LG V60 Verizon Variant (network unlocked) but I have a problem with the band frequencies because the LTE band that is supported in my countrie are Band 3,28,41. I want to know if I inserted a sim (from my country) will I be able to access the bands that is listed as roaming in the LG V60 tech spec sheet without activating data roaming? or does the band only activates in data roaming?
Yes but do not have B41 so check region where you can use B41. with B28 and B3 no problem
